4GB DDR3L 1600 SO-DIMM laptop module

This VisionTek 900641 module provides 4GB of DDR3L memory rated at 1600 MHz (PC3L 12800). It uses a 204-pin SO-DIMM form factor and operates at 1.40V. The unbuffered, non-ECC design is built for standard laptop memory slots.

Suits owners of compatible DDR3L laptops needing

The module fits systems that accept DDR3L SO-DIMMs at 1.40V and 1600 MHz. It is not suitable for machines that require a different pin count, voltage, speed grade or form factor. Buyers who need larger capacity per slot or a multi-module kit should consider other options.

204-pin DDR3L SO-DIMM at 1.40V decides fit

The 204-pin DDR3L interface combined with 1.40V operation is the single specification that determines whether this module will install and run correctly. Verify that your laptop's memory slot and voltage requirements match these values before purchase.
