2GB DDR3 1066 SO-DIMM for Lenovo ThinkPad X120e

This 2GB DDR3 1066 SO-DIMM module is built for the Lenovo ThinkPad X120e series, matching the 0596 and 0611 model codes. It runs at PC3 8500 speed with CL7 timing at 1.5V. The unbuffered, non-ECC stick uses a 1Rx8 rank layout with major brand chips. It adds 2GB to one of the two available sockets.

Simple 204-pin SO-DIMM installation

Installation follows the standard 204-pin SO-DIMM process for the ThinkPad X120e. Align the notch, insert at an angle, then press down until the side clips engage. The module has no heat spreader, so it fits tight bays without clearance issues. Common problems include mixing speeds across sockets or exceeding the 3GB limit on a 32-bit OS, which the system cannot address.

Suits X120e owners needing a single 2GB stick

This module suits owners of a Lenovo ThinkPad X120e who want to populate one slot with a compatible 2GB DDR3 1066 stick. It is not for systems that require ECC or registered memory, nor for laptops using a different pin count or voltage. Buyers needing more than 4GB total capacity or a different DDR generation should look elsewhere.

Questions about this item

How can I confirm the CL7 timing is active after installing the CM256648500SO module?

Open the BIOS or a system-information utility and verify the memory runs at 1066 MHz with 7-7-7 timings at 1.5 V.

What does the package contain and is anything else required for installation?

The box includes one 2 GB 204-pin DDR3 SO-DIMM; no extra parts or tools are needed to fit it into the ThinkPad X120e.

Which capacity should I choose if my X120e runs a 32-bit operating system?

A 32-bit OS on this model supports up to 3 GB total, so a single 2 GB stick leaves room for another module later.
