The challenges I see is that, how to manage the 12 GPU's worked flawlessly, though I seen some users able to get this done and in Youtube, however this is a bit uneasy thing to do, depends on hardware do you have starting with motherboard, PSU, Risers, memory. one thing, we are in a GPU shortage right now, you will be lucky enough to get these GPU's in a fairly price.

I would suggest to try these for isolation, Trim down your GPU to 3 or 4 only if your board supports 4 PCI-e x16 then use this without any risers. use only 1 PSU, if your rig runs solid after this actions, then, probably the problem is in your Riser or PSU.

I'm curious why is it so?
Rig 1 (6 cards, 3 Gigabyte, 3 Asus)
80% tdp, +180gpu, - 500mem
STABLE for weeks (never crashed)
Rig 2 (7 cards, all Asus Phoenix)
76 TDP, +150gpu, -500mem
FREEZES every few days
Rig 2 still freezes while rig one has never had any issues.
The only difference is the motherboard, which again is the exact same manufacturer and it's just Z170 vs Z270 (MSI Z170/Z370 Gaming Pro Carbon).
Rig 2 also has a beefier and much better quality PSU (Seasonic Prime Platinum 1200W vs Corsair RMx 850W on Rig 1).
Is there anything I can do?
I'm mining Neoscrypt.
Your GPU cards are also different from rig 1 and 2, that's explains it, usually they have different types of mem clocks sweet spots, just play along with it, until you discover its stability for underclocking or overclocking. sometimes, a riser is also at fault, ensure those risers are reliable. |

22.645 Mh/s or 296.932 H/s
Im using claymore dual amd and nvida miner and get 22.645 Mh/s
when I use claymores AMD only miner I get 296.932 H/s
the algo is ethash
I will understand this will be an Ethash algo -> 22.645 Mh/s however, let me guess, this one is an Equihash -> 296.932 H/s based on the profitability calculator, ethash is a bit higher but not a big difference compared to Equihash profits |

Correction, that date is to Announce only the exact date of Reimbursement, so don't expect to be paid at 31st. I think that once lost, trust is a VERY hard thing to get back. Nicetrash will not see me ever again.
Yep, lets see if they will keep their word to return what is stolen. oh btw, I don't know if there's some connection with BTC price on these days..hmmmmmnnn.. I am just overthinking it  No, I do not think you are over thinking it at all. We deserve to know what happened and right now anyone's guess is as good as any other. Here is one thought, it could have been an inside job of one or more people who were preparing to close up and exit scam everyone. Remember this happened right as BTC was crossing the $10k barrier. In a short amount of time it reached close to $20,000 when the stolen BTC was moving around. Who is to say they didn't sell a lot of that BTC between $15,000 and $19,000. Now that the price has corrected down to $10,000 again, they could buy back all the stolen BTC they sold, keep the $5-9k per BTC profit for themselves and sometime in the future mysteriously be able to return all the missing BTC to the users. Why not keep it all might you ask? Think about it, it would be far less likely for users to press ahead with lawsuits as well as any possible criminal charges if users are made whole again. Nice analysis bro, I was just thinking on the partnerships of NH and coinbase, and some other whales out there holding large amount of BTC and able to control the price. but the scenarios like you said has very good point. |

Yes, however double check the wire quality on your molex and wire splitters, been using this setups with my few rx 480's. but Ideal and safest is one is to one setups for molex/sata risers. |

Hi Guys, I am new here and also new on the mining world. there is to much information to learn!
I am having issue, with my rig, I can't get more that 16 Mh/s on my GPUs, and i have not cloud what to do, I read the post here and see that each GPUs should be at least around 25Mh/s.
Mine setup is
4 XFX AMD R580 black edition with driver version 23.20
User the latest drivers from AMD. Adrenalin Edition 18.1.1 - http://support.amd.com/en-us/download/desktop?os=Windows%2010%20-%2064Make sure you go into the AMD settings tool and set your video cards to "compute" not "graphics"... Also mod the bios to unleashed its full hashing power, you may get 29+mh/s at least with it then properly set your Clocks according to your preferences. https://bitcointalk.org/index.php?topic=1954245.0 |

I'm having trouble finding the material used on the back of risers.
What's the black material which has one adhesive side? is it like 3M double sided tape or some special pvc electrical tape? I tried various google searches but unsuccessful.
I'm looking to use this with my motherboards, can you advise is this is safe?
Also happy to take other suggestions
As long as the material is non conductive this should be safe, I don't see any special material on the risers back, a typical foam glued and latter peel off due to GPU heat. |

Hey Guys,
My hash rate constantly fluctuates between my 3 AMD cards. I have 2-RX580's, 1-Vega 64, and 1-1080TI. The 1080TI is very stable and constant. Between the 3 AMD cards the hash rate constantly drops. I've tried uninstalling/reinstalling drivers. I'm currently running the Relive drivers. Switching to regular drivers does nothing. In GPU-Z the memory controller load drops sporadically goes from 100% to 0% for the 2 580's, and the GPU load on the Vega 64 drops from 100 to 0 as well. I thought maybe my 1000W PSU was the issue so I hooked up an additional 850W PSU, and still the same fluctuations. I'm using Claymore's Miner. Any help or advice is appreciated. Thanks.
Try to check these: - GPU hardware errors, install Hwinfo to check errors - Mem clocks and CoreClocks, you can adjust to designated clocks, if you haven't done thru Bios mod  |

hi first post here as I'm hitting a wall for the last couple of months and I don't seem to be going anywhere with my first rig build.
3 Corsair RX 650 PSUs
Asrock H110 Pro BTC+, flashed bios 1.20
Intel Cpu, 8 Gb RAM
multiple Rx 580 Hynyx, stock over powered risers
60 Gb SSD
Win 10 1709 with several optimizations here and there
Blockchain august drivers.
Even using a single card I can't seem to go above 630 H/s; when I try to scale out adding cards using the -di parameters I hit system crashes and I constantly need to lower the -h parameters until it's stable but meaningless.
For instance I can mine 3 KH/s with 5 cards at 600 each or 6 cards at 500 each. I managed to mine using 8 cards but with a ridiculous hashrate of 300 per card or the system gets unstable.
What am I missing here? pagefile is 20 Gb, I'm using the environment variables as descripted
For Isolation purpose, I would suggest to install or use a single card only without risers, exclude other peripherals for the meantime. then fireup miner. check your clocks, try CoreClock 1200, Mem clock 2000 if the problem is still the same, I would suggest to flash them to unleashed its full hashing power. https://bitcointalk.org/index.php?topic=1954245.0 |

When I change connector to another PCI slot, it allows me to log in, in the Device Manager I can see the card with a yellow triangle (no driver), and after 5 minutes, when the driver installs, I can see the blue screen again. I must presumed you are using risers on this setup, try to install the GPU unto PCI-e x16 slot directly without risers. If its working fine, you know already what's the culprit. |

coins at once? If so, what would be the best combinations to do this?
Kindly clarify what you want to achieve, basically, mixing NVDIA and AMD is a bit pain, so if you have the chance to separate them I would suggest you do it. however if you are asking if its possible to mine using both type of cards for different coins at time, Yes, this is possible, by running different miner instances and specify each GPU indexes. |

I had so many problems with risers. It literally took months for me to figure out that the risers were the cause of all my problems. They may work sometimes and then not others or atleast thats how mine were. I changed cards ordered new power supplies and mother boards, reinstalled windows many many times and finally bought new risers and boom....problems gone. I did have a few issues with drivers but new risers fixed 99 percent of the problems I had.
I have HWiNfo on but i wont see any errors, but my rig crashs! I had problems with the drivers and i was getting the blue error, i did uninstall and re-install and ive never had that error again, but my rig mines for some hours and then crashs. I got this errors the launch timed out and was terminated" and "Non-existant CUDA device #5 specified in -d option". Any tips in what they can be? You think can be risers? A simple trick is try not to use the risers, intall GPU's directly into your motherboard. if it runs solid for hours, then throw your risers. oh btw, you also have separate threads with your concern, I've replied them though, try to do what I've said. |

Try to do Isolations by installing the 2 1080ti's first. then fireup miners.
if its fine, the culprit is in your second PSU with 4 Strix, from there you can do troubleshooting.

