I have been mining ZEN for the last 2 months with my 6x1080ti asus strix (asrock btc h81, 2xEvga 1000w g3), and 10 days ago it started crashing all the time, even the whole machine started restarting. I checked cables and changed all risers and still the sam. Then I took one card I suspected might be the cause of problems and put it on my desktop machine so I could check it solo. It worked perfectly for 3 days and the rest of the rig with 5 cards worked perfectly so I thought it might be that one of the PSU is having problems with supplying 3 cards. I cleaned all the components with air compressor and put the 6th card back and now everything is working perfectly for the last 5 days...
So...we should regularly clean our 1080ti's :-)
Can u please tell me how much power u get on power meter with all 6 cards running and do you have any power limit applied?
Did u noticed any temps rising or/and rpm rising on GPU vents before the crash.
What temps are your cards giving after few hours of work.
Thanks
I set power limit to 90% and core clock +120, mem clock +450 and I get about 740sols per card with about 1700w from the wall with 6 cards running at about 55'c fan at 50% in the relatively cool and big room.
