8GB DDR4 2666 SODIMM for laptops

This 8GB DDR4 2666 CL19 SODIMM upgrades memory in laptops, all-in-one PCs, small-form-factor desktops and NAS appliances. It runs at 1.20V and uses the standard 260-pin DDR4 SO-DIMM form factor. The module is unbuffered and non-ECC, matching the requirements of most consumer and small-business platforms. Buyers who need ECC or registered memory for enterprise servers should choose a different module.

Tool-free slot installation in minutes

Installation typically takes a couple of minutes by opening the memory compartment and pressing the module into the slot until the clips engage. The low-profile design has no heat spreader, so it fits tight chassis without clearance issues. The most common mistake is inserting the module at the wrong angle or not seating it fully, which prevents the system from booting. Always consult the device manual for the exact slot location and maximum supported capacity.

2666 MT/s CL19 speed rating

The module operates at DDR4 2666 (PC4-21300) with a CAS latency of 19. This speed and timing combination determines whether the memory matches the platform's supported specification. If the system requires a different data rate or lower latency, this module may not run at its rated performance or may be incompatible.

Questions about this item

How do I confirm the module is running at 2666 MHz with CL19 timings after installation?

Open Task Manager or a hardware monitor such as CPU-Z and check that the memory frequency reads 2666 MHz and the CAS latency shows 19.

What comes in the package and is anything else required for installation?

The box contains a single 8 GB 260-pin DDR4 SODIMM module; no extra parts or tools are needed beyond a compatible laptop slot.

Which version should I choose if my system needs PC4-21300 speed and 1.20 V operation?

Select the 8 GB DDR4 2666 CL19 1.20 V SODIMM (part number MS21300-818K1) — it matches that exact speed and voltage.
