Working great with my vega 64/56 reference card ! Around 2200h/s avg..
But summer is coming , is there a way to decrease consumption with this this tool !
For now my card are running at 1407/1100 or 1407/950 at 875mV for most of them and 900-930 mV for bad ones.
Here are my own PPT and the overdriventool settings-->

If it's not stable, try a litte bit higher voltage in OverdriveNTool --> GPU P7 850mV / HBM P3 860mV --> 0.8375V GPU
My worst 2 GPU-s need GPU P7 850mV/ HBM P3 880mV --> 0.850V GPU
