That actually is pretty good. V8 is much more power hungry.
Your power is 208 watts per Vega 56. My seven average 225 watts.
Can you provide what your Core P6/P7 frequency/mv are set to and the MEM_P3 frequency/mv is. Thanks
Here you go.

Thanks, I changed my settings to:
Min P6: 1352 MHz @ 880mv
Max P7: 1552 MHz @ 880mv
Min/Max M3: 930 MHz @ 875mv
The one problematic Vega 56 I still have to run at 985mv on the core.
Doing the above settings on the other six saved me 30 watts while adding 165 H/s.
I plan to do additional tweaks when I determine the above is stable long term.
