Ryzen 8000 values are never used. The source note names the family and the other module setups. It is not the CPU's official speed. A JEDEC-only list such as 5600/4800 is not this value. When the maker lists a manual overclock and a memory profile speed, the higher one is stored. The maker's product page wins over an older manual, since a BIOS update can raise the value.

A maker list of ECC and non-ECC unbuffered memory with no non-ECC mode qualifier counts as true, as on ASUS and ASRock AM5 boards.
