I'm going to go get some more RAM some time this week. I already have 2x256 set up in the dual channel "mode". Now how does this work? Does it make the two sticks just act like one really fast one? Does the computer treat it as if I had only 256mb or does it actually count it up to 512? So after I get two more sticks, with this dual channel will they be added up to 1024 or does the computer think that there's only 512?
