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.
