Corsair Vengeance DDR5-6000 2x32GB CL40 vs Corsair Vengeance RGB DDR5-6400 2x32GB CL42 in detail
True latency
Corsair Vengeance RGB DDR5-6400 2x32GB CL42 is the lower-latency kit at 13.13 ns against 13.33 ns for Corsair Vengeance DDR5-6000 2x32GB CL40, 0.21 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. Corsair Vengeance DDR5-6000 2x32GB CL40 runs 6000 MT/s at CL40; Corsair Vengeance RGB DDR5-6400 2x32GB CL42 runs 6400 MT/s at CL42.
Transfer rate
Corsair Vengeance RGB DDR5-6400 2x32GB CL42 carries the higher rating, 6400 MT/s to 6000 MT/s for Corsair Vengeance DDR5-6000 2x32GB CL40 — 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.
Kit layout
Corsair Vengeance DDR5-6000 2x32GB CL40 ships as 2 × 32GB and Corsair Vengeance RGB DDR5-6400 2x32GB CL42 ships as 2 × 32GB — the same number of sticks on both sides, so they populate a board's slots the same way.
Voltage
Corsair Vengeance DDR5-6000 2x32GB CL40 is specified at 1.35 V and Corsair Vengeance RGB DDR5-6400 2x32GB CL42 at 1.4 V. That is the supply each kit's published profile requests from the board.
Lighting and timings
On lighting: Corsair Vengeance DDR5-6000 2x32GB CL40 is published with no RGB lighting, and Corsair Vengeance RGB DDR5-6400 2x32GB CL42 has RGB lighting. On the full timing tuple — the numbers after CAS — Corsair Vengeance DDR5-6000 2x32GB CL40 is 40-50-50-96, and Corsair Vengeance RGB DDR5-6400 2x32GB CL42 is 32-40-40-84.
