Super PI

[Crixx_Creww]

Well i cah find trini last thread so i makin this one as a lil note


Ive been trying to beat his 40 something second timin on his silly little amd but so far i cant.

So i tried the 1 million calculations with hyperthreading off to see what would happen and low and behold.... the calculations were a wopping 2 to 3 seconds slower with out hyper threading.

         I did at least 11 tests to confirm this, and to my amazement its true, hyperthreading really does make a difference!
*gasp* to all the besmirchers of hyper threading

forgive me eh hoss.

But i ah bit lost on d *hyper threading/pi*

of course it actually works. its more or less a (as i like to put it) virtual second cpu on the same die. i personally don't like intel. im a amd man myself.                    

[Bourbon_Ghost]

ohhhh..... is processors your'll talking about?
WTA i could have sworn is something else.......hmn

Yes : trini and his little AMD puts intel to shame

 OF course HT makes a diff, but 2-3 seconds is the same diff made by closing  your anti virus software before you  benchmark, or restarting . It doesn't truly enable the processor to do 'multiple calculations at once' as advertised,  but it DOES speed it up a bit .
   Let me give you some tips : restart, then close all non essential software , i'd imagine going into Safe Mode will provide a few seconds boost , but haven't tried it yet .  
 
 PS: Athlon XP @2.4GHZ = 3.2/3.4GHZ P4 , upgrading my  crappy aluminium sink to a giant solid copper one , we will see some even higher overclocks soon
my score was 43 secs to 1 mill pi @ 2.4ghz, 425 FSB .

Yuh know I am sure, let me say that again ABSOLUTELY POSITIVE I posted my time on this topic... seems someone's been doing some editing.... mods... admin... hmm whaev  anys, here it is again:
1M: 47s

rig:
2600+ Barton oced @ 2.31GHz
1GB Kingston Hyper X PC2700
A7N8X-X mobo
thats all the important stuff

VIVA AMD!


  got my new totally silent copper HSF.... not all that big after all . I can POST through 2.6GHZ [ wouldn't do that with aluminium] but windows keeps locking up .  
   the new LGA 775 prescotts are alot better [ as i predicted] they don't go above 45 C with stock aluminium HSF . And overclock 400-500mhz . Considering that i pulled off a 700mhz with my Athlon mobile i'd still say AMD  is betta .
    I want someone to play around with the A64 mobiles.... they probably can clock like mad too .  
   my record remains 43 secs to 1 mill pi , i'll try to beat it when if i ever get a faster fan, and have the machine in a VERY cold AC room .  

 good job with the barton W1nTry , what kinda cooling u got?
