Ok, so this question has been asked before but it wasn't really answered in a way that I wanted. I need to know if the first gen Macbook can be upgraded to (2) 2gig ram cards. I currently have 2 gigs in my machine. So I wanted to buy 4 gigs knowing that I would probably only get 3.3 gigs out of it, it is still worth it to me (until I can afford to upgrade my whole machine...). That was a simple question but then everyone started saying that the Santa Rosa chip was the only one that could take all four and that the C2D was the only one that could take all four but only use 3, and it really just became a tug of war of he say she say. I know that it can physically take the 4 gigs of ram, but will it be able to use 3.3 gigs of it? Or will I still be stuck in 2 gig land?
