RX580 2048SP - Need help flashing RX570 BIOS

[PracticalPear100]

Hi, I'd like to request for some help regarding flashing a MAXSUN RX580 2048SP 4GB. I bought it a couple of years ago thinking it was RX580 but I've researched and it's an RX570 with 10% improved performance. I would like to install Hackintosh but I have no idea how and what BIOS to flash to make it work.

Can someone kindly guide me?

First, Does your video card have DUAL BIOS support?

Second, read the guides and find the a correct BIOS from:

I don't have DUAL BIOS switch unfortunately.
I also checked that page, my GPU's bios are not listed.

I would not flash anything without DUAL BIOS unless you really know what you doing.

Also I am not sure why you want to flash your VBIOS in regards with MacOS. Both RX570 and RX580 are supported.

I don't have an RX580. I have an RX580 2048SP. It's a china-exclusive GPU that's 10% better than 570 but 10% worse than 580 in terms of performance.
I installed Mojave 2-3 years ago, back then the GPU refused to be detected because the GPU ID is neither of 580 nor of 570.
I read here that others were having the same problem

hi all, i make a mistake to buy Sapphire Rx 580 2048sp, which i thought its Rx 580. Of cause, mac os cannot native support this card. And i tried to use fake id(0x67DF), but i got black screen after clover. Rx 580 2048sp Device id is 0x6FDF. Do you guys have any ideas how to solve this? or i...

In the thread, they suggest using fake-id and I did that back then but it never worked. I was using clover bootloader.
Someone also wrote about hackintosh working after they flashed the bios from 570. This is why I wanted to do it.

I haven't tried hackintosh since then, do you think it can work without flashing bios? Because the card has the exact same architecture as a 570, it's kinda like an overclocked 570 but with different name and ID.

Since this is not a VBIOS flashing site. I would go https://www.techpowerup.com/ and get your video card fully working as a RX570 first.

If you want to try to spoof your video card and see if it would work with MacOS
