Corsair Vengeance LPX DDR4-3200 4x8GB 2666 CL15 vs Patriot Viper Steel DDR4-3200 2x16GB CL18 RGB in detail
True latency
Patriot Viper Steel DDR4-3200 2x16GB CL18 RGB is the lower-latency kit at 11.25 ns against 11.25 ns for Corsair Vengeance LPX DDR4-3200 4x8GB 2666 CL15, 0.00 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 4x8GB 2666 CL15 runs 2666 MT/s at CL15; Patriot Viper Steel DDR4-3200 2x16GB CL18 RGB runs 3200 MT/s at CL18.
Transfer rate
Patriot Viper Steel DDR4-3200 2x16GB CL18 RGB carries the higher rating, 3200 MT/s to 2666 MT/s for Corsair Vengeance LPX DDR4-3200 4x8GB 2666 CL15 — 25600 MB/s per module against 21328 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 LPX DDR4-3200 4x8GB 2666 CL15 ships as 4 × 8GB, Patriot Viper Steel DDR4-3200 2x16GB CL18 RGB ships as 2 × 16GB. 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 4x8GB 2666 CL15 is published with no RGB lighting, and Patriot Viper Steel DDR4-3200 2x16GB CL18 RGB has RGB lighting. On the full timing tuple — the numbers after CAS — Corsair Vengeance LPX DDR4-3200 4x8GB 2666 CL15 is 16-20-20-38, and Patriot Viper Steel DDR4-3200 2x16GB CL18 RGB is 16-20-20-40. On error correction: Corsair Vengeance LPX DDR4-3200 4x8GB 2666 CL15 is published without ECC, and the catalog does not state whether Patriot Viper Steel DDR4-3200 2x16GB CL18 RGB 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
Without a tracked price for both, this page cannot say which to buy — the answer depends on cost, and cost is what is absent. What the specifications do say is that Patriot Viper Steel DDR4-3200 2x16GB CL18 RGB has the lower true latency, 11.25 ns.
Common questions about this pair
- Is Corsair Vengeance LPX DDR4-3200 4x8GB 2666 CL15 faster than Patriot Viper Steel DDR4-3200 2x16GB CL18 RGB?
- Yes, on true latency: 11.25 ns for Patriot Viper Steel DDR4-3200 2x16GB CL18 RGB against 11.25 ns for Corsair Vengeance LPX DDR4-3200 4x8GB 2666 CL15. Corsair Vengeance LPX DDR4-3200 4x8GB 2666 CL15 runs 2666 MT/s at CL15 and Patriot Viper Steel DDR4-3200 2x16GB CL18 RGB runs 3200 MT/s at CL18, and the CAS numbers alone will not settle it — they count clock cycles, not time.
