AthlonXP & Soyo Dragon

O.K., so I bought a Soyo Dragon Lite motherboard and an Athlon XP 2100+ CPU and, since the add said the mobo needs PC2700 memory, I bought a 512 MB stick as well.
Could someone please explain to me why I needed this high-end stuff if the FSB and CPU run at only 133 MHz ? It seems like the Dragon board can run at up to 333 MHz and the memory at probably 266 MHz.
What is the advantage of having PC2700 memory over PC133 if FSB speed is only 133 MHz.

Any info is appreciated.

  1. I think that is because the board uses DDR (double data rate) memory which equates to 133MHz*2=266MHz. This means calculations are on both the tick and tock side of the clock.

    Just a basic explanation. At least you got some fast memory for later upgrades.
