2GB DDR3 1066MHz SODIMM for Lenovo T400

This 2GB DDR3 1066MHz CL7 SODIMM module is built for upgrading Lenovo ThinkPad T400 and T400s notebooks. It runs at PC3-8500 speed with 1.5V unbuffered operation and carries a 2Rx8 rank configuration using major-brand chips.

Suits T400 owners adding one stick.

The module is validated for the listed ThinkPad T400 and T400s model numbers only. It will not fit systems that require a different pin count, voltage, or form factor, nor will it work in desktops or servers needing ECC or registered memory.

204-pin DDR3 SO-DIMM interface decides fit

The 204-pin DDR3 SO-DIMM interface is the single specification that determines compatibility. If the target laptop accepts 204-pin DDR3 SODIMMs at 1066MHz, this stick will install; otherwise it cannot be used.

Questions about this item

Does my Lenovo ThinkPad T400 or T400s have an available 204-pin DDR3 SO-DIMM slot for this module?

The T400 and T400s series use DDR3 SO-DIMM slots; verify your specific model (e.g., 2764, 2801, 6473, 7417) has a free slot before installing this 204-pin stick.

Will this PC3-8500 CL7 1.5V module run correctly alongside any existing DDR3 1066 MHz memory already in my ThinkPad?

Yes, it matches the DDR3 1066 MHz speed, CL7 timing and 1.5 V voltage used in these ThinkPads; the system will clock all modules to the slowest common settings.

How can I confirm the 2 GB module is recognised at 1066 MHz with CL7 timings after installation?

Enter BIOS or use a system-information tool such as CPU-Z; the memory tab should show 2 GB, DDR3-1066 (PC3-8500) and 7-7-7 timings.
