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.
