Do I need to flash bios them with 64 bios ?
Is there any good specific timing for ETH on Vega 64 and 56 ?
Thanks
Definitely. Flash your Vega 56 with 64 air bios.
It'll help as it will increase the memory frequency of the card.
In 56 bios, I was able to hit 935 MHz but with 64 air bios flashed the memory frequency was stable at 1100MHz.
Any further and it was unstable.
