Pentium 4 chips work on a "quad pumped" bus, meaning that for every clock cycle on the bus, the processor and chipset send and receive data four times. Thus, the effective transmission speed of data is actually four times higher than the actual speed.

Think of it the same way DDR works... Running a DDR memory stick at 200mhz means that the effective speed is 400mhz because it is transmitting and receiving data two times per clock cycle.

Why did I just mumble all of that?

133mhz actual FSB is 533mhz effective (4 x 133 = 533). You're already at the appropriate speed.
