Ahh okay so your just hard setting voltage then pick and choose which frequency is running best and you have it set by default to 675. So we could just go in there and set it to 700 etc.

Do you know which voltage would be the highest the bitmain 1600w psu can use. I want to run my s9 at 1550-1600w to draw around the max the psu can handle and hash as fast as possible with that psu
