Help with overclocking intel p4 cpu!

Actually the FSB is the bus speed. It's 133MHz. Intel calls it 533MHz. That's why you see two numbers. Intel and AMD advertise their bus speed in data rate, not clock speed. Intel uses Quad Data Rate technology for 4 transfers per cycle. Hence the 133MHz clock rate provides 533 mega transfers per second.

Overclocking might be a bit hard. I'd expect around 2700MHz from that CPU. But your motherboard doesn't support changing the bus speed manually.
