How long should I run stress tests (I use prime 95)

[appplejack]

I heard different ideas about how long a stress should be.
I overclocked Core i7 920 with Noctua NH U12P close to 4.0GHZ and ran Prime 95 for 5 hours without any error. I also ran various games. Race Driver : GRID only made my computer crashed. But I don't bother with it because I also ran games with heavier requirements and forgot to turn on the cooling fan on GPU (EVGA GTX 260 Core 216 SC 65nm). This GPU could get hot easily.

Anyway, I just want to hear what other people think about how long a stress test should be. There are some people who think running Prime 95 for more than 12 hours is impractical because it's too stressful to load CPU 100% for that long.
Thanks

P.S.: Please have a look at my other thread about overclocking results. What do you think of voltages and temperatures?

Overclocking Help Plz

The recent results are at the bottom.

Thanks

i agree. 12 hours is stupid. I do 3 loops of each torture test. Never had a system that was unstable if it passed those. takes less than an hour.

Give it like 3-4 hours on smallFFT

Where do I download smallFFT? I googled it and only found old versions.
And what does it do?

Its in Prime95 .. its one of the tests.

Use IntelBurnTest if you really want to find out if it is stable:

IntelBurnTest - The new stress-testing program - XtremeSystems Forums

prime95 is older than the hills and really should be retired since it is not designed for modern processors.

I fold using BOINC.

HAHA please do not say such false things.

If Prime95 was garbage it wouldn't still be the #1 thing for testing CPUs.

All that Intel does it allow you to see how hot our machine gets and proves nothing.

Machines that failed on Intel pass on P95... and vice versa.

Prime 95 is not old. It has been around but is constantly being updated. The latest version pounds all 4 cores on my q6600. And like I said, If I can pass 3 loops of the torture test my system never fails on any other test or mega hours of gaming.

Vice versa? Not. I have yet to have a machine pass ITB that failed anything else. I do, however, find machines and overclocks that are presumed stable with prime that cannot pass ITB. Prime has not been updated in a very long time. They just updated the core to run 4 instances at once. Prime is a good place to start but ITB is the final verdict. ITB uses a far better process to stress the CPU much further.
