I just took this screen now. I just added another 1070 today and now they like to be at 76 mh/s. You will find my settings and pl here (the screen).
They seem to be happy at around 90-95 watts. I have four of them total.
Edit: The fourth 1070, in my other rig does 76.31 mh/s at 85 watts. It’s an old FE blower type card.
