Hey guys this may seem a stupid question, but I cant remember how much RAM can I put on my Macbook Pro .... this is the one before that it just came out .... right now I have 2 GB I would like to upgrade to 4 GB but I remember that I read somewhere that some macbook pro just can upgrade until 3GB ... s Im wondering which one I have ? what other info do you guys need ? some of my specs are ..... I bought it on October 2006 so Im pretty sure this one is the one before. 15"" Macbook Pro 7200 2.33 MHz Inter Core 2 Duo.... 2GB Ram X1600 ATI Radeon Thanks.
