RX 580 (MSI): Black screen after verbose

[Lost-Entrepreneur439]

After the verbose log on my MSI RX 580 Gaming X 4GB, the screen just goes black. There's no noticeable errors so I'm not sure what's going on. I've tested with multiple different monitors and it happens across all of them with both HDMI and DVI. I don't have a DisplayPort monitor or adapter to test. Anyone know how I could resolve this?

use one of these boot args: agdpmod=pikera or agdpmod=vit9696 add it under NVRAM -> boot-args

I tried both, neither worked unfortunately.

You chosen model iMac14,2 but the model assumes Nvidia graphics.

Change to iMac18,3 which assumes RX580.

Some ROMS like Chinese 2048sp need enable CSM. If your hardware is native RX 580 4GB, maybe ROM need update or need flash to Sapphire ROM 4GB. 

 

I will test my card RX 580 Sapphire 4GB and report here...

 

EDIT: Also same almost  results here, using Clover 5160 and iMacPro1,1, two monitors and one HDMI one Dvi, stuck on verbose screen. 

 

I will try using recommendation by @Cyberdevs 

 

Spoiler

Mine is the standard, not the 2048sp. It's on the latest vBIOS available and the Sapphire one uses a different vRAM brand so it's incompatible iirc.
