Cool. You'll gain quite a bit of performance with XMP on, as 2133Mhz with bad timings will severely limit the 11900k. Tested BFV since setting XMP?
Your motherboard BIOS is very old, from January. The latest BIOS has fixes, performance improvements and new microcode for Rocket Lake, which will further improve things.

Link above is to the WIFI edition of the motherboard - not sure if you have this or the non wifi one. Either way, update to Version 0707 ASAP, and turn back on XMP!
Be noted, these BIOS updates that contain CPU microcode updates seem quite scary when updating - they'll reboot you PC several times, you'll get quite a few black screens while it loads the microcode updater. Let it run until you're back at POST (my Maximus XIII board took around 4 minutes!)
