    It will *work* but it's best to stick with two matching sticks of memory.

    Depends on the model of mbp

    Which one you have?

    Concerning matching sticks, it will enable dual channel which gives you an additional ~10% boost in memory performance

    I think you can but as far as I can tell dual-channel mode for RAM will be disabled.

    Go ahead and do it. Dual channel really makes no difference in real world performance. You wont notice a difference at all, except for the fact that performance will increase due to the additional 2gb of ram.

    2gb + 4gb = will it work??

    i basically have the same question as karkid.

    i have a macbookpro 15 8,2 2GHz i7 and have just purchased another 4gb of ram for it as i need it to stop freezing/crashing everytime i use adobe after effects.
    i intend to buy another 4gb ram to accompany the first one (once i find more $$$$ to do so) but would like to know until then will the 2gb + 4gb play together nicely? :confused:

    Yes it will work.
    Half true, it will work perfectly fine however there is a very minor performance decrease. Matched RAM sticks are ideal but not necessary.
