IntelBurn vs. Prime95

post #1 of 21
Thread Starter 
Ive been told that Intelburn stresses the CPU harder and so Ive been using it for the past few months and I must say that its very inaccurate in determining whether my CPU is stable or not!

A year ago I used to use Prime95 and after passing 10 hours of Prime, my system would be stable for months. Whereas now after doing 20 passes of Intelburn high, the stability of my system is still a mystery and I get the occasional BSOD

So may I ask, what the eff? Why do people claim Inteburn is awesome?

I like to use a combination of both. First 50 runs in IBT maximum memory, after that passes 8-24 hours of Prime95 on blend.

Run IBT for 10 hours, that'd do the trick.

I find IBT is a "Yeah, it's kinda stable, can withstand some pushing."
Then I prime is to really work out the kinks.

IBT = Quick, cheap, nasty but it gets the job done mostley.
Prime = Long Haul, Refined, Good and finding small things.

I'm sure if you ran IBT through 150 passes and it were stable, then you'd be golden.

If it passes that then nobody can argue that your overclock isn't stable.

IBT is a linpack test, which is more demanding than a prime test (or it used to be). Now a lot of SB overclockers are running Prime 95 on blend aswell.

use both
prime blend found instabilities in my ram after 3-4hrs that ibt wouldn't pick up

I run 3 IBT passes on Max and then move on to Prime95. I find that IBT finds instabilities fast in both Core and Memory(to some point). However Prime95 for 24-36 hours will stress your PC closer to what real loads put on your PC.

IBT just feels so much more synthetic to me that it often misses stability errors that mprime finds.

IBT is just for CPU stability. Prime95 small FFTs is for CPU stability, Large FFTs for Chipset/FSB stability and Blend for mem.

IBT stresses the CPU more than Prime95 small FFTs, however, you will never use any programs, games or nothing that pushes your CPU close to Prime95 small FFT's. Therefore one can say that if your Prime95 stable, you are indeed 100% stable for everything you will use your computer for.

I use IBT myself, and have been for a good while. However, I have now begun to think it is total overkill, almost ridiculous. The thing is that you can be stable in Prime95 Small FFTs on a certain CPU Voltage, but when you fire up IBT the load CPU Volts will drop further than Prime95 small FFTs. And this can make the CPU unstable in IBT, whereas it was stable in Prime95 small FFTs. However, as I've stated earlier, Nothing, neither programs or games will even come close to Prime95 small FFTs load on the CPU. And therefore Load Volts will not drop as much as Prime95 small FFTs.

So I'm beginning to think if I should skip IBT All together. It is ridiculous and overkill.

And by the way, IBT can not be used as indication of chipset/FSB or Mem stability. Just for CPU.

its not. p95 is better. p95 makes it easier to diagnose instability. it gives you more symptoms to look at. different errors. bsods. ive always used p95 and nothing else.

All you need is Prime95. Run small FFT for an hour. If it passes then run Blend for 24 hours. This test has never failed for me. If you can do this your system is good to go.

I used Prime95 for years... Long before the Linpack script came out, and if it was stable in Prime95 I had no problems whatsoever when it came to stability
