Hi,
Will give $50 worth of btc to anyone who can help me out. Assembled my 4 x 1070ti mining rig about 3 weeks ago has a 1200w corsair platinum psu, asus h270 plus mobo, 2 x 4g ddr4 ram, running windows 10
So my first problem is when i benchmark each singular gpu on its own i get good hashrates, about 460 m/hs on equihash. But when i run more then one gpu the hashrate of the others drops significantly. When i try run all 4 together i get like 720 m/hs which is trash for all 4 gpus. I have tried uninstalling and reinstalling the latest drivers for my gpus and a clean install of windows. Does anyone have any tips for this?
My second problem is with all 4 gpus running any mining software i use crashes after a few minutes of mining and just freezes my pc. I tried getting 4g more of ram to bump up my system to 8gb (improved overall stability but still get crashes). I really am stumped here and have no idea what to do with this one, have tried searching through forums but no solution has helped. Thought it was a nicehash issue, then started using nemosminer and mining pool hub. Still crashes and shit hashrates...
So, i think this may be an issue with faulty hardware. My 2 guesses are either my powersupply or my motherboard. I am guessing one of them cant support to provide enough power across the rig with more then 1 gpu. It cant be my gpus because when i plug each in separately and benchmark them they all give me good hashrates individually. Just not with more then 1 plugged in...
I have spent the past 3 weeks trying to solve this and its doing my head in, alot of lost revenue aswell so if any one has any ideas please let me know.
Thanks,
IMHO, sounds like a power issue to me. when gpu cards dont get enough power it will run slower. I see this a lot when I undervolt my cards. some cards respond better to undervolting and can clock at a higher speed, some just default to a lower speed because it doesnt get enough power. probably silicon variation. |

its getting less and less profitable as ETH prices crash. word of caution

BTC mining isnt really profitable anymore even with ASIC miners at present prices.
As prices crash, these hardware makers will probably sell less and less. It's all about supply and demand.

Way too expensive IMO, though if you're somewhere that is VERY VERY HOT and VERY humid they might make sense.
What coins would you mine with the 1080Ti ? Presently, I dont see how that card is being viable compared to other cards? |

im shocked there isnt more water cooled options. thinking of making 2 PCs with water cooled 1080tis, so 4 1080tis in their case, sitting in a corner nice and quite. I can put them in different places. its easier for a pc to sit in a corner and nobody notices it, If I go on vacation for 2 months, I feel my water cooled GPU will be ok in the heat. hell I dont even have to leave a fan running! What do you think? but I think the blower fans are like new tech, 1 fan does a better job in the case. but then I dont know how these blowers will work when its 90 degrees out. the price of a regular 2 or 3 fan 1080 ti is as much as a water cooled one, I never had water cooled anything but if I had the money all my GPUS would be water cooled https://www.youtube.com/watch?v=8s_je7-BIEcim still seeing how I can do this with 2 1080tis water cooled but I dont want anything to break, I dont see many people mining with water cooled so Im a little cautious about spending on water cooled gpus could I get 2 of these and put in case and not worry? They just have a fan I put them in and im golden? https://www.youtube.com/watch?v=4ugGv0kw8pQwith the water cooler solution, you will have one more thing to worry about.... what if the pumps fails or the pipes start leaking, then the rig gets taken out... also please note that these rigs produce a lot of heat even in the winter. 60-70C is about 50-60C higher than winter ambient temperature, so with a rig of 5-19 cards, a lot of hot air will be coming out thru the metal heatsinks. not really something you would want to put in your living habitat, whether its enclosed in a case or not. |

Hi all, i'm building a 6x1080ti rig for the first time and got some panic with all the sata risers stuff to be honest. I've been reading this post and like 1389349539 more but still can't think clearly what should I do, and that's why I ask for some help here, would appreciate it a lot. As i said, its 6x 1080 ti and I assume will be underpowering them to more or less between 150 and 180W. Got the corsair ax1600i ( http://www.corsair.com/en-eu/ax1600i-digital-atx-power-supply-1600-watt-fully-modular-psu-ww) and also my risers have only 6pin power connections. - Can i use each PSU PCIe connectors to 1GPU + 1 riser, using a split cable (i believe 8pin to 2x 6pin splitter)? Is that safe/capable of providing the gpu+riser the W they need? - Should i use 1 PCIe to 1 GPU and the other 2 PCIe for 3 risers each? - Any other better combination/s? - Not any of what i said...  Thank you very much in advance which 1080ti do you have? I thought they all have 2x8pin power connectors? |

