So got a Vega 56 to play around finally.
Mining cryptonight @1926 H/s with xmr-stak at 1408 core and 925 HBM2 (900mV). Even though the overdriveNTool profile is set to run at 1408/915mV HWinfo64 says the CVDDC is at 1.25V. MVDDC changes get reflected but not the core. Any pointers?
I am already using soft pp table btw.

Core P6 is 1212, 910 mV and P7 is 1408, 915 mV
HBM2 P3 is 925, 900mV

Pretty impressive, is that a reference model with Samsung memory?
The readings on hwinfo could be flipped depending on version reading, 1.25V is actually the MVDDC, your core voltage should be sub 0.9 as for your p7 915mV.

May I know what's your xmr-stak config for this? Inn terms of intensity.

Reference with Samsung. 1932 intensity, 2 threads. I am not sure if it's flipped. Cause it reflects the changes I do in MVDDC in HWInfo.

Samsung is indeed still the king, I am more amazed with the intensity with you not flashing to 64 BIOS.

It is indeed flipped, p3 mem voltage has nothing to do with adjusting memory voltage, it's hardcoded to 1.25V in BIOS for 56, and 1.35V in BIOS for 64. The adjustment you make in p3_mem voltage is merely setting the bare floor voltage for GPU core, but p7_gpu voltage takes precedence; no voltage adjustment that you can perform in OverDriveNTool is going to impact mem voltage.
