My System Specs

Default Prime95 and other stress tests

So, what do you do when you are running stress tests while checking your latest OC? I am curious because I usually set it and watch for a while or walk away for a bit. Lately I have started just doing some light browsing in a small window with Prime95 up beside it and Realtemp running to monitor temps.

Just sitting around is boring! Anyone else multi-task while stressing the machine?

BTW, I am running a modest 345 FSB for a 3.11GHz OC mem set 2:3 and my temps look to be settling no higher than my stock temps. Vid is 1.225 v and no real other tweaks yet. I plan to keep upping the FSB and keeping my ram close to 1066 until it fails, then up the voltage a little and see what happens.

This is fun!

Use OCCT: 30 minutes for a quick test, a full 2 hours for complete stability.

Let Prime95/OCCT run and play Crysis!

If you have an Intel CPU, there's also this: IntelBurnTest - The new stress-testing program - XtremeSystems Forums

Claims it gets the highest temperatures as it's much harder on the system.

Though honestly, you have such a minimal OC that it's pointless to bother with stress testing yet IMO. You can probably do 400FSB right away. No sense in wasting time with 10MHz or so.

I was going to stick with the proven programs... and I saw something in another thread about that program. FSB at 350 now, temps stable under 50C still, no need to bump the voltage yet so I don't expect the temps to change until then.

I am pretty new at the OC part. After reading up on it I am not to afraid of blowing up my machine and losing it all, I have an Asus and it seems to be one of the better MB companies for recovery from a bad OC.

I'm curious as to why you feel this way about this software...

I have used Prime95, OCCT, Orthos, and Intel TAT. I actually like the interface on Orthos so I tend to use that one but they all work. TAT is an older Intel developed one that I don't believe is supported anymore.

I also will do other things like browsing while it is running. It's not like I can end up stressing it more than it should Although response is obviously impacted by the stress test.

When OC the CPU or testing a new heatsink I tend to use the small FFT's to get the CPU as hot as possible. If I am playing with memory timings I use the mixed test. If I get an hour or so pass from Orthos I treat it as stable.

Now testing the video card is another matter. I can get my GPU overclocked to what ATI Artifact tester says is fine... loop a bunch of times through 3DMark06 and think everything is dandy. Then I start folding and the true stability comes out. The folding is intolerant of any miscalculation at all. Something that is an invisible blip in 3DMark is a bad folding calculation. So now I actually use a 24 hour folding run as my test of GPU stability. Off topic... sort of...

Hiya DDO. Thanks for the input. I don't have Orthos but I will get it to see. I downloaded OCCT and will run that in between as I ramp up. I am shooting for a modest 400 FSB and stable. I am now at 380 without bumping the Vid yet. Running at 1.225v on Realtemp and 1.208v in CPU-Z. My RAM is now at a 3:4 running at 506.6 MHz according to CPU-Z.

I am running the Prime95 blends for 30 min and then SuperPI 1M and 2M to see how it goes before I bump the speed each time. I figure once I get to 400 FSB I will run the small FFTs for 30 min and then OCCT for an hour. I am pretty confident that it will be very stable at 400, and I am still feeling a little gun shy, but more confident as I go up!

As I said, this is kinda fun

Orthos and Prime95 are the exact same thing. Orthos just has nicer interface.

Myself if I can end up P95 stable for 3 hours I consider it good.

If you want to test real stability try folding.

There is no single system test out there. You MUST use them all, and pass, or consider your overclock not 100%!!! Failure in any one test is a sign of instability, and should not be considered a fault of the program...each one provides a differing workload that can cause errors to show when others do not. There is no "quick test".
