Pifast Benchmark

[cpulloverclock]

Nice work, if you ran 2001 you'd do really well at 3dmark, c'mon give it a go !

Regards

Andy
yes and me = 1000% optimizations for many many crazy scores

[YoupY]

at 3137.5MHz I'll get 37.7s

at 3.7GHz it's easily possible to break 33s with some optimizations with a FX, I dont know what time makes a FX at the same frequency (3075MHz-3087MHz than my 3000+)

That's the difference between a winnie and a newcastle. Winnies tend to be a little bit faster at the same speeds. I have a winnie here too, but it doesn't like the cold :(

I made the deal of a lifetime last weekend and got myself a nice little sweet cascade that does -106 idle for a very good price.

So I'm hoping on producing a 3300 Mhz pifast and reaching somewhere in the 36s.

edit:
Had a little play but no great results. Probally bad contact or condensation problems :(

Mate, your screen say "error in computation" , so it's not stable enough to calculate correctly. Either your RAM or Cpu could be failing here (I guess it's ram).

are you cidding me ofcourse i use the bat file , and i dont entered any mumbers at all why you say that, i'll get this results and thats it, why would i cheat on this im just glad it goes that fast, well you sure can ruin a fine score i post. stupid to think that. why type my own numbers? i dont wanna be a cheater i'll get around this score every time i run THE BAT FILE :rolleyes:
and i can use a DVcam and film before and during the test uncut, my son will come in next week and he can film the test an then i'll post it so you can see it, is that good enough for you :p:

It is suspicous (not saying u cheated) but I think the WR is something like 32 or 31. I know for a fact it isnt in the 20's though.

True it is but the guys on top are still faster than you are, that's why it still applies.

I'm using the latest pifast, running the bat.file... Then how come 33.96 from september 2004 is faster than 28.73? By the way did you check my timings, tight enough for you? or do i detect a spot of jealousy in all of this , it's in black and white 28.73 :fact:

[nutcase]

first, All the records were set using Hexus Pifast..

The two runs (ignore scores, were done on my everyday machine) were done like this:

Top one is using Hexus Pifast which uses pifast41.exe

Bottom one is TheLab Pifast which uses Pifast43.exe

Notice over 15 seconds difference between them and they were ran on the same Machine..

so you mean that i have to use an older version to get an acceptable score on pifast? thats look insane to me!!! then all must run with the newer version to get correct scores, since it seems a little bit pointless releasing a new version that shows inreliable results... But still, your post's the one making most sense here, "all other posts seems to be just doubt about me faking the results :slapass: "

EDIT: here it's run in same speed with pifast41

It's simply another version. Hexus <> Pcenter

It uses another algorithm IIRC, wich is little slower.

Hi, i'm new, but i'm doing a research project about cpu temps when calculating pi. If anybody could post some times temps n cooling methods they used to achieve them, i'd appreciate it. Any information helps.

thx

[flclisgreat]

i feel dumb for asking this but how many number's are we supposed to calculate?
how many is normal?

hexus.pifast.net download the package, run the bat, not the exe

Also.... (air)

[sparkY1000]

Sorry to sound like a complete newb but how do you run this benchmark? It gaves me so many options and im just not sure which ones I want? sysfailur says something about running a bat file but there wasnt one in the download just an exe and a txt

I Stopped maintaining Pifast because of all the cheating as it is cheatable, I did have a word with the program maker but he was un-interested in sorting a fix.

However its as simple as... downloading .... http://pifast.hexus.net/hexus_pifast.zip

and then run the file hexus_pifast.bat

[spaglia]

I don't think QuickPi is cheatable. How are the cheats done?

[PMM]

A person would have to go to extra lengths to effect QuickPi but I have just confirmed it can be messed with... see pic below

A liitle time and effort and easily made less noticable.

I see, of course -- changing the system clock skews the times. I was thinking more along the lines of tampering with the output. Ah well, where there is a will, there usually is a way...

I think I can fix this, anyone interested?

After running this again on my home machine a few times I like it :) esp as its multicore friendly it kind of brings in a new type of tinkering to get max speed the run above I did at work.

I think if you can certainly put into place....
1) An anti cheat
2) A Validation at the end to confirm the calculation is all is OK
3) Suggest an autorun batch file to say kick off a 10M run as a fixed benchmark standard.

I think you have a winner :nod:

Version 4.5 is is available here:

Let me know if you can easily cheat it. The app can compute a checksum over all the digits and you can verify the correctness that way (by comparing it to a known good checksum). Use the -check option. Other options are the -bin and -stats options. By submitting the resulting binary file, it can then be independently varified.

Passed my test but I admit I'm not clued up in the ways of tripping progs up.

I have PM'd Kunnak here in the view if he is willing to put his superior know how to give it a thumbs up.

Excellent work by the way http://www.brittech.co.uk/thumbsup.gif