How is it that everyone is using the term ROI so incorrectly? ROI = (Gain from investment - investment) / investment. The answer to that equation is not months, it's a percent. The time it takes to break even or recoup costs is not ROI.
ROI as "misused" in the cryptocoin mining industry is generally a time estimate to get enough payout in coin value to match the price of the hardware. DO keep in mind that most cryptocoin miners are not financial professionals or experts. It also tends to ignore the residual value of the underlying hardware - which in the case of ASIC miners wasn't a particularly bad choice as those often had very little value left by the time they have earned more than their own price, prior to the current 14/16 nm generation, Out of curiosity, how much is an RX580 expected to fetch on ebay in 2020 ? Would like to be able to get some money back eventually. |

well I just installed a rx 580 inside the same case as my 1070. The 1070 is a blower style fan that keeps cool at its overclocked speed
the rx580 dual fan by asus gets HOT its running at 76 C while my MSI aero 1070 runs at 65 C
the rx runs to hot, I can see why BOTH amd and nvidia are now putting in blower fans while the cheap after market gtx are using a cooling system that makes the entire PC hot
its this hot and its in middle of winter, I am seriously considering selling both 1070 and rx 580 and just getting 2 water cooled 1080tis and be done with it,
no more fans, no more fans breaking, no more worrying about the heat in the summer.
at this rate in the summer the rx 580 will die it just runs to hot
IMHO, the open-style fans are fine as long as you have an open frame mining rig and run an external fan perpendicular to it. The 10-14 inch fan adds an additional ~50W to energy cost but they work well to force hot air out thru the spacing between graphics cards where hot air gets trapped. Ive noticed that even tho open-style fans have heatsinks that are designed to force hot air out thru either the back or front end of graphics cards, when you have 5-19 cards stacked in parallel the temperature kinda get a little bit higher going from the first to the last in the fan direction. |

Hi folks,
Anybody got some tips on how to dissipate heat from mining rigs?
the cards are reporting about 55-60C but it warms up the space quite well.
Normal room temp is about 10-20C over here.
Goes up to about 23-25C.
Thinking Im doing something wrong. Been running a fan at the rigs 24/7 but heat seems to get trapped in the room.
Saw some youtubers with air flowing thru across the room. No AC.
How do you guys deal with heat issues?
Is it necessary to run an AC when the temps go up to 20-30C ?
Thanks in advance, folks!
you should calculate you room sq³ and than get an air exhaust fan according to your room also left some window maybe for air to flow in, it will do the job Where would you stick the exhaust fan? unfortunately the room isnt arranged for this type of config. Is anyone doing this in a custom built backyard shaft? That seems like an ideal solution to me.... custom shaft with just enough sqft to house the rigs, with intake and exhaust fans... but would take much more work than Im presently accustomed to.... |

I haven't found a single place to find all the issues that bad risers can cause. I'm pretty new to mining and so far have found a number of them.
Here are the issues that I've run into so far:
-GPU not even being recognized (Initially I thought this was motherboard BIOS problem)
-GPU going to code 43 often
-GPU causing more than normal black screen flashes
And the most annoying so far:
-GPU to cause errors in HWinfo
I kept underclocking and adding voltage, but the errors would just continue. At first, I didn't think this could be a riser related issue, but after I changed out the riser, the GPU errors went away and I was able to clock it back up to where I thought it would be. One week of frustration; SOLVED.
Anyone else see any other issues with their risers?
Edit: Forgot to add one. Problems with reported hash rate vs effective hash rate in pool mining.
Moral of the story is, test your risers!
I got the same issue that I couldnt seem to resolve, so I disabled PCIE advance options. My mobo/PCIe was giving a lot of PCIe correction warnings (picked up by HWINFO64 as PCIe errors). The logs shows PCIe error correction. Couldnt pinpoint the riser that gave these problems. Seems to be random. Some riser boards would be error-less, but some combination would register those errors. So I gave up and disabled pcie advanced options which seems to include those error correction warning reports. Would be happy if anyone has a better solution? |

