A-Tech 4GB DDR4 2666MHz SODIMM

This 4GB DDR4 module runs at 2666MHz with CL19 latency and 1.20V operation. The 260-pin SO-DIMM form factor fits standard laptop memory slots. It is an unbuffered, non-ECC stick built as a direct replacement for Samsung M471A5244BB0-CTD and M471A5244CB0-CTD modules.

Laptop owners needing a 4GB DDR4 upgrade

Users whose notebooks accept a single 260-pin DDR4 2666MHz SO-DIMM will find this module a straightforward drop-in. Systems that require ECC, registered memory, higher capacities per slot, or a different pin count should look at other options.

260-pin DDR4 SO-DIMM form factor

The 260-pin layout is the physical key that decides whether the stick seats in your laptop. Match this pin count and the DDR4 generation against your system manual before ordering.

Questions sur cet article

Does the 4GB DDR4 2666MHz SODIMM ship as a single stick or do I need to buy a second module?

The listing is for one 4GB module; add a second stick only if your laptop has a free slot and you want 8GB total.

Should I choose the CL19 1.2V version or look for a different latency kit?

This module runs at CL19 and 1.2V, the standard JEDEC timing for DDR4 2666; select it when your system requires that exact spec.

Will the 2666MHz rating actually run at that speed in my laptop?

It operates at DDR4 2666 (PC4-21300) provided the laptop’s memory controller supports that frequency; otherwise it down-clocks to the highest supported speed.
