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

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.

from his replies to me I dont believe he knows what a core even is
 
I Have a Early 2011 Mac book pro 17
and have 1600 mhz ram in 8 gigs of them 2x4
intel core I7 2,2Ghz
8 GB 1600 MHz DDR 3
 
My 13" early 2011 running 1600mhz kingston RAM

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.
