To slightly amend the above^ It may work. Mix and match RAM pairings don't always work. They certainly have the capacity to work, as people have gotten them to work, but there are also people that attempt to mix and match the same exact RAM and don't get the desired results. That's why I've only got 3 sticks of RAM in my machine instead of the four I bought. The fourth stick didn't play nice with the first set I bought when I made the computer.
