Compatible ThinkPad Upgrade

This 4GB DDR3 SODIMM is built for specific Lenovo ThinkPad models including the W500, W700, W700ds, X201, X201i and X201s. It targets owners of these mobile workstations and ultraportables who need a direct-replacement module to restore or expand system memory. Buyers with other laptop lines or desktop platforms cannot use this 204-pin form factor.

Speed And Latency Match

The module runs at 1066MHz with a PC3-8500 rating and CL7 latency at 1.5V. These three figures must match the existing memory or the system specification; a different speed grade or voltage will prevent the laptop from posting. The 2Rx8 rank organisation is also fixed by the platform design.

Single Slot Installation

The unbuffered non-ECC stick fits a single 204-pin SODIMM socket inside the supported ThinkPad chassis. No heat spreader is fitted, keeping the profile low for tight keyboard-deck clearances. Installing this unit occupies one slot and leaves any second socket free for a matching module if the model provides dual-channel capability.
