I just switched a rig over from ETC+XVG (blake2s) to ETC+SMART (keccak).
But my ETC hashrate on RX580s went from 31 mh/s down to 11 mh/s with keccak as 2nd coin.
Obviously this isn't going to work for me.
Anyone else seeing this with keccak as 2nd coin?
Try dcri of 6
7 will get you a bit more keccak but more heat and instability
Play with it. Don't be afraid to have the "hotter" GPUs at 6 and the cooler more stable ones at 7
