RAM/Memory

Hello everyone!!!!!

I was curious if the Macbook models have 4 slots for memory/RAM or only two slots? (For the 2nd White Model, for $1,299). Also, if I were to buy more RAM/Memory the only requirements is that it is DDR2 Memory, Correct?

Thank you!

There are only 2 slots for memory.

sanity is absolutely correct; most laptops, including all apple laptops going back to at least the PBG3, have no more than two slots. There are (or were) some that have 4, but I'm not aware of any that are currently in production that do.

As far as what kind of RAM you need, I suggest reading this:

In short, yes, it needs 667MHz DDR2; PC5300 or PC5400.
