I am going to create a new computer for my brother. I have bought a good motherboard from our neighborhood store. The name of the motherboard is xfx 790i. As you know it has a dual channel ddr3 memory. Now my thinking is adding a ddr3 triple channel. What will happen if I do so? Will it going to operate proficiently inside the motherboard? If yes, how can I make it work? If No, What would be reason for this difficulty? Any information would be much appreciated.
