I read the RAM guide and am getting a little closer to understanding what it is all about... I wanna upgrade my MBP C2 2,33 from 2gb -> 4 Gb. I realize that I only get 3 GB worth RAM, but understand that the dual-thing makes it worth it. Question: I found a pretty good deal at Newegg. 2x2gb Kingston "Apple RAM" at only 89$. The thing is, it only says "apple RAM". So I am a bit unsure if it is compatible with my model... this is what it says: Kingston 4GB (2 x 2GB) DDR2 667 (PC2 5300) Dual Channel Kit Memory for Apple Notebook Model KTA-MB667K2/4GR - Retail read more at: http://www.newegg.com/Product/Product.aspx?Item=N82E16820134560 Would this work in my MBP? any hlp appreciated... zballz BONUS QUESTION: Would any 2 RAM of the same size have the dual-channel-thing?
