Overclocking a Mining GPU - The Geek Pub

RX 5700 (NON XT) Mining Performance (7/28/2019)

**Disclaimer**
[Still testing, and Tuning but the new AMD RDNA Architecture is new and not only is AMD still optimizing drivers, the mining Developers who DO NOT get GPU's sent to them, are still working on optimizations. Please be patient with me as I continue to test and allow sufficient time for new miners to be developed.]
Same stuff different day just as with the RX 590 Fatboy and RTX 2080, I will be testing the RX 5700 over time as new miners come out, to compare price to performance for mining. Below are some of my results when testing the new AMD RX 5700 (Non XT) graphics card mining performance, now I was only able to get a few working. I did some videos on its Gaming performance and the "SoftPowerPlayTables" mod from Igor's Lab at Tom's Hardware, which allowed the RX 5700 to really stretch its legs. Allowing this Non-XT model to surpass the RTX 2060 Super and even get on par with the first Gen RTX 2070. Moving forward, as new miners are release I will update my numbers and test when I can.
***UPDATE: 7/31/19 - New Phoenix Miner 4.5c still only getting 2 - 4 Mhs, XMR Stak 2.10.7, only Algo that will run is RYO
***UPDATE: 9/15/19 - Updated Power Draw numbers, as my Watt Meter died, new one in and retested Algos below
***UPDATE: 12/14/19 - Updated and added Algos as miner support was implemented. Retesting with Radeon Adrenalin 2020 driver
***UPDATE: 1/22/19 - Updated additional miners as support was implemented. Retesting with Radeon Adrenalin 2020 driver (20.1.3)

Why is the RandomX algorithm being hyped to the moon?

TL;DR: don't assume the average return from mining RandomX will be higher than the current CryptonightR algorithm. Hold back your excitement for now.
I think we all need to bring something to our attention. Over the last month, there have been so many topics and comments here on MoneroMining about the new 'RandomX' algorithm. This algorithm is supposed to be launched a couple of months from now.
There are many questions like "is this a good hashrate for my CPU"? "What's your power usage on RandomX"? "How can I tune my CPU for RandomX"? "How would the algorithm perform on this hardware"? I think these are great constructive comments that are at the heart of what miners stand for. We miners love optimizing our rigs and educating ourselves on technological trends.
But I've noticed many questions such as "what parts should I buy for a RandomX mining rig"? "Is an AMD Ryzen 9 3900x a good investment"? "What parts will give me the most profit when RandomX launches"? Many of these questions are asked with very little research.
I think there's a gold fever brewing behind some of these comments. The kind of motives that have bankrupted many miners in the past bubbles.
As we have seen in 2014 and 2018, anybody who enters the crypto industry with an 'I want easy profit' attitude almost always goes bankrupt. They buy coins or hardware at the peak of the bubble. Sometimes they get lucky and sell their coins or rigs right before the crash (only to get burned in a future bubble later). But most of the time, these new users lose most of their investment.
As a veteran miner, a lot of alarm bells ring in my head when I read these kinds of RandomX hype posts.
I have no reason to think CPU mining will be more profitable on RandomX than on the current CryptonightR.
In the GPU mining community, I have the feeling that there's a lot of resentment over the 2018 crypto recession and the whole 'ASIC miner invasion'. I think people here are feeling burned over their losses last year and the evil ASIC takeover, and want an opportunity for the little guy to start mining again. So we're falsely seeing the RandomX ray of hope as a floodlight, and getting overexcited.
And in general, the ordinary person cannot make a significant, steady profit in the crypto mining industry. The guy who wrote that thread is very rich and even 100 GTX 1080 Ti's cost nothing to him. The reason he became wealthy is because he avoided get-rich-quick gimmicks back in the day (like the dotcom sites) and focused on learning technology for the future. Mining will not make you rich, and especially not RandomX coin tossing.
If you love RandomX, build your rig now, keep benchmarking and undervolting and have fun at it. But if you just want profit, wait until RandomX is up and running. And consider all the risks involved with a new algorithm and commercial mining in general.
So I hope we can all reconsider whether we're excited about RandomX for the right reasons. Let's try to avoid jumping to conclusions about profitability and hold off on the Newegg 'checkout' button. Even though 12 cores at 70 watts sounds awesome. Happy mining!

