    Hi all,

    I would like to update my MacBook Pro 5,1 with two 2GB modules to 4GB. The current RAM is running on 1066MHZ but the new modules at my computer place are only available with SO-DIMM 2GB DDR3 1333MHz.

    Would the MacBook Pro 5,1 work with two SO-DIMM 2GB DDR3 1333MHz RAM modules too?

    Thanks for all the redirects and relies!

    Wait, where am I again?
    It should be able to support 1333MHz RAM, though it will be downclocked to 1066MHz.
    I have heard reports of stability issues (largely due to the chipset not supporting it all too well, as well as the increased CAS latency) with such RAM on MBPs and iMacs, though, so I'd be a bit careful.

    Thanks for the reply!!

    It seems I have to bite the bullet and go to an Apple store and get it from there :(

    check NCIX, Newegg and other sites...they sell ones clocked @ 1066 mhz.
