it's an idea, but as a workaround. I really want to have the hashrate just stable, with no tricks involved.
Once i'm done with the new CPU version i go back to this problem as top priority.
Hey JCE
I figured out a manual fix to get those rx 580 cards to hash at max speeds on Heavy and be stable, any time i see one that has lost the max speed, i pause/unpause 4 times each (8 button pushes) in quick succession and the card comes back to maximum speed. May be something like this can be coded into the miner?
Test it on RX 580 8G - miner launched 5+ hours. 1st Gpu runs at full speed, 2nd speed drops. Tried your method on 2nd GPU - speed didn't changes.
EDIT: Yes, sometimes it works... But not everytime...