Debunking myths about mining and GPUs

E: Going to bed, will contribute more tomorrow. Thanks for the discussion!
Myth: Mining is more stressful than gaming. Fact: It depends. During the old days, this was plausible, because older GPUs (Pre-polaris) are/were bottlenecked by core clock when mining the most profitable coins. Thus, miners overclocked and overvolted these cards quite frequently, especially with cheap electricity. This meant that those cards were often run hot, pushing the limits and stressing VRM and fans quite a lot. Nowadays, ethash (Ethereum) is the most profitable algorithm for AMD cards 99% of the time, and newer GPUs (Polaris) are limited by memory bandwidth and latency. Miners can underclock core to the low 1100MHz range before seeing performance drop. To save power, miners who know what they are doing also undervolt, since it is no longer necessary to sustain a high core clock. Thus, it is quite feasible to run polaris cards below 70C at a reasonable fan speed. However, dual mining (mining more than one coin at once) does increase power consumption by up to 20%, and there are also idiots who run their polaris cards OCd while mining. With the exception of a few idiots, miners treat their Polaris GPUs pretty much the same; that is, running underclocked and undervolted 24/7 with a memory strap mod and mem OC. On the other hand, former gaming cards are highly variable in use cases. Some gamers leave their cards at stock settings, some undervolt, and some OC and/or overvolt. Most of the time, these cards are thermal cycled far more often than mining cards, which is known to weaken solder. Another thing to consider is that manufacturers have learned (somewhat) from their mistakes of putting shit tier fans in GPUs, and many fans on modern GPUs are ball bearing and/or swappable. Even some budget cards, such as MSI Armor, use decent ball bearing fans. Bottom line: the risk of buying mined Polaris cards is not as high as the risk of buying older mined cards. I would not be against buying mined polaris cards, but it's not necessarily better than buying a gamer's card instead. At the end of the day, it depends more on how the owner treated it than what they used it for.
Myth: GPUs are obsolete because of FPGAs and ASICs Fact: Mostly false. Older algorithms such as scrypt and SHA256 (lite/doge/feathebitcoin etc) are no longer feasible to mine with GPUs, but there have been multiple algorithms since then that are built to deter ASICs; most of the time it is done by making it memory-hard because designing an ASIC with high memory throughput is considerably more expensive to design and manufacture. Many devs prefer their blockchain to be ASIC resistant to avoid the concentration of power problem that Bitcoin is having nowadays, where a giant, near-monopolistic ASIC manufacturer (Bitmain) is causing a lot of (subjective) controversy. Blockchains based on ethash (Ethereum and its forks), equihash (Zcash and its forks) and cryptonight (Monero and forks) are some examples, but there are scores of other shitcoins and a few other algos that are GPU dominant. It is almost impossible that there will be another ASIC takeover, which is what was responsible for the stop in GPU demand in the bitcoin and litecoin days. Bottom line: ASICs no longer threaten GPU miners, or the demand for GPUs
Myth: Ethereum switching to Proof of Stake will kill mining soon Fact: Doomsayers have been preaching about proof of stake since late 2015. It has always been "coming soon." The fact is, the Ethereum roadmap goes from proof of work (mining) -> Casper (mining + PoS) -> Metropolis (PoS). Currently, the release date of Casper is not even announced yet, nor is it being tested in a (public) testnet. Proof of Stake might one day take over, but mining is here to stay for a while yet. Another thing to consider is that there are tons of other GPU mineable blockchains, and although Ethereum is biggest, it is certainly feasible that mining stays profitable even after Ethereum goes PoS (if it ever does). However, it is possible that profits will be low enough to discourage new miners. Bottom line: It's very unlikely. E: I screwed up the roadmap; here is a better source than me with some interesting information: https://www.ethnews.com/ethereums-vitalik-buterin-gives-keynote-on-metropolis
Myth: The current Ethereum demand spike is a bubble Opinion: Honestly, I don't know. I would not be surprised if stricter regulations on ICOs come sooner or later, which would fuck with Ether prices. There is also the inherent volatility of cryptocurrencies. However, it is also possible that blockchain technology continues to gain traction; that is, the price could just as easily go up as go down. Although it's fun to read about other people's opinions, only time-travelling wizards can tell you when it will become economical again to upgrade your poor HD5770. Bottom line: No one knows.
Myth: Miners will "steal" all the RX Vegas Fact: Only a reckless miner would buy Vegas on release, since mining performance is not known. In fact, it is possible that it can't mine at all (or at some stupidly low speed) until devs add support to existing miners. It would be even more reckless than gamers who buy without seeing benchmarks, since at least gamers can expect the games to actually run. It's also not necessarily the case that Vega will be good once miners do add support. Maybe there will be enough reckless miners to affect supply, maybe not. Of course, it is possible that miners will deplete the supply after it is demonstrated that Vega is good for mining. Bottom line: Most miners won't preorder, but it's possible that a significant number will. E: Important to remember that even if mining demand isn't high, doesn't mean that supply will be plentiful.
Myth: Nvidia cards SUCK at mining Fact: Mostly false. They USED to suck in the old pre-Maxwell days, but now they are actually more efficient at mining Ethereum and Zcash compared to AMD cards, even after both cards are undervolted. The flipside is that they (used to) cost more for the equivalent hashrate. For reference, my old 5xRX470 rig drew just under 800W when mining ETH only and hashed at 150MH/s. My current 6xGTX1060 rig draws just over half of that (<450W) and hashes at about 135MH/s. Certainly not as good in raw performance, but they are viable nonetheless, especially given the AMD GPU shortage. In fact, Nvidia cards (1060 and especially 1070) are becoming scarce as well. Bottom line: Nvidia is still the underdog when it comes to mining, but far from irrelevant nowadays.
Myth: 4GB cards will be obsolete for mining soon Fact: FALSE. The Ethereum DAG is not even 3GB yet, and won't be for a few months. The recent reports of 4GB Polaris cards slowing down soon due to DAG size is caused by limited TLB capacity, not VRAM restrictions. Polaris cards will still be able to mine ETH forks such as Expanse and UBIQ without diminished speed, and even if they are used to mine ETH, it is not that much of a performance hit at first. It would certainly not make polaris useless or undesirable for mining anytime soon. Tahiti GPUs already suffer from this issue and Hawaii is the most resistant to this issue. Have not benched Nvidia at a later epoch.
Myth: Creating miner-bashing posts on Reddit will help alleviate the GPU supply problem Fact: False, you are simply giving cryptocurrencies and mining more exposure to the general public, increasing demand.
Myth: Mining-specific GPUs will solve the shortage problems Opinion: There's not enough info to tell yet, but I am a skeptic for the following reasons. First, no display limits the resale value of the card for obvious reasons. IMO, the whole point of crypto mining from a profitability standpoint is to have a hedge against coin volatility (hardware is still worth something if the coin crashes). Otherwise it is much less effort to just buy and hold the coin. If the hardware is useless without demand from other (significant) sources, then it doesn't make much sense to buy it unless the price is extremely low. I'm sure that cost-downing the PCB and warranty will make for a cheap card, but it has to be extremely cheap and plentiful in supply, or else miners will buy whatever they can get. I could envision "failed" chips (not meeting spec of consumer editions) being stuck in miner cards, but I doubt there are enough to meet demand without ramping up production as a whole, which carries its own risks. I guess that it would help a little, but probably not solve the problems. Alternatively, since modern GPUs are bottlenecked by RAM when mining, it might be enticing to miners to have the fastest (GDDR5) RAM on the market (probably the 9gbps chips from the 1060 6G 9gbps edition, although I don't have one to test). However, my previous points still apply; buying such a card without display outputs carries a big risk. Bottom line: It's not a great idea, unless they are super cheap or use really good RAM.
Hope this helped; if you have any further questions I will try to answer them. I'm both a gamer and miner who uses both AMD and Nvidia roughly equally and don't favor one group over another. I've mined and gamed on all high end AMD GPUs since Tahiti (except Tonga) and all Pascal cards except 1050ti.

I hate my Fucking Mining Rig - Short Story of my mining adventure (Don't really hate it)

