Corsair Vengeance LPX DDR4-3200 2x16GB 2666 CL16 vs Crucial Ballistix DDR4-3200 4x8GB 2400 CL16 in detail
True latency
Corsair Vengeance LPX DDR4-3200 2x16GB 2666 CL16 is the lower-latency kit at 12.00 ns against 13.33 ns for Crucial Ballistix DDR4-3200 4x8GB 2400 CL16, 1.33 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 LPX DDR4-3200 2x16GB 2666 CL16 runs 2666 MT/s at CL16; Crucial Ballistix DDR4-3200 4x8GB 2400 CL16 runs 2400 MT/s at CL16.
Transfer rate
Corsair Vengeance LPX DDR4-3200 2x16GB 2666 CL16 carries the higher rating, 2666 MT/s to 2400 MT/s for Crucial Ballistix DDR4-3200 4x8GB 2400 CL16 — 21328 MB/s per module against 19200 MB/s. That is peak transfer rate, not access time. Both kits are published at CL16, so an identical count of cycles simply completes sooner at the higher clock, and the true latency above is the figure that compares directly.
Kit layout
Corsair Vengeance LPX DDR4-3200 2x16GB 2666 CL16 ships as 2 × 16GB, Crucial Ballistix DDR4-3200 4x8GB 2400 CL16 ships as 4 × 8GB. 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 Vengeance LPX DDR4-3200 2x16GB 2666 CL16 is published with no RGB lighting, and Crucial Ballistix DDR4-3200 4x8GB 2400 CL16 is published with no RGB lighting. On the full timing tuple — the numbers after CAS — Corsair Vengeance LPX DDR4-3200 2x16GB 2666 CL16 is 16-20-20-38, and Crucial Ballistix DDR4-3200 4x8GB 2400 CL16 publishes none. On error correction: Corsair Vengeance LPX DDR4-3200 2x16GB 2666 CL16 is published without ECC, and the catalog does not state whether Crucial Ballistix DDR4-3200 4x8GB 2400 CL16 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
At least one of these kits has no tracked price right now, so this page has no buying answer to give: which is worth more depends on what each costs, and that is exactly what is missing. On specifications alone, Corsair Vengeance LPX DDR4-3200 2x16GB 2666 CL16 has the lower true latency at 12.00 ns.
