    Hey everyone, I have a mid 2009 MBP and according to Apple the specs of the RAM are:

    FRYS has an awesome deal for 8GB of RAM for $21 after rebate. The thing is that the RAM is 1333MHz and not 1066 MHz. I was wondering if it would work? I believe that the computer would max at 1066 MHz, I'm not sure if thats 100% true. Thank you for the help!

    As long as the Pin count and type (DDR2, DDR3, etc) matches, faster RAM is supposed to be backward compatible to work with older standards and should give you no issues. Fry's has a pretty good return policy as long as you make it within the time period, so you could try it out and see (it won't hurt your system if it doesn't down clock correctly).

    As stated you can't go wrong.
    You'll be able to use the kit with newer hardware for when you upgrade, if necessary.
