Panasonic Toughbook 30 Memory Upgrade

This 2GB DDR2 SO-DIMM is built specifically for the Panasonic Toughbook 30 models CF-30FCS72AM, CF-30FCS73AM and CF-30FCS75AM. It targets owners of these rugged laptops who need to restore or increase system memory to the supported 4GB maximum. Buyers with other laptop platforms or newer DDR generations cannot use this module.

Single Module Simplifies Installation

The package contains one 2GB stick, allowing users to populate a single empty socket or replace an existing module without buying a matched pair. This keeps cost low for systems that only require one slot filled. Systems already at the 4GB limit across both sockets will not benefit from adding this unit.

Standard 200-Pin DDR2 Form Factor

The module uses the 200-pin SO-DIMM interface keyed for DDR2 at 1.8V, ensuring physical and electrical compatibility with the Toughbook 30 memory slots. No heat spreader is fitted, so clearance inside the rugged chassis remains unchanged. The unbuffered, non-ECC design matches the original system architecture for direct installation.

Questions about this item

Will I need to add a heat spreader or active cooling to the CM256645300SO module later?

The module ships without a heat spreader and runs at the standard 1.8 V for DDR2 667; no extra cooling is required for normal operation.

What limit will I hit first if I keep the Toughbook 30 under sustained load with this memory installed?

The system maximum is 4 GB across two sockets, so total capacity is the first ceiling you reach before bandwidth or voltage becomes a factor.

How much extra heat and power does the 2 GB DDR2 667 stick add when the laptop runs all day?

At 1.8 V and CL5 timings the module draws only a few watts, adding minimal heat to the existing thermal design.
