Chances are you can add two Crucial sticks, and suffer no ill effects. You'd probably want to run Memtest86 http://www.memtest86.com/ to check for errors (I do this on every new machine anyway). As long as the sticks have the same basic specs you'll be fine.

But yeah, dropping one, and adding three identical would be ideal. But ideal isn't always needed.
