How to create 512Kb backup of GPU Bios?

[shadowhlohavec]

Hi, I'm trying to create backup of my bios , Msi rx 480 gaming 4Gb

- Gpuz created only 256kb
- atiflash didn't recognize the card
- atiflash cmd - no adapter found error
- atitool - didn't recognize card (driver problem) - driver update - didn't help
- radeon bios editor - card not recognized


Is there any other program or way how to do it? I don't want to risk flashing gpu and then trying to use 256kb backup which doesn't have to work...
Is there any other biosmodder which use the 256kb version of bios?

Thanks

Are you using the latest version of Atiwinflash? Make sure you're not using the one from 2013.

256kb is normal, polaris bios editor warns it should be 512kb but it's a false warning.

Run as administrator.. I wouldn't advise using 256kb bios file, it needs to be 512kb.

size doesn't matter, at all, i flashed different size, and cards are working, without any problems

thanks guys, the problem was in atiflash, I reinstalled it and it's working the backup was successfully created... Now I'm fighting with this stupid signature check

use atiflash and open cmd by admin then type
atiflash -s 0 backup470.rom
s = id gpu
