Crucial Pro DDR5-6400 Overclocking Memory 2x16GB vs G.Skill Flare X5 DDR5-6000 2x16GB in detail
True latency
Both kits land on 10.00 ns. Crucial Pro DDR5-6400 Overclocking Memory 2x16GB gets there at 6400 MT/s at CL32, G.Skill Flare X5 DDR5-6000 2x16GB at 6000 MT/s at CL30. CAS latency counts clock cycles rather than time, so a higher clock paired with a looser CAS number arrives at the same place — which is why these two spec sheets look different and the memory does not.
Transfer rate
Crucial Pro DDR5-6400 Overclocking Memory 2x16GB carries the higher rating, 6400 MT/s to 6000 MT/s for G.Skill Flare X5 DDR5-6000 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; G.Skill Flare X5 DDR5-6000 2x16GB at £549.99, or £17.19. At the same 32GB, that puts Crucial Pro DDR5-6400 Overclocking Memory 2x16GB £107.25 less than G.Skill Flare X5 DDR5-6000 2x16GB.
Kit layout
Crucial Pro DDR5-6400 Overclocking Memory 2x16GB ships as 2 × 16GB and G.Skill Flare X5 DDR5-6000 2x16GB ships as 2 × 16GB — the same number of sticks on both sides, so they populate a board's slots the same way.
Lighting, timings and ECC
On lighting: Crucial Pro DDR5-6400 Overclocking Memory 2x16GB is published with no RGB lighting, and G.Skill Flare X5 DDR5-6000 2x16GB is published with no RGB lighting. On the full timing tuple — the numbers after CAS — Crucial Pro DDR5-6400 Overclocking Memory 2x16GB is 32-40-40-103, and G.Skill Flare X5 DDR5-6000 2x16GB is 30-38-38-96. On error correction: the catalog does not state whether Crucial Pro DDR5-6400 Overclocking Memory 2x16GB has it, and G.Skill Flare X5 DDR5-6000 2x16GB is published without ECC. ECC is a board and CPU feature as much as a module one, so it is worth having only where the platform can use it.
Which to buy
At the prices tracked here Crucial Pro DDR5-6400 Overclocking Memory 2x16GB undercuts G.Skill Flare X5 DDR5-6000 2x16GB, and the two are level on true latency at 10.00 ns. What that separation buys is a lower price, not a quicker kit — nothing on this page says it will feel any different in use.
