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.
