A-Tech 4GB DDR4 2666MHz CL19 1.2V SODIMM laptop RAM

4GB DDR4 2666 SODIMM laptop upgrade

This A-Tech module delivers 4GB of DDR4 memory at 2666MHz with CL19 latency and 1.20V operation. The 260-pin SO-DIMM form factor fits standard laptop, notebook and all-in-one sockets. It is an unbuffered, non-ECC replacement matched to the Micron MTA8ATF51264HZ-2G6B1 part number.

For single-slot capacity boosts.

Buyers adding a single 4GB stick to an empty slot or replacing a failed module will find this a direct fit. Systems that require ECC registered memory or need higher densities per slot should look elsewhere, as this module is non-ECC unbuffered and limited to 4GB.

CL19 latency at DDR4 2666 speed

The CAS latency of 19 cycles at 2666MHz determines how quickly the memory responds to read requests. Matching this timing to your platform's supported speed is the key factor in deciding if this module will run at its rated performance.