Wanted to write a short write up on my journey of Crypto mining for some of the newer people and people who want to get into it. Not trying to discourage anyone from starting, but want to show the progression of a newbie.
So I am a good with computers and learned of Bitcoin when it was about $7 a coin. Laughed at the idea of some computer doing some math and getting some BS currency. Million dollar mistake on my part, but hindsight is always 20/20.
Anyways, Learned about ethereum in May. Bought some at around $180 and bought all the way up to $330. Now to the mining rig. Ran all of the calculations and with a 180 hashrate and 900 watts I was gonna get 6-7 Eth per month. Shit was gonna be profitable in under 3 months. I was gonna be a fucking crypto allstar and be rich as fuck!
Bought all of my parts literally the day before they were nonexistent. Literally bought the last RX480's from Amazon. Here is a list of my parts.
Asrock board Pentium dual core processor 4 Gb of ram 128 gb SSD 1200 watt Rosewill PSU 6 Sata to Molex PCI Risers (Junk) 6 RX480's - 2 Asus Strix, 4 Gigabyte Total cost - Roughly $2,500 (Pennies compared to my future ROI)
Please keep in mind that I am not posting every single miner issue that I ran into such as fucking with Wattman for a few weeks before learning about Trixx and Afterburner.
I've built computers before, so that part wasn't hard. Set everything up and get windows 10 running.
Problem 1 - Computer doesn't see all of the cards. Had to run the drivers a few times and tweak some shit, but got all 6 cards seen.
Miner hurdle (See what I did there) but off to the races. Let's get this bitch running so I can begin planning my retirement.
Get Claymore running, Got Trixx to overclock. Ran my cards at -96, 1200, 2200 fans at 85% (Cause I'm cool like that.) Major stability issues from the start. 1 card (Asus) would crash all the time. Didn't know about the watch dog feature in claymore that would restart my rig when a card crashed. Great feature but my computer would go into this state of having power, but not loading the operating system. Even if it did restart, most of the time claymore would get stuck right before setting the dag's and would just lock up. (Claymore program is awesome by the way, this was my rigs fault)
Could not get this fucking Asus card to stop crashing, even on stock settings. Sent the bitch back RMA style. Asus said something was wrong and sent me a new one.
Awesome, lets get this bitch running. I need to start looking at sick houses in Costa Rica to move to once I am rich as Fuck!
New card makes things better for a few days. Not 100% stable but better. Go to vegas for a driving thing (Race cars - Future rich guy stuff) and this mechanical demon starts crashing every few hours. Luckily I had Google remote desktop installed so I could log on and restart it or change settings in Trixx. Had to have my GF unplug it and plug it in a few times.
Get back home, fuck with this thing but still random crashes on random cards. Decide it is the PCI risers. Contact seller who will send me some more for free. Slow boat from china took two weeks to get them. They arrive but still some of them are bad. Can't seem to piece together 6 good ones.
Did some research online (Ethereum Forum and Reddit) and decided to get some new style of risers V007 6 Pin to Sata ($70) and they take a month to get here. Plug them all in and they seem to be working much better. Decent stability, But I ain't got time for fucking stock bios. Let's ramp these bitches up and get 32 MHs per card at 600 watts from the wall!
Actually flashing the bios was pretty easy. Thank you 6 pound 9 ounce baby jesus! Long story short had some major stability issues and bounced around with some different timing straps before finding the right ones. (Uber 3.1 for Samsung memory)
So now that we've got some good hash speeds and decent stability let's ramp this private ATM up a little bit by dual mining some Decred. Get dual mining up and running. go to sleep. Wake up the next morning expecting to see myself on the top 100 forbes list. look at my mining rig stats on my phone and see that it died roughly and hour after I went to sleep. Walked toward my rig on the red carpet I had just installed and saw that it was off. Flicked on the light to check it out. No light, WTF? Well I'll be god damned, no power in this whole fucking room. Checked my breakers and sure enough this metal motherfucker tripped my breaker.
No worries though. I'm smart as fuck. I'll just undervolt the shit out of it to get the power down. No way in hell I am just mining ether. I'm going balls to the wall!
As you can expect I had many days of stability issues and tripped breakers. But fuck it, I have homeowners insurance. Burning it to the ground will be covered. (Didn't happen)
My surge protector must be maxed out. Let's buy a bigger one ($25). Same issues.
Fuck Decred, I'll mine SIA, less power. Damn I'm smart.
Rig is more stable with Sia and no tripped breakers. Family medical emergency, have to fly north for a few days. But my rig has been fairly stable and I've got remote desktop if anything goes wrong.
Arrive at airport, check mining stats, rig is down. No worries remote desktop. FUCK, not responsive, no way to remote into the rig and no way to remotely power it off and on.
Lost 4 days of mining. But no worries the difficulty is only, Holy shit that's high! But the price of Ether will make up for it. Ether crashed to the $200's. Oh well, maybe a 10 room house in Costa instead of a 12. No sweat.
Get back to my house and this whore of a machine is just sitting there in a computer coma. It's on but it's not. LED lights glaring at me like "Fuck you human, I ain't doing your stupid math problems!" Fuck you machine, I'm your master. You will do my math problems and you will fucking like it.
My AMD Drivers seem to disappear and the computer goes into a coma like state. Someone on Reddit suggested using the 16.9.2 drivers. Installed and they worked better.
Still random crashing. This shitty PSU must be maxed out. Fuck you PSU, I'm getting you a little brother (EVGA 750 gold $120.)
What do you mean you have to jerry rig a second PSU so it starts without being connected to a motherboard? 2 more hours of my life wasted.
But finally some stability. On my way to being fucking rich. I start looking at people in bentley's and can only laugh. You dumb fuck, I'm gonna be way richer then you. Gonna get a Bugatti for each day of the week.
Damn this difficulty is a bitch. Fuck you Genesis Mining and your pallets of GPU's. You're killing me smalls!
But anyway, on my way to rolling around in my fuck you money!
Fuck you dag file 135, you're killing my future millions. Fuck you dag 138, you dropped me to 167 mhs.
Thank god AMD was there to save my ass with their dope ass blockchain drivers.
download, run DDU, Restart, install drivers, restart, run pixel patch, restart. Perfect, I'm in the money now! I can taste the caviar and champagne already.
Now my cards only run 4 Mhs each. WTF? Try a bunch of the other new drivers. Same shit. Roll back to 16.9.2 and they run fine, just at 167 instead of 180.
Someone on a forum said he had the same issue and did a fresh install of windows 10 and it worked.
So I'll just reformat my SSD (Windows wouldn't do a fresh install within the operating system. Fuck you Bill Gates! Gonna buy you once I get this thing running at 180.)
Format SSD, plug back in, throw in my gangster ass boot USB drive. Ramdisk error. Fuck you Bill Gates! Reformat SSD multiple times, lots of forum reading. Install windows from another computer through command prompt (I'm a coder now as well.) This shit has got to work, I did it in command prompt bitches!
Same fucking error. Now down to an 8 bedroom house in Costa and only 6 Bugattis.
Let's try unplugging my 6 cards and see if that works. Thank you 6 pound 9 ounce baby jesus. Windows installed.
New drivers work and I'm back at 180! Raking in the cash now.
With those speeds my Asus cards crashed. Had to dial down the hashrate to 177.5 for them to be stable. So now going to use some commands in claymore to run the Asus cards at lower speeds while letting my other cards mine harder.
I wrote this to let people know that mining isn't all Bugatti's and caviar. These machines are fickle little cunts that do what they want. No system is the same. So when you post on a forum, people will give you advice on what may work. But what works for them, may not work on your rig. In the end it's up to you to figure it out.
I have spent countless hours after work and on weekends working on this bitch. Hell I've probably spent a few hours just staring at it and thinking about all of the ways I could destroy it slowly.
While I love Etheruem and do value the knowledge gained, I would have made more money just buying Eth and holding.
The guys you see on youtube building sick rigs with crazy specs have been at it for a while. They have worked through the process and know how to solve all of the problems. You have not and will have to work them out on your own.
My whore of a rig will pay for itself soon. But I would suggest that if you want to start building a new mining rig. Check the difficulty chart and make sure you have tons of free time to fuck with it.
I'd post my wallet address for donations since I just saved you $2,600. But I am afraid hackers will steal my monies :)
Hope you enjoyed my mining life story from the past few months.

Anybody here interested or already involved in mining with there GFX card?

I just ordered a evga 1080 gfx card. Initially the purchase was to replace my gtx 970, but giving a second thought as I am thinking to mine crypto currency to recover the cost of the 1080 in a period of 4-6 months mining 24x7 as I have a secondary system at my place. Any of you already mining or interested in mining with there recently purchased gfx card ? If u interested pls comment below so that we can communicate further.

