I don't think anyone has shown running P95 or other stress testing apps used to validate system stability, lowers the life of a CPU. In fact I rarely here of a CPU ever failing unless it's had extreme over-volting or over-temps for extended periods.

How long people run P95 or other apps is up to them. If you can't run P95 for 24 hours without errors then the system really isn't 100% stable. I fully understand that many people don't really care if their PC will run 24 hours error free, but that is the gold standard for good reason.

Yeah I understand that but really I dont usually ever leave my system running for a full day. I use it for several hours a day usually then I shut it down or put it to sleep and thats it. Also, I am changing the clock speeds all the time as well depending on what I am using it for too so everytime I do that the system has to restart anyway.

Personally running p95 for an hour is more than stable enough for me. Im not saying that it is going to be 100% stable but stable enough for me. Usually when I overclock high anyway, its only to play games or benchmarks or video editing sometimes. I really dont run my system all the time at super high clocks. I am running at 4.2Ghz now doing video editing. Personally, I really dont see that much of a difference when running at 4.4Ghz or 4.Ghz or 5Ghz so I only really clock that high to share my performance results with the OCN community.

When testing stability I run prime for an hour at the most. Usually if you can make it through the first 10 min of prime without stopping or errror then systen is pretty stable. I have ran the settings above on prime for at least 45 min to confirm stability for me. I see no reason in putting that kind of stress on the chip for no reason. Thirty minutes of prime is stable enough for me.
Ill do this for you only if its a good reason. Otherwise, if its just cause you dont believe me then you'll just have to take my word for it. I'll only run prime when I have to. Like I said, there is nothing I use my system for that will cause that much stress on the cpu. 30 min on prime is stable for me. I see no point in running prime for 3 or 6 or 12 or 24 hours. I think that its just a waste of time and all it does is lower the life of your chip.
If you really need to see a screen shot then I'll run it for an hour at the most. I dont like putting that kind of stress on my chip for no reason.

Heavy cinebench, video convertion, bf3, lots of applucation put a lot a load (+80%) in all the cores available. Transistores are made to be used... Anyway, I had several times passed prime for more than 3 hours and failed when I was playing a game like bc2 and bf3...10min it's a joke it doesn't garantee any stability cause it hasn't explored all the possible combination of loads and possible calculations.

I can say to you that a "stable" computer should run unless 12hrs of prime and 2hr of linx cause linx can get CPU erros pretty quick, while prime blend is good for IMC and memory while still stressing some cpu..

3hrs of prime is the minimum recommended run to check for a reasonable stability in cpu and a good stability fot imc/ram cause it runs most of the most stress patterns for imc and ram.

3 hr of prime blend + 2hrs of linx is recommended for a sormal user,gamer that want a stable computer for average daily loads. I do prefer a really reliable PC so I run it for 12hrs and 2x of linx.

Ram and NB can be very tricky, believe me.

I'm with you. I never did see the point in running prime for hours at a time. Heck, I consider mine stable if I pass cinebench and sandra. I have my pc on for practically the entire day. I never run anything for daily tasks that stresses all of the cpu cores 100% so it's pointless for me. As long as I can get through my daily tasks and gaming for a couple hours without a bsod, then it's stable enough for me. I really think some people go too far with the prime stability thing. If your setup is stable enough for what you do, then that's all that should matter IMO.

i find intel burn test to be better than prime 95.

I've had system be prime 95 stable, and not intel burn test. I would never run prime 95 now for 24 hours. We talking about wasting tons of electric, and making my computer room uncomfortable (temp wise)

I do run tasks which will stress the cpu 100%, many video stuff, but my system needs to be rock stable. When overclocking i will find its peak, then back it off some to ensure stability.


if it passes intel burn test, great, if not, i will use prime 95 for an hour, if that passes then my system is stable enough for daily use.

Thats the oppsite to me,
Can pass hours of IBT/Linpack to have it fail with in 1min of prime.

Linpack/IBT arnt very good on FX chips since those programes stress the FPU which the Bulldozer has shared between 2 cores so your only putting half the load on it compared to prime.

Have to agree. IBT does not fully stress these cpu's. I get about 10° hotter running prime95 than ibt

Folding is my stress testing. I`ve had my CPU pass P95, IBT, 3DM11, CB11.5, but fall flat its face and crash 30 minutes into folding.
