1GB DDR 333 SO-DIMM for Panasonic systems

This 1GB 200-pin DDR SO-DIMM runs at DDR 333 (PC 2700) with CL2.5 latency at 2.50V. It is an unbuffered, non-ECC module without a heat spreader, built to match the original Panasonic part numbers CF-BA511024 and CF-WMBA401024B as well as Gateway 5000735.

Who this suits and who should look elsewhere

It fits owners of compatible Panasonic notebooks that require a single 1GB DDR 333 SO-DIMM. It is not for systems that need ECC error correction, registered buffering, a different pin count, or a higher module capacity than 1GB.

Deciding specification: 200-pin DDR SO-DIMM at DDR

The 200-pin DDR SO-DIMM form factor combined with the DDR 333 (PC 2700) speed rating is the single specification that determines compatibility. Only notebooks designed for this exact pin layout and signalling rate will accept the module.

Questions about this item

Will the 200-pin DDR SO-DIMM slot wear out from repeated upgrades?

The 200-pin SO-DIMM socket is rated for many insertion cycles; under normal use the module itself needs no maintenance and will not require scheduled replacement.

What limits sustained throughput on this DDR 333 PC 2700 module?

The CL2.5 latency and 333 MT/s bus speed set the bandwidth ceiling; the memory controller cannot push data faster than the rated PC 2700 specification allows.

How much heat and power does the 2.50 V unbuffered stick produce running all day?

Operating at 2.50 V without a heat spreader, the 1 GB module draws modest power and runs cool enough for passive airflow in a Panasonic notebook chassis.
