@ All with Vega 56 with Hynix HBM2:

I read here, that the most V56 with Hynix having issues if the frequency is higher than 890Mhz.

I have one V56 Hynix running well @890/0915mV
A second V56 Hynix has issues with this settings and brings GPU errors

What voltages do you apply in Wattman/OverDriveNTool/Regmods???

Please let me know. THANKS

I am not certain if raising voltage will assist with higher core clock without throwing invalid shares, but what I did was merely reducing the mem clock until no error was thrown. If increasing voltage will allow the HBM memory to hash at expected hashrate I would have done so. But so far it doesn't seems to be the case (able to push to 930 mem clock, but no amount of voltage bump will fix the invalid calculation error).

Thanks! This helps a lot :-)
