Hey guys, there seem to be a lot of people here and elsewhere that managed to get the Vega 56 to a smooth 39MH/s- ish performance at very efficient power draw numbers.
If reports are true, some of which must be running at 150W draw, which I find impressive.

I am currently running into huge problems, especially with AMD Wattman which feels like not correctly applying my settings done (especially on voltage).

I did this:

- flashed Vega 64 bios on one of my my Vega 56.
- Windows: Clean install
- Installation of latest blockchain drivers + AMD Wattman

Running Claymore Miner, just on a stock Vega 56 and a Vega 56 w/ V64 BIOS.

I start miner, get 37 MH/s. However 300W+ from the wall for one card.

- Decrease voltage: No change in Power draw
- Set P6 / P7 states to max core clock: 1000 (first, gets applied)
- Set Memory to 1100MHz clock, resp 950MHz for the V56 (gets applied)
- Decrease power limit to less than -10% -> Memory jumps back to earlier state, which however I am not able to adjust
- Even then, GPU clock starts ticking off at about 1500 again.

So it seems to me that some of the settings are being overridden.
Max I could get was 40MH/s but at almost 400W, nowhere close to reports of 39 MH/s at 150W

Anyone else experiencing fluctuating core / mem clocks or non applied voltage settings?

Thanks and cheers,
