Trying on 398.11 and I have one of 6 GPU losing power about once every 7-8hrs.
Not the same one and doesn't happen on 2.2.5

Also w/ v1.3 the load time to take it to max hash is still about 30-40mins.
That's a long time to recover if the miner disconnects or resets.

What times are you guys seeing to get to top avg hash?
