    You can, but why bother? Just use 1066 MHz, as it is what Apple ships it with and supports.

    Ah! You're welcome. :)

    1333 MHz will work, although there have been sporadic reports of problems with it in your machine. In some places, there is enough of a price difference to make trying it worthwhile; but for the tiny price spread these days I'd just suggest going with 1066.

    I would go with the 1333, if you have problems with the ram more than likely it was a bad stick to begin with. I run 1866 in my laptop and I had so many negative responses saying it's not going to work blah blah blah. Well it does and I don't have any problems.

    If anything, the memory will downclock to 1066. Buying 1333 will allow you to use it in a newer machine as well.
