Using the blockchain drivers from Aug.23.
Registry undervolting. 905-905 gpu/hbm and 1408/1100 freq on gpu/hbm.

Reducing the memory speeds does nothing. Stak will hang again.

Now, anyone has stak-amd running well on similar hashrates or are you all using some other miner ?

How low are you bringing the memory speeds? 1100 seems high for a 56, and high to run XMR in general. I don't see much improvement over 950, and run mine at 920 getting about 1900h/s (edit - unflashed - I didnt see any benefit flashing to 64, either)

Flashing to 64 gives you 64 cores and 1100 memory speed. For me I cannot reach 1900 on stak-amd without flashing. Are you using stak-amd or something else ?
Are you undervolting ? What is your power usage?

Edit: do you mind posting your full config?

I also had a lot of problems with stak-amd... I'm using 8xVega64 and after a while with stak-amd one card goes to 0h/s and then the whole rig just shuts down. I switched yesterday to cast-xmr, it seems more stable and until now I had no crash/shut down. I also noticed if I'm connecting with teamviewer or opening some applications like GPU-Z, the cards are starting to mine with a lower hash rate same like the HBCC was deactivated.
