What exactly is Pi?

The Greek letter Pi [ ] is used, in mathematics, to symbolise the ratio of a circle's circumference to its diameter. It is commonly used to calculate the area of circles and the volume of cones and spheres.

The value of Pi is a constant and has been determined to be approximately 3.14159. For more accuracy, you can download a value of Pi calculated to 32 thousand decimal places.

The lower the calculation, the faster your PC.

let me the 1st to support this thread, hoping more result will come after this

CPU : C2D E6300 L624
CPU clockspeed : 2.52Ghz
RAM model : CORSAIR VS DDR2 667
RAM capacity : 1GB x2
RAM speed : 360MHz, 3-6-6-17-1T
RAM mode : Dual channel

CPU : C2D E6300
CPU clockspeed : 3.15GHz
RAM model : Kingston Value RAM DDR2 667
RAM capacity : 1GB x2
RAM speed : 900MHz, 5-6-6-16-1T VDIMM 2.3v
RAM mode : Dual Channel

SuperPi 1MB calculation = 18.827s

Here's mine, guess I mistaken the DDR1 and DDR2.
<18s

eh... i thought Intel runs 2T all the time?

dunno, actually I also copied and paste what was written by gengstapo lol..

Dun think that matters anymore now with C2D. Even memory timings doesn't do much to results.

nope. intel run 1:1 all the time



wahh.. copying w/out permission arr??
lol.. mine running at 1:1, dunno bout urs

soulfly is talking about the command rate. You are talking about FSB:DRAM ratio. That is 2 different thing

hahaa.. ya lorr, my bad

Server got mad and end up with 2 post.

SuperPi 1MB calculation = 32.782s

w00t.... a lot difference in single channel and dual channel for AM2 superpi 1M

nice one Cyclone87

Yea, single channel and Dual make differences. But his results not impressive actually. Even S939 with UCCC can hve that score. Or S754 Sempron with TCCD hitting 2.7ghz

it doesn't matter. everybody knows AM2=S939/S754

updating mine....

32.922s
