Dual channel Ram?

Question

I currently have 2 512mb ram sticks of the same time so its dual channel but i have 2 slots open i was wondering if i added 2 more 1GB sticks of the same type would everything be dual channel

but i was meaning since i have 2 512 CARDS that are the same and i have 4 slots 2 black 2 white

i have the 2 512mb cards in the 2 white and i want to put the 2 1GB cards in the black for 3g.it should still be dual channel right

Answer 1

Yup, as long as you add them in pairs you will retain Dual Channel status, which usually gives you an overall system performance boost of 3-5%.

Answer 2

If you want to maintain the Duel Channel operation all of the memory cards should be the same. So in your situation I would purchase two more 512 memory cards. Or just run the two one gig sticks in the slots that are now occupied by the pair of 512s. 2 gigs should be plenty. That all I run in a Vista environment, and it works just fine.
