Hmm, I've been playing around with version 9.4.

Should my GPU (RX570 4GB) have poor ETH hashrate (19-22) and get better as I undervolt? That seems backwards. Normally you have to jack powerlimit or give +vcore to stabilize clockspeed under utilization. Is this expected behavior?

At stock, 1.00v vcore and 1246mhz core, 2000mhz mem @ 1500 straps: 24MH
At undervolted / underclocked, 0.806 vcore, 1100mhz core, 2000mhz mem @ 1500 straps: 29MH.

I've played around with the powerlimit settings, different undervolts at different pstates. I can't quite see the pattern as to why this miner performs better the more I reduce power.

Does anyone have an idea?
