im having mobo p55m-p33 msi. its had dual chanel rams. 4 slot (blue black blue balck)


currently I have two wonava 2gb ddr3 with 1333mhz x2.

I planing to add kingston hyper x 2gb ddr3 1600mhx x2

how can I get the max speed? and how it works in dual chanel. I dun really get it.

can I configure like this
blue (1333) balck (1300) blue (1600) black (1600.)

or I cant mix it. so I must do it normal way.
blue (1333) black(1600) blue (1333) black (1600)

what max speed I will get from both configuration
