Hi!

Asus TUF B550 Plus
Ryzen 7 5800x3D
Radeon RX 6900 XT

So I just learnt about SAM and what kind of boost it can give to game performance. Updated BIOS and off I went into the BIOS to turn on resizable bar, checked that CSM was disabled and 4G decoding @ auto. After that? I get a notification at startup like this:

Restart won't fix that and on Radeon Adrenalin SAM is still disabled.

I tried to do a clean Adrenalin Suite install with Factory reset enabled (haven't tried DDU route yet) and doing the BIOS changes again to no avail. Still does the same: settings in BIOS are correct and stay through restarts, but in Windows nothing changes. Just that Systems Settings Change restart prompt at startup and SAM stays disabled. Any thoughts about how to proceed?

Thank you in advance.

Use DDU in Safe Mode to remove all GPU drivers(Intel, Nvidia and AMD) then manually install the latest GOU driver sourced from AMD's support site in an elevated command, i.e, Right click installer>Run as Administrator.

Thanks for the replies!

Yeah, it is an UEFI BIOS, sry I didn't make that clear.

Yeah, I got the BIOS side of things right. Turns out it was somehow corrupted AMD drivers. It's AMD that displays that restart prompt and apparently even wiping the drivers and suite by the built-in "factory reset" options won't root out the problem files.

So what did the trick? The nuclear option. DDU and just ticked all AMD boxes in settings. Reinstalled the newest drivers & suite and as the BIOS options were already on, SAM is enabled right from the restart.

Thanks again!
