Speed DDR4 2666

Color Black

  • 64 GB dual-channel kit expands multitasking headroom for demanding workloads
  • 2666 MHz DDR4 speed delivers high bandwidth for faster data throughput
  • CL19 latency at 2666 MHz balances responsive timing with broad compatibility
  • 2 V low-voltage operation reduces power draw and heat in compact systems
  • 260-pin SODIMM form factor fits DDR4 laptops, notebooks, mini PCs and all-in-ones

Capacity and form factor

This Timetec kit provides 64GB of DDR4 laptop memory across two 32GB SODIMM modules. It is built for notebooks, mini PCs and all-in-one systems that accept 260-pin DDR4 memory. The non-ECC unbuffered design suits consumer platforms.

Speed and latency

The modules run at 2666MHz with a CAS latency of CL19 and operate at 1.2V. They are rated PC4-21300 and use a dual-rank 2Rx8 organisation on black PCBs. Compatibility is limited to systems that support DDR4 SODIMM slots.

Who this suits and who it does not

Builders upgrading compatible laptops or compact PCs to 64GB will find a plug-and-play fit. Buyers with desktop DIMM slots, DDR3-only platforms or systems that do not support 32GB per slot should look elsewhere.

Questions about this item

What does the 2666 MHz speed mean once the modules are installed in my laptop?

The kit will run at up to 2666 MHz if your system supports that frequency; otherwise it automatically steps down to 2400 MHz or 2133 MHz with matching CAS latencies of CL17 or CL15.

The listing mentions PC4-21300 — what does that cap in practice?

PC4-21300 is the peak transfer rate label for DDR4-2666; real-world bandwidth is limited by your laptop's memory controller and the dual-rank 2Rx8 organisation of these modules.

Will the 67.6 mm × 30 mm sticks fit my 260-pin SODIMM slot?

Yes — each module measures 67.6 mm by 30 mm, uses the standard 260-pin DDR4 SODIMM form factor and operates at 1.2 V, matching the slot specification.
