Compatible Lenovo ThinkPad R61i memory

This 2 GB DDR2 SO-DIMM is built for the Lenovo ThinkPad R61i models 8932 and 8943‑xxx. It uses the 200‑pin DDR2 667 MHz (PC2‑5300) standard with CL5 timing and runs at 1.8 V. The module is unbuffered, non‑ECC and organised as 2Rx8 with major‑brand chips.

Suits owners of those specific ThinkPad models

The stick matches the factory‑listed slot count and maximum memory ceiling for the named laptops. Buyers who need more than 2 GB per module, who require ECC or registered memory, or who are upgrading a different notebook or a desktop system should look elsewhere.

Deciding specification: DDR2 667 MHz 200‑pin SO-DIMM

Only systems that accept DDR2 667 MHz (PC2‑5300) 200‑pin SO-DIMMs can use this module. Verify the laptop’s memory generation and pin count before ordering, because a different DDR generation or pin layout will not fit.

Questions about this item

Will this 200-pin DDR2 667 MHz SO-DIMM work in the second slot of my Lenovo ThinkPad R61i 8932 alongside an existing module?

Yes, the R61i 8932 has two SO-DIMM sockets and supports a maximum of 4 GB, so adding this 2 GB stick in the free slot is fully compatible.

How can I verify the CL5 timing and 1.8 V voltage are applied correctly after installation?

Open the BIOS or a system-information utility such as CPU-Z; the memory tab should report DDR2-667, CL5-5-5 timings and 1.8 V operation.

Does the package contain only the CM256645300SO module or are any tools or adapters included?

The box contains one 2 GB 200-pin DDR2 SO-DIMM and nothing else; no screwdriver, adapter or extra components are supplied.
