I’ve found on my z790 msi carbon 14900k, 7200 was pretty easy, just xmp and go, 7400 I had to adjust the voltages as another poster replied, 7600 I can boot but no matter what voltages/loosen timings I cant get it stable. But as others have said on 4 dimm boards over 7000 seems to be hit or miss while I do believe 7200 with the right settings is pretty common to get stable, over that is a crap shoot. Also look into tuning all your timings, a lot of gains to be had.
