In search of RAM

I spent most of the day trying to figure out what kind of ram my desktop needed. I always had someone else do the upgrades for my computer. Taking my brother's advice about how easy it is to install more memory. I deecided to give it a try. I managed to figure out what memory i needed and took off to the local CompUSA store. I got to the store and found the memory (with some help). It was kinda expensive so i decide not to buy and see if i can find something less expensive online. I notice that is so many types of memory. Yesh, I spent most of my time just figuring out all the acconyms mean. Who am i kidding it was fun.
