Compatible Panasonic Toughbook 30 memory upgrade

This 2GB DDR2 SODIMM module is built specifically for Panasonic Toughbook 30 models including the Cf-30Ctqazbm, Cf-30C3Tabbm and Cf-30C4Pgzbm. It installs directly into the 200-pin memory slot and operates at 1.8V without requiring configuration changes. The single stick delivers an immediate capacity boost for supported legacy systems.

Suits owners of listed Toughbook 30 units.

Buyers with a compatible Panasonic Toughbook 30 can use this module to reach the system maximum of 4GB across two sockets. The memory is unbuffered and non-ECC, matching the original specification. Anyone whose laptop uses a different pin count, voltage, DDR generation or form factor cannot use this part. Systems requiring registered or error-correcting modules should look elsewhere.

200-pin DDR2 SO-DIMM interface determines fit

The module uses a 200-pin DDR2 SO-DIMM connector running at 533MHz (PC2-4200) with CL4 4-4-4 timing. This exact interface and voltage are mandatory for the target Toughbook 30 models; a different pin layout, speed grade or voltage will not seat or function. Verify the 200-pin DDR2 requirement before ordering.

Questions about this item

Will the 533 MHz DDR2 rating still run at full speed once installed in my Toughbook 30?

The module is rated at DDR2 533 (PC2 4200). The Toughbook 30 memory controller supports that speed, so the stick will operate at its rated 533 MHz.

What does the PC2 4200 designation tell me about bandwidth limits?

PC2 4200 means a theoretical peak transfer rate of 4 200 MB/s on the DDR2 bus. Real-world throughput will be lower due to latency and controller overhead.

What physical slot does this 200-pin SO-DIMM need in the Toughbook 30?

It fits a standard DDR2 200-pin SO-DIMM socket. The Toughbook 30 has two such sockets and this module occupies one of them.
