Old MacBook RAM compatible with New MacBook?

[Hankster]

I installed 2 extra GIG of RAM into my plastic MacBook last year. I'm assuming that same RAM is compatible with the new Alum MacBooks. Or, do I need to purchase new RAM?

Thanks for the assistance.

Won't work....DDR2 vs DDR3

no, because there are 4 more pins on the new DIMM
