Dude, Where's My 4 Gigabytes of RAM?

So if I really want everything I get out of my memory, don’t I want 3x 1GB sticks, AND 1x 512MB stick?

then you loose the dual channel benefit.

18,446,744,073,709,551K of RAM ought to be enough for anybody.

anyway since windows has a limited life…(vista is like 5 year support)
