I have a blog based upon on the same subjects you discuss and would love to have you share some stories/information. I know my viewers would value your work.

In the event the machine is definitely running Windows XP, for instance, the memory ceiling is 3.25GB. Installing more than this would basically constitute some sort of waste. Make sure that one’s motherboard can handle your upgrade quantity, as well. Good blog post.
