Yesterday I did the memory strip edit on the bios of my Rx580 with the PolarisBiosEditor with one click patch, I made a back up bios beforehand, then I flashed the moded one with amdvbflash, it was a success, reset the PC, all worked well, I gamed all day, no problems, and in the morning when I turned on the PC the monitor stayed dark, the fans spin but that's it, I tried the 1 to 5 pin jumper wire on the bios chip, boot the system with the iGPU, tried to see if amdvbflash will detect it with "amdvbflash -i 1 ", "amdvbflash -i 0 " but the card is not found anywhere, it just spins its fans. The card is AXRX 580 8GBD5-3DHDV2/OC, I know it has dual bios, it has a switch, but that doesn't help at all, If you have any suggestions I'm well open, other than go and buy a new card that is
