    Hi

    I have got Apple MacBook Pro "Core i5" 2.5 13" Mid-2012 with

    2 x 2GB 1Rx8 PC3-12800S SODIMM installed, can I replace one of these with

    a 4GB 2RX8 PC3-10600S, so I can run with 6GB in place of the current 4GB.

    any help much appreciated

    regards,

    gtfisher

    It will run, but I suggest getting faster and the same type of RAM.

    RAM works best in matched pairs, so I would personally recommend you swap out both sticks at the same time for best performance.

    I would also use the same RAM speed as what your computer came with as you may cause instabilities.

    As everyone else has already pointed out, using differently sped DIMMs in each socket is highly unstable. If you really need the upgrade, either get 2*4GB 12800 RAM or replace one 2GB DIMM with a similarly specced (12800 speed) DIMM.

    Personally, I would advise the former option as equally filling sockets is the best way to go.

    Thanks

    Hi All,

    Thanks for all the informative replies - I was just trying to get away with what I have on the shelf, but I will go for a matched pair of the correct speed.

    Thanks you
