Prime 95 .

[_ASSASSIN_]

if you get new components and are planning to watercool them immediately, I would definitely  stress test it for 24 hours, really

for overclocks, like everyone else, 10-12 hours should be enough

[Volbet]

I always stress tested for 48 hours. Nothing is stabil if it doesn't pass a 48 hour stress test (atleast in my opinion)

Jesus that is insane lol

 Agreed unless you plan on having your PC maxed 100% for that long theres really no need.

We only ever did a stability test for like 8 hours and we've never had a computer back

Are you saying youve only tested 1 PC for 8hrs ever? If thats the case are these being OCd? Are then under a good amount of constant stress or being max completely for extended periods?

No, numerous, I'm being a retard and forgot the 's' at the end of 'test'

 

And they were overclocked, not massively, the last time was with a Core i5-2500K about a year ago which was taken to 4.2GHz, I can't remember the voltage.

[L.E.D]

I have never overclocked....

8 hrs should be plenty if its just a light OC and it wont be sunder a sustained load or full load for and extended period 

 

That OC almost seems like one you might be able to hit wihout changing the voltage which is kinda a nice way to oc using the turbo multiplier so you not eating up power but you still have a bump in speed.

I read all these responses and it seems like a lot of people don't understand stability. 

I always run at least 24 hours. I have had overclocks fail 17 hours into Prime 95.

You can't just say that - "I think if it passes 2 hours it's stable enough"

A computer is either stable or it's not. If it fails at some specific calculation because of your overclock, you never know when that calculation will actually affect your experience, it might be in the middle of a game, it might be a browser tab crashing a month after your overclock or it might be a game giving you some error on start that you're trying to solve. My point is, an unstable overclock could do as little as prevent one program from starting up or functioning correctly half a year after you overclock, the problem with that is that you'll get an error, and you'll try to solve it, and you might spend hours trying to figure out why this one thing doesn't work or why this one thing crashes only to figure out that it is that unstable overclock you did months ago. 

 

Yes leaving your computer on for 24 hours might seem like a waste of time, but it might just save you 24 hours of troubleshooting.

If you have a custom build you should still stress it for some amount of time to makesure you dont have faulty components or when you do use your system to the max somethings not going to fail, overheat, or what ever.

i'd say running it for 7 hours in my case, then using it for 4 months without a single crash....is enough proof its stable for me.

 

Even if you pass a 24 hour it doesn't mean its stable at all, as programs and games may still crash, (happened to me)  the only way to do a true stability test for me is to use the damn thing as you normally would would  saving regularly if you are doing work, and you will find out a hell of a lot quicker if it is stable or not that way,

CPU / Hardware Stability and Software stability are 2 different things.

Programs can crash even if the hardware is stable just because software isn't perfect and has bugs and mistakes. I mean it's thousands and often millions of lines of code there is bound to be some mistakes in that. 

 

That doesn't change the fact that everyone should make sure that the hardware is 100% stable, you want it to make calculations with any mistakes and carry out instructions accurately, even if those instructions have bugs in them. 

[grayperview]

Running a stress test for a long period is no guarantee that the OC is 100% stable  I have seen chips go through long stress tests pass them, and then have Apps and games crash all over the place on them, because the voltage is too low.

 

I have even had it on my current CPU.

[Beskamir]

I use prime95 for a few minutes checking to see what my max temps are and if something isn't stable I'll find out if I get a BSOD...

[qwertywarrior]

i keep prime95 on for an hour

i find it pointless to keep it longer

[fracking4oil]

Does folding qualify? I haven't run Prime anymore than about 2 hours and 20 minutes at my current overclock, but I did fold for about two weeks straight.
