The miner seems to be working great, better than any of the others I've tried so far.

3 x Rx580 = (1 x Sapphire + 2 x MSI) where one of the MSI is at 37Mh/s and the others lag behind.  I can't complained if I wanted to.  Hats off to the developer and I hope to get even better performance in the future.  It does appear the rate fluctuates a lot.   GPU Temp is about 8 to 5 degrees for selected point, which is fine.


No over clocking settings and using the following command:
mkxminer.exe --auto-fan --auto-gpu --temp-target 65 --asm -I 23 -o stratum+tcp://lyra2rev2.usa.nicehash.com:3347 -u %Wallet%.%Worker% -p x --exitsick --engine 1100 --memclock 2100 --vddc .975 --temp-target 55

PS: One request to be made, workout the proper fan speed to temp limit.  Seems a bit off for MSI 580's.
 Also please address the Dev fee, which we all want to know.
