Highly doubt if it is stable.
One of my cards needs 910mV voltage (gpu-z) to run 1408/1100 stable, other can handle 900mV. If yours is stable - you are the silicon lottery winner ))

It still running in the same session and I don't see any speed fluctuations, it seems stable. As a matter of fact the pool is reflecting my hashrate very well too. Try lowering the HBM voltage to the same voltage as Vega 56 version. I think this is what did the trick.

Well, I tried and it seems to work ... miracle ))

BTW, I was able to compile dev-branch of xmr-stak-amd on windows ... they have one-letter bug in config that makes an error ... but I found it ))

Nice rednoW! Glad you got it working.

I made this little cheat sheet to help me tweaking the .reg file, going to publish below to possibly help other people. Below are the settings I'm using to achieve 1990 H/s @ 0.875. Custom values are highlighted in square brackets.
What are xmr-stak-amd's dev-branch improvements over the current released one, do you know?

DonBit, great work. Can you please find some time and post a step-by-step tutorial of your specific settings? I think I seem to be missing something because I am almost there, but not quite. Thanks!
