    hi all,

    looking for advice on adding more ram to my late 2011 mbp, running 10.8.5 (might upgrade OS though when i change the hard drive soon)

    At the moment i have 2 x 2mb ram in it.

    Anything i should be aware of? someone mentioned 'is my machine a 64 bit machine' ? as that makes a difference with the ram apparently?

    Obviously i don't want to put more in if i can't make use of it.

    I'd like to get it to 16, if possible, but at least 8.

    many thanks

    Your machine will accept up to 16GB of RAM.

    All macs made after 2009 boot with a 64-bit kernel.

    Thanks guys. I think I'll go with crucial. They seem to be the leaders in ram

    If you go to crucial there is a form where you fill the details of your machine and it tells you the correct RAM.

    You don't need to use the scanner, just enter the correct details.
    I'm running 16GB of Crucial 1333MHz DDR3 RAM in a 13 inch late 2011 MBP.

    There is some sources that say you can use 1600MHz DDR3 RAM in the late 2011 MPB 15 inch with i7 cpu (not the 13 inch - different CPU).

    I just replaced my flakey Patriot RAM with Corsair last weekend. Computer is back to running normal.

    I have a late 2011 mbp 13". It has 4gb ram installed at the moment, I'd like to take it to 16. Can I simply buy 12gb ram and install that or do I need to start a fresh and buy 16?

    You'll need to remove your standard RAM and install 2x8GB modules.

    The machine has 2 slots, and for best performance you want to populate both slots with the same size sticks so that the machine can read and write to both sticks at the same time for better speed.
