    Quick question..

    What is the difference between ddr3 1066 mhz and ddr3 1333 mhz ram?? I can't seem to find anything on this.. And when I check prices the 1333 is alot pricier.. I guess the 1333mhz one is better but what exactly will it do better in a laptop in general?

    The difference is just clock speed.
    DDR3 PC3 8500 is 355Mhz memory (1066MHz effective), and
    DDR3 PC3 10666 is 444Mhz memory (1333MHz effective).

    No current laptop cpu has a FSB over 1066Mhz, so their is no point in buying the DDR3 1333Mhz memory. The 1333Mhz bus of the memory will automatically clock down to PC3 8500 (1066Mhz) speed.

    Save your money and get 2-4Gb of PC3 8500 memory

    OCZ - then nevermind? :)

    What supported 1333Mhz ?


    There is no point in getting more than 1066Mhz anyways, only core i7 (which is only desktop) can fully use the ram specifications and raise performance. On a core2-system it won't matter no matter what clock speeds you got on the RAM as the memory-bus is in the northbridge and not in the CPU :)
