Hi all, I've seen a few videos on replacing Macbook Pro memory, but I'm not 100% sure what type of non-Apple RAM is worth investing in. I also have zero experience purchasing or researching what type of ram will actually work with my computer, so I appreciate any help you all can give. As of right now I have two slots filled, each with 1gig each of DDR2 SDRAM @ 667MHz. I'm not sure what the max size is per each slot, my guess is 2 or 4 gigs. Does anyone know? Secondly, I need a recommendation as to what brand is worth investing in. I noticed this listing on New Egg for a single slot 4gig for $120, seems like a good deal but I might be off: http://www.newegg.com/Product/Product.aspx?Item=N82E16820220495 Thanks for the help. Looking to jump into Starcraft II shortly.
