Max memory speed (overclocked)iHighest overclocked speed the maker lists for one module per channel, with the newest CPU family the board is sold for, e.g. Ryzen 9000 or Core Ultra 200S. 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 table that names the CPU family wins over a headline speed that names none.

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.
