RTX 3080 cannot disable with SSDT, DeviceProperties, boot-arg etc

[Connor Salisbury]

I'm running Big Sur on an Alder Lake system with 2 GPUs.

I have an RTX 3080 I use for gaming in Windows and got an RX 560 for use with macOS. I have had a number of GFX related issues whilst trying to get macOS running. 

I now have a working install of Big Sur but I am limited to VESA driver and macOS is not using the RX 560. Both cards are visible in system info, both are named 'Display' and 3080 is GFX0, AMD is GFX1. The RX 560 is supported and I have had it working in a previous install but macOS would not boot if the 3080 was also installed, only booting when I removed it so I started again from scratch, now I have this issue.

I have tried both methods in OC guide (SSDT and DeviceProperties in config.plist) to disable the 3080 but neither work. I have checked the PCI paths and I'm sure they're correct.

Can anybody help?

Thanks

 

I just tried with the 3080 removed and still limited to VESA drivers so I have no idea what is the cause. Like RX 560 drivers aren’t being used but the card worked fine on last install I just couldn’t boot with 3080 also installed.

It is GFX0:

I am able to boot use RX 560 now but still cannot disable 3080 (GFX0) so I have to change DP cable every time.

Thanks

No I only have 1 EFI, but I used GenSMBIOS with MacPro7,1 with the config.plist from olarila alder lake build. Was that wrong to do? I thought MacPro7,1 was correct for my hardware

use this efi folder and dont change nothing for now

-Delete old EFI folder and paste new. Don't use merge files
-Don't use Drag and Drop into EFI partition. Use Copy/Paste instead
-Reset NVRAM one time - with OpenCore use entry "Reset Nvram" / with Clover use F11 key on boot screen

This worked, 3080 is disable and this even fixed my CPU temp reporting issues and CPU performance. Geekbench is up from 9000 to 17000. You're a genius

iCloud Keychain was disable though and I can't enable again now

Edit: Keychain fixed
