16GB DDR4 2666MHz SODIMM

This 16GB DDR4 SO-DIMM module runs at 2666MHz with CL19 latency and 1.2V operation. It uses a 260-pin form factor and unbuffered non-ECC architecture. Major brand chips are used throughout for dependable laptop memory upgrades.

Suits standard laptop upgrades.

The module fits mainstream AMD and Intel laptop platforms that accept DDR4 2666MHz SO-DIMM memory. Systems requiring ECC, registered, or buffered memory cannot use this kit. Buyers needing higher frequencies or lower latencies should look elsewhere.

16GB single-module capacity for multitasking

One 16GB stick provides ample space for everyday workloads, multiple browser tabs, and light content creation. The single-module design leaves a second slot free for future expansion where the chassis allows. Heavy virtualisation or large dataset work may still exceed this capacity.

Questions about this item

My laptop only has one SODIMM slot — will this single 16 GB module work on its own?

Yes, the module is a single 16 GB stick so it will run in a lone slot without needing a matched pair.

I am keeping my original 8 GB 2666 MHz stick — will both run at the same speed?

The system will clock both modules to the lowest common speed; since each is rated at 2666 MHz they will operate together at that frequency.

How can I confirm the new RAM is detected at 2666 MHz after installation?

Open Task Manager, go to the Performance tab, select Memory and verify the speed reads 2666 MHz and the total capacity shows the expected amount.
