Your BIOS is probably set in EZ mode and as Richad said, you probably need to tweak some XMP or EXPO modes in the BIOS to get the most out of the modules.
The motherboard manual is here: https://download.msi.com/archive/mnu_exe/mb/PROB650-PWIFI.pdf But doesn't go into a ton of detail about specific BIOS settings.

I've just had a fiddle in my AM5 BIOS and while it's not *immediately* obvious, you can enable EXPO by clicking the A-XMP profile 'button' until it's shaded.
Save and exit. Your machine will restart itself a few times and then you should get the most out of your memory modules.

Apologies in advance if this is too OT.
I recently installed a new system based on an MSI B650-P motherboard
with an AMD Ryzen 7600 and Corsair DDR5 RAM. The RAM specs show a
recommended frequency of 5200 MHz, but the UEFI screen shows it running
at 4800MHz (even though it also notes the correct spec). Here's a
screenshot link:

The MSI docs are atrocious and I can't see any way of changing the DRAM
frequency.
Not a big deal really but if anyone has any ideas I'd appreciate the
feedback.
