DISCLAIMER!!!

This procedure involves risks for your GPU, I do not take any responsibility for it, I will limit myself only to describing. It is recommended to run this in GPU with dual bios.

The mod in question and the relative Vbios is specific for the Sapphire Nitro+ RX 470 4g with elpida memories.

GUIDE:

Run windows and download this program: GPU-Z by techpowerup and ATIFlash

after the download, look at the manufacturer of the memories; these can be elpida, micron, samsung or hynix, so as to download the most suitable V-Bios RX570 for your card for conversion.

When you are sure, download the suitable V-Bios, in my specific case this: VBios

Unzip ATIFlash and copy the previously downloaded vbios into it. At this point open the terminal as system administrator and go to the root of the ATIFlash folder and run the command:

amdvbflashWin -f -p 0 nomerom.rom
