G.Skill Ripjaws V DDR4-3600 2x16GB vs Timetec Premium DDR4-2666 UDIMM 2x16GB in detail
True latency
G.Skill Ripjaws V DDR4-3600 2x16GB is the lower-latency kit at 8.89 ns, against 14.25 ns for Timetec Premium DDR4-2666 UDIMM 2x16GB — a difference of 5.37 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. G.Skill Ripjaws V DDR4-3600 2x16GB runs 3600 MT/s at CL16; Timetec Premium DDR4-2666 UDIMM 2x16GB runs 2666 MT/s at CL19.
Transfer rate
G.Skill Ripjaws V DDR4-3600 2x16GB is rated 3600 MT/s against 2666 MT/s for Timetec Premium DDR4-2666 UDIMM 2x16GB — 28800 MB/s per module, against 21328 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.
Price and tracked history
G.Skill Ripjaws V DDR4-3600 2x16GB is tracked at £259.26 — £8.10 per gigabyte — and Timetec Premium DDR4-2666 UDIMM 2x16GB at £164.99, or £5.16. Both are 32GB kits, so the totals compare directly: Timetec Premium DDR4-2666 UDIMM 2x16GB is £94.27 less than G.Skill Ripjaws V DDR4-3600 2x16GB. At £259.26, G.Skill Ripjaws V DDR4-3600 2x16GB is running 8% below its own 90-day median. At £164.99, Timetec Premium DDR4-2666 UDIMM 2x16GB is running 5% below its own 90-day median.
Kit layout
G.Skill Ripjaws V DDR4-3600 2x16GB ships as 2 × 16GB and Timetec Premium DDR4-2666 UDIMM 2x16GB ships as 2 × 16GB — the same number of sticks either way, so both populate a board's slots identically.
Voltage
G.Skill Ripjaws V DDR4-3600 2x16GB is specified at 1.35 V and Timetec Premium DDR4-2666 UDIMM 2x16GB at 1.2 V. That is the supply each kit's published profile asks the board for.
Lighting, timings and ECC
On the lighting question: G.Skill Ripjaws V DDR4-3600 2x16GB does not have RGB lighting, and Timetec Premium DDR4-2666 UDIMM 2x16GB does not have RGB lighting. On the full timing tuple, the numbers that follow CAS: G.Skill Ripjaws V DDR4-3600 2x16GB runs 16-19-19-39, and Timetec Premium DDR4-2666 UDIMM 2x16GB does not publish one. On error correction: the catalog does not state whether G.Skill Ripjaws V DDR4-3600 2x16GB supports it, and Timetec Premium DDR4-2666 UDIMM 2x16GB 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
The two split the axes this page measures, so no one kit is the answer. The lower tracked price belongs to Timetec Premium DDR4-2666 UDIMM 2x16GB; the lower true latency to G.Skill Ripjaws V DDR4-3600 2x16GB, 8.89 ns against 14.25 ns. Weighing money against latency is a decision about the machine, and it stays with the reader.
