Thanks for this. I've been playing with the power settings with a Sapphire RX Vega 64 Liquid Cooled and got 1990.7 H/s stable @ 0.875 VDDC. Couldn't get power draw at the wall because I need a kill-a-watt thing.

Highly doubt if it is stable.
One of my cards needs 910mV voltage (gpu-z) to run 1408/1100 stable, other can handle 900mV. If yours is stable - you are the silicon lottery winner ))
I assume you use the soft power tables to make your adjustments. Curious which P states you set for core. Just P6 and P7? All? Is it the same as OldComer's where he adjusts 4,5,6,7 to be nearly the same. How about for mem p states? Just the last one? OldComer doesn't appear to adjust voltages after reviewing his registry file. Just P4,5,6,7 and Mem clock. At least comparing the default soft pp for vega 64 with his.
