I've got a 15" early 2008 model MBP with 2gb of RAM. I just got snow leopard and am looking to max out the ram at 4gb. i know what type of RAM i need, and i came across these two on crucial's website. is there any difference in these? they have different model numbers, i know one says it is for a mbp and the other doesn't, but they look the same? i ask because i found the second one elsewhere online for under $50. i really appreciate the help, this is my first time purchasing ram for a mac!
