This exists https://www.igorslab.de/en/jedec-ddr5-9000-intel-arrow-lake-refresh-ryzen-9000-x3d-ram-scaling/4/ except the 1:1:1 mode didn't get a fair fight with 1.35 VDD vs other modes getting cranked upto 1.70-1.85 VDD
Not to mention 9800X3D consistently performing better on 1 stick of ram vs 2 (atleast on CS2 which is all I care about)
Given I'm both a noob and busy I give this quest to some daring adventurerer here to explore further and enlighten the rest of us.
I mean maybe in the latest bios the bug mentioned there is fixed and some expert can tune the 2200 MCLK to the compare results. I do not know why but my stick simply doesnt want to boot below 2400 MCLK.
