4GB DDR3 SO-DIMM for Laptop Upgrade

This 4GB DDR3 1333MHz module uses the 204-pin SO-DIMM form factor and runs at the standard 1.5V voltage. It is built as a direct replacement for several Micron part numbers including MT16JSF51264HZ-1G4 and MT16JTF51264HZ-1G4M1. The CL9 latency and unbuffered, non-ECC design suit mainstream laptop and all-in-one systems.

Fits Standard DDR3 Laptop Slots

The module installs into any 204-pin DDR3 SO-DIMM socket that accepts 1.5V PC3-10600 memory. It requires no extra power connectors or cooling and leaves the second slot free if your system supports dual-channel operation. Verify your platform's maximum supported capacity and slot count before purchase to ensure the upgrade matches the hardware limits.

Steady Throughput at CL9 Timings

Under sustained workloads the stick maintains its rated 1333MHz speed and CL9 latency without throttling, thanks to standard-voltage operation and quality-assurance testing. The 2Rx8 organisation delivers consistent bandwidth for multitasking and heavier data sets. Systems limited to lower memory speeds will down-clock the module automatically, preserving stability over peak burst performance.

Questions about this item

What limits the A-Tech 4GB DDR3 1333MHz module under sustained use?

The CL9 CAS latency and 1.5V voltage set the timing and power ceiling during continuous operation.

How does the 204-pin SO-DIMM behave for noise, heat and power when running all day?

It runs silently with no moving parts, draws 1.5V standard DDR3 power, and produces low heat typical for a 4GB unbuffered module.

What does the buyer need to already own for this 204-pin DDR3 1333MHz stick to work?

A laptop or all-in-one with a DDR3 SO-DIMM slot that accepts PC3-10600 1.5V non-ECC unbuffered memory.
