1GB DDR1 SODIMM for Panasonic Toughbook 29

This 1GB DDR1 333MHz SODIMM module is built for upgrading compatible Panasonic Toughbook 29 models including the CF-29HTLCZBM, CF-29HWLGZBM and CF-29HTQCZBM. It uses a 200-pin SO-DIMM form factor and operates at 2.5V with CL2.5 latency. The unbuffered, non-ECC design matches the original memory specification for these legacy systems.

Suits owners of listed Toughbook 29 units

This upgrade fits users who need to add memory to the exact Panasonic models named in the compatibility list. It does not fit systems that require a different pin count, voltage or form factor. Buyers with other laptop models or newer DDR generations should verify their specifications before ordering.

200-pin DDR1 333MHz interface decides fit

The single specification that determines compatibility is the 200-pin DDR1 333MHz (PC2700) SO-DIMM interface at 2.5V. Only laptops designed for this exact memory type and pin layout will accept the module. Check your service manual to confirm the required memory standard matches these parameters.
