ThinkPad W520 2GB DDR3 SODIMM

This 2GB DDR3 SODIMM is built specifically for the Lenovo ThinkPad W520. It runs at 1333MHz with CL9 latency and operates at 1.5V using an unbuffered non-ECC design. The 204-pin module installs directly into the laptop memory slot.

Suits single-slot upgrades on W520

Owners needing a single 2GB module to fill one slot will find this part matches the factory specification. Users who require higher total capacity or dual-channel kits should look at other options. Systems outside the W520 platform are not supported by this validated part number.

2GB capacity sets the limit

The module provides exactly 2GB of memory, which determines the maximum amount this stick can add. Buyers needing 4GB or 8GB per slot must choose a different capacity module. The 1Rx8 rank and PC3-10600 speed rating are fixed by this specification.
