Hi Everyone! In my search for memory, I found this site, which claims that the white MacBook, the 2.13 Ghz model supports up to 6 GB's of memory. Here's the link :6 GB So my questions are... 1)Is it actually compatible? I mean the memory that they are offering is PC6400 and its a kit of 2GB + 4GB... 2)What memory comes in a standard config from Apple with the 2.13 Ghz MacBook? 3) What kinds of memory are compatile with the White Macbook - 2.13 Ghz? Thanks in Advance!
