16GB DDR4 2666MHz SODIMM Module

This 16GB DDR4 2666MHz CL19 SODIMM is a laptop memory upgrade built to the PC4-21300 standard. It uses a 260-pin form factor and operates at the standard 1.20V voltage. The unbuffered, non-ECC module is designed for AMD and Intel compatible notebook and all-in-one systems.

Suitable for single-slot 16GB upgrades

Buyers needing a matched pair for dual-channel operation or a total capacity above 16GB should look elsewhere. Systems limited to lower DDR4 speeds or requiring ECC registered modules will not be compatible with this specific part.

260-pin DDR4 SO-DIMM form factor decides fit

The module only installs in slots keyed for 260-pin DDR4 SO-DIMMs. Verify your system accepts this exact pin count and DDR4 generation before ordering, as other memory types are physically incompatible.

Questions about this item

How can I confirm the module is running at 2666 MHz with CL19 timing after installation?

Open Task Manager or CPU-Z and check the memory tab; it should show 2666 MHz speed and CAS latency 19.

Does the package contain only the 16 GB SODIMM or are tools or adapters included?

The box holds a single 260-pin DDR4 SO-DIMM; no tools, adapters or extra cables are supplied.

Should I choose the 16 GB CL19 version or a different capacity for my laptop?

This listing is a single 16 GB module at CL19; select it if your system supports one 16 GB stick at 2666 MHz.
