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.

Questions about this item

How much power does this 1.2V DDR4 3200MHz SODIMM draw during continuous all-day operation?

It runs at the standard DDR4 voltage of 1.2V, keeping power draw low and heat minimal for sustained laptop use.

What must my laptop already have to accept this 260-pin DDR4 SO-DIMM module?

Your laptop needs a free DDR4 SO-DIMM slot that supports 3200MHz PC4-25600 unbuffered non-ECC memory at 1.2V.

Will this CL22 3200MHz stick work alongside my existing slower DDR4 SODIMMs?

Yes, it will downclock automatically to match the speed and latency of the installed modules for stable operation.
