Developed by some folks from the University of Tokyo (yes, Japan), Super PI is a small utility that does just as the name implies. It figures PI to a set number of decimal places. Since PI is an infinite number to the right of the decimal point, the utility measures the time it takes to figure a set number of places. It runs the calculations a set number of times and gives a time for the completion of the task. This is a simple and effective way to measure the raw number crunching power of the processor being used to compile the results.

With only .15 of a second separating the numerous setups we can see that at the same FSB the increased memory speed is not giving us a huge effect. It is not until you start increasing the FSB and let the memory go with it that we see big gains in Super PI.
