Targeted DDR2 upgrade for Panasonic Toughbook 74 Mk3

This 2GB SODIMM module is built specifically for the Panasonic Toughbook 74 Mk3 series, including Cf-74, Cf-74J and Cf-74K models. It provides a direct memory enhancement for these legacy laptops without requiring configuration changes.

2GB capacity with 800MHz headroom

The single 2GB stick runs at DDR2 800 (PC2 6400) with CL6 6-6-6 timing at 1.8V. The Toughbook 74 Mk3 platform supports a maximum of 4GB across two sockets, so this module fills one slot and leaves room for a second identical stick to reach the system limit.

Unbuffered 200-pin SO-DIMM construction

The non-ECC, unbuffered 2Rx8 module uses major-brand chips on a standard 200-pin DDR2 SO-DIMM PCB with no heat spreader. It fits the Toughbook's internal memory bay directly, and the 1-piece kit delivers exactly one upgrade stick for immediate installation.

Questions about this item

Will the 200-pin DDR2 SODIMM fit the second slot in my Toughbook 74 Mk3 alongside the original module?

Yes, the module is a 200-pin DDR2 SODIMM rated for 800 MHz and 1.8 V, matching the Toughbook 74 Mk3 specification of two sockets and a 4 GB maximum.

How can I confirm the stick is running at 800 MHz after installation?

Check the memory speed in the BIOS or with a tool such as CPU-Z; it should report DDR2-6400 (800 MHz) with CL6 timings.

Does the package include only the memory stick or are tools and extra parts supplied?

The package contains one 2 GB DDR2 SODIMM stick; no screwdriver, thermal pad or additional hardware is included.
