Hi, I've been working on trying to obtain the elusive 44Mhash of ether mining at 150w power draw. Using the blockchain drivers, I can easily obtain 44Mhash. However, with the blockchain drivers no matter what I do, my power draw is significantly higher, about 200-250w per card.
I've tried using Wattman to put in a manual voltage of 800 on each card. I've lowered the power limit to -50%. I've lowered the GPU core clock to 850mhz. No matter what I do, on HWinfo I see a GPU core voltage VDDC of 1.356v. It never changes. I don't think I'm undervolting the GPU at all with the blockchain drivers.
I tried following the instructions posted by S1L3N7D3A7H without success. https://imgur.com/a/WseAy
How do I undervolt Vega 64 with the blockchain driver successfully?
