I wrote a simple parsers for some firmware structures, this should help.
Archive contains parsers for data/code tables list and for all vram table.
It should works with all 2xx, 3xx and 4xx bioses.

All other structures you can find in AMDGPU driver sources:

P.S. Sorry for my english smile.gif

If you mod your bios driver won't load...so Flash this bios https://www.techpowerup.com/vgabios/185322/185322 Sapphire, Nitro+ OC, Radeon (TM) RX 480 Graphics, (1342 / 2000)

Using atiwinflash www.techpowerup.com/downloads/2728/atiflash-2-74

Thank you for your help, but is it ok to flash an unverified bios ??

And last you said "If you mod your bios driver won't load" with the one that you gave will everything work just fine ??

Thanks again biggrin.gif:D

https://www.techpowerup.com/vgabios/184368/sapphire-rx480-8192-160603 Is the reference 8gb card if you feel safer since you have the reference pcb. Both are probably fine, but yeah, I understand why you might be wary of "unverified" I see your point. Good luck.

nm you had the nitro. So yeah the other bios is correct. Just "unverified." I haven't heard if the nitro cards unlock. Anyone?
