as for the second part it depends on your mobo , you'll have to look it up in your instruction book , most new boards are colour coded but generally if for example in order from left to right you had.........
A1 A2 B1 B2 for dual channel with 2 sticks you would go A1 B1 , you can also fill all four and still be dual channel
