Corsair Dominator Titanium RGB DDR5-6600 2x16GB 5600 CL36 vs Kingston ValueRAM DDR5-6400 CUDIMM 1x32GB in detail
True latency
Corsair Dominator Titanium RGB DDR5-6600 2x16GB 5600 CL36 is the lower-latency kit at 12.86 ns against 16.25 ns for Kingston ValueRAM DDR5-6400 CUDIMM 1x32GB, 3.39 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 Dominator Titanium RGB DDR5-6600 2x16GB 5600 CL36 runs 5600 MT/s at CL36; Kingston ValueRAM DDR5-6400 CUDIMM 1x32GB runs 6400 MT/s at CL52.
Transfer rate
Kingston ValueRAM DDR5-6400 CUDIMM 1x32GB carries the higher rating, 6400 MT/s to 5600 MT/s for Corsair Dominator Titanium RGB DDR5-6600 2x16GB 5600 CL36 — 51200 MB/s per module against 44800 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
Corsair Dominator Titanium RGB DDR5-6600 2x16GB 5600 CL36 is tracked at £489.00, or £15.28 per gigabyte; Kingston ValueRAM DDR5-6400 CUDIMM 1x32GB at £451.55, or £14.11. At the same 32GB, that puts Kingston ValueRAM DDR5-6400 CUDIMM 1x32GB £37.45 less than Corsair Dominator Titanium RGB DDR5-6600 2x16GB 5600 CL36. Corsair Dominator Titanium RGB DDR5-6600 2x16GB 5600 CL36's £489.00 sits 14% under its own 90-day median. Kingston ValueRAM DDR5-6400 CUDIMM 1x32GB's £451.55 sits 13% under its own 90-day median.
Kit layout
Corsair Dominator Titanium RGB DDR5-6600 2x16GB 5600 CL36 ships as 2 × 16GB, Kingston ValueRAM DDR5-6400 CUDIMM 1x32GB ships as 1 × 32GB. A real difference, and not a ranking: more sticks fill more channels on a board that has them, while fewer sticks leave slots free for adding later. Which suits comes down to the board and to whether more memory is planned.
Lighting, timings and ECC
On lighting: Corsair Dominator Titanium RGB DDR5-6600 2x16GB 5600 CL36 has RGB lighting, and Kingston ValueRAM DDR5-6400 CUDIMM 1x32GB is published with no RGB lighting. On the full timing tuple — the numbers after CAS — Corsair Dominator Titanium RGB DDR5-6600 2x16GB 5600 CL36 is 32-39-39-76, and Kingston ValueRAM DDR5-6400 CUDIMM 1x32GB publishes none. On error correction: Corsair Dominator Titanium RGB DDR5-6600 2x16GB 5600 CL36 is published without ECC, and the catalog does not state whether Kingston ValueRAM DDR5-6400 CUDIMM 1x32GB has it. 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
There is no single answer here, because each kit leads on one axis. Kingston ValueRAM DDR5-6400 CUDIMM 1x32GB is the cheaper at the prices tracked here, and Corsair Dominator Titanium RGB DDR5-6600 2x16GB 5600 CL36 the quicker on true latency at 12.86 ns against 16.25 ns. Which matters more depends on the build and the budget, and that is not a call this page can make.
Common questions about this pair
- Is Corsair Dominator Titanium RGB DDR5-6600 2x16GB 5600 CL36 faster than Kingston ValueRAM DDR5-6400 CUDIMM 1x32GB?
- Yes, on true latency: 12.86 ns for Corsair Dominator Titanium RGB DDR5-6600 2x16GB 5600 CL36 against 16.25 ns for Kingston ValueRAM DDR5-6400 CUDIMM 1x32GB.
