How long do you stress test before you consider it stable?

[kiicki]

I have been overclocking my Ryzen 1600 to 3.8GHz at auto CPU voltage which is 1.2375v with the stock cooler. Realbench ran for 8 hours without any issues, where I can't remember the max temperature atm, but it was a few degree higher than with Aida64. I ran Aida64 for 14 hours without any issues, and the max temperature was 66C.

 

I'm now running Aida64 where I change to 3.9GHz with 1.3v. Ran for an hour without any issues. Currently it's at max 80C.

 

I have heard people only run a stress test for 30 min to an hour. I find that to be a bit too low, but I'm new to this. I have had stress tests that had issues after 2-3 hours. People don't seem to want to stress test their CPU for hours because it's bad for the CPU? Putting so much stress on it, for a long period of time.

What's your give on it? What softwares do you use to stress test your CPU, and for how long? I personally skip the Cinebench stresstest/benchmark. I go straight for Aida64 or realbench for 15 min to an hour, and for the final stress test I run RealBench for 8 hours, and Aida64 for 12-24 hours.

I usually do a test on Adia 64 for 12 hours and game or render a model for a few hours to see if it's stable in real work applications. Testing is always a continuous approach which needs to be monitored over time, I've had situations where it's passed all artificial stress tests but failed in renders or other applications.

yeah, I have had Aida64 running for hours, where Realbench would freeze my computer in a few minutes, and vise versa. I'm surprised that I hear people only stress test for max an hour because they don't want to put too much heat on their CPU for a long period of time. I don't know if you can know if it's stable then. I have also heard from other sources that 6+ hours of stress tests are long gone with newer CPU's? They say running IntelBurnTest for 20 min should do it. Is this true?

8 hours Realbench, 8 hours OCCT  (x2 testing modes). If it survives that it's good enough to ship and see if it crashes during regular usage.  (Because let's be realistic, no one is maxing a CPU out for that long in normal usage anyways).

 

I've had OC's crash at a 4 hour mark so 1 hour isn't really good except as a gross check.

Call me an idiot but I just test for an hour lol

I should check out OCCT. Never used it. What's your give on IntelBurnTest? Some sources say that the OC should be stable if you run this for only 20 min

[AnonymousGuy]

IBT is running linpack I believe which is apart of OCCT anyways.

If it works then I guess it's alright. I'm just new to OC, but I have had stress tests fail a few hours in, which IMO means it's not stable. I have had many tests pass after 1 hour in Aida64, and with Realbench, but later failed.

Intel burn test puts it under the worst case scenario where it suddenly load and unloads the CPU which usually is where you will see an overclock fail. I personally stick with Adia64 and realbench for the most rudimentary stress testing (long term testing around 12 hours) but for me it's more about putting the system under a real work load to determine if it's stable. The only way to find out is if it fails just one time no matter how much stress testing and loading it's been done since then, when it fails just once your overclock was not stable enough.

1h then use PC as usual. If it crashes, increase voltage by a very small amount until it's stable.

[QuestionxThree]

I do like 30 min and never had issues 

 

30 min stress test and my pc has not been off in a month lol and it’s fine

My experience showed me that no one single stress test will fully exercise everything in the CPU for an overclock.

So rather than run any one test for long, I try to run as many different tests as I can find.

If you've got any games or other programs that put a heavy multi-threaded load on the CPU, then add those in too.

 

I came to this mindset when I found that the overclocks that I thought were stable cause my system to "reliably crash" every time I loaded a particular game that thrashed my CPU, all cores maxed, in ways that clearly none of the stress tests were doing.

at least 5 years, you need to know the pc will last the full length of time you are going to use it for.

Aida64 is potato test IMO

 

I like OCCT. It stops as soon as an error is detected, so it can detect unstability without even the computer crashing or BSOD etc. so very sensitive and stressful.

 

The best is to use many, with 8 to 24 hours test each.

 

OCCT, Realbench, Aida64 are a good trio IMO

 

Even if aida64 seems like a potato test to me it might stress it in other way than another app.

 

 

Also having long session of battlefield 1  very cpu intensive, I had situation where my build pass a aida64 12 hours test but BSOD after 1 hour in BF1. I solved the problem with bit more voltage so it was indeed related to unstability.

I usually go for 8 hours as I am not that intense in stress testing anyway I only game and chill on the computer so not many chances I hit that high cpu usage in every day usage
