Crucial Pro DDR5-6400 Overclocking Memory 2x32GB CL40 vs Silicon Power Storm RGB DDR5-6000 CL38 2x32GB in detail

True latency

Crucial Pro DDR5-6400 Overclocking Memory 2x32GB CL40 is the lower-latency kit at 12.50 ns, against 12.67 ns for Silicon Power Storm RGB DDR5-6000 CL38 2x32GB — a difference of 0.17 ns. That figure is what reconciles the two spec sheets: CAS latency counts clock cycles, so it only means something next to the clock it counts. Crucial Pro DDR5-6400 Overclocking Memory 2x32GB CL40 runs 6400 MT/s at CL40; Silicon Power Storm RGB DDR5-6000 CL38 2x32GB runs 6000 MT/s at CL38.

Transfer rate

Crucial Pro DDR5-6400 Overclocking Memory 2x32GB CL40 is rated 6400 MT/s against 6000 MT/s for Silicon Power Storm RGB DDR5-6000 CL38 2x32GB — 51200 MB/s per module, against 48000 MB/s. That is peak transfer rate, not access time: reaching a higher clock costs more cycles on each access, which is why the CAS numbers differ too, and why the true latency above is the figure that compares directly.

Price and tracked history

Crucial Pro DDR5-6400 Overclocking Memory 2x32GB CL40 is tracked at 899,99 € — 14,06 € per gigabyte — and Silicon Power Storm RGB DDR5-6000 CL38 2x32GB at 999,99 €, or 15,62 €. Both are 64GB kits, so the totals compare directly: Crucial Pro DDR5-6400 Overclocking Memory 2x32GB CL40 is 100,00 € less than Silicon Power Storm RGB DDR5-6000 CL38 2x32GB.

Kit layout

Crucial Pro DDR5-6400 Overclocking Memory 2x32GB CL40 ships as 2 × 32GB and Silicon Power Storm RGB DDR5-6000 CL38 2x32GB ships as 2 × 32GB — the same number of sticks either way, so both populate a board's slots identically.

Lighting and timings

On the lighting question: Crucial Pro DDR5-6400 Overclocking Memory 2x32GB CL40 does not have RGB lighting, and Silicon Power Storm RGB DDR5-6000 CL38 2x32GB is published with RGB lighting. On the full timing tuple, the numbers that follow CAS: Crucial Pro DDR5-6400 Overclocking Memory 2x32GB CL40 runs 32-40-40-103, and Silicon Power Storm RGB DDR5-6000 CL38 2x32GB does not publish one.

Which to buy

Crucial Pro DDR5-6400 Overclocking Memory 2x32GB CL40 leads Silicon Power Storm RGB DDR5-6000 CL38 2x32GB on both of the axes this page measures: the lower true latency, 12.50 ns against 12.67 ns, and the lower price of the two at what this site has tracked.

Common questions about this pair

Is Crucial Pro DDR5-6400 Overclocking Memory 2x32GB CL40 faster than Silicon Power Storm RGB DDR5-6000 CL38 2x32GB?
Crucial Pro DDR5-6400 Overclocking Memory 2x32GB CL40 is, on true latency: 12.50 ns against 12.67 ns. Crucial Pro DDR5-6400 Overclocking Memory 2x32GB CL40 runs 6400 MT/s at CL40 and Silicon Power Storm RGB DDR5-6000 CL38 2x32GB runs 6000 MT/s at CL38; the CAS numbers alone do not settle it, because they count clock cycles rather than time.
