The speed of the CPU and RAM depend on the speed of the motherboard's Front Side Bus (FSB). If the FSB speed is 100MHz, because of the Double Data Rate technology (DDR) the RAM speed would be doubled internally to 200MHz and the CPU internal bus speed would be quadrupled to 400MHz because of the Quad Pumped technology.

If the FSB speed is 133MHz, the RAM speed would be 266MHz and the CPU internal bus speed would be 533MHz.

If the FSB is 166MHz, the RAM speed would be 333MHz and the CPU internal bus speed would be 666MHz.

Yeah, it's confusing, but go over this a few times and it'll start to make sense.

Oh, the internal bus speed of the CPU isn't the CPU's processing speed, it's the speed that data moves inside the CPU itself. The CPU's processing speed would be determined by taking the motherboard FSB speed and multiplying it by the CPU's multiplier ratio. Take a 2.4GHz P4 that runs on the 200MHz FSB for example...you would take that 200MHz and multiply it by a ratio of 12 to get 2400MHz or 2.4GHz.
