16GB DDR4 2666MHz SODIMM

This 16GB DDR4 module runs at 2666MHz with CL19 latency and 1.20V operation. The 260-pin SO-DIMM form factor fits standard laptop memory slots. It uses an unbuffered, non-ECC design built with (1G x 8) x 16 components.

Laptop upgrades needing a single 16GB stick

Suits owners adding or replacing memory in a notebook that accepts DDR4 SO-DIMMs at this speed and voltage. Not for systems limited to 8GB maximum capacity, boards requiring ECC or registered modules, or desktops needing full-size DIMMs.

Speed rated at PC4-21300 2666MHz

The module is specified at DDR4 2666 (PC4-21300), so the memory controller must support that data rate for full performance. If the platform caps memory at a lower frequency, the stick will down-clock automatically.

Questions about this item

Will the 260-pin SODIMM fit my laptop's DDR4 slot?

Yes, the 260-pin DDR4 SO-DIMM form factor matches standard laptop DDR4 slots.

What is the correct way to seat the module so the contacts make full connection?

Align the notch with the slot key, insert at a 30-degree angle, then press down firmly until both side clips click into the notches.

When should I consider replacing this 16GB DDR4 2666MHz module?

Replace it if you encounter repeated memory errors, if your workload consistently exceeds 16GB, or if a future platform requires a newer DDR generation.
