FSB won't run at 133 mhz

[perseus]

I was referring to their website FICA AD11 There it says the FSB for my mobo is 266 (I have the 1500+ - 1800+)

I replaced the motherboard with an Epox 8K5A2. Problem fixed! :thumb:

I'm not understanding the 133/266 thing. Can someone explain to me how FSB 266=133 and 200=100?

Now this is fairly easy, the FSB is running at a true 133MHz but because it is double pumped each cycle is delivering 2 pieces of data per cycle(each 1MHz) this effectively doubles the rate to 266MHz.
With a P4 and their quad pumped FSB (4 pieces of data per cycle) this effectively turns a 100MHz FSB into 400Mhz and 133MHz into 533MHz. ;)
