4GB DDR4 3200MHz SODIMM module

This 4GB DDR4 3200MHz CL22 SODIMM module is built as a compatible replacement for Micron MTA4ATF51264HZ-3G2R1. It uses a 260-pin DDR4 SO-DIMM form factor and runs at the standard 1.20V DDR4 voltage. The unbuffered, non-ECC design targets laptops, notebooks and all-in-one computers needing a straightforward memory upgrade.

Suits single-slot upgrades on DDR4 platforms

The single 4GB stick works for owners of DDR4 laptops with one free SO-DIMM slot who want a direct Micron equivalent. Systems that require ECC, registered modules, higher capacities per slot, or a different DDR generation will not accept this part.

260-pin DDR4 SO-DIMM interface decides fit

The 260-pin DDR4 SO-DIMM interface is the specification that determines whether the module fits and functions. Verify that your laptop supports DDR4 SO-DIMM memory before purchase.

Questions about this item

Should I choose the 4 GB module or look for a larger capacity?

This listing is a single 4 GB module running at 3200 MHz with CL22 latency; select it when your laptop has a free 260-pin DDR4 slot and 4 GB meets your workload.

What does the 3200 MHz rating mean once the module is installed?

The module operates at 3200 MT/s (PC4-25600 bandwidth) at 1.2 V; your laptop's memory controller will run it at the highest speed both the CPU and the module support.

Is this a 260-pin or 262-pin DDR4 SO-DIMM, and does the pin count affect compatibility?

The spec lists a 260-pin DDR4 SO-DIMM form factor; the 262-pin figure in some datasheets refers to the same mechanical keying, so the module fits standard DDR4 laptop slots.
