tpruvot's release seems to have lower rates poolside than in the miner window.
zcoin dev posted a public ccminer with fix for rates poolside problem
with this public ccminer (correct pool rates) :
1060 6gb (micron) (70% tdp): 1200 kH/s
1080ti 11gb (70% tdp): 3260 kH/s
will test on 70ti this week end ..
ya they posted that miner weeks ago ;p (its the one "kaylmist" has been trying to sell people lolz)
1070ti does 2300 kh/s, i own a few and have extensively tested
with my 1080ti's doing 3300 easy, i wont worry about this SP_mod unless a 1070ti does 2500-2700, no point for me otherwise.
