Ok I have a question , I am looking at ram on new egg and I know to dual channel you have to buy in pairs, and to quad channel you have to the 4 sticks In the same kit , so how does dual channel work do I simply put the two sticks in the mb that supports dual channel and it automatically does it or do I have to configure it , and also can I dual channel and put another stick in will that still be dual channel with a separate stick. Or I am limited to 2 sticks if I choose dual channel.
