is it crashing when it runs DEV FEE for Claymore? re-loading the DAG?
I had same issue and I think i have it working, will know later today, so far no crash on Pirl.
I have not had a crash yet. But in once instance, after mining the DEV Fee, I had a serious drop in hash rate across all GPUs (RX470, RX480, 2 x GTX 1050ti).
And it only happened once thus far.
I have also noticed the fan speed is reported as 0 once in a while, then Polly restarts the rig, although it was quite unneccesary. When I used multi pool miner some time ago, the API also reported zero fan speeds at random intervals.
Finally, stale shares are ranging from 4% to 15%. But overall hash rate increase seems to outweigh this by about 0.0001 ETH per day.
