I have a sai/power limiter but @70% TDP i do get 770 hashes, with both rigs (i3-8100 3,60Ghz/8G ram/Win10) 1x asus strix rig / 1 evga rig (2ftw3/4sc's). Sadly I get constant crashes of the miner, I do believe its problem after updating Win, because I've tried with all the last drivers, in both rigs and it's the same s**t. BTW those values do consume around 190/195W, so I believe there's room to get the 1.000 @ 100%
