Panasonic Toughbook CF-29M DDR2 SODIMM Upgrade

This 1 GB 200-pin DDR2 SODIMM runs at 533 MHz (PC2 4200) with CL4 timings and 1.8 V operation. It is built for the Panasonic Toughbook CF-29M notebook series and similar DDR2 models such as CF-29N and CF-29P. The unbuffered, non-ECC module uses major-brand chips in a 2Rx8 configuration.

Replaces the single user-accessible slot on DDR2

These machines ship with 512 MB soldered and one open socket; this stick fills that socket to reach the 1.5 GB maximum. The jump is worth it when the system still runs DDR2 and the workload needs more than the base 512 MB. Buyers with the ddr1 version of the same chassis cannot use this module and must seek the correct generation instead.

Limited by the DDR2 SO-DIMM interface

The 200-pin DDR2 standard tops out at 533 MHz here, and the chipset caps total memory at 1.5 GB. No further expansion is possible beyond the single upgrade socket. The module has no heat spreader and carries a lifetime warranty from Computer Memory Solutions when purchased directly from the manufacturer.

What is the correct way to seat the module in the CF-29M slot?

Slide the module into the socket until the gold contacts are fully hidden, then press down evenly until the retention clips snap into the side notches.

Does this DDR2-533 CL4 module require any future maintenance or replacement?

No — it has no heat spreader, no moving parts, and carries a limited lifetime warranty from Computer Memory Solutions.
