Targeted upgrade for Lenovo ThinkPad X131E AMD

This 4 GB DDR3L SO-DIMM is built specifically for the Lenovo ThinkPad X131E AMD models 3371-xxx and 3372-xxx. It installs into one of the two available memory slots to raise the total capacity toward the 8 GB maximum. The module is unbuffered, non-ECC and carries a CL11 11-11-11 timing at 1600 MHz.

Low-voltage 204-pin stick with no heat spreader

The 204-pin form factor fits the standard SO-DIMM socket found in the target notebooks. Operating at 1.35 V, the DDR3L module draws less power than conventional DDR3, helping battery life run longer. A major-brand chipset is used on the PCB, and the absence of a heat spreader keeps the profile thin for tight chassis clearance.

Single-module kit backed by CMS lifetime warranty

The package contains one 4 GB stick, letting you add memory incrementally or replace a failed module. Computer Memory Solutions guarantees compatibility with the listed ThinkPad models and provides a limited lifetime warranty when purchased directly from CMS. Product appearance may vary from the reference photograph.