Problem 1 - Computer doesn't see all of the cards. Had to run the drivers a few times and tweak some shit, but got all 6 cards seen.
Miner hurdle (See what I did there) but off to the races. Let's get this bitch running so I can begin planning my retirement.
Get Claymore running, Got Trixx to overclock. Ran my cards at -96, 1200, 2200 fans at 85% (Cause I'm cool like that.) Major stability issues from the start. 1 card (Asus) would crash all the time. Didn't know about the watch dog feature in claymore that would restart my rig when a card crashed. Great feature but my computer would go into this state of having power, but not loading the operating system. Even if it did restart, most of the time claymore would get stuck right before setting the dag's and would just lock up. (Claymore program is awesome by the way, this was my rigs fault)
Could not get this fucking Asus card to stop crashing, even on stock settings. Sent the bitch back RMA style. Asus said something was wrong and sent me a new one.
Awesome, lets get this bitch running. I need to start looking at sick houses in Costa Rica to move to once I am rich as Fuck!
New card makes things better for a few days. Not 100% stable but better. Go to vegas for a driving thing (Race cars - Future rich guy stuff) and this mechanical demon starts crashing every few hours. Luckily I had Google remote desktop installed so I could log on and restart it or change settings in Trixx. Had to have my GF unplug it and plug it in a few times.
Get back home, fuck with this thing but still random crashes on random cards. Decide it is the PCI risers. Contact seller who will send me some more for free. Slow boat from china took two weeks to get them. They arrive but still some of them are bad. Can't seem to piece together 6 good ones.
Did some research online (Ethereum Forum and Reddit) and decided to get some new style of risers V007 6 Pin to Sata ($70) and they take a month to get here. Plug them all in and they seem to be working much better. Decent stability, But I ain't got time for fucking stock bios. Let's ramp these bitches up and get 32 MHs per card at 600 watts from the wall!
Actually flashing the bios was pretty easy. Thank you 6 pound 9 ounce baby jesus! Long story short had some major stability issues and bounced around with some different timing straps before finding the right ones. (Uber 3.1 for Samsung memory)
So now that we've got some good hash speeds and decent stability let's ramp this private ATM up a little bit by dual mining some Decred. Get dual mining up and running. go to sleep. Wake up the next morning expecting to see myself on the top 100 forbes list. look at my mining rig stats on my phone and see that it died roughly and hour after I went to sleep. Walked toward my rig on the red carpet I had just installed and saw that it was off. Flicked on the light to check it out. No light, WTF? Well I'll be god damned, no power in this whole fucking room. Checked my breakers and sure enough this metal motherfucker tripped my breaker.
No worries though. I'm smart as fuck. I'll just undervolt the shit out of it to get the power down. No way in hell I am just mining ether. I'm going balls to the wall!
As you can expect I had many days of stability issues and tripped breakers. But fuck it, I have homeowners insurance. Burning it to the ground will be covered. (Didn't happen)
My surge protector must be maxed out. Let's buy a bigger one ($25). Same issues.
Fuck Decred, I'll mine SIA, less power. Damn I'm smart.
Rig is more stable with Sia and no tripped breakers. Family medical emergency, have to fly north for a few days. But my rig has been fairly stable and I've got remote desktop if anything goes wrong.
Arrive at airport, check mining stats, rig is down. No worries remote desktop. FUCK, not responsive, no way to remote into the rig and no way to remotely power it off and on.
Lost 4 days of mining. But no worries the difficulty is only, Holy shit that's high! But the price of Ether will make up for it. Ether crashed to the $200's. Oh well, maybe a 10 room house in Costa instead of a 12. No sweat.
Get back to my house and this whore of a machine is just sitting there in a computer coma. It's on but it's not. LED lights glaring at me like "Fuck you human, I ain't doing your stupid math problems!" Fuck you machine, I'm your master. You will do my math problems and you will fucking like it.
My AMD Drivers seem to disappear and the computer goes into a coma like state. Someone on Reddit suggested using the 16.9.2 drivers. Installed and they worked better.
Still random crashing. This shitty PSU must be maxed out. Fuck you PSU, I'm getting you a little brother (EVGA 750 gold $120.)
What do you mean you have to jerry rig a second PSU so it starts without being connected to a motherboard? 2 more hours of my life wasted.
But finally some stability. On my way to being fucking rich. I start looking at people in bentley's and can only laugh. You dumb fuck, I'm gonna be way richer then you. Gonna get a Bugatti for each day of the week.
Damn this difficulty is a bitch. Fuck you Genesis Mining and your pallets of GPU's. You're killing me smalls!
But anyway, on my way to rolling around in my fuck you money!
Fuck you dag file 135, you're killing my future millions. Fuck you dag 138, you dropped me to 167 mhs.
Thank god AMD was there to save my ass with their dope ass blockchain drivers.
download, run DDU, Restart, install drivers, restart, run pixel patch, restart. Perfect, I'm in the money now! I can taste the caviar and champagne already.
Now my cards only run 4 Mhs each. WTF? Try a bunch of the other new drivers. Same shit. Roll back to 16.9.2 and they run fine, just at 167 instead of 180.
Someone on a forum said he had the same issue and did a fresh install of windows 10 and it worked.
So I'll just reformat my SSD (Windows wouldn't do a fresh install within the operating system. Fuck you Bill Gates! Gonna buy you once I get this thing running at 180.)
Format SSD, plug back in, throw in my gangster ass boot USB drive. Ramdisk error. Fuck you Bill Gates! Reformat SSD multiple times, lots of forum reading. Install windows from another computer through command prompt (I'm a coder now as well.) This shit has got to work, I did it in command prompt bitches!
Same fucking error. Now down to an 8 bedroom house in Costa and only 6 Bugattis.
Let's try unplugging my 6 cards and see if that works. Thank you 6 pound 9 ounce baby jesus. Windows installed.
New drivers work and I'm back at 180! Raking in the cash now.
With those speeds my Asus cards crashed. Had to dial down the hashrate to 177.5 for them to be stable. So now going to use some commands in claymore to run the Asus cards at lower speeds while letting my other cards mine harder.
I wrote this to let people know that mining isn't all Bugatti's and caviar. These machines are fickle little cunts that do what they want. No system is the same. So when you post on a forum, people will give you advice on what may work. But what works for them, may not work on your rig. In the end it's up to you to figure it out.
I have spent countless hours after work and on weekends working on this bitch. Hell I've probably spent a few hours just staring at it and thinking about all of the ways I could destroy it slowly.
While I love Etheruem and do value the knowledge gained, I would have made more money just buying Eth and holding.
The guys you see on youtube building sick rigs with crazy specs have been at it for a while. They have worked through the process and know how to solve all of the problems. You have not and will have to work them out on your own.
My whore of a rig will pay for itself soon. But I would suggest that if you want to start building a new mining rig. Check the difficulty chart and make sure you have tons of free time to fuck with it.
I'd post my wallet address for donations since I just saved you $2,600. But I am afraid hackers will steal my monies :)
Hope you enjoyed my mining life story from the past few months.
Edit - Had an Asus card die on me and replaced it with a 1070ti. Nvidia is so much easier!
My rosewill 1200 watt PSU melted the 8 pin port and cable. Had to drop $300 on Amazons last 1300 EVGA.
But my rig has well surpassed it's cost and is still mining away like a champ. Eth for life!

Is it worth mining with an R9 390? & What program should i use?

I see all these people saying they make 2 pounds a day mining with GTX 1080's, Can i get similar mining performance with an R9 390? What programs do i use? & How much exactly will it raise my electricity bills up to?

A quick guide to GPUs and cryptocurrency.

