A-Tech 4GB DDR4 3200MHz SODIMM CL22 1.2V laptop RAM

4GB DDR4 3200 SODIMM for laptop upgrades

This 4 GB DDR4 module runs at 3200 MHz with CL22 latency and 1.2 V operation. It uses the 260-pin SO-DIMM form factor and is unbuffered non-ECC. The stick is a direct replacement for Micron MTA4ATF51264HZ-3G2 family parts and suits AMD and Intel platforms that accept DDR4 SO-DIMMs.

Sustained load behaviour at CL22 1.2 V

At standard voltage the module maintains its rated 3200 MHz transfer rate during extended workloads. CL22 timing stays consistent without requiring extra cooling or voltage headroom. The single-rank 1Rx16 organisation keeps power draw low so thermals remain stable in thin-and-light chassis under continuous multitasking.

Build quality and daily connector implications

Each unit undergoes quality-assurance testing before shipment and carries a lifetime warranty from A-Tech. The 260-pin edge connector keys into standard DDR4 SO-DIMM slots with a firm click, reducing reseats. Unbuffered non-ECC design means no extra register chips to fail, so the module slides in and stays reliable through repeated upgrade cycles.
