just registered and want to say thanks, it's very good speed at 6x 1080ti rig for the lyra2z. average speed about 22.3 MH/s (x32 version/  i 21)
GPU setting pw 65% core +91 mem -502 . total power :930w according the power meter.

with same setting have tested ccminer 2.2.5 and coolminer 1.4
result as below:

ccminer 2.2.5 : speed 19.7MH/s ,power 945w
coominer 1.4 : speed 21.7MH/s(with 1%dev fee),power 980w

So this miner was the fastest lyra2z speed with the lowest power consumed and be claimed free.

great thanks if it's real free at this bearfish and dark marketing time

hope you guys could tested and compare your result.

thanks
