4GB DDR3L SODIMM for Laptop Upgrade

This single 4GB module uses 204-Pin DDR3L technology at 1600MHz with a low 1.35V operating voltage. It is built for laptops, notebooks and all-in-one systems that require PC3L-12800 unbuffered non-ECC memory.

Low-Voltage Build for Compatible Slots

The DDR3L design runs at 1.35V instead of the standard 1.5V, reducing power draw and heat in supported platforms. Its 204-pin SO-DIMM form factor fits the standard DDR3 laptop slot, while the CL11 latency and 1Rx8 organisation match the timing requirements of many AMD and Intel systems.

Tested Module with Lifetime Coverage

Each stick undergoes quality assurance testing before shipping to verify reliable operation. The package includes only the memory module itself; no additional cables, tools or software discs are supplied. Buyers who need higher capacities or multiple modules for dual-channel configurations should look elsewhere.

Questions about this item

What speed does the DDR3L 1600 (PC3L-12800) interface actually run at?

The module is rated for 1600 MHz and will operate at that speed if the platform supports it; otherwise it downclocks to the highest speed the system allows.

What physical slot and notch position does this 204-pin SODIMM need?

It requires a standard DDR3 204-pin SO-DIMM slot; the notch is offset from centre so it only fits one way.

How is the module seated, and which step do people often miss?

Slide the stick into the slot at an angle until the contacts are fully hidden, then press down evenly until both retention clips snap into the side notches.
