16GB DDR4 2666MHz SODIMM Upgrade

This 16GB DDR4 SODIMM module operates at 2666MHz with CL19 latency and 1.20V voltage. It uses a 260-pin unbuffered non-ECC design built with major brand chips for laptop memory upgrades.

Suits owners of compatible Kingston referenced

Buyers needing ECC error correction or registered buffered modules should look elsewhere. Systems limited to lower maximum capacities or different pin counts cannot use this module.

Single 16GB module for mainstream workloads

The 16GB capacity handles everyday multitasking and typical productivity applications comfortably. Workloads requiring larger memory arrays beyond a single module will need additional slots or higher density options.

Questions about this item

Does this 260-pin DDR4 SODIMM need a laptop that accepts 1.2 V DDR4 2666 modules?

Yes — the module is a 260-pin DDR4 SODIMM rated at 2666 MHz, PC4-21300, 1.20 V, unbuffered non-ECC, so the laptop must support that exact DDR4 specification.

If I keep an older DDR4 stick in the second slot, will the system still boot at the lower common speed?

The module runs at 2666 MHz CL19; when paired with slower DDR4 the memory controller typically downclocks both sticks to the lowest common frequency and loosest timings.

How can I confirm the new 16 GB module is detected and running at 2666 MHz after installation?

Open Task Manager’s Performance tab or run a system-information tool such as CPU-Z; it should show 16 GB, DDR4, 2666 MHz, and the correct 260-pin SODIMM form factor.
