Got some good friends there.
What kind of ram do you have and what kind are you getting? I strongly don't recomend mixing different kinds (EX: having 2 sticks of PC2700 and 1 stick of PC2100). The problem this causes is, the faster sticks will downclock themselves so the slower one can keep up. So you aren't really gaining anything, speedwise. And i've heard some cases where it actually ruined the ram, not sure how acurate that is, but still.
