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.

I do not have this mobo or DDR5 but thought one should consider the mobo as limiting the speed.
Some, will limit the DRAM speed as more DIMMs are added.

Try to install only one DIMM and see if it makes a difference.

Also, I see in the image that you installed in slots A2/B2. Is this what the doco recommends?
