As far as I'm aware RAM overclocking is managed in the command centre try this, 1.) Open command centre and ensure it's in full screen. 2.) Click on the fusion tab 3.) Click on advanced view next to memory clock. 4.) Select RAM2 in the drop down box and save it as a new profile.
Any attempts to overclock with the Command Center utility disables XMP in bios and there is no way to set it in the Command Center. I have to disable overclocking in the bios and set XMP back on so it will clear the Command Center settings, otherwise, if I enable XMP in the BIOS, when Windows starts, the Command Center disables XMP in the BIOS again.  It's a new R11, Core i7, RTX 3080
