noob fsb question

[scoobyx13x]

I bought an AMD Barton 2500XP (retail box) that is supposed to have a 333mhz fsb.

But when I look at the fsb frequency setting in the award bios it says the frequency is 166mhz. I seem to be able to adjust the frequency to 100, 133, 166, and 200 mhz but 333 is not an option.

I have a Biostar M7NCD motherboard, which is supposed to support a 333mhz fsb.

Can someone please explain this to me?

166x2=333DDR

Thanks

I didnt say anywhere that it was multiplied by 2

fsb = 166
system(memory) bus = 333
