    Hey guys I have the late 2011 macbook pro 13 inch 2.8GHZ intel core i7
    with osx lion 10.7.3


    the problem I have is this : i bought this one
    KHX1600C9S3K2

    so as u can see this is a 1600MHZ but after installing i'm still running on 1333mhz!

    Did I bought the wrong one?

    Grtz!

    The 2011 MBP takes 1333MHz DIMMs. Just putting in 1600MHz DIMMs won't make it go any faster - the system slows the RAM down to work at the speed it works at.

    I don't think you'll have any problems, but moving forward you should definitely get RAM and other components similar to what your system has already.

    I have seen many screenshots on t his forum of macbook 2011's that run 1600mhz! with benchtests to prove.

    But they all had a 2.2 or 2.4 no 2.8

    were the screen shots of 15"

    maybe the quad core has something to do with it?

    Apparently it's not working with yours. :) You asked a question, I answered it, so I'm presuming now you're not disagreeing with me. :D Remember, just because something may be working on a different system configuration, doesn't mean it will be working with yours.

    I believe your MBP comes with the i7-860 processor, which supports up to 16GB of 1333MHz memory.

    The screen shots you saw were from the Quad Core. The other poster is correct in all of his/ her assumptions and statements that you were seeing screen shots from a 15/17" QUAD core I7. You even pointed out the clock speeds from the screen shots (2.2 or 2.4) which were not released in the I7 dual core on a 13" MBP, and all of the 15/17" versions have quad cores, so that is the answer. The QUAD cores support it and the dual cores do not.

    Did you receive the correct RAM? Did you check the stickers/packing slip/etc?

    lol, I didn't checked this, but now that I did I saw they delivered me the 8GX and not the 8G, so here's my next question :

    wil my macbook be noticibly faster with 1600 beside 1333mhz?

    because I saw that the ones i received are 7euro more than the one i paid for!

    You won't see a significan difference between the two. There's a difference, but not huge.