There seems to be a lot of misinformation going on about cryptocurrency and how it ties into the new and used GPU markets. I want to try to help alleviate some of the false rumors as well as put together a quick resource to answer any questions someone may have. This is not to sway anyone to or away from crypto or anything like that. I just keep seeing threads that go something like this:
OP: GPU prices are so high right now C1: Oh it’s because of bitcoin OP: elaborate C1: bitcoin is mined 24/7 using huge GPU farms. The miners snap up any and every new GPU they find. OP: well I’ll just buy used! C1: bad choice jabroni. The miners run these cards so hot and heavy that they’ll instabreak as soon as you buy them. OP: oh well when will it stop? C1: bitcoin just crashed so we should see some new GPUs in stock soon OP: thanks dude!
This is an exaggerated exchange, but it is based on some of the more common things I see sometimes and it gets the point across. The fact is, a lot of people that comment are trying to be as helpful as possible, and that is absolutely a good thing. The problem comes when trying to water down the information to make it easier to comprehend for a beginner. That’s where I’m hoping this guide comes in. I’ll start off by explaining the process of mining as concisely as possible while still keeping all of the relevant information. After that, I’ll try to debunk/explain some of the myths surrounding mining and GPUs. Let’s hop in.
Mining in a nutshell:
Cryptocurrency mining is the act of using a cpu, GPU, or an ASIC (specially designed device) to solve mathematical equations that verify transactions. That’s a very general definition that we can work with. Within the general aspect of mining, there are different algorithms that are used for different currencies. Some currencies use the same algorithm, so you end up with more currencies than algos. Some algorithms are “ASIC-resistant”, so the best way to mine is with a GPU.
Now how do you actually get paid by mining? That’s simple. Generally speaking, any time any cryptocurrency is sent anywhere it must go through a verification process and will incur transaction fees. Who gets those fees? The same people that verify the transaction, miners. That simplifies the process a good bit, but it is still truthful.
That’s a good bit of background information. Let’s traverse a bit deeper and cover how somebody gets into mining. I’ll start by saying this: Hardly anybody mines Bitcoin. A little more emphasis for the people in the back. HARDLY ANYBODY MINES BITCOIN. Why is that? Because Bitcoin is not profitable unless you are using a high dollar ASIC. That is beyond the scope of this guide, so I’m not going to go there.
There are two ways for the Everyman to mine: choosing a coin and mining through a pool, or using what I call a “smart miner” like NiceHash. For the sake of simplicity, let’s use NiceHash from here on. NiceHash is mostly on par with the profitability of pool mining, and it is also a lot easier to set up. This simplicity is inviting to beginners and experts alike.
With NiceHash, you never actually mine coins for yourself. You sell your hashing power to those that are buying hashing power. You switch between whichever algorithm is most profitable and mine whatever coins the buyers are paying for, however, you are paid in bitcoin. Confusing? Cool, let’s get simpler. Say you have any amount of GPUs in a rig. In order to mine, download NiceHash, set up your account, and press the start button. Now you’re mining with power! In order to make this profitable enough, you’re going to want a rig with multiple GPUs. A common goal is 6-8 GPUs per motherboard w/ multiple motherboards.
So we’ve got all the background we need for now. Let’s tie in some market information. Currently almost all crypto currencies are down significantly, but that doesn’t change the fact that it’s incredibly volatile and could skyrocket in the next week. We have to deal with the fact that yes, crypto is down, but most people will continue mining because it will inevitably go back up. We may potentially see a drop off in miners buying cards until the return of investment goes back up. It’s kind of dismal right now.
Myth Madness:
M: Bitcoin is causing GPU prices to skyrocket.
E: Let’s replace a few words here. This is more accurate: “cryptocurrency is a big factor in the increase in GPU prices.” This is better, but still doesn’t tell the full story. While cryptocurrency is jacking up the demand for GPUs, a RAM shortage as well as the fact that manufacturers just can’t keep up is keeping supply down.
M: Miners snap up every available new card.
E: This one is pretty true, however, most miners aren’t just snapping up these cards at MSRP, they’re paying the same price everybody else would pay. In the market’s current state, the higher prices of GPUs hurt the return of investment especially when the dollar value of cryptocurrency is down.
M: Miners are only interested in AMD!/Nvidia!
E: this one is a common misconception. Some cards do outperform others, but that does not mean 6 rx 580s will outperform 6 gtx 1080s. Generally speaking, the most powerful card for gaming will be the best performer for mining. A 1080ti will earn around 6 USD per day while a 580 may earn 3 USD per day. Return of investment is actually pretty similar if you go by msrps. You pay more, you earn more to an extent. Most miners that are in it purely for profit are going for 1060 6gb and up, or 570 8gb and up.
M: Mining cards are run at full power 24/7 and are useless after they’re done with them.
E: The 24/7 part is true. Most rigs run constantly, but almost all miners undervolt their cards. The power consumption doesn’t do much to the hashrate, but it cuts into overall profit by drawing more electricity than it actually needs. In addition to this, heat is still an enemy as it is with a high performance gaming rig. To combat this, most rigs are in a cold room with as much airflow as possible in the form of multiple case fans, external box fans, ceiling fans, even portable AC units pointed directly at the cards. Miners are all about protecting their investments. The only wear that could be a problem is fan wear, which can be an easy fix.
M: This will pass when bitcoin crashes.
E: Cryptocurrency is in it for the long haul. 2017 was honestly the first year of widespread acceptance of crypto. It’s best to look at return of investment when talking about crypto and GPUs. With crypto down, GPUs won’t be bought as much. GPU prices go down, return of investment gets back to what it was. More GPUs are bought. It’s a huge ebb and flow type of thing.
Let’s go back to the original exchange from the beginning and see how someone could potentially answer the OP.
OP: GPU prices are so high right now. C1: unfortunately, we’re in a phase where manufacturers can’t keep up with the demand for them. OP: why’s the demand so high? C1: a big reason is cryptocurrency. Crypto miners are able to make a big profit off of mid-high end cards, so they buy them as fast as possible. Lower end cards are effected as well because gamers that can’t get the mid-high range are settling for low range to fit in their budget. OP: Well how about used? C1: If you’re getting a current gen Card, you should ask plenty of questions regarding the conditions it was in. Last Gen cards like a 970 or 980 are probably alright and will rival the performance of some 10 series cards. OP: What if I wait it out? C1: I wouldn’t advise waiting it out. It could take several months for this phase to pass. I would buy a 970 or 980 to hold over until prices even out.
That’s a lot more informed as well as being a lot more helpful to the OP. The best advice I can give if you want a high end card is to be vigilant about deals. Some places are offering GPUs at MSRP if you buy other components with it. That’s a great option if it’s your first build. All in all, we’re in a pretty troublesome time for PC building with the price of ram going up as well as the price of GPUs.
I don’t claim to be an expert so if there are any corrections or additions that need to be addressed, please let me know and I’ll fit them in.

Clearing up some confusion about cryptocurrencies, mining and when prices will go down.

I spend my last 6 months in a lot of cryptocurrency Reddits and informed myself about the topic. I read a lot of misinformation in the non crypto Reddits every day and because of that I am making this post to clear some things up and explain everything. Sorry for the wall of text, there will be a tldr; at the end
The Ethereum network pays out people who mine for them in Ethereum. The total daily amount of Ethereum giving out is more or less constant for now which means that if only a single person mines he gets everything, if a million person mine with the same hash power behind them everyone gets 1/1,000,000 of the reward, the reward itself does NOT increase, only the price of the ETH can increase.
Normally people would buy more GPUs until they reach a point of only a small profit compared to the energy costs and it would a reach a point of balance between total network hashrate and profit in USD (like it was in the last 3-4 years). The problem is that the price spiked multiple times way too fast and GPU manufacturing can't keep up which causes GPU prices to spike and delays this point of balance which results in MASSIVE profits for everyone who mines because the hashing power "supply" is capped. We are talking about 100$ a month with a SINGLE RX 480 right now (80$+ with power cost included).
Actually quite soon (yay). This is sadly a truth that not many miners know of (not to mention some are delusional... you will find them in the comments) and very few people think about. Even the popular Youtube channels have no idea about this. Before I come to the end of GPU mining first there are some numbers.
The current network hashrate is about 191TH/s and a total daily reward paid of 31,239,969$ in the last 24 hours. Because a single RX 480 gets about 28MH/s (pretty much average), we have about 6,821,428 GPUs mining ONLY Ethereum right now. If you every wondered how much money you need for a global GPU shortage the answer is about 30 million dollar daily.
Ok ok... the thing is the Ethereum network doesn't need your GPU power. It only uses it as a spam filter to make it harder to manipulate the network. You would need over 50% of the total hashrate to reliably fake transactions, think of it as a giant google captcha. You can easily replace that captcha with another one and this is exactly what Ethereum does in the near future. Proof of stake means instead of wasting GPU power you just stake your Ethereum and the more of your Ethereum you invest the more voting rights and rewards you get. If you are caught trying to cheat your whole money gets confiscated and donated to everyone else depending on their voting rights. Full proof of stake will probably be implemented late 2018 but just to be fair it already got delayed multiple times so there is no clear 100% date for it yet.
This is where the misconception starts. There is actually a second point of balance in all of this. All cryptocurrencies will always divide all the hashing power between them until they all reach about the same profit (people always switch to what gives the most profit). It may seem like there are a lot of profitable cryptocurrencies to mine but that is actually an illusion. Many of the smaller coins would be unprofitable after a few thousand GPUs because their total $ reward giving out daily is pretty small. The thing is nobody mines something that gives less profit so they switch. To sum it up Ethereum is basically the minimum payment job and everyone who goes below that wont find anyone willing to do the job until they get more profitable than Ethereum.
Now what happens if 6.8 MILLION RX 480 are jobless after a single update? They will all start mining something else. The problem is Ethereum has a GIANT majority in hashrate and all other mineable cryptocurrencies combined can't be profitable after Ethereum switches even if their prices spike by 10x.
OH HELL YEAH IT IS THAT BAD! Every heard of Monero? It is the cryptocurrency that caused the RX Vega shortage. Any idea on how much daily rewards they give out? A giant 1,504,249$ in the last 24 hours. Yes that is 20.7 times less and we are talking about the second biggest mineable coin out there. As soon as Ethereum fires all the miners everything will collapse and profit will turn NEGATIVE for a while unless you have free power. Q4 2018 is the end of mining for probably ever. Because the Ethereum code is open source and everyone can use it there will most likely be more coins that follow proof of stake after that (there already are some that already have it) so mining will most likely never come back.
There are many benefits. It consumes A LOT less power, it is most likely faster and people who hodl Ethereum get more Ethereum for just having it. Free interest rate hype! But the most important thing about this is that miners control the currency and every update to it. Sadly they don't have the same interests as people who want the crypto to succeed and improve. For example Bitcoin's block size is kept at 1mb even though increasing it was always the plan since 2009. Why? It's very simple. You can only fit X amount of transactions in 1mb and if it gets more than that only people who pay more get their transactions in faster which means more fews are being paid to the miners. While they make a fortune the currency suffers with spikes to 50$ for a SINGLE transaction (currently it's 18$). If the power goes to the ones having the currency they are directly interested in the well being of the currency which is better for everyone.
We will get the biggest GPU mass sell off in the history of the technology itself. I wouldn't be surprised to find a RX 480 for 100$ in December. Miners already made the price of the GPU back multiple times, they don't care about the price if they get at least something. This will be a GREAT time for buying GPUs. It already happened once in 2013? when ASIC miners got introduced for Bitcoin mining and all R9 290(x) got dumped on the market because they went from awesome miners to completely useless overnight. This time will be much bigger though because of the sheer amount of GPUs used for mining.
AMD did ramp up production last time with the r9 290(x) and got completely rekt. They couldn't sell the GPUs anymore and the used r9 290(x) were way too cheap to compete with. This time they are smarter and they just make as much as they can without investing too much while basically selling everything they produce for almost a whole year. Nvidia is about the same right now, they are just making bank without risking much. If you ever wondered why the 1070ti exists, it is basically a mining only GPU. The 1080 is horrible for Ethereum mining because of GDDR5X timings but the 1070ti has the same GPU power with GDDR5 non x. They only made this for more profit when selling to miners.... yet no reviewer called them out for this to my knowledge.
GPU prices will crash hard and the used market will have laughable low prices. These GPUs actually run undervolted, underclocked and at a low temperature the whole time because the bottleneck is the memory speed which means they are in EXCELLENT condition. Maybe their BIOS got flashed for better memory timing but you can just switch to the second BIOS or flash it back to normals. These will the GREAT to buy. Note that r9 290(x) and 390(x) GPUs should be avoided because they have such an overkill memory setup that their GPU core is the bottleneck (-> overclocked, overvolted and run at 90c+).
Well they will have a problem. Nobody will buy a 1180 if they can get a GTX 1080 for 200$ compared to something like 600$. Especially if Nvidia releases the 1180 while mining is still a thing. I guess they will wait with the 1180 or release a 1280 shortly after mining died with a really competitive price (if AMD can't compete they will just compete with themself...). Just think of the GTX 970 which got released with a 299$ MSRP and got actually sold at that price!
This got way longer than expected... well I hope you learned something. Just comment if you want to correct something or have a question. Most of these are assumptions based on thinking so none of this has to happen but is in my opinion very likely to happen.
tldr; Because Ethereum has almost all of the GPU power behind it and will fire all the miners in around Q4 2018 with the switch to proof of stake there will be a huge excess of GPU power and prices will crash hard.
edit: if you only care about numbers and facts and want a better distinction between assumptions and facts read my other comment https://www.reddit.com/pcmasterrace/comments/7rqkmo/clearing_up_some_confusion_about_cryptocurrencies/dsyzg6b/

PSA: Look out for cheap, used GPUs, BTC is about to drop to 8k

Bitcoin is looking like it's going to drop to at least 8000 today. Skittish miners might start jumping ship.
Contrary to the usual idea of mining gpus, most are undervolted and kept at lower temps for longevity.
This isn't the end for cryptocurrency, but it might be a good time to find a newish, cheapish gpu. Good luck.
Edit: Yes, bitcoin is directly mined by ASICs, not gpus, but if miners are using a service like Nicehash to mine altcoins, they're getting paid in Bitcoin. So the drops are still a kick in the pants.

[USA-MN] [H] R9 Fury [W] Paypal, possible trades

Timestamp and damage
This card is damaged. One of the fan blades is missing on the rightmost fan, but it doesn't impact cooling performance at all. Slight vibration at fan speeds between 27% and 33%, I personally solve this by running the card at a constant 40% speed (1400 RPM) so that the noise is constant.
Other than that, the card is in good condition. ~7 months old, ran on stock speeds for most of its life. When I first got it, I did an overclock and ran it undervolted to see what it could do (1115 MHz / -36mV respectively for gaming stable), but I got tired of the noise and didn't want to apply the undervolt every time I started it up. Also Overwatch hates overclocking.
As a mining card, it gets upwards of 28MH/s using NiceHash on DaggerHashimoto. To my knowledge, that's about the same as a 480 / 580. Here is a screenshot of Nicehash with HWinfo64 open to prove that it's running at stock speeds.
As a gaming card, it works better at high resolution than high fps, but it worked perfectly on my 1080p 144Hz Freesync monitor. I could get some numbers for Battlefield, Overwatch, Titanfall 2, etc if requested.
I'm asking $320 / Best offer / Trades if you have one of these items (Paypal can be included for either side of the trade)
Edit: Blanked my Bitcoin address and added a picture of the damage
Edit 2: Sold local for $300

Getting into Mining, and looking for some advice.

I've been 'lurking' on the topic of cryptocurrency mining for a few years now, and have seen the rise of Bitcoin and other currencies. I now have some free capital and am looking to get into the mining/trading game myself.
So far, I've formulated a basic build on PCPartPicker. I'm planning to use the 4 GPU kit from gpuShack, with 4x Sapphire RX470 8GB Nitro+ cards. So far, the build is ~$1200 without a case- the hard maximum on my budget is $1500, and this should cover the cost of riser cards, etc. I am also planning to find a metal fabricator to make a case, or make one out of wood. Are there any mistakes I have made on this build, or any areas in which it could be improved? Is the RX470 a bad choice of video card? I am planning on re-flashing the BIOS and undervolting/overclocking these cards, and my research has shown that the RX470 is one of the most cost-effective cards on the market. The build is the main part I am concerned about. Are there any bad choices I have made in terms of the parts? In what areas can I improve my build to be the most cost effective?
I would like to mine primarily Ether, but I am mainly looking into getting the highest profitability possible, so platforms such as Nicehash or anything else that is better for profitability may be a better choice for me. The gpuShack kit comes with a copy of EthOS, so I will most likely use that unless Windows-based alternatives like Nicehash are better for profitability.
The only real constraint I have is my budget- $1500. I don't have to pay for electricity, so that is a non-issue for me. I am mainly just wanting to pick the brains of this community so that I can have some help in starting to mine (hopefully successfully!). Thank you in advance for reading my post.

Profit Switching vs Mining single coin (1080ti)

I'm posting this a bit early to get the SubReddit up and running
I'm running two 1080ti miners to compare the predicted income with the actual income. The first is using Profit Switching and the other is mining ZCash(ZEC) from a ZEC pool directly (from Flypool)
Card setup: For efficiency, I'm undervolting + overclocking my 1080ti cards ( 75% power, +175 CClock, -100 MClock, GPU at 65degC with fans at approx 70%)
Direct mining setup:
Rather than use EWBF I've told Awesome Miner to use DSTM. EWBF gives me approx 690-700 Sol/S whereas DSTM gives me 718-720 Sol/S so a worthwhile change IMO.
Profit Switching Setup:
After having problems with ZPool massively undercrediting the work my GPUs have been submitting I've resorted to only using Mining Hub Pool for Profit Switching in AwesomeMiner. Since the 1080ti is ideally suited to the Equihash algo I've told it to just use that (this covers currencies such as ZCash, ZClassic, ZenCash etc). I then tell MPH to auto convert the mined coins to ZCash(ZEC)
Results:
AwesomeMiner is calculating incomes of:
Profit Switching: £4.13/day (£125.39/month) ZCash from FlyPool : £3/day (£90.78)
So the 6 million bitcoin question is, how close are the actual results compared to predictions. Stay tuned.

