Prime95 - New Releases

Nelly · 25 Apr 2012 at 23:21

New version of Prime95 specifically for Haswell CPU's.

From developer: 30th August 2013
For any Haswell owners that are interested, an evaluation version 28.1 is available. I have some ideas to improve it further, but they will take some time to implement.

I sure hope it works correctly because I've started using it on my Haswell box

Fixed the bad self-test data.

This seems to stress my memory a lot more than the previous version on 3930K.

A couple of updates since I posted this.

Mprime -v does not print out the build number. Fixed in version 27.6 build 4.

Torture test on small FFTs gets round off errors or crashes after a while. Fixed in version 27.6 build 4

Is there something wrong with the site as I cannot download, or get to the site?

Jokester · 3 May 2012 at 21:08

Working fine here.

SirCanealot · 3 May 2012 at 21:23

Had a few problems with it here. You might need to try and few times till it works...

Prime95v.27.7 Build 1 - 4th May 2012

ftp://mersenne.org/gimps/p64v277.zip

Torture test on small FFTs gets round off errors or crashes after a while. In very rare cases, regular tests could crash or raise a round off error. Fixed in version 27.7.

Multithreaded FFTs could deadlock. Fixed in version 27.7.

Seems the bottom link is not working, I also notice quite a few different release's due to issue's, are these version's good to test for stability while over clocking?

Edit, seems there is a even newer release.

Prime95 v27.7 Build 2

Thread revival, new build released this month i.e. December 2012.

Minor bug fixes.

Cool, thanks

zepzeppelin · 25 Dec 2012 at 07:36

It's getting more and more difficult to get stable on these new versions, my 3570k would pass 4.5GHz @1.256v now it needs 1.320v or more on this new version, why is that? because it's rocketing the temps into the high 80's and even low 90's

Another way to degrade your CPU's and only prove your system can run Prime 95!!! Nice

swiftmetal · 17 Sep 2013 at 10:39

Unless you are developing prime (why it is needed I do not know) there is no need for it.

Look at it another way if you wanted to to be able to run for 1 mile a day for health reasons would you really start running a marathon a day risking injury or worse just so you then could get to your goal of 1 mile a day? NO

As 8pack always suggest the best way to test that your computer is stable in "normal" use it to is to use it normally.

why no prime update for fx chips

Another Yorkshire guy with the right approach!!! Un-surprising

!!

To the AMD guy prime is not needed so don't worry!!!

swiftmetal · 17 Sep 2013 at 13:37

Us Yorkshire lads know where it is at and it is really not torturing the very expensive nice shiney things that we buy and stressing them to the point where it may cause serious damage for no point.

So how does OcUK test stability on CPU's guaranteed to run at 4.6GHz, as an example?

Tbh, ive given up on programs such as p95/ibt. This chip of mine under a decent air cooler runs way too hot with such programs. 81-93c across the cores. Just use my normal tasks such as games, rarely see temps over mid 60's. With my previous 3770k, i could pass hours of p95 or multiple runs of ibt, fire up bf3 and it crashed seconds into a round.
