Re: About adding RAM
Depending on the mobo, yes that would be the case. but for duel channel ram it needs to be paired, but you can get away with 3 sticks of the same kind, maybe different makers and run fine. but if you use DDR2 800 with a stick of DDR2 1066, the lower clock speed will prevail and all will run at the lowest speed. but like patonb said, read your mobo manual, and you should be good... but if you just want to try it, then make sure the third stick is next to your FIRST DIMM slot, if it's numbered 1,3,2,4, or A,C,B,D, etc...
