what method are you guys using to have a fixed core clock ?
i set it up for let's say 1400mhz for vega56 using overdriventool but when watching it with HWiNFO is not the same it's about 1350Mhz
any hint appreciated
from yesterday I experience same problem with Vega 56 / 64 cards.
Have you tried disabling all lower p-states in OverdriveNTool, i.e. click the little text "P2", "P3" etc left of the MHz column so they are greyed out? Only using the highest state has helped me sometimes to force the driver to use the specified clocks.
