System-specific DDR2 upgrade

This 2GB DDR2 SO-DIMM module is built for Toshiba Mini NB300 and NB305 notebooks that use 200-pin memory. It targets owners of those netbooks who need a direct replacement or a single-stick upgrade without guessing compatibility.

Standard 200-pin SO-DIMM build

The stick uses unbuffered, non-ECC chips at 1.8V with no heat spreader, matching the original factory form factor. Its 200-pin edge connector drops straight into the two SODIMM sockets found in the listed Toshiba models, requiring no adapters or bracket changes.

800 MHz CL6 speed rating

Rated at DDR2 800 (PC2 6400) with 6-6-6 timings, this module runs at the higher speed the platform accepts. Buyers whose system only supports 667 MHz (PC2 5300) modules should verify the motherboard specification before ordering.

Questions about this item

What does the DDR2 800 PC2-6400 rating limit in real use?

The module runs at 800 MHz with CL6 timing and 1.8 V; the system bus caps throughput at the PC2-6400 bandwidth ceiling.

Will the 200-pin SO-DIMM fit the Toshiba NB305-N410BN-G slot?

Yes — it is a 200-pin DDR2 SO-DIMM matching the notebook's SODIMM socket and the listed 2 GB maximum per slot.

How is the stick installed and what step do people miss?

Power off, remove battery, open the memory door, align the notch, press firmly until both clips click, then reassemble — skipping the battery removal often leaves the slot live.
