First I connected the vega 56@64, installed the driver, then replaced it with 64, I think it's somehow related. After rebooting hashrate drops to 2000 and that would get 2500 I need to remove the driver, insert the vega 56 and so on

I cannot reproduce ... I swaped rizer cables between my flashed vega56=>vega64aio and native vega64aio. Speed stays the same, 2k for v56 and 2.07k for v64
I do not understand how this works. It looks like a combination of magic and drivers.
Sometimes its the sequence of the clocks and reduced voltage and power limit that allows it to go more stable then normal.  I find if I suddenly switch from low clocks to a completely different setup its more likely to crash, this might be because of SOC clock not allowing the higher memory.  I sometimes notice SOC has come way down below 1100 so even if I increase voltage to try higher memory speeds it doesnt like it as SOC is a limit generally.   It might require to have intermediary profiles to gradually raise the clock before it can be left stable.

Also turn off all windows graphical effects if you havent, leave it on high performance.  an open web page is not a good idea also
