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.

ECC memoryiThe board runs unbuffered ECC modules with ECC active. A board that runs ECC modules in non-ECC mode does not count. DDR5 on-die ECC does not count. 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. A note that ECC mode depends on the CPU, as ASUS writes for AM4 boards, still counts as true.
