Now back when i overclocked my system (in sig) about 2 years ago, the Intel Burn Test prog wasnt even on the radar, everyone suggested using Prime. After some recent problems with my mobo i have gotten my OC back, and decided to try out IBT, now all my settings are just as they were back 2 years ago when i first past an 8 hour Prime test, but now IBT fails on the 4th run through on Normal stress levels!

My system has always been stable, never got a blue screen in the whole 2 years etc, but according to IBT my system isnt stable. Seeings in the next few weeks i shall probably getting an I5 setup, and aiming for a 4.0Ghz should i just ditch Prime when stressing my OC and just go straight for IBT, as that can tell me in 5 minutes what Prime couldnt tell me in 8 hours!! Just seems a hell of a lot quicker way to find out if your system is stable

Hehe that's quite along time between system checks!

Two years is enough time for a PSU to weaken, Memory develop errors etc, have you tried running the same test on a stock system?

IBT (like Prime) is one of half a dozen system diagnostics used to stress test hardware, its not the be all and end all but if it fails then there is an underlying problem.

The thing with IBT is it loads the processor more than anything else and causes the CPU to run extremely hot, it also requires the CPU to drink a tad extra vCore than anything else so while a CPu may be getting enough voltage during Prime (and your day to day stuff) IBT will leave it wanting more.

How are your temps under IBT full load?
 
Those temps are fine under IBT and wouldn't cause the processor to error.

If this is a case of the CPU not getting enough voltage then you can bump the vCore up a little then IBT may pass, if not try upping the vCore a little bit more still . . . . try and keep full load temps below 80°C

The errors may well not be CPU_Undervolting related but boosting the processor voltage and testing again is a good trouble-shooting step! :cool:

What were the recent problems?
 
Basically, my BIOS wouldnt remember any clock settings, in the end it was the new corsair hx 750 psu. So i just hooked my old psu up, changed the settings in the bios, and they were then saved, then i replaced the psu back
 
When I use IBT the CPU rev counter gadget only goes to 50%. Prime sends it to 100%. Am I using IBT incorrectly? Both run without problem.

You trying to use it with a Hyperthreading enabled CPU? IBT does not load a HT CPU 100% due the HT obviously spreading the load over the cores. Try LinX, very similiar to IBT but it is coded for HT I beleive
 
I personally use LinX, IBT and Prime to ensure my system is stable ... I've had times when IBT said it's no good but the system would be fine for months.

Are you using an i7?

If so you need to use 16 threads in IBT for the CPU to get fully loaded..

TBH you should just use LinX instead, it uses Linpack just like IBT but fully loads the processor without having to run 16 threads..

As Wayne said, it has something to do with Hyperthreading..

I understand now, I'm using an i7.
