Radeon Compatibility Guide - ATI/AMD Graphics Cards

Ok, so the original question remains, do I need to use inject ATI when using the Load Vbios option in Clover?

No. No need to inject anything past later versions of high Sierra.

Also what do you mean load vbios. Avoid any extra things. Because these cards work oob.

Yes, inject ATI to load vbios. Good luck!

I've seen people have issues with this option in Clover and instabilities in macOS.

I would recommend just using the AMD Flash Tool in Windows to flash that XFX card with a proper Sapphire VBIOS.

RX580 has dual vBIOS, so you can have the Sapphire on one vbios and original one on another.

And also you can always flash back to the original vbios when necessary (I recommend making a backup of it first with the AMD tool and storing it in the cloud or somewhere safe)

Very interesting, if I load the AMDRadeonVII.kext my system won't boot even.

Are you using IGPU or at least headless?

 

[MACAK]

Headless, I can try with the IGPU though.

For anyone thinking of getting the Radeon, I did get mine today. All I did was take out my Radeon RX580 and install the VII and it booted up as a Radeon Vega 16GB. No issues at all as I am running 10.14.4 already. It is working well for me. Looking forward to 10.14.5 if it has it.

Why My RX 580 Work just using DeInit on High Sierra 10.13.6 ?

Does anyone suffer from crackling audio from a Vega card through DisplayPort audio (monitor has speakers)?