In my humble opinion, 10 month ROI isnt really that good if you consider that the equipments are on very fast depreciation schedule.
The ROI isnt as persistent as other types of investments, primary because mining causes standard computer parts to fail prematurely.
My X79 still runs fine after 8 years of service becase I only do web browsing with it, but...
The video cards in a mining rig may die in 1-2 years or less due to heavy cryptomining and/or faulty riser boards. tbh, I'm having some doubts about getting into mining.... jumped in when ROI was about 6 months.
If you manage to kill a GPU in less than 5 years of mining on it, you're doing it WRONG. I have quite a few cards that have been mining (or running the DNet client, which is also crypto work and JUST as intensive to the GPU) since the LITECOIN GPU mining days in 2013/2014 that are STILL mining away today. Do quit spreading the "mining kills cards fast" FUD lies. 5 years is quite impressive. Would you share some tips? Im getting into a bit of issue. My gpu's quality seem to be quite different from each other, despite all being from the same maker and batch. Some would clock at a higher freq given the same voltage some would be a bit lower. Any tips on modding or controlling a rig with gpu's all clocked differently? |

Hi all,
Instead of Afterburner, I tried to change voltage by adding -cvddc 900 to claymore command, but my GPU is not responding to it.... in fact the GPU remain idle while claymore is running with -cvddc and it was producint 0 MH/s.
RX580 card was bios modded with polaris one click option.
any idea whats wrong? is -cvddc not supposed to work with RX580s?
Which driver are you using? It is better to try to change the voltage OverdriveNTool https://forums.guru3d.com/threads/overdriventool-tool-for-amd-gpus.416116/I'm using the latest amd blockchain drivers (beta)... |

No it wont at 75C but it makes me uncomfortable seeing the temps that high. If you get close to 80c you will start wearing down the life of your cards. Can you space the cards out more, move them to an open air setup, or find a way to push cool air or pull the hot air away from the cards?
If not maybe ramp up your fan curve to 75-85% to see if that helps.
ill make more space between the GPUz so i tried to bios mod them after i finish claymore keep on telling me no amd cards were found and i cant do anything in afterburner can you hep me with that did i do somehting wrong while moding i mean i just copied the straps that i guess everybody is doing and working fine with them !! but apparently not me will try to help a bit.. there is no definite answer, it can be a combination of things, give the following a try if you want but no definite answer to your question... 1. run DDU to uninstall all other video drivers, and then install AMD blockchain drivers 2. go into BIOS and change your PCIe slots to Gen1 (or Gen2) mode. how to do this depends on the mobo and bios you have. 3. if you have a mining mobo, make sure mining mode is enabled 4. check your riser boards and usb cables, make sure they are plugged in firmly, if error persist then you should try another riser board/cable. i got a lot of faulty ones so this could be a main source of error, especially if you see pcie errors under HWINFO64 another thing is if you are modding the bios, run pixel patcher to patch it after you mod the bios, and always make a backup copy of the original bios in case you need to flash it back to factory settings. good luck.. |

Above 70C is not that bad but not that good either.
I guess 60-70C is the good temps, the lower the temps the better it is.
Anyway, add -cvddc 900 in claymore bat file and don't do MSI undervolting. You'll see better results.
I applied -cvddc 900 flag in my bat file but whenever I do that, the gpu remains idel and i got 0.000 MH/s.... what am I doing wrong? |

the fans on that card spinned up @60% speed when the card hit 72C.... I think the bios had the fan power profile at 20/40/60.. or something like that
..and i think at some temp its supposed to thermal throttle, but it hasnt done that yet...

btw, thanks to all those who responded.
I forgot to mention ambient temperature, its actually a pretty cold day around here, about 53F/12C ambient.
trying to decide if I should add an industrial type fan from a short distance or just a few 12cm system fans in front of the gpu rail? help me decide...!!

It will really depend on the configuration of your rig for the card that has a 72c temperature maybe some of your cards are close to each other, but 72c is not bad by any means as long as the card is not spiking up around 80c+ plus you ambient room temperature.
I tested them individually on the rack, it actually hit 72C all by itself. I tried reverting it back to stock BIOS and underclock both cpu/mem, and it was doing about 24MH/s at 64C. Not sure if its just silicon lottery or there is something I can tweak? Above 70C is not that bad but not that good either.
I guess 60-70C is the good temps, the lower the temps the better it is.
Anyway, add -cvddc 900 in claymore bat file and don't do MSI undervolting. You'll see better results.
thanks for the tip! will give it a try.. I tweaked most cards to 1000 mV (GPU) but there is one card that couldnt run stable at that voltage when overclock/one-click patched so I had to leave that one at stock voltage. Thats also the card that runs up in temp. |
