    Why does HP only offer DDR memory at 333 MHz with the AMD processors on their website?

    I'll take a stab at this -

    I know the desktop AMD XP's run at 166 FSB, so DDR is 333. Betting the Turion is the same.

    Intel probably runs at 100 - quad pumped is 400, 133 - quad pumped is 333, or 166 - quad pumped is 667.

    Okay, my first assumption was disproved, and 133 quad pumped is 533, not 333 - typo.

    Does this mean that since the Intel Core Duo's are offered with 533 MHz memory that would be faster?

    Well, No(atleast the first part of your explanation). The Turion, Athlon64, Sempron do not have an FSB. The integrated memory controller runs at the same speed as the cpu. So, if you have a 2.0GHz cpu, then theoretically the cpu is capable of using memory upto that speed. But given reality, it is limited by the BIOS and the current availability of the memory modules. The Turion64 supports memory upto DDR400, whereas the Turion64 X2 supports memory upto DDR2 667.

    It is HP's bright idea to use DDR333 instead of the maximum supported DDR400for the Turion64. They use DDR2 533 for the X2's which are comparable to the Core Duo's. So considering the whole system the Core Duo will be faster than the single core Turion.
