8 of 8 differ

Rated speediData rate of the kit's fastest XMP or EXPO profile, the speed on the label. A kit without a profile shows its JEDEC speed. A speed the maker writes in MHz, such as 6000MHz, is the data rate, so it is 6000 MT/s.

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.

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.

The sheet writes the speed in MHz. It is the DDR4 data rate, stored as MT/s.

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.

AIDA64 memory test (measured)iAIDA64 Cache and Memory Benchmark results from a reviewer, one row per tested kit and setting. Read, write and copy are in MB/s as AIDA64 prints them, where 1 MB is 1,048,576 bytes. Results depend on the CPU and board, so compare rows from the same CPU only. AIDA64 switches a result of 100 GB/s or more to GB/s, where 1 GB is 1024 MB, so 113.64 GB/s is stored as 116367 MB/s, rounded to a whole MB/s. The printed figure goes in the source note.
