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.
Hope this helps

Yes it does, thank you.

ps. You are probably doing about 900W from one PSU and 800W from other, isn't that little to much heavy lifting for 2x 1000W PSU if you look at long term 24/7 mining?

Yes, about 900w and 800w, those are very good and durable Evga G3 PSU with 10 years warranty, and should easily manage that. For a while i used to mine at 106% Pw limit without any problem, but figured its not such a big gain...
