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.
