    I wasn't sure which thread to post it in so I decided this one because more people are looking at it. So I upgraded the RAM in my 2009 MBP from 4GB to 8GB. It is DDR3 1066 MHz. My brother has an old MacBook with 2 GB of DDR2 667 MHz. Would I be able to put my old 4GB DDR3 in his computer? Would this cause any problems? Would the computer just underclock my RAM to 667 and keep everything working fine?

    Thanks!

    DDR2 mem isn't interchangable with DDR3 mem.

    So no.
