I'm selling my Gtx 1060s because they are not very good at mining. Whether it was the Hynix memory, or the bad components used, I only got  17Mh/s out of each card after OCing without touching the voltage. I cut my fingers twice with the fan blades, and whenever the network difficulty changes some of the cards hashrates drops to 1Mhs. I'm getting 22 Mhs from 570 8Gb and want to know how to increase hashrate other than increasing the memory clock, thanks.
