16 GB DDR4 2666 laptop kit

This SK hynix kit provides 16 GB of DDR4 memory in two 8 GB SODIMM modules. It runs at 2666 MT/s with CL19 latency and operates at the standard 1.20 V for DDR4. The unbuffered, non-ECC design matches typical laptop requirements.

Who this suits and who it does not

The dual-channel pair suits owners of DDR4 laptops that accept 260-pin SODIMMs and need 16 GB total capacity. It is not for systems limited to single modules, machines that require ECC or registered memory, or platforms that use a different DDR generation.

What to verify before ordering

Confirm your laptop uses DDR4 SO-DIMM slots with a 260-pin interface and supports 2666 MT/s operation. Check the maximum memory per slot and total capacity allowed by the manufacturer. Ensure the BIOS can run modules at 1.20 V without manual voltage adjustment.
