The same page also has a block that says 12+2 DrMOS power stages rated 60 A. That block is identical to the one on the ASUS PRIME B650-PLUS WIFI page and conflicts with discrete MOSFETs, so the board-specific sentence is stored.

CPU core (Vcore) power stagesiPower stages on the Vcore rail. Makers call them phases or power stages. A doubled design has more stages than controller phases. Use the first number of the maker's layout, such as 14 for MSI's 14+2+1 Duet Rail. A review's different count goes in the source note.

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.

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.
