Super Pi is a program that calculates pi to a specified number of digits after the decimal point up to a maximum of 32 million. The Gauss-Legendre algorithm which is a windows version of a program used by Yasumasa Kanada in 1995 to compute Pi to 232 digits.
Super Pi is used by many overclockers to test performance and stability of their systems. In this community, Super Pi has become the standard for providing benchmarks to compare pi calculation times and demonstrate their overclocking skills. The program can be used to also test the stability of a particular overclocking speed. If a computer can calculate PI to the 32 millionth place after the decimal without a mistake, it is considered moderately stable in terms of RAM and CPU performance. More intensive CPU and RAM tests include calculations that run for hours instead of minutes and better test system stress levels.
XtremeSystems branded Pi released! No physical code changes other than heading at top of dialog box.

I had to go back to the previous timing, 15 msec jumps are back :( Problem was the high precision timers were giving completely wrong results on systems clocked over ~4 GHz.

Restarted from scratch. New features are an even more precise timer, no more 15 msec jumps. A checksum has been added which you can validate using the form above. Also results are now saved in an encrypted format for the jokers that like to edit the save file :) Your old results will no longer be loaded, a new file (pi_rec.dat2) is used. Sorry about that but it was the easiest way.

Moved the code around a bit and changed back the section permissions.

Added more cheat protection. Try to cheat and it'll crash :)

Added cheat protection. I changed the text in the title bar so people can see that you haven't cheated when you post a screenshot with your results.

Super pi mod now loads/saves the result times in msecs in pi_rec.dat. The original pi_rec.txt is no longer used in this version because it just wasn't worth the trouble. Super pi originally stores the results in seconds internally so I had to do quite a bit of editing to get this to work at all :)
