Hey. I noticed a strange thing while mining zcoin on miningpoolhub. For gtx 1070 pool displays hashrate closed to hashrate which ccminer displays: ccminer displays 1750kh/s, pool accepts 1600-1700kh/s. But for GTX 970 and GTX 1060 pool accepts only about 60% hashrate: ccminer displays 1100kh/s for GTX 970/1060 but miningpoolhub accept only about 700kh/s from each card. Could anybody explain what's wrong?
So i was forced to switch 970/1060 to equihash algo.
