This is a pretty cool site that allows you to have them check your system for memory. Interesting. I suppose this would be a pretty useful thing to do, rather than the alternative of lugging your entire tower up to the store and having them check. Which we all know, you’ll wind up buying much more than memory. lol So, if you want to test your systems computer memory, you should click that link.
