Hi Guys.
I am really desperate. Ive been trying to set up my mining rig for 7days + now and i just can't get it stable, no matter what i try.
Hard ware:
- 6x rx580 8gb red devil hynix memory
tried anoraknophobias bios & frosty s bios
- 1x rx580 8gb red devil samsung memory
anoraknophobia bios
- msi z170a gaming pro carbon motherboard:
newest bios
above 4g encoding enabled
pice max link speed gen2
pice latency auto
display output by integrated graphics by default
windows whql enabled
- 60 gb ssd
- Intel Celeron Processor G3900 (2,80 GHz, 2 MB Intel Smart-Cache)
- 8gb RAM
- 2x 800w be quiet PSU (one for mobo + 3 cards, other for 4 cards)
- windows 10 home version 1703, build 15066.786
- aug. 23rd blockchain drivers
- claymore miner version 10.0
- virtual memory 30400mb
i have tried claymore settings:
-1100 cvddc -1100mvddc -1100 cclock -2100 mclock
to
-850 cvddc -850 mvddc -1250 cclock -2250 mclock
and pretty much anything in between in claymore v10.0 and v10.5, within 10 minutes max i get the infamous "GPU X hangs in OpenCL call, exit.." Error on one card after the other.
whenever i start the miner without any clock and voltage settings, the cards also ramp up to 30mhs, but fail within 10 minutes, same OpenCL error.
I have tried to troubleshoot:
- temperature is not an issue, all temps stay within 50-70 °C
- power doesn't seem to be an issue, i have added another 600w PSU to power one card of each of the other PSUs, didn't help
- i have fiddled with the pcie max link speed settings(gen1, gen2)
- i have swapped all risers
- CPU is not getting to too hot, although under heavy load during DAG creation & weirdly sometimes when one card fails or when i exit the miner
- I have tried the method of adding one GPU, testing it with the miner, adding another and so forth:
inexpliccably, the rig seems to run fine with up to 3 GPUS, when i add a 4th GPU, the 3rd GPU starts failing. (not the newly added one).
- i have reinstalled windows several times
- tried to add claymore options -gser, -eres
The only thing i can think of is that maybe the CPU could be a bottleneck, since its under heavy load sometimes and can make the rig a bit slow for about 10 seconds. Still, the errors arise when the CPU is just sitting at 15ish %.
Another weird thing is that, whenever i let each card run individually, they all run fine with no issues for more than one hour. So i guess it cant be a riser issue.
But here comes the worst part:I have set up another rig with 7x rx580 sapphire nitro+ 8gb hynix (anorak bios), same motherboard, same CPU, same amount of RAM same driver, same virtual memory, same version of Windows, claymore v10.0 and it happily runs on 850cvddc 850mvddc 1250cclock 2250mclock churning out a little over 200mhs for the past 3 weeks without any problems.
Its driving me nuts, seriously
Please guys, if you have any idea what i could look for to get this baby stable it would be much appreciated.
