Help with testing stability

post #1 of 10
Thread Starter 
I have my Phenom 955 at 4.2ghz stable. (using S&M cpu)
I was able to validate it at 4.4Ghz but it crashed during S&M.
http://valid.canardpc.com/show_oc.php?id=1650067

I was wondering what other programs I should use to stress test? I don't know that much about it and I hear people using P95, Orthos, Intel Burn, and I was just wondering which one is the best? Or which one is the most commonly used?

Also, I'm using a Coolermaster Hyper 212+ and all my voltages are set to auto. Would manually setting my voltage to 1.475v-1.5v help increase stability? And should I use the ref. clock and multi. for OCing? Or is just using the multi. fine?

Thanks for any help.

Prime95 is the most commonly used test.

BTW Why is youy voltage on auto ... set it manually. And yes increasing it will help in stability but don't go over 1.55 and max temp is 62c !
Also what is S&M ?

Well out of the few tests that I have tried, S&M seems to cook the CPU a little more.

(Scroll down the the "S")
And I'm using 4+1 phase so didn't want to raise my voltage to high so I left it on auto.

The max temp I've seen while trying to get it 4.4Ghz stable was 55c.
At 4.2Ghz its 52c.

Prime95 is great for stability testing. Intel Burn Test will test for stability and will max out your CPU temp.

LinX or IBT 20-50 passes for temps, they are both Linpack frontends.

Prime95 blend 24hour for long term stability test.

I think you're only need to be stable in your day-to-day applications.
For example, my 1075T are fully stable for hours under stress tests like Prime95 @ 1,45v\\4ghz, but it'll fail at some point when @1,425v. Still i have it @1,425v because it's enough to be fully stable in games and my day-to-day tasks. I don't use Prime95 everyday, so i don't need that kind of stability.
Same for gpu's and Furmark, it's better to have MINIMUM stable voltage in day-to-day tasks than trying to achieve useless 24\\7 stability under stress tests...

S&M??

I'm a big fan of simply running OCCT for an hour. It generates more heat than P95, and generally will fail within 10-30 mins if your OC is no good. If you plan on doing anything with sensitive data, or folding at home, then maybe 24 hours of P95 is what you need.

Doesn't OCCT use Linpack ? You could get the same with Orthos/LinX.

I thought Orthos was more like Prime.
And OCCT has both Linpack and the OCCT test.

If you keep your RAM at stable settings you can just use Prime95 small FFTs and lower the time to run each fft from 15 to 6-8. If you're not stable it'll throw an error within the first 10 minutes about 80% of the time.
