8GB DDR4 2666MHz SODIMM for Laptop Upgrade

This 8GB module uses DDR4 technology at 2666MHz with CL19 latency and 1.20V operation. It fits 260-pin SO-DIMM slots in compatible laptops, notebooks and all-in-one systems. The unbuffered, non-ECC design suits mainstream consumer platforms from AMD and Intel. Major-brand chips are tested for dependable performance.

Capacity and headroom for everyday multitasking

A single 8GB stick provides comfortable headroom for web browsing, office suites and media playback. Light creative workloads such as photo editing run without constant swapping. Heavy multitasking with many browser tabs, virtual machines or large datasets will exceed the available memory and force reliance on slower storage.

Standard SO-DIMM build with broad slot compatibility

The 260-pin form factor matches the physical and electrical specification for DDR4 laptop slots. Gold contacts resist oxidation and ensure reliable seating during installation. No heatsink or tall components interfere with tight chassis clearances. The module installs in minutes with a screwdriver and requires no software configuration.

Questions about this item

Will this DDR4 2666MHz CL19 module run alongside my existing DDR4 SODIMM without issues?

This module operates at DDR4 2666MHz with CL19 latency and 1.20V voltage. When mixed with another DDR4 SODIMM, the system will run both at the speed and timings of the slower stick. Verify your laptop supports DDR4 SO-DIMM before installing.

How can I confirm the 260-pin DDR4 2666MHz stick is detected and running at the correct speed after installation?

Open Task Manager or your BIOS/UEFI after boot. The memory tab should show 8GB capacity, DDR4 type, 2666MHz speed, and 260-pin form factor. CPU-Z or similar tools will also report the CL19 timing and 1.20V operating voltage.

Does the package contain only the single 8GB SODIMM, or are tools or additional parts included?

The box contains one 8GB DDR4 2666MHz CL19 260-pin SODIMM module. No screwdriver, anti-static strap, or extra components are supplied. You may need a small Phillips screwdriver to open your laptop's memory compartment.
