    Hi all,

    Sorry for bringing up a topic that has already come up but looking through some of the other topics didn't really help me. I am looking to upgrade my memory from 4 to 8 gb. Here's what I need help on... so under the system information under the memory tab it says "Your Mac contains 2 memory slots, each of which accepts a 1067 MHz DDR3 memory module." But then all I see on newegg are 1066 MHz, am I missing something here? or are they pretty much the same? What are your guys recommendation?
    heres the one on newegg that I was thinking of getting.

    Here's the Specs (It was a refurb btw)
    MacbookPro 15 inch, Mid 2009
    processor: 2.66 core 2 duo
    memory: 4 gb 1067 MHz DDR3
    Mac OS X Lion 10.7.4

    any help would be appreciated. Thanks.

    That RAM will work. I have a 2009 MBP with two 4 GB 1333 MHz modules and the Mac recognises it as such.

    Regarding the 1066 and 1067 MHz issue, it is a rounding issue, as the RAM is 1066.666 MHz fast, as far as I can remember.
