moved to hardware section.

2 additional GB should usually suffice. However it is only reasonable to get RAM with the same specs as the other 2GB so if you should get details on that (something in the format like this 7-7-7-28, maybe get that info from bios).
Which version is your Vista? with 32bit you can only utilize up to 3.25GB
