What's so new about PiFast?

 

[GenTarkin]

Well its not really NEW...but lots of peeps havent heard it, therefore to this forum for the most part its news.

anyways I just got a new all time best score for me =)

Program : PiFast version 4.1, by Xavier Gourdon
Computation of 10000000 digits of Pi
Method used : Chudnovsky
Size of FFT : 1024 K
Physical memory used : ~ 61163 K
Disk memory used : ~ 0.00 Meg

This was done at 3.371ghz memory 468.5mhz

 

[THUGSROOK]

it seems to be pretty accurate too.

i OCed 2fsb past stable and it caught me with an error

 

[Elcs]

I might up my fsb to 145 :brokenheart:

My PCI cards dont like being run out of spec too much and on my EPoX 8KHA+, I dont have a 1/5th divider

_____________ NOTICE THE DIFFERENCE ? __________

(from the post above)

I downloaded the new version ... then modified the batch file to use the 4.2 version

- I made no system change either .... still my normal 441 DDR Dual

Intel Mobile P4 @ default (1200mhz, 400fsb), will be right back with results at 2005mhz, 668fsb (thats as far as i can go with the damn p4b266)


edit: , not great, but its a step in the right direction

my second time around, using pifast 4.2, on an AXP @ 2170 MHz

a 14 second improvement over version 4.1, not too bad...
