Will a DDR5 motherboard support all DDR5 RAM, no matter the MHz? (further explanation below)

I was able to get my hands on a DDR5 MB and RAM recently. After the upgrade, I’m having trouble getting the PC to post. I googled my symptoms and they mostly pointed towards improper GPU installation (which I was able to rule out), or RAM issues. I singled out the DIMMS to see if one of them was bad to no avail… then I decided to take one last look at the motherboard manual. It says “Support for DDR5 4800/4000 MHz memory modules” - My modules are 5200MHz.

I didn’t even know that DDR5 came in the 4000/4800 MHz variety. My assumptions were that this manual is just out of date, and the motherboard should support DDR5 of all MHz.

Are my assumptions correct?

Greetings. Which brand/model of motherboard and which brand/model of RAM do you have?

Sorry for the delay in response.

Looking at the ASUS website https://www.gigabyte.com/Motherboard/Z690-AORUS-MASTER-rev-10/sp#sp

Here is what it lists for memory supported:

So it only supports up to 4800MHZ without overclocking / setting an XMP profile. So any tweaks to that would have to be set up in the BIOS.
