Overclocking profilesiProfiles stored on the modules. EXPO ULL is AMD's EXPO Ultra Low Latency profile. None means the kit has no XMP or EXPO profile and runs from its default SPD settings. This includes a faster default speed with no profile, such as Kingston Plug N Play. Every DDR5 kit listed as Intel XMP is XMP 3.0. Every DDR4 kit listed as Intel XMP is XMP 2.0. The order follows the maker's list, profile 1 first.

Intel XMP 3.0, None (no XMP or EXPO)2Maker spec sheet (PDF)kingston.com/datasheets/KF556S40IBK2-32.pdfRead 15 October 2026Datasheets of the 4800, 6000 and 6400 MT/s kits list XMP profiles and say the module supports Intel XMP 3.0. The 5600 MT/s datasheets list only a Plug N Play default and no XMP profile, so they are stored as None. Kingston retail listings and the press release say Intel XMP 3.0 certified for the line, which conflicts with the 5600 MT/s datasheets.

Default speed (JEDEC)iSpeed the kit runs at without a profile. Makers call it SPD speed or default speed. The data rate in MT/s. A maker's SPD speed written in MHz, such as 5600MHz, is 5600 MT/s. A tool such as CPU-Z shows half the data rate, so DDR5-2400 in CPU-Z is 4800 MT/s.

DDR5 JEDEC speeds start at 4800, so these values look like page errors and the default fields are left out of those rows.

Module heightiHeight of one module from the bottom edge of the contacts to the top, with the heat spreader and light bar as sold. It decides the clearance under large CPU air coolers. This is the vertical height standing in the slot, not the board thickness. Makers write L x W x H, and some call the standing height W. Use the middle number of the three. A size with only two numbers gives length and height, so the smaller is the height. The longest is the module length and the smallest the thickness.
