By default the Samsung N130 netbook comes with 1GB of memory installed. This works well if you are just running the standard Windows XP home installation, but if you want to push the boundaries of your netbook and run Windows 7, you might want to upgrade to 2GB (this is the maximum the N130 will support).
Samsung have made it very easy to upgrade and provided an access panel on the underside of the netbook. To quickly see the process, checkout the video below.
The Samsung N130 uses DDR2 PC2-6400 memory.
