Crucial Pro DDR5-6400 Overclocking Memory 2x16GB vs Crucial Pro DDR5-6000 Overclocking Memory 2x16GB in detail
True latency
Crucial Pro DDR5-6400 Overclocking Memory 2x16GB is the lower-latency kit at 10.00 ns against 12.00 ns for Crucial Pro DDR5-6000 Overclocking Memory 2x16GB, 2.00 ns between them. That is the figure that reconciles the two spec sheets: a CAS number counts cycles, and cycles mean nothing apart from the rate they are counted at. Crucial Pro DDR5-6400 Overclocking Memory 2x16GB runs 6400 MT/s at CL32; Crucial Pro DDR5-6000 Overclocking Memory 2x16GB runs 6000 MT/s at CL36.
Transfer rate
Crucial Pro DDR5-6400 Overclocking Memory 2x16GB carries the higher rating, 6400 MT/s to 6000 MT/s for Crucial Pro DDR5-6000 Overclocking Memory 2x16GB — 51200 MB/s per module against 48000 MB/s. That is peak transfer rate, not access time: a higher clock is reached by counting more cycles for each access, which is why the CAS numbers differ too and why the true latency above is the directly comparable figure.
Price and tracked history
Crucial Pro DDR5-6400 Overclocking Memory 2x16GB is tracked at £442.74, or £13.84 per gigabyte; Crucial Pro DDR5-6000 Overclocking Memory 2x16GB at £399.99, or £12.50. At the same 32GB, that puts Crucial Pro DDR5-6000 Overclocking Memory 2x16GB £42.75 less than Crucial Pro DDR5-6400 Overclocking Memory 2x16GB.
Kit layout
Crucial Pro DDR5-6400 Overclocking Memory 2x16GB ships as 2 × 16GB and Crucial Pro DDR5-6000 Overclocking Memory 2x16GB ships as 2 × 16GB — the same number of sticks on both sides, so they populate a board's slots the same way.
Lighting and timings
On lighting: Crucial Pro DDR5-6400 Overclocking Memory 2x16GB is published with no RGB lighting, and Crucial Pro DDR5-6000 Overclocking Memory 2x16GB is published with no RGB lighting.
