ok so ive upgraded from 2 2 gig sticks of ram to, 2 4 gig sticks of G.SKILL Ripjaws Series 240-Pin DDR3 SDRAM DDR3 1600, the 2 2 gig sticks are the exact same model, just in a smaller size, so my buddy told me that just using the 2 4 gig sticks in dual channel will be faster then using the additional 2 gig sticks i had before (putting me to a total of 12 gigs instead of 8), and to just leave those out. Just wanted to confirm, as I personally have no damn idea. thanks for any help you can provide!
