ThinkPad X201 memory upgrade

This 8 GB kit supplies two 4 GB DDR3 SODIMM modules built for Lenovo ThinkPad X201 models 3249, 3626 and 3680. It targets owners who need the maximum 8 GB capacity these laptops accept and want a matched pair for dual-channel operation.

204-pin unbuffered non-ECC sticks

Each module runs at 1066 MHz with CL7 7-7-7 timings at 1.5 V using major-brand 2Rx8 chips. The standard SO-DIMM keying fits the two factory slots directly, and the lack of a heat spreader keeps the profile low enough for the X201's tight chassis clearance.

Two-module kit only

The package contains exactly two SODIMMs and no software, adapters or tools. Installation is a simple slot swap, but buyers who need a single 8 GB stick, ECC support or speeds above PC3-8500 must look elsewhere.

Questions about this item

Does the DDR3 1066 MHz speed cap the maximum bandwidth on the ThinkPad X201?

The modules run at PC3-8500 DDR3-1066 with CL7 timing, matching the X201 memory controller specification.

Will the 204-pin SODIMM sticks fit the two memory slots in the X201?

Each stick is a standard 204-pin DDR3 SODIMM and the kit provides two modules for the two available sockets.

What is the correct order for installing the two 4 GB modules in the X201?

Insert both modules firmly into the two slots until the side clips click; the kit is a matched pair so either slot order works.
