Personally, I've got 19 mh/s on 1070, 21 mh/s on 1070ti and 32mh/s on 1080ti, but on 75-80% power limit and with spmod2 version of ccminer.
I'm not getting anywhere near 19 mh/s on my 1070s, at 75-80% power and +100 on the core mine average about 14-15 mh/s.
What am I doing wrong?
Try using the KlausT version. I used version 8.18 and it worked well. It is faster on other algos also.
