[Success] Radeon RX 6800 XT - Big Sur

I tried it, but the same thing happens, I don't notice anything

Did you clear NVRAM? Whenever we make changes to the boot-args we need to clear NVRAM on the next boot or they won't be applied.

I did not do it, I do not know how to do it

At the OC picker press the space bar. There should then be the option to clear nvram.

I'll give it a try, thanks for everything.

I am excited to hear that this is finally working; however, I am having trouble finding any working cards/brands lists. I just ordered the "ASUS Radeon RX 6800 XT TUF OC". Was it a good choice? If not, what should I look for?

I really appreciate any help you can provide.


EDIT:
Saw an earlier post that said if the device ID ended in "73BF," it would work, which my card has.

Hello
How you "ASUS Radeon RX 6800 XT TUF OC" working ?
thanks in advance

1- Update all kexts
2- adding agdpmod=pikera in boot-args
3- remove the RX 580
4- Instal the RX 6900 XT
AND BOMMM!

Alas, no change in AMDX6000HWServices. Supported NAVI devices are still the same 0x73A21002 0x73AB1002 0x73BF1002.

AMDX6000Framebuffer has the same list of NAVI device IDs as before. Device 0x73DF1002 is RX 6700 XT, but the driver does not yet exist. There is no IOKitPersonality for Navi 22 in AMDRadeonX6000.kext.
