One thing I would like to say is that before getting more laptop or computer memory, look at the machine in to which it could be installed. When the machine is definitely running Windows XP, for instance, the actual memory threshold is 3.25GB. Setting up more than this would just constitute just a waste. Make sure one’s motherboard can handle the actual upgrade amount, as well. Good blog post.
