Compatible 4GB DDR4 SODIMM for Micron systems

This module replaces Micron MTA4ATF51264HZ-2G3E1 in laptops, notebooks and all-in-one computers. It adds 4GB of DDR4 memory to systems that accept 260-pin SO-DIMMs. Buyers who need more capacity or dual-channel kits should look elsewhere.

260-pin unbuffered design at 1.2V

The stick uses standard DDR4 voltage and requires no heat spreader, fitting slim chassis without clearance issues. Non-ECC, unbuffered operation matches the original Micron specification for drop-in installation.
