1GB DDR1 SO-DIMM for ThinkPad T30

This 1GB DDR1 266MHz module uses the 200-pin SO-DIMM form factor. It is built for IBM Lenovo ThinkPad T30 notebooks and operates at 2.5V with CL2.5 timing. The kit contains a single unbuffered, non-ECC stick.

Suits T30 owners adding memory within the 2GB limit

Buyers upgrading a ThinkPad T30 can use this module to reach the system maximum of 2GB across two sockets. It is not suited for laptops that require a different pin count, voltage, or memory generation.

200-pin DDR1 interface and 2.5V operation

The module conforms to the PC2100 DDR1-266 standard with 200 pins and 2.5V supply. Verify that the target notebook accepts 200-pin DDR1 SO-DIMMs at this voltage before purchase.

Questions about this item

Will this 200-Pin DDR1 266MHz SO-DIMM work alongside the original module in my ThinkPad T30?

This module is specified as compatible with the ThinkPad T30 series and uses the same DDR1 266MHz PC2100 standard, so it will operate correctly with the factory-installed memory.

How can I confirm the 1GB DDR1 266MHz stick is running at the correct speed after installation?

Check the BIOS memory information or a system tool such as CPU-Z; both should report DDR 266 (PC2100) with CL2.5 timings.

Does the package include only the CM128642100SO module or are any tools or adapters supplied?

The box contains one 200-Pin DDR SO-DIMM memory stick; no tools, adapters or additional components are included.
