System-Specific DDR3 Upgrade

This 2GB DDR3 SODIMM is built for owners of Lenovo ThinkPad T400, T400s, T410i, T410s, T410si, T500 and T510i laptops who need a single-module memory increase. It matches the factory DDR3 1066 specification so the system recognises it without configuration changes.

Standard 204-Pin SODIMM Build

The unbuffered, non-ECC module uses a 1Rx8 layout and runs at the JEDEC-standard 1.5V, fitting directly into the laptop's 204-pin slot without a heat spreader. RoHS compliance and OWC's in-house testing mean the stick meets OEM electrical and physical tolerances for a warranty-safe installation.

2GB Single-Module Capacity

The upgrade adds exactly 2GB of PC3-8500 CL7 memory in one slot, which suits systems limited to lower-density modules or users replacing a single failed stick. Buyers needing higher total memory or dual-channel kits should look for larger-capacity or matched-pair alternatives.
