16GB DDR4 2666MHz SODIMM Laptop RAM

This 16GB DDR4 2666MHz CL19 module uses the 260-pin SO-DIMM form factor and operates at the standard 1.20V. It is an unbuffered, non-ECC memory upgrade designed for laptops, notebooks, and all-in-one computers. The module serves as a compatible replacement for the Crucial CB16GS2666 part number.

Suits owners of DDR4 laptops needing 16GB at 2666MHz

Buyers whose systems require ECC memory, registered modules, or a different DDR generation cannot use this stick. Builders needing multiple modules for a multi-channel configuration should verify slot count before ordering a single unit. Systems limited to lower voltage standards will not be compatible.

260-pin DDR4 SO-DIMM interface

The 260-pin DDR4 SO-DIMM interface is the single specification that determines physical and electrical compatibility with the laptop memory slot. Verify that the target system supports DDR4 SO-DIMM memory before purchase.
