16GB DDR4 2666 SODIMM

This 16GB DDR4 2666 SODIMM module delivers 16GB of memory at 2666MHz with CL19 latency. It uses a 260-pin SO-DIMM form factor and operates at the standard 1.2V DDR4 voltage. The unbuffered, non-ECC design suits mainstream laptop and all-in-one systems.

Upgrade for compatible Lenovo notebooks

It suits owners of compatible Lenovo laptops needing a single 16GB module to increase capacity. Buyers whose systems require ECC, registered DIMMs, or a different pin count should look elsewhere. Verify your device supports DDR4 2666 SO-DIMM before ordering.

Fits DDR4 SO-DIMM slots

The module installs directly into a standard DDR4 260-pin SO-DIMM slot without extra cables or power connections. It frees the system to handle heavier multitasking and larger workloads. Confirm the maximum supported capacity and slot count of your platform before installation.

Questions about this item

My laptop has one free SODIMM slot — is the 260-pin DDR4 2666 module the only part I need to install?

Yes, the 260-pin DDR4 2666 SODIMM is a complete module; insert it into the empty slot and secure the retaining clips.

I want to keep my original Lenovo 01AG819 8 GB stick and add this 16 GB module — will they work together?

Both are DDR4 2666 SODIMMs, so the system will run them in dual-channel mode at the shared 2666 MT/s speed.

After fitting the module, how can I confirm it is running at the rated 2666 MT/s CL19?

Open Task Manager → Performance → Memory or run CPU-Z; both will show 2666 MT/s and CL19 timings.
