23-24Mhs on avg. is good, 30Mhs+ is at peak on fastest algorithms. Fot GTX1080Ti's I get 22-23Mhs avg. at 190Wt(also avg) + curve coreOC and mem -502 and for GTX1080 ~17Mhs on avg. at 145Wt + coreOC and stock mem. My core overclock is like this: 6.25mV step = +12.5Mhz(1 step up for coreclock in the curve), +12.5mV step = +25Mhz (2 steps up fore coreclock in curve), on starting cclock differs depending on card.
