16GB DDR4 SODIMM for laptop upgrades

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

Micron part-number compatibility

The module is built to match Micron part numbers MTA16ATF2G64HZ-2G6, MTA16ATF2G64HZ-2G6E1 and MTA16ATF2G64HZ-2G6H1. This equivalence lets owners of those specific factory configurations install a verified alternative without changing BIOS settings or voltage profiles.

260-pin SO-DIMM build and voltage

The stick follows the 260-pin DDR4 SO-DIMM standard and runs at the DDR4 default of 1.2V. Its unbuffered layout fits the memory slots found in compatible notebooks and all-in-one PCs, allowing a straightforward module swap during a memory upgrade.

Questions about this item

Will the 16GB DDR4 SODIMM need any firmware updates or component replacements during its service life?

No firmware updates or component replacements are required; the 1.2V unbuffered DDR4 module is a solid-state part with no moving or programmable elements that wear out.

What limit appears first when the 2666MHz CL19 module runs at full load for extended periods?

The JEDEC-standard 1.20V voltage ceiling is reached before thermal or timing limits, so sustained throughput is capped by the rated DDR4 2666 speed.

How much heat and noise does the 260-pin 16GB stick produce inside a laptop chassis all day?

The module runs silently with no fan; at 1.2V it adds only modest warmth that the laptop's existing cooling handles without extra noise.
