    Hi! I've updated my 2011 mac mini server with 8gb of ram, and now I have two original ram sticks of 2 gb. My sister has got a 2010 Macbook, can I put my ram in it (even if the ram in the macbook runs at 1066 and my ram runs at 1033 )?

    The Mac Mini Server 2011 model takes PC3 10600 or 1333Mhz RAM which will not work in a MacBook 2010 model system due to it taking 1066MHz. You can not mix the memory speed in these systems. If it takes 1066MHz from factory than you want to put 1066Mhz in it for the upgrade otherwise it will not work.

    That's not true. I have 1333MHz RAM in a 2008 MacBook that had 1066MHz RAM from the factory, it works fine.

    Agreed. I upgraded my 2008 to 8gb 1333MHz and it works great! I did find out the hard way that 1333MHz was as high as it will allow.... I have some 1600's laying around now :(

    For the newer i3,i5, and i7 series processors that is correct but for the older Intel Core 2 Duo's, and Intel Core Duo the processor FSB is the depending factor as to what speed of RAM the system can take. With the new i3,i5,i7 series the memory controller was moved to the CPU so it is the deciding factor.

    I'm running 2x4gb 1333mhz ram modules in my Asus w/ i5-520m, which is rated for 800/1066mhz modules. Its been working fine for close to a year now.
