- Start date
Hi, it really works, I installed the bios after that I used the program ATI Pixel Clock Patcher. I didn't use GOP because I didn't find it for RX570 but it still works thanks to your work. Thank you very much @

With the current bios it will not work since MacOS does not support a RX 580 with 2048SP. Flashing to a RX570 will give you a bigger chance it will work.

Hello friend,
The bios I sent you already has GOP-1.67 updated (functional EFI)
I was very happy that it worked!
Thanks for the feedback!
Hello friend,
Follow modified bios for RX570 with GOP-1.67-Updated (Functional EFI)
Also included is the AMD-ATI Pixel Clock Patcher application to validate your card driver with the new bios.
Please try it and let me know if it works!
I await your return.

IT works on Hackintosh full hardware acceleration with 2 monitors both HDMI DP working THANK YOU very much for your help and support!!!!!!Hi, yes, (although my graphics card is a Sapphire RX 590 GME), I tried changing the 6FDF in the Device ID to 67DF. The result is: it can be correctly recognized and driven in Windows systems. How is this achieved? You can use WinHex software to change the 16-bit values in three places in the original BIOS file. (DF 6F changed to DF 67). But I encountered a problem: neither the original vBIOS nor the modified vBIOS can display the motherboard brand logo when booting only through UEFI (meaning that the screen is black after pressing the startup button until entering the Windows system desktop) .Attached is the original BIOS file

Why not flash a regulair Sapphire RX 580 bios which is based on the same board? I am aware it is a little bit slower but then you dont need to edit the bios.
Compatible bios with Hynix H5GC8H24AJR and Samsung K4G80325FB support

Thank you for your help. Sapphire RX 590 GME, its interface is 2x HDMI 2.0b and 2x DisplayPort 1.4a, no DVI. I tried flashing the VBIOS of a Sapphire RX 580 compatible with Samsung K4G80325FC. However, it seems that it is not stable enough. After DDU uninstalls and reinstalls the AMD driver, the black screen appears when running 3DMark TimeSpy, the fan speed is very high, and the noise is loud. Moreover, when CSM is turned off (that is, UEFI Boot only) and the power button is pressed, the monitor remains black until entering the system desktop. I learned from GOOGLE that this phenomenon is caused by the imperfect UEFI boot function of the AMD graphics card. Moreover, after trying to use the GOPup tool to update the GOP modularity, the problem is still not solved.Why not flash a regulair Sapphire RX 580 bios which is based on the same board?

By using WinHEX software to compare the BIOS of the original Sapphire RX 590 GME and the VBIOS of the Sapphire RX 580 of Samsung K4G80325FC, I found that the difference between the GOP modules of the two is only the Device Id. This confuses me. Is there any way to solve the problem of black screen before entering the desktop during UEFI boot?

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?
Hi @jocsmister. I have a Chinese RX 580 2048 graphics card. Thank you @VuurVOS, he helped me and I flashed it with a new bios and worked in win and macosx. But when I was in Windows 10 and sometimes MacOSX, the screen started to flicker in DP. I would appreciate it if you could fix this problem by editing the my original rom. Thanks a lot.

these have different memory supports. I don't know if any of them would work. I've also already tried modding my own bios to act like an RX 570 and a 580 but I didn't get a display. Also unfortunately I do not want to remove the cooler on the card because I don't wanna lose the warranty on it yet lol.Please make a screenshot of the PCB. Which bioses did you try? I think this one these bioses might work:
Edit: the first one worked what a surprised but for some reason im getting no signal booting into macOS but my faps lock still works so it didnt lock up.
Edit 2: The second showed no warning sign but for some reason hardware acceleration still doesn't work and my monitor is connected to "Microsoft Basic Display Adapter"
Edit 3: Nevermind it shows the yellow exclamation point as well and no signal booting into macOS

Anymore VBIOS to try out? I've tried the two and no I really do not want to open up the card and void my warranty.

Which warranty? You already void the warranty by flashing a different bios
Also Chinese cards have questionable warranty 
Did those bioses work normally in Windows?

The company wouldnt find out that I did since the seller doesnt check for BIOS changes unless i kept the 570 bios in there. Ive already RMAed the card once due to my old one having faulty vram (possibly heavily mined) And yes the bios does work partially on windows. Without drivers that is it shows up as an RX 570 Series but with error code 43 and no gpu acceleration windows. And on macOS it just shows no signal.Which warranty?

Do you need to use AMD/ATI Pixel Clock Patcher for installing the drivers under Windows?

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