About to drop around $2500. Would love some opinions on this rig.

Ive been reading and reading and studying for days on end now. I want to understand as much as i can before i drop thousands on a rig and start mining. My plan is to ride this out as long as possible. I have faith LTC will go substantially higher...not as high as bitcoin..but i feel it has huge potential. With that said...i will cash out when i get enough LTC to match my initial investment to pay myself back. This makes everything i mine after the fact nothing but profit (minus the electricity of course). Ill use that profit to build a second rig based on how this is going but that comes later. Also...im a PC builder and have been for 10 years now.
I will be using six R9 280x's. Preferably MSI but ASUS if i have to. I only want one motherboard so i will be buying six PCIe x1 to x16 POWERED risers. I am under the impression that x1 or x16 doesnt impact hashrate. Only gaming (which im obviously not doing). I have 4GB of DDR3 1333 laying around in my room so i dont need to buy that. I will be using Windows 8 since i hear the drivers for Windows net better hashrates. I am correct to assume i can use 6 cards with Windows right?
Now... i will be buying a 32GB SSD since they draw very low wattage and an Intel Celeron Dual Core Ivy Bridge processor that draws 55 watts.
Here is where i am really unsure. Can this be possible if all else above checks out...with two 1000watt PSU's? I plan to try and undervolt the gpu's a bit to save on power and heat. Is that enough or too much wattage? I figure id buy an Add2PSU and hook them both up for stability. The cards will draw anywhere from 1500-1800 watts with the rest of the system hopefully not drawing anymore than 150. Can this be done with a single PSU? DO i even really need the Add2PSU? Can i get away without using it? Or should i buy a 1250watt and a 1000 watt and have the 1000w power 3 cards with the 1250w powering the other 3 plus the rest of the system?
These are the parts:
(I understand the GPUs are out of stock. I am waiting a couple days otherwise i will buy from Tigerdirect. Bit more expensive but available.)
So what do you all think? Opinions? Suggestions? Am i crazy?lol

[US-WA][H] 11-GPUs, My 2-in-1 Mobile Mining Rig [W] BTC/BCC/USD/PayPal

I have this posted on Craigslist at the moment, though I would be willing to ship as long as you're willing to piece it all back together once it all arrives, and pay for shipping lol.
I'll add the link so anybody can see photos, but I'll just copy/paste the entire listing below as well.
https://seattle.craigslist.org/see/sys/d/selling-11-gpu-mining-rig/6370381005.html
I'm selling my pride and joy of the last 4-6 months of my life, sadly I can't keep it in my apartment another day and have to hear my girlfriend nag about how much time I'm spending mining any longer.
This is really two separate rigs that I have combined into a single entity (see pictures for details).

RIG #1

Motherboard: Gigabyte GA-X99-Phoenix SLI CPU: 6th Gen. Intel Core i7-6800K (6-Core/12-Thread) (15M L3 Cache | 3.60 GHz) RAM: Corsair Vengeance 8GB DDR4 2400 MHz (x2 for a total of 16GB) Heatsink: Cooler Master Hyper 212 EVO (w/2 Fans) PSU: Corsair HX1000 1000W 80 Plus Platinum Grade Fully Modular GPU #1: MSI GTX 1060 Armor 6gb GDDR5 GPU #2: MSI GTX 1060 Armor 6gb GDDR5 GPU #3: MSI GTX 1060 Gaming X 6gb GDDR5 GPU #4: MSI GTX 1060 Gaming X 6gb GDDR5 GPU #5: EVGA GTX 1060 6gb FTW (Tri-Fan) Risers: Explomos Multi-Powered USB 3.0 (VER 008S) <----Newest Model

HDD: 2.5" Laptop SATA 7200rpm 1.0 TB HDD w/Windows 10 Pro

RIG #2

Motherboard: Asrock H110 Pro BTC+ (x13 PCIe Slots) CPU: 7th Gen. Intel Celeron Dual Core @ 2.60 GHz RAM: Corsair Vengeance 8GB DDR4 2400 MHz (x1 for a total of 8GB) PSU: Corsair HX1000 1000W 80 Plus Platinum Grade Fully Modular GPU #1: MSI GTX 1060 OCV1 Mining Optimized 6GB GDDR5 GPU #2: MSI GTX 1060 OCV1 Mining Optimized 6GB GDDR5 GPU #3: MSI GTX 1060 OCV1 Mining Optimized 6GB GDDR5 GPU #4: EVGA GTX 1060 SC Gaming 6GB GDDR5 GPU #5: XFX RX 480 8GB RS Hard Swap Edition (Custom BIOS Mod for 29-31 MH/s + Undervolted for Lower Power Draw) GPU #6: Red Devil RX 480 8GB (Tri-Fan) (Custom BIOS Mod for 29-31 MH/s + Undervolted for Lower Power Draw) Risers: Explomos Multi-Powered USB 3.0 (VER 008S) <----Newest Model

HDD: Western Digital 7200rpm 500gb 2.5" Laptop SATA HDD w/Windows 10 Pro

The features that set this rig apart from most others is the fact that it is 100% portable and easy to move. Its compact design makes for an easy-to-manage mining experience, doubly so with the fact that the entire rig is on wheels! From RIG #1 to RIG #2 I have connected an Ethernet cable; doing this I am able to create a Bridged Network Adapter and effectively enable a constant internet connection to RIG #2 from RIG #1 without ever having to do anything more than simply power each device on. Of course, you'll have to have some way to give internet access to RIG #1 for this to work properly, though this should come as no problem considering RIG #1 has built-in Wi-Fi access, as well as a second Ethernet port on the motherboard.
If you're wondering how much effort you'll have to put in from the time you buy it and get home, I'll say that this rig takes absolutely ZERO effort to install. The entire rig is ran headless, with Teamviewer installed onto both rigs, so you don't have to have anything plug into it except for the x2 power cords from each PSU, and an Ethernet cord from your router into RIG #1. That's literally it. 3 plugs, then connect to each rig with Teamviewer from a separate device (there's an app for that).
This rig can literally mine anything you want, I have a multitude of mining software already available on the device, and custom made batch files in each folder so literally all it takes is for you to decide which coin you want to mine, then double click a single file and start raking in the coins!
Here are a few hashrates that you can expect to get if you choose to utilize all 11 GPUs to a single coin:
ETHEREUM (Ethash Algorithm) - 240 MH/s ZCASH (Equihash Algorithm) - 3300 sol/s NICEHASH (Auto Profit Switcher Software) - $20+/day in Bitcoin (which is over $7000 if you didn't know!)
I'd be happy to help you get everything squared away, and would honestly just like to see this thing go to somebody that will appreciate its glory. I spent a LOT of time building this rig, and I'm sad to have to see it go, but my girlfriend is constantly bitching about it and I'm beginning to procrastinate homework these days because of it, so sadly it is time to see it go...
I have about 90% of the original boxes that the hardware came in when I purchased it, and I've only had it up and running for about a month total, so there is massive life left to be enjoyed with this guy. With the way the crypto is going (or at least Bitcoin), it is a wise investment to get into it now while you still can ;)
SERIOUS BUYERS ONLY!!!!!
You may contact me either by email via this Craigslist listing, or by phone @ show contact info .
I will accept cash, PayPal (in-person ONLY), or Bitcoin/Ethereum and other Cryptocurrencies as form of payment.

