Hi guys, I need a little advice
I flashed my Vega 56 to 64 and applied the 1050hbm reg file.
I tried changing the GPU core and voltage in overdrive.
I cant find any config that keeps it stable. My mem is stable but I cant get the core to stabilize.
My most stable was 1480/980mv for core and 1080/900mv for hbm.

There are 2 indicators that make me believe that my gpu is not stable.
1. The lights near the 8 pins are flashing every few seconds.
2. In GPUz at sensor page when you look at the core clock graph it keeps fluctuating.

At every fluctuation Hashrate instantly drops to 1400-1600 and comes back to 1800+

It seems that I need to mod the SOC clock to be higher than 1107 but I cant seem to mod the reg files.

I have the same issue with one of my vegas too

Fixed it by using xmr-stak-amd
Vega 56 flashed to 64 @160w 50C
2016/1800
I get 1990h with 1408/920 core 1150/900 mem 1999 soc

Running rock solid for the past 4hrs

which driver did you use? blockchain driver?
