8GB DDR4 2666MHz SODIMM for laptop upgrades

This 8GB DDR4 2666MHz CL19 module uses the 260-pin SO-DIMM form factor and operates at 1.20V. It is built with major brand chips and is an unbuffered non-ECC part. The stick is tested for reliability and serves as a direct replacement for Kingston KCP426SS6/8 and KVR26S19S6/8 modules.

Fits DDR4 2666MHz laptop slots only

This upgrade suits owners of compatible laptops, notebooks or all-in-one systems that support DDR4 2666MHz SO-DIMM memory. Buyers whose devices require a different DDR generation, a different pin count, ECC or registered modules, or speeds other than 2666MHz should look elsewhere.

Speed and form factor decide fit

The single specification that determines compatibility is the DDR4 2666MHz (PC4-21300) 260-pin SO-DIMM standard. Verify that your system accepts this exact speed and form factor before ordering.

Questions about this item

My laptop only has a single DDR4 SO-DIMM slot — will this 8GB 2666MHz module work as the only stick?

Yes, the module is a single 8GB 260-pin DDR4 SO-DIMM rated at 2666MHz CL19 1.20V, so it will operate alone in a compatible slot.

I want to keep my current 8GB DDR4 2666MHz CL19 stick and add this one — will they run together at the rated speed?

Both modules share the same 2666MHz CL19 1.20V specification, so a paired installation should run at the rated speed if the platform supports dual-channel operation.

After installing the SODIMM, how can I confirm it is running at 2666MHz CL19?

Open Task Manager or CPU-Z and check the memory tab; it should show 2666MHz and a CAS latency of 19 for the new module.
