From what I can tell my mac was built the first week of October in 2007, it has 1gb of RAM with the 2.0 processor and running Snow. I want to upgrade the RAM but I find different answers to what it can take. OWC says it can take up to 6gb, cruical says it can only take 3gb and apple says 4gb. Which one is it? I plan on buying from newegg. And another question is on newegg they have a mac memory section but you can by the memory in the pc section for 10 dollars cheaper, there isnt a difference correct? Still debating on what memory to use, Kingston, Cruical or OWC. Thanks for help in advance.
