This does seem quite similar but this happens during normal mining and not during DAG generation so it is less likely to be a power issue. Still, could you try to lower the power limit of your cards and see if this fixes the problem? On our test rigs the PSUs are over-provisioned by at least 50-60% so we never see such problems. Even if the PSU(s) should be enough on theory, some GPUs have momentary peaks in their power consumption which can drop the voltage enough to cause a crash.
We will also investigate why the program doesn't restart as it should (and as it does in many other cases).
Hey, thanks.
I doubt it's a power problem in my case, this system pulls ~780W from the wall, and it's running split between 2 750W platinum HP server supplies. with the motherboard, 1080ti and 2x 1060's running off one PSU, and the other 6 1060's running off the second.
Z270P motherboard
G4400 CPU
4GB DDR4-2133
32GB page file
6x GTX 1060 6GB
1x GTX 1080ti
In any case, I reduced my power limit on the 1060's by 2% (from 70% to 68%)
and reduced the power limit on the 1080ti by 5% (from 80% to 75%)
didn't seem to affect the hashrates and dropped me to 765 from the wall so that's good.
I've also switched back to 2.8b for now. I think it's a problem in 2.8c causing this.
