Speed DDR4 2666 (PC4 21300)

CAS Latency CL19

  • Boosts system responsiveness with 2666 MHz DDR4 speed
  • Low 1.2 V operation reduces laptop power draw
  • CL19 latency supports smooth multitasking performance
  • 260-pin SO-DIMM fits standard DDR4 laptop slots
  • Rigorously tested for reliable operation in notebooks

4GB DDR4 SODIMM for Laptops

This module adds four gigabytes of DDR4 memory to compatible laptops, notebooks and all-in-one PCs. It uses the 260-pin SO-DIMM form factor and runs at the standard 1.2V voltage. The kit suits users who need a straightforward capacity increase for everyday workloads.

DDR4 2666 speed ceiling

The stick operates at DDR4 2666 (PC4-21300) with a CAS latency of CL19. Systems that only support lower DDR4 speeds will down-clock the module automatically. Platforms requiring ECC or registered memory cannot use this unbuffered non-ECC design.

Single 4GB module constraint

Only one 4GB rank is provided, so total capacity rises by exactly that amount. Buyers whose chassis have a single SODIMM slot or whose workloads demand more than four gigabytes should verify slot count and required capacity before ordering.
