Speed DDR4 2666 (PC4 21300)

CAS Latency CL19

  • 64 GB total capacity from four 16 GB modules
  • DDR4 2666 MHz speed rated as PC4-21300
  • CL19 CAS latency at standard 1.2 V operation
  • 260-pin SODIMM form factor fits compatible laptops
  • Unbuffered non-ECC design with major-brand DRAM ICs

Capacity and Compatibility

This A-Tech kit delivers 64GB of DDR4 memory across four 16GB SODIMM modules. It is built for laptops, notebooks and all-in-one PCs that accept 260-pin DDR4 SO-DIMMs and can run at 2666MHz. The unbuffered, non-ECC design matches the requirements of most consumer mobile platforms.

Sustained Workload Behaviour

Rated at CL19 latency and the standard 1.2V operating voltage, the modules maintain their 2666MHz data rate under continuous multi-tasking loads. The quad-channel population fills four slots on compatible boards, allowing the memory controller to interleave requests and keep throughput steady during extended sessions.

Build and Daily Implications

Each module uses major-brand DRAM ICs without a heat spreader, keeping the profile low for tight chassis clearances. The 260-pin edge connector follows the DDR4 SODIMM standard, so installation is a simple press-in action. Verify your system's maximum supported capacity and slot count before purchase, as not every mobile platform can address the full 64GB.

Questions about this item

How much power does the 1.20 V DDR4 2666 kit draw when the laptop runs all day?

The modules operate at the standard DDR4 voltage of 1.20 V, keeping power draw low during continuous use.

What must my notebook already provide for this 260-pin quad-channel kit to function?

Your system needs four free DDR4 SO-DIMM slots that accept 260-pin unbuffered non-ECC memory at 2666 MHz.

Will the CL19 timing work reliably with other DDR4 SODIMMs I leave installed?

The kit runs at CL19; mixing modules with different latencies may force the slowest timing across all slots.
