FSB Speeds

Hi i have a question on the FSB, please help me i am a newbie.
Ok
On the amd barton cpu it says 333mhz fsb, but does this mean the cpu multiplier uses this speed to calcuate the speed of the processor?
like 333mhz times 6?

I dont understand this and all the FSB speeds on motherboards and such.

please direct me to some guides or explain this to me please.
cuz sometimes on processor it says like 333mhz and some motherboards only support like a 166mhz times 12.5... why would i buy a 333mhz fsb processor if you only use 166mhz?

im sorry if im too newbie
thanks

    166MHz is 333MHz.

    166MHz x 2 for the way DDR handles calculations = 333.

    Which is why a 200MHz FSB Athlon uses DDR400, and why 133MHz FSB Athlons use DDR266, etcetera.

    It's FSB (Real MHz (133, 166, or 200 for example)) * Multi.

    So 166 x 10 = 1.66GHz, 200 x 10 = 2GHz, etc.

    So with my 333mhz barton i would need at least DDR333?

    Generally speaking, yes. On an nForce2 board, you could get away with using PC2100 (assuming you have 2 identical sticks)
    , but there isn't any reason to, realistically speaking, unless you already have PC2100 sitting around.
