I'm using this OS for 2 weeks with a Vega 64 and I'm very happy with it.
But I have a strange behaviour.
My rig is very stable when I tweak only GPU core and memory.
It's also very stable (miner up from nearly 2 days before I had to reboot the rig) when I tweak the memory settings using amdmemtool command (I stop the miner, I use amdmemtoom command then I start the miner).
But when I tweak the memory settings using web OS page and apply it, miner / rig freeze.
And when I restart the rig, miner start to mine and then freeze (lost of display, lost of SSH connexion).
I think that the miner start to mine before all the settings (especially amdmemtool) are applyed.
Is it possible to modify this behaviour ? A script to modify ?
