Notes: The EXPO on this mem kit with this CPU and BIOS did just work. So all I did was tighten the timings. I'll be testing my other A-die kits in the future in order to see if the mem kit or BIOS version are the main reason for this being so easy to set up because historically I've not had much success with getting DDR5-8000 to work with 16Gb A-die.
