try to set mem -502, core +200/220 pl 75...
That got me to 40~41 Mhs but PL 75% = 225W.
Lowest PL with nvidia-smi for a 1080Ti is 125W
Settled for 34Mh/s @ 130W PL
+145 CC
+1600 MC
Thanks everyone!
I might play around with automated optimization.
225W This is a lot and in the summer the video card will overheat if there is no good cooling.Usually the power limit is set in the range of 150-180 watts. 34Mh / s is for the GTX1080, you can slightly increase the power limit.
