If you are using a Toshiba laptop model, then you need to know something about its memory specification. This information will prove crucial when either doing an upgrade or buying a new Toshiba laptop entirely. With recent advances in memory capacities and memory speeds, it can be a bit like tumbling down the rabbit hole if you do not have the technical qualifications to help you make the best decision at the cheapest cost. Luckily, we have all the technical know-how you need to help you know what to look for and what to avoid.
Usually, Toshiba laptops have a USB/PCMCIA bus architecture. Their memory runs with the help of Intel chipsets, the common one being the 852GM chipset available on modern motherboards. Memory sizes range from single line modules of 128MB DDR2 going up to 512MB DDR3 memory modules. Some other modules that run on different chipsets may require slightly different specifications. However, these specifications are largely determined by the bus architecture as well as the chipsets that mange the memory modules, in this case the 852GM Intel chipset. Pentium III Toshiba notebooks have a standard memory of 256MB of removable RAM. They have a maximum memory capacity of 1GB with 2 memory slots.
When performing an upgrade, any memory slots that are purchased need to be of the same speed and specifications, otherwise the slower memory modules will not be seem and will be of no use to the system. Memory should either be DDR1, DDR2 or DDR3. Each model has its own specifications. The more recent advanced laptop models run on DDR2 and DDR3 memory modules. Before purchasing memory, look out for the OEM part number. This must match the laptop model; otherwise putting wrong memory modules may damage the modules and the motherboard permanently.
