Got a rig with 6x1080ti, mining ZEC

Was doing fine for about 2 weeks but now GPU4 stops:

Watchdog restarts the mining process but GPU4 doesn't recover.

Team viewer and miner freezes when I try to access the Guake terminal, but the rig is still accessible via SSH and seems like the RSS process also still works because the rig is not rebooted.

I already replaced raiser, didn't help.
I dropped OC down to ZERO both on GPU and Memory, didn't help.
I raised POWER from 180 to 230, no effect on stability.

Any ideas how to troubleshoot?

try lower power say 160

or pull the bad card run it on a tester mobo that runs troubled cards.

Your tester mobo needs to be able to run 2 or 3 cards not six

and if you don't have a tester mobo buy a cheap one like this

Found the problem, it was related to the PSU connector board:

All my rigs are dual PSU and all of them worked fine. Just this one started to act up after 2 weeks. I removed all cards from one of the PSUs and the rig crashed anyway, at that point it was clear to me it must have something to do with the PSU connector. I replaced it and it's been running now for 2-3 days.

Seems to me it's a common problem, looking at the recent posts of IAmNotAJeep.
