How many passes of IBT should you perform to test stability of a new OC?

Also I presume at max settings?

I also have OCCT and Prime - is there a better programme to test stability?

cheers

personally if it passes 20 runs of ibt i am happy,
but other users will recommend 50 runs of intel burn test and a 12hr+ run of prime
 
IBT - 5 or so to confirm general stability
Prime95 - an hour or two to confirm long term heat/voltage stability. The latest version does a better job on Ivybridge than IBT.

Once those pass, just use the PC as normal and if it crashes during general use up the voltage slightly.

Most crashes occur during load changes. Many people report Prime95 crashing after 20hrs+. This is most likely due to a background process kicking in, causing a voltage/load change. Stressing for more than a few hours is pointless imo.
 
Running IBT pass 18 out of 30 so far.

I5 2500k @ 4.7ghz
65deg C
1.328v

Finally looks like I may have a stable oc. I was previously just changing the multiplier and leaving everything else, but it kept crapping out!! Kept BSOD during the night or even after an hour of prime earlier today!!

Followed someone's "guide" on YouTube for a similar (same make) board/CPU and so far so good.

I thought I had a un-overclockable motherboard for a bit there!! Lol

An opinion on my part, yes.. however i've just hit system 300 last week since Jan 2011 when Sandybridge came out.. What has never failed me is a 24-48hr run of prime95 and 100 IBT runs. Now, since Prime started using proper AVX extensions i've even revised previous stability tests when the opportunity came up and a couple have failed, sorted them though.

Funnily enough though those that passed 24hrs prime non-avx and IBT/LINX AVX but failed the new prime were stable in day to day usage with the odd hiccup, seems since being stable in the new prime the odd hiccups stopped (not BSODs, usually just app crashes). Must say that about 95% passed the new version though, so they were likely rock stable to begin with. Just my opinion.

do u work in a shop? as 300 builds is crazy :eek:
i think the difference is, as a home builder i can probably get away with fewer tests, as if something happens, i am there to sort it out,
but to be supplying preoverclocked builds as a service, i would be doing like u, as u dont want any comebacks, and time is money

Part time, little business venture on the side with a friend who owns a PC shop/Business PC supplier, 300 is small peanuts, only about 15 overclocked PCs a month. I've probably built about 700 non overclocked ones in all since 2009 as i managed to consult with a few schools ( i work in the tech side of Education full time) and land a few contracts. Luckily we just supply the PCs and integrate them into the preconfigured network infastructure so don't need to support software (biggest nightmare). We're no where near being 'big', only 5 staff and somehow survived the downturn in economy, not getting bigger or smaller!
