The PC will only use one RAM stick after upgrading the CPU to a Ryzen 5600.
Specs:
Mobo: Gigabyte A520M S2H
CPU: Ryzen 5600 (just upgraded from 2600)
GPU: RX 7600
RAM: 2 x 8GB Corsair Vengeance LPX DDR4 3200Mhz
I had already updated to most recent BIOS few weeks prior.
I acutally bought a Ryzen 5600 a month ago and I had the same issue. After a bunch of reading through forms and trying all the suggestions I could find. I decided it was possibly faulty memory controller in the CPU so I returned it and got my money back.
I decided to buy a new one again as they were on sale. Came today, brand new sealed.
Same Issue again.
Prior to upgrading the CPU, everything worked fine with my Ryzen 2600.
I reset the BIOS settings.
Installed the new Ryzen 5600
Booted but no POST.
Removed 1 RAM stick and it will POST.
Enabled XMP and tried with 2 sticks. Didnt work.
Tried Swaping slots. Both sticks will work in either slot (Motherboard only has 2 slots) but just not together.
I've reset CMOS.
I just ordered two new RAM sticks. Crucial Pro DDR4 RAM 32GB Kit (2x16GB) 3200MHz to see if maybe the RAM somehow became faulty, but like I said, both sticks worked. Both slots on the motherboard worked. Just would not work together.
I refuse to believe it could possibly be a fault with the memory controller in two seperate CPU's? Unless this is a common issue that is not reported too much with the Ryzen 5 5600?
Updated / Fixed
New RAM arrived today. I installed both modules and everything started working properly!
This motherboard?

Some boards need the first RAM slot to hold a particular type, usually DIMMA2.
This seems not to be your case.
Examine the installed RAMs and settings in Sections 2-4 of the User Guide (pages 9 & 10).
Check the bottom of Page 9 for any updates or changes related to RAM.
Also remember to "reset" the CMOS as instructed in Paragraph 17 on Page 19.
