PSA, make sure you do a hard reset (short the RTC) on many z690 mobos that have been upgraded from Alder to Raptor. I just partially fried my 13900K somehow after replacing a 12900K in an Asus TUF Z690 Plus DDR4 motherboard. I upgraded to the latest firmware on Asus' site, shorted the RTC jumper while power was cut off and I thought I was golden. Booted up fine and worked well for a day or so after enabling XMP. Today, will no longer boot at XMP speeds and my M.2 slot 1 has gone bad. Found out the stupid motherboard was running the CPU at 1.5 volts for some reason, I thought the high temps was just expected with RL. In other words, the CMOS didn't reset when I shorted the RTC jumper with power off. I then shorted the RTC while computer was on. It was then everything was reset, but damage already occurred. Putting back my 12900K results in booting fine at XMP and M.2 slot 1 working again.
