Core RAM Clock Vs DDR I/O

    Hi Guys

    With DDR2 memory are the actual FSB speeds double those of DDR? I've only ever worked with DDR so I'm a bit uncertain.


    DDR400 works on an actual FSB of 200 MHz * 2 = 400 MHz
    So would a stick of DDR2 800 work on an actual FSB of 400 MHz * 2?

    The reason I'm getting confused is the book I'm working from (Meyers) gives Core Clock RAM Speed and a DDR I/O Speed for DDR2.

    So for DDR2 800 its says Core Clock RAM speed of 200 MHz and DDR I/O of 400 MHz. Basically do I go by the DDR I/O and not the core clock?

    Cheers guys
