System-specific DDR2 SO-DIMM for ThinkPad R61i

This 2 GB DDR2 667 MHz module is built for Lenovo ThinkPad R61i models 7650, 7732 and 7742-xxx. It uses a 200-pin SO-DIMM form factor and runs at 1.8 V with CL5 timing. The unbuffered, non-ECC design matches the original factory specification for these notebooks.

Suitable for owners restoring

The single 2 GB stick fills one of the two available slots and works within the 4 GB maximum memory limit. Buyers who need more than 4 GB total capacity or who are repairing a different laptop family should look elsewhere because this module is validated only for the named systems.

DDR2 667 (PC2 5300) speed grade decides fit

The notebook’s memory controller requires the 667 MHz data rate and 5-5-5 latency cycle; a faster or slower DDR2 module will not operate correctly. Verify the existing memory runs at this exact speed before ordering to avoid a mismatch.

Questions about this item

Will the 200-pin DDR2 SODIMM fit the memory slots in my ThinkPad R61i 7650?

Yes, the module is a 200-pin DDR2 SO-DIMM designed for the R61i 7650, 7732 and 7742-xxx models that accept PC2 5300 memory.

How do I install the SODIMM and what step do people often miss?

Power off the laptop, remove the battery, open the memory cover, insert the stick at an angle until the gold contacts disappear, then press down until both side clips click — the click is the step many forget.

When will this 2GB DDR2 module need to be replaced?

DDR2 memory has no moving parts and requires no scheduled replacement; swap it only if a memory test reports errors or you upgrade to the system maximum of 4GB across the two sockets.
