Rx 580 2048sp Chinese edition

Hello guys I bought a new gpu to replace my unsupported hd 7900 and I traded it in for with a friend it was supposed to be the rx 580 but it’s actually rx 580 2048sp 8gb. I couldn’t get it to work in Sonoma I read a bit online and apparently I have to flash a bios to it using atiflash utility. Can anybody provide me with a guide or a file to flash? It’s my first time doing such stuff and I’m scared of breaking the gpu.

Cpu: i5 6500 Gpu: intel hd graphics 530 + rx 580 2048sp Motherboard:msi b150 pc mate WiFi:Realtek wireless USB adapter macOS version: macOS sonoma beta Smbios: iMacPro1,1