Question about profit by hour, graph, and wrong cpu profit estimate, advanced guide

Hi everyone! 1) Is there a way to see profit by the hour? I can see payout last 24 hours, but that's influenced by pools payout, and doesn't show btc earnings by the hour. Is is possible to see it? Maybe a graph over time? I'd like to start playing with undervolting and track performance (with selfswitching miner) 2) I've seen graph mode on the website, but I haven't been able to find it in the program. Where is it? 3) I've benchmarked GPU and CPU and set those to profile. GPU earning estimates are reasonable, 1-2$/day, but "coins" tab for CPU miner says I could earn 7-9$/day mining bitcoin and other sha-256 coins. When I activate CPU miner it never switches to those, and obviously the profit estimate is wrong as I actually get 0.04$/day estimate when I run CPU miner, I guess the hash power input is wrong? 4) is there an advanced guide exploring tweaking options and adding not-included mining programs and coins and other features for improved results? (not about tweaking the gpu settings, just awesome miner free program)

[x-post from r/ltcmining] should i buy a 6870 for 80€?

I can get my hands on a SAPPHIRE AMD Radeon HD 6870 for about 80€. It says i would expect 300kh/s from it at around 150w or less if i manage to undervolt it. I haven't found much info since the card is old and it was only use back when gpu bitcoin mining was profitable. should i get it?

RX 480 big drop in hashrate - did I break something? (nicehash, daggerHashimoto)

I'm new to mining. For the past 3 days I have been mining Ether with Nicehash and DaggerHashimoto at the expected ~24MH/s, sometimes little bit less.
My reference RX 480 8 GB was running at a full (undervolted) capacity, with an 69C average temp and 71 peak, the fan at 30-50% speed.
12 hours ago, I've noticed that the average USD/day is at 30% of earnings. I've rebooted the PC, it went back to normal. After around 6 hours, a new terminal window suddenly appeared, it started mining X11Gost with some crazy (I think?) rate of $14,5/day. Right now, it's back to DaggerHashimoto with a steady hashrate of 15-16MH/s. Average clock speed is around 700MHz and the fan is staying at the minimal 1238 RPM.
So, my question? Did I break something? Or is it just the reality of the mining and the market? I checked and the relative prices of bitcoin and ether (coinbase wallet) are worse than last few days, but that's my first try at mining and at analyzing any kind of stock-like prices, so I have no clue if that is the reason.
From what I understand the hashrate shouldn't go down like that?
PS I have just noticed one thing. My fan is staying constant, but if I lower the temp limits, the frequency is going down. Lowering to 55C max/target, it goes to 300MHz and stays there. What the hell? Did my fan just give up after 3 days? I used to play GPU-intensive games for prolonged periods of time and it held up just fine. Also, during night, the cold air was enough for 69C with 2000RPM at 1260 Mhz or 1100 with -4% power limit.

[USA] [H] GA-990FXA-UD3 rev3 + Sempron 140+2GB DDR3, HD 5970, 5850, 5830, PCI-E Risers [W] Bitcoin

Hi. I didn't want to sell these items here, because there is something like ebay in Venezuela. But the almost-hyperinflation we're living means few people want or can afford to purchase things here (minimum wage is 12.5$ a month). I was the first owner of all items, unless mentioned otherwise.
Thanks to government price controls, shipping of things up to 2 kg is cheap, around 5$. Shipping (through DHL) is included with the prices. I will accept Bitcoin only. So, here it goes:
GA990FXA-UD3 rev3 + Sempron 140 + 2GB DDR3 RAM: The motherboard was used for a year in my main gaming PC, then I switched it to the same model but rev4 (arrived too late for mining). The CPU and RAM are almost new.
Price: 90$ OBO for MB only, 120$ OBO for MB+CPU+RAM

9 PCI-E 1x-1x risers: Some are powered (that was DIY), some aren't. I pulled these a year ago in working condition when I stopped GPU mining. You must buy all 9.
Price: 25$ OBO for all.
Imgur
Reference 5970s: Bought them here from ssateneth at bitcointalk.org a long time ago. Used for mining for more than a year, stock clocks and undervolted to cool down VRMs.
Price: 90$ OBO each
Imgur
Imgur
ASUS 5850 DirectCU: Bought on Amazon on 2011. Used for gaming and low-intensity mining. It is the card in the top of the pictures with both cards. Comes with original box and the accessories pictured.
Price: 55$ OBO
Imgur

Imgur
Sapphire 5830s: I don't know where I got these, because I had many cards like these. I may have bought them on OCN or Bitcointalk in 2012. Used for mining until mid-2014. Fans are repaired, a small hole was drilled to inject motor oil inside the fan, then I applied sealant to prevent leakages.
Price: 45$ OBO for the top card (original fan), 35$ OBO for bottom card with replaced fan.
Imgur
Sapphire 5830 WITH PCI-E 4x link: The card works fine otherwise, but on GPU-Z you can see the PCI-E links at 4x, not 16x. Probably the PCI-E slot got corroded? dirty?. I tried my best to fix it with no results.
Price: 35$ OBO
Imgur
MY REP: #bitcoin-otc Heatware OCN Bitcointalk
If you think prices are too high, just tell me. I didn't do an appraisal first as I should have.

Need help tweaking 7970s - stuck at 500-550 kh/s

I finally stopped being lazy and booted up my old 7970s that I used to mine Bitcoins. I am mining Tagcoins right now and I believe it will be up there along with LTC and BTC. It's only about a month old and is already at $1.7 and it's backed up by a multimillion dollar company. Read more here:
https://bitcointalk.org/index.php?topic=317408.0
Anyway a little history about these 7970s:
They were never overclocked.
They were always undervolted to 950 mv and memory underclocked to 100mhz
The temps were always below 70C with huge box fan blowing at them.
Current Settings for Scrypt Mining: undervolted to 1000 mv and stock settings for clock / mem at 925 mhz / 1375 mhz. These are Asus Reference cards (bought them at launch to mine BTC).
CGMiner Settings:
cd cgminer C:\Users\Bitcoin\Desktop\cgminer-3.7.2-windows\cgminer.exe --scrypt -o stratum+tcp://tagmining.com:3333 -u xxx.xxx-p password -o stratum+tcp://wk5.botpool.net:5933 -u xxx.xxx-p password -I 13 -g 2 -w 256 --thread-concurrency 8192 --shaders 2048 --temp-overheat 80 --gpu-engine 925 --gpu-memclock 1375
I am using the following drivers:
13.11 Beta Catalyst Drivers
2.9 SDK
CGMiner 3.7.2 (latest to support scrypt mining)
Computer Specs: i7 2600k 3.4Ghz Stock MSI Big Bang Marshall 3 8GB DDR3 RAM ASUS 7970 X 4 Reference Cards 1300W CoolerMaster Gold PSU 2TB HDD 7200RPM
Any help would be appreciated!

To that effect, Bitcoin miners are actually more likely to undervolt their GPUs than overclock them, if they even bother to do any modifications to their software setup at all. There’s less benefit for a six-GPU mining rig being overclocked than a single GPU in a gaming PC. Bitcoin miners are much more concerned with efficiency than screaming full control of mining program options (you choose your own options, pool and wallet) notifications about offline/online rigs in telegram (popular instant messenger) alerts: missing GPU in rig, too much reboots or too high temperature; creating and assigning rigs to "Group Config" with the same mining options Ethereum Mining On Windows 10. Tags: Mining , Ethereum , Crypto Currency , GPU The value of dedicated GPU is going beyond the needs of gaming, it is proven to fulfill the professional needs for Deep Learning researches.As it turns out the modern graphics cards are very good at achieving the framerate requirements for virtual-reality.
