Here're some good (or even best, as for me) settings for ccminer-2.2:
GTX 1080ti => -i 23.5 => 35.9 MH/s
GTX 1050 => -i 21.4 => 6280 kH/s
These ones were selected as the best ones. Tried -i setting from 18 to 24 using 0.1 step.
My 1050ti's are getting ~7.3 MH without messing with the intensity. I'll post back when I mess with the intensity. Aw boo, didn't realize the intensity was pre set in ccminer. Bumped it to 21 and I'm getting ~29 for 4 1050ti's ATM.
