Compatible DDR2 upgrade

This 2 GB DDR2 SO-DIMM is built for the Toshiba Mini Nb305-N310, Nb305-N310G and Nb305-N410Bl notebooks. It installs in a 200-pin slot and runs at 800 MHz with CL6 timing. The module is unbuffered, non-ECC and operates at 1.8 V. Buyers needing more than 2 GB total memory or a different form factor cannot use this part.

Low-voltage operation

The stick draws 1.8 V and has no heat spreader, so it runs cool inside the compact Mini chassis. With only a single rank of 2Rx8 chips, power draw stays modest during typical workloads. No active cooling is required and the module adds no audible noise to the system.

Direct slot installation

One module fits into either of the two SO-DIMM sockets, leaving the second socket free for another identical stick if desired. The 200-pin DDR2 interface matches the notebook’s memory controller without adapters. Systems limited to a 2 GB maximum will not accept larger capacities.

Questions about this item

How do I install the 200-pin DDR2 SO-DIMM in my Toshiba Nb305, and which step is often missed?

Power off the notebook, remove the battery, open the memory cover, insert the module at an angle until the gold contacts are hidden, then press down until both side clips click; the step often missed is reinserting the battery before the first boot.

What maintenance or replacement will this 2GB DDR2 800 module need over time?

No scheduled maintenance is required; replacement is only needed if a memory error appears or if you upgrade the system to a newer platform that uses a different memory generation.

What limit appears first when this CL6 1.8V module runs under sustained load?

The thermal limit of the unbuffered chips without a heat spreader is reached before any electrical throttling, so sustained write-heavy workloads may warm the module to its safe operating ceiling.
