Question BIOS file for Asus Dual Radeon OC RX 6600 XT 8GB (Micron memory chip) ?

If I remember correctly, Micron and Samsung are compatible with the same BIOS. However, flashing the BIOS voids your warranty and you are the one responsible. There are ways to force the flash even if it fails and so-called "bricks" the card. However, you will need a compatible BIOS nonetheless. Nothing is gauranteed.
