Kingston 512MB DDR333 SO-DIMM

This 512MB DDR333 module uses the 200-pin SO-DIMM form factor and runs at 2.50V. It is built specifically for compatible Toshiba notebook computers that accept PC2700 memory. The unbuffered design matches the original system requirements.

DDR333 (PC2700) speed rating

The module operates at DDR333, delivering up to 2.7GB/s memory bandwidth for the supported platform. This single speed specification determines whether the part matches the notebook's memory controller. Verify the system requires PC2700 before purchase.

Fits Toshiba models PA3312U-1M51.

Installation requires an available 200-pin SO-DIMM slot in a listed Toshiba notebook. The upgrade frees the system from the original capacity limit by adding 512MB of compatible memory. No heat spreader or ECC circuitry is present.

Questions about this item

What real-world bandwidth does the 2.7 GB/s figure deliver in a notebook?

The DDR333 module provides up to 2.7 GB/s memory bandwidth, which is the peak throughput the memory controller can use for typical computing tasks.

How does the DDR333 PC2700 interface limit performance in practice?

The DDR333 PC2700 interface caps the data rate at 333 MT/s, so the memory cannot run faster than that speed even if the chipset supports higher rates.

Will this 184-pin DDR SDRAM fit the SO-DIMM slot in my Toshiba notebook?

No, this module uses a 184-pin DDR SDRAM form factor, while the compatible Toshiba systems require a 200-pin DDR SO-DIMM.
