GUIDE How to Enable AMD RX 6800, RX 6800XT and RX 6900XT on macOS Big Sur and Later

If your BIOS settings is changing, replace the CMOS.

Sorry I was not clear. When I boot to windows I need rebar but hackintosh won’t boot with it. So every time I switch to windows to play games I need to change bios. Is there a setting to make hackintosh boot with rebar on

AMD 6900xt is working great in Big Sur however anytime I try to do HEVC transcoding in compressor or sending iMessage video the system would stall 50% of the time. On Monterey beta 5 it works 100% of the time. However, if I use HDMI to my TV + display port then on wake from sleep it would have a black screen until I remove HDMI and replugin display port. I have tried using this with and without Whatevergreen and both have the same issue. Any suggestions?

See attached for EFI/OC folder. I only stripped out serial number. This is the version with Whatevergreen active.

Not as per the guide. Looks like you're using someone else's configuration.
