Using DDR5 with XMP profiles on AM5?

There are a lot more DDR5 kits with XMP profiles than DDR5 kits with EXPO or dual XMP/EXPO right now. What are the advantages / disadvantages to going with an XMP only kit on AM5?

The specific kit I have my eye on is a G.SKILL Ripjaws S5 64GB DDR5 6000 CL32 kit which looks like the most flexible 64GB kit right now - good performance, low profile for good sff compatibility if I want to go that route in the future without buying new RAM and no RGB that requires invasive software if I want to disable it later (F5-6000J3238G32GX2-RS5K). I would be using it in an Asus B650E-I board with a 7950X (or 7950X3d).

EDIT: Buildzoid highlighted this specific kit as Hynix M-die so hopefully it'll handle being clocked up higher if needed and will last me a cpu upgrade or two.
 
Second that, if I enable XMP my desktop black screens and MW 2 crashes, Intel reps tell me the XMP can be finnicky with games and desktop crashes. I have the 32 Gig GSKILL Trident Z Neo 3600 DDR4 sticks.
 
As I understand it Zen4 will work with XMP perfectly up to 5600. After that you need to manually configure or buy AMD approved kits.
 
Going to tag on here since its right in the wheelhouse of a question I had....

Is there a consensus as to which kit would be better (both EXPO kits from G.SKILL)....

64GB CL32-38-38-96

or

64GB CL30-40-40-96

Same transfer rate? because if not, the numbers aren't comparable.

GIven same transfer rate, I'm not sure it would matter unless there's some reason to believe that one is much more tunable than the other. The actual timing difference is a fraction of a nanosecond.

Given it's very hard to tighten the tRCD value of hynix kits, IMHO the CL32 one is of better bet.

This was my thinking as well. The 6000 CL32 kits seems like the best bet for getting hynix.

For value the 5600 CL32 kits seem much better though (~$270 vs ~$330).

haven't tried 5600 cl32 kit but if it's hynix m-die or samsung, it's of lower bin but still probably pull off 5800 / 6000 @32-40-40-32 or 30-38-38-30.

if you're planning on not changing the dram kits often, going higher binned one is worth it.
