A-Tech 8GB DDR4 2666MHz CL19 1.20V SODIMM Laptop RAM

8GB DDR4 2666MHz SODIMM for Laptop Upgrade

This 8GB DDR4 module runs at 2666MHz with CL19 latency and 1.20V operation. It uses the standard 260-pin SO-DIMM form factor for laptops, notebooks and all-in-one systems. The unbuffered, non-ECC design matches the Micron MTA8ATF1G64HZ series it replaces. It is suited to users adding capacity or swapping a failed stick in a compatible machine.

DDR4 SO-DIMM Speed and Voltage Constraints

DDR4 SO-DIMM slots accept this 2666MHz PC4-21300 module at its rated 1.20V. The memory controller in the host system determines the final operating speed; if the platform only supports a lower data rate the module will downclock automatically. CL19 timing is fixed for this part. Builders who need ECC, registered buffers or a different pin count cannot use this module.

Replaces Micron MTA8ATF1G64HZ Series Modules

This stick is a direct equivalent for Micron part numbers MTA8ATF1G64HZ-2G6B1, MTA8ATF1G64HZ-2G6E3 and MTA8ATF1G64HZ-2G6J1. The upgrade is worthwhile when the existing configuration has less than 8GB total or when a matching stick is required for dual-channel operation. Systems that already run at the maximum supported capacity or require a different DDR generation will not benefit.
