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.

Preguntas sobre este artículo

What does the DDR4 2666 (PC4-21300) interface mean for real-world speed?

The module runs at 2666 MT/s with CL19 timing, so the DDR4 2666 interface sets the maximum data rate the memory controller can use.

Will the 260-pin SO-DIMM fit my laptop slot?

This is a 260-pin DDR4 SO-DIMM; it fits standard laptop DDR4 slots that accept 260-pin modules.

How do I install it and what step do people miss?

Power off, unplug, open the panel, align the notch on the 260-pin edge connector, press firmly until the side clips click — the step often missed is pressing hard enough to seat both clips.
