I've made a mod for the c11 algo. I get 30MHASH @ 85% tdp and +80 on the core clock. (1080ti) I see an improvement on all models tested. (970,1060,1070,1070ti,1080ti)

here is a screenshot with 85% tdp and "production clocks"

gpu 0; 1080ti
gpu 1: 1070ti
gpu 2: 1060 3gb
gpu 3: 1070



My miner is faster on the gtx 1070, than ccminer 2.2.3 on the 1080
