    Yes it will. At full speed 5400 is 20% faster, but only if it's
    synchronous with the processor's main buss. Also memory is only a
    portion of the overall process, so the actual perceived speed is less.

  2. My motherboard is supporting DDR2 533 ram.
    Will it run DDR2-675 ram but bump down to 533 speed?

    ECS PT890T-A (V1.0) (motherboard)
    Corsair XMS2 2GB 2x1 gb DDR2-675 pc2 5400 4-4-4-12 (ram)

    Will it be prone to crashing or just run slower ram speeds?

    Or should I just get 533 ram?

    Does PC2 4200 run much slower then PC2 5400?

    Thanks!

  3. Its corsair Twin XMS
    The CPU is E6600
    The board is cheap ESC running at 533 speed,
    Operating Frequency 2.40GHz
    FSB 1066MHz

    DDR2-675 pc2 5400 4-4-4-12 (ram) is what I want to run in the dual mode.
    Cheers and thanks for the help!

    You can buy the PC2-5400 RAM, but the motherboard will run it at DDR2-533.

    The "PC" number is the bandwidth, and yes, it is effectively
    bumped down. DDR2-533 means 533 million transfers per second.
    The DIMM is 8 bytes wide, so 8*533 = 4200MB/sec or so. They round
    the numbers a bit, to make the marketing easier.

  6. Last thing I'm wondering.

    The PC "5400" will also bump down to "PC4200" ?

    Thanks, not even corsair tech support knew.
