Turning a RX580 2048SP into a RX570 for MacOS support

[ZebyWebby]

Bios seems to be based for a XFX card since the configuration header is XFX_POLARIS20_D00034_XL_GDDR5_8GB\config.h
But boot string is conflicting: D00033 580S A1 GDDR5 256Mx32 8GB 300e/300m

The following bioses have boot string D00034 with Samsung K4G80325FB support

i did a bit of some testing and the first one worked at least for now it has. I haven't seen it crash or do artifacting yet and i only did a stress test for 2 minutes. However drivers work both on sonoma and windows . I did try the 2nd and third one you sent and the 2nd one worked but with driver code 43 and the third one didnt even work at all and just didnt give me a display. the fourth one i havent tried since first one seems to be doing its job.

All the E353 bioses with Samsung K4G80325FC are not validated by a staff member so it could be modified...

Can you try the following bioses with K4G80325FC support?

Thanks for your help, it's much appreciated. Unfortunately, my RX590GME graphics card broke, (while I was testing the new VBiOS). So, no way to test it, unfortunately.Thanks again for your help.

Hello.
What do you mean "broke" ?
You mean physically ? At a hardware level ?
Or it was "bricked" during the flashing procedure?

Yes, I guess it might be physical hardware damage. After entering the system through the graphics card in the second PCIE slot, I found that the RX590GME graphics card in the first PCIE slot could not be recognized. I tried many times, but the result was still the same. After removing the graphics card, I used a voltmeter to measure the GPU core circuit, and the result showed a short circuit. It may be that the graphics card was damaged due to frequent start-stop cycles (my guess).

Well, i doubt that a card enters in short circuit just like that.
But who knows?
On the other hand i would suggest to take a look on the "unbricking" procedure:

Hi people! I just buy a rx580 2048sp (I didn't know that was 2048 until I test it). Before that I have Ventura running in ryzen 3 3200g with Vega 8, with NootedRed. I made the vbios patch and ventura bootup with whatevergreen but no acceleration and the control center has disappeared. In windows I had to put the clock patch and reinstall drivers but is usable. What is probably what I'm doing wrong? I attach both rom, the original and the one i use to patch the vbios. Right now I put the original vbios to use windows normally.

The bios which you modified is not original anyway since it is running outside of RX580 2048 specs.

Flash this bios instead:
