A-Tech 16GB DDR4-2666 UDIMM Kit 32GB Kit (2x16GB) vs Timetec Premium DDR4-2666 UDIMM 2x16GB 2400 CL17 in detail
True latency
Timetec Premium DDR4-2666 UDIMM 2x16GB 2400 CL17 is the lower-latency kit at 14.17 ns, against 14.25 ns for A-Tech 16GB DDR4-2666 UDIMM Kit 32GB Kit (2x16GB) — a difference of 0.09 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. A-Tech 16GB DDR4-2666 UDIMM Kit 32GB Kit (2x16GB) runs 2666 MT/s at CL19; Timetec Premium DDR4-2666 UDIMM 2x16GB 2400 CL17 runs 2400 MT/s at CL17.
Transfer rate
A-Tech 16GB DDR4-2666 UDIMM Kit 32GB Kit (2x16GB) is rated 2666 MT/s against 2400 MT/s for Timetec Premium DDR4-2666 UDIMM 2x16GB 2400 CL17 — 21328 MB/s per module, against 19200 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.
Kit layout
A-Tech 16GB DDR4-2666 UDIMM Kit 32GB Kit (2x16GB) ships as 2 × 16GB and Timetec Premium DDR4-2666 UDIMM 2x16GB 2400 CL17 ships as 2 × 16GB — the same number of sticks either way, so both populate a board's slots identically.
Lighting and ECC
On the lighting question: A-Tech 16GB DDR4-2666 UDIMM Kit 32GB Kit (2x16GB) does not have RGB lighting, and Timetec Premium DDR4-2666 UDIMM 2x16GB 2400 CL17 does not have RGB lighting. On error correction: A-Tech 16GB DDR4-2666 UDIMM Kit 32GB Kit (2x16GB) is published with no ECC, and Timetec Premium DDR4-2666 UDIMM 2x16GB 2400 CL17 is published with no ECC. Whether ECC is worth having depends on the platform as much as the modules — the board and the CPU have to support it too.
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, Timetec Premium DDR4-2666 UDIMM 2x16GB 2400 CL17 has the lower true latency at 14.17 ns.
Common questions about this pair
- Is A-Tech 16GB DDR4-2666 UDIMM Kit 32GB Kit (2x16GB) faster than Timetec Premium DDR4-2666 UDIMM 2x16GB 2400 CL17?
- Timetec Premium DDR4-2666 UDIMM 2x16GB 2400 CL17 is, on true latency: 14.17 ns against 14.25 ns. A-Tech 16GB DDR4-2666 UDIMM Kit 32GB Kit (2x16GB) runs 2666 MT/s at CL19 and Timetec Premium DDR4-2666 UDIMM 2x16GB 2400 CL17 runs 2400 MT/s at CL17; the CAS numbers alone do not settle it, because they count clock cycles rather than time.
