Help ATI Tools XFX RX 590

[Epaminombas]

I tried to change the BIOS of my XFX RX 590 to one of the PowerColor RX 590, using ATIflash 293 and give me an ID error trying through the GUI. When I open CMD the program closes when I try to execute any command from ATI Tools. Windows 10 1909. Is it a problem with the windows version?

GUI version is more easy to use. Command prompt version has more features in it.

But the GUI version is giving an ID error because it is 2 cards from different manufacturers. How to make ?

XFX Rx 590 not working on Mojave

I'll just add to this thread my experience. XFX Fatboy would cause my Mojave USB installer to fail. I used my Windows 10 boot to flash it to the PowerColor BIOS and Mojave installed and it works. There are difficulties in flashing the BIOS. The first thing is there are actually two of them on...

Look at the flashing instructions at the bottom of this post. Don't forget to take a backup.

Use Polaris bios editor, also editing the bios will break uefi and you need to patch using the gop patch updater if you can't see post using the modded bios

I tried the 2 methods. But without success. I already run both with an administrator. I've tried compatibility with windows 7/8 and nothing. When I update via the ATI Tools GUI for the ID error. When I try via CMD the program closes and I can't open it again because it seems to be in the background and then I need to restart Windows 10.

Will the GPU lose its UEFI?

if you modify the bios yes, but as I said you can patch it, what is it you're looking to gain from modding the bios?

I managed to transform my XFX into a PowerColor. My XFX has 2 BIOS, it has a key that I can still change in the key and go back to the XFX BIOS. Two BIOSs in one, all OK. I stressed the RX 590 on AIDA64 and played a game and everything worked. The only thing that bugged was the Edge Chromium, it is in black screen and I already uninstalled and installed it. So I installed Google Chrome myself.

Edge Chromium;

Probably 2D or low performance 3D clocks aren't good for your card.

I changed this XFX to this PowerColor. I looked closely at the type of memory, the clocks and the number of video outputs. They are very similar.
