    It's DDR - so, 2 x 266 = 533MHz. ;)

    no dude, DDR = Double Data Rate. This means each stick is 533mhz (~266mhz x 2)
    Don't worry, your memory sticks are fine!

    DDR2 technically runs at 133MHz internally, but because it transfers four bits of data at one time, you multiply the memory clock by four - so 4 x 133 = 533. ;)

    DDR only transfers 2 bits of data at the same time, so it would actually run at 266.

    That's also one of the reasons why DDR2 uses less power.

    ChazMan is correct, I was going to say that Intel's bus infrastructure has 4 channels, so it's 133mhz x 4.

    ChazMcgraz you beat me to it :D

    Cheers,
