help regarding ram

hi, my motherboard is asus m4a78td

and basically i have 2 lots of 2gb 1333mhz ram

and 2 lots of 4bg 1333ghz ram,

just wondering would i be better off just using the 2 lots of 4 gb, or would it be better to put all of them in and have a total of 12, ie 2 lots of 4gb and 2 lots of 2gb??

I'm wondering the same thing, because I just bought 2x4gb sticks of ram, but I also have 2x2gb sticks.

Put them all in if you use 12GB, otherwise just put in 8GB.