Hi !
i dont know how to start mining altcoin and i want learn with my capital investment .
My budget minimum $5000 My budget maximum $10.000
with this budget what else i can get and how long estimate i will get ROI ?
i know there is a lot tutorial in GOOGLE . but i need legit answer from someone here with 2 ways communication . i don't want make a lot mistake with my this budget .
please give me your advice so i can compare from other and make decision.
thank you.
Choose the hardware for mining. ASICs https://shop.bitmain.com/main.htm?lang=enhttp://www.baikalminer.com/https://ibelink.co/https://shop.pinidea.io/GPU Search in newegg.com NVIDIAs- GTX1060, 1070, 1080, 1070ti, 1080ti AMD's - RX570, 580, Vegas these two are the most commonly used as of the moment. Are you a techy guy? at least you know how to assemble computer desktops in order to do a GPU mining, otherwise, your option is ASIC. for profitability check online calculators Whattomine.com Take note that the results are only base on today's difficulty, so by tomorrow or the next few months the profitability would be lower or higher, that's some of the risk you will consider. |

I have a fairly new 6 GPU rig. It's on a Asus Prime Z270-A MB and uses risers. The GPU's are all EVGA Kingpin 1080 Ti's.
The problem is really rather strange and I'm looking to see what others might suggest as a form of debugging.
I can launch any of the mining software under either windows or Linux and the miner will perform flawlessly. Even OC it up to 800+ h/s per card on equihash with no issues.
But it's when I go to stop the software that I have a problem. One of the cards, and it seems to be the same one every time. Will then lock up the computer with an IRQ pending request. I can see this under linux as a stuck process called IRQ/XXX-nvidia (the XXX is a 3 digit number). Once I unplug the card from the riser, that will clear and the system utilization will return to normal. Same thing happens under windows 10.
Again, this does NOT effect the function when the mining software is running, just after... but any time you stop the software, this will happen and if you don't want to risk some hardware damage by unplugging that card, you have to do a hard reset.
I've done all the obvious stuff. swapped risers, swapped slots, etc and the problem always follows the card. As an aside I have noticed that this card is always the lowest of the batch of 6 from a h/s standpoint.
Once I remove this card from the system, I never see this issue on 5 cards.
Any thoughts on what I should try before I attempt to get warranty replacement from EVGA?
Thanks in advance,
The problem is that the manufacturer wont admit that your card is faulty, I wonder what would you tell them to describe your problems? I'm pretty sure you wont tell them you are doing mining. back to GPU prob, Ensure that you have a pretty decent PSU to handle those monstrous power hunger cards. |

Hi everyone,
I am pretty new to mining, trying to mod my bios on the rig's cards.
If anyone could give me timing strap values from the 1500 line to the end, that would be highly appreciated.
I was checking a couple of forums but most people just copying the lines or copying random lines from an rx 580 bios.
Any advice?
Thanks,
AlexSandor
Are you already came across with these thread? https://bitcointalk.org/index.php?topic=1954245.0https://bitcointalk.org/index.php?topic=1882656.0there are straps mention there, go try them out. they are easy to follow |

tried unplugging those two gtx 1070's and using their power supply cables for the riser and the rx 570, and suddenly it works. I have no idea if it is the cables or what the hell the problem is, and it is driving me insane. try it vice versa, get the cables you use for the AMD and install it to GTX, if it doesn't work, you can throw the cables in trash bins. Lol, seriously its already faulty, if you're a techy guy you could check the wiring continuity with testers |

Is it possible to delay all mining until DAG generation completes? I have a GPU that's pretty touchy and if the mining starts before it's DAG is generated the GPU will never come up. This causes the app to restart and sometimes crash. I've used the serial options and tried to slow it down but that doesn't prevent the mining from starting before DAG generation on all cards. Just a thought.
Thanks!
see the documentation: -gser this setting can improve stability on multi-GPU systems if miner hangs during startup. It serializes GPUs initalization routines. Use "-gser 1" to serailize some of routines and "-gser 2" to serialize all routines. Using values higher than 2 allows you also to set custom delay between DAG generation on GPUs, for example, "-gser 5" means same as "-gser 2" and also adds 3sec delay between DAG generation (can be useful for buggy drivers and/or weak PSU). Default value is "0" (no serialization, fast initialization). i would recomment starting with -gser 3 to serialize it with 3 sec. delay. if that doesnt help you can also try it with -lidag 2, which sets the intensity lower when DAG creation Thanks for the response. I've already tried the queuing options for serializing the startup including 'gser' and 'lidag'. It's not that the card crashes during the DAG generation, but when mining starts before the DAG generation is completed. The 'gser' option works to serialize the start, but it doesn't stop mining from starting before DAG is complete. Any other thoughts? did you set your Virtual mem to at least 16GB, I was also thinking a hardware issue, are you using risers? if you could post your HW specs then its more appreciated. |
