Is Prime95 a good indicator of system stability?

[ahsia]

My new P4 rig has ran fine for a week now, but at 2320MHz, Prime95 fails everytime after about 10-11 tests. If I can run Prime95 for hours, does that mean I have fairly stable system? How does Prime95 compare to other Distributed Computing such as SETI and UD Cancer?

Prime95 is a cpu killer..............I ran it for a while and it seemed to be toughest on the cpu as far as Distributed clients

Seti is hardest on the entire system, cpu, memory, and such

These are just one mans observations though 🙂

I don't know about overall system stability.
But accourding to the people in Highly technical forum, before you buy a chip, the CPU companies do much stronger tests using specialized machines and built in circuitry on your CPU.

Yeah, but the CPU companies do their tests at non-overclocked levels. Your cpu could have failed their tests at a few mhz above its normal speed, so their tests don't help someone who's pushing their cpu beyond normal speeds.

I think Prime95 does a very good job testing the cpu (and I've seen it catch a few memory errors too). Have you tried a looping 3dmark or sandra test? I'd back down a bit (or up the voltage maybe) if your getting errors in Prime95, those little things can corrupt your operating system over time. But I tend to error on the cautious side when testing an oc.

My system was at 2.22GHz and ran Prime95 for 10 hours last night, no errors. I am inching towards 2.3GHz.

How do you loop Sandra? I have never tried 3DMark, will try that later tonight.

<How do you loop Sandra?>

Just run the burn in test, you get options to adjust it to loop!
