It’s not the end all, beat all benchmark for a computer.. (is there one?) but SuperPi mod 1.5 popular little program to gauge changes in the speed of your computer for overclocking changes you make, etc…
It calculates Pi out to however many decimal places you want.. 1 million is the one most of the overclocking community use when referencing SuperPi numbers.. It uses a long established Gauss-Legendre algorithm. Don’t look at me.. there are lots of people that can look at formula like that and “read” it and understand it just by looking.. I ain’t one of them. I haven’t known any of them for almost 25 years now either. There are faster ways of calculating Pi to 1M spots but that’s not the point.
My current 1M Super Pi score.. 21.356 seconds. It used to take 35 minutes to get 1M spots back in the days of 90MHz Pentium PC.
2.8 GHz E4300 Core2Duo (default 1.8 GHz) (the fastest I can get it to run 100% stable..boooo a <b>lot</b> of these CPU’s will clock up to 3.2 and 3.4 with minimal cooling and slightly bumped voltages. I’m gonna need a fan on my motherboard’s northbridge though to get 3.0 GHz or above I’ve deduced.

I only scored 21.556 with my quad core and 4 gigs ram (vista is only recognizing 3.5 though) Wonder if I should bump the settings a little just to see where I could go.

My Athlon XP +3700 (2.2GHz default speed), 1 gig of PC3200 Corsair value select ram, plain jane WD 160 gig HD got just over 41 seconds…
Super Pi 1.5 isn’t written to take advantage of multi-threaded CPUs.. it’s just that they are that much faster, Grant. I don’t know if something is set up wrong with your computer… Building a computer that really screams.. or at least goes as fast as it can depends a bit on parts matching.. Falcon NW and Alienware (as examples) have done great job putting together perfectly matched systems that are faster than others with similar parts. I’m not saying yours is screwy, it just seems like it should be faster than 43 seconds though on this test, Grant. *shrug*

I came in at just under 29 seconds. Athlon XP2 5000+ BE o/c to 3.2 w/ 2 gigs of memory and a 250 BG HD.
