I seriously question the need for all this 24hr testing going on your brand new CPU, I see numerous cases here of guys bragging about their 24hr stress testing, or saying someones overclock is not stable because they haven't benched for 24 hrs.

A stress test is running all of your CPU cores flat out for however long you run the test, unless of course a core drops out because your overclock is unstable, I see the need for short term testing say an hour or maybe 2, because it won't take that long for an unstable overclock to show itself, but 24hrs in my opinion is not necessary.

There is not a thing on this planet designed to last forever, your precious CPU included when companies like Intel and AMD, guarantee their CPUs for 3 yr warranty time period, they're confident their CPUs will actually go past that time period, however that calculation is based on 3 yrs and beyond of normal use.

They know their CPUs are capable of lasting under normal spec'd use longer than the 3 yrs or they would not warranty them that long.

Now the cold hard fact is that overclocking your CPU will shorten its lifespan, but we accept that for the additional speed we gain, most of us will replace that cpu with an upgrade before is life expectancy arrives anyway, so taking it out of specifications is acceptable.

However that's with normal day to day use, surfing the web, audio and video editing and converting, gaming, office documentation Etc, and though serious bench stress testing is necessary to achieve a stable overclock, what damage does stress testing over a 24 hr time period and beyond, actually do to shorten the lifespan of your new CPU.

For example if you stress test your new quad core CPU for 24hrs, and all 4 cores are running at 100% for 24 hrs, how much normal daily processing is lost, because no daily application uses all 4 cores at 100% for 24hrs, so at least think about that when you overclock your CPU, and use at least some kind of wisdom in your stress testing.

Because if you don't think you're adding to shortening the life of your CPU, you're wrong!

well different strokes for different folks, i ran prime for like 12 hours and occt for 1 or so plus benchs and stuff (cant remember precisely it was a long time ago), for me that was enough and so far everything worked fine.

i guess it depends on the programs you are using to stress test, some may require less others more, but i rather stress some more than risk data corruption thats for sure.

and unless you are messing with oc and testing in a daily basis i dont see how could you reduce the chip's life that much with just a few stress sessions.

12hrs of continous 100% load on all 2/3/4 or 6 cores and then 1 hour OCCT 100% load again + others. How much of that continous 100% load on all cores would you really rack up in a daily day to day bases or more over, how long would it take for you to achieve that amount of load? Data corruption could come in many forms, Raid error, memory failure, corrupt windows, virus etc...

I agree with your pyra, my point was just to casual users like me who enjoy surfing the web, emails, gaming etc as many noobs like myself always here things like stress test for 12-24hrs etc.

Is this a warning? or a RANT????
Is this a warning ?( or your opinion)
Is this based on fact or? ( or your opinion)

My interpretation of this !!!

your overclock wont go over 8hrs prime without BSOD

Uuuhhh leme guess.....My Opinion duh.

Regarding your comment in quotes 'your overclock wont go over 8hrs prime without BSOD'. Now ....

YOU MUST BE BORED and should charge for your foresight abilities
. .no not every1's as perfect as you. This is something which 'I' think is true and thought I should pass on to new overclockers as a bit of a advice but the final decision is truly theirs.

Does your CPU crash at idle too? Thought only MSI had that problem.

Haha when they warrant it for 3-5 years they expect full usage out of the CPU. Not every user is a grandma checking her email even if we push out systems hard. GFX designers encoders all push their chips hard everyday and get along just fine.

It seems like if you were just using your computer for web surfing and e-mail, you wouldn't need to overclock that much?

But yeah, I agree more or less. The best test in my experience is to use the computer for it's actual purpose and see how it holds up. A few times, I've had BFBC2 expose an unstable OC faster than stress testing with Prime95 or OCCT, and if I try to fold with an unstable overclock, I find out pretty quickly. I guess the idea behind long stress tests is that it's better to waste 24hrs stress testing and find a crash than to lose a few hours of actual work to find a crash.

If using prime95 for your stability testing 2-3 hrs is not enough.

prime95 blend test does primary small FTT for the first 12 hrs than large FTT tests start around the 12 hr mark.

IBT and all the other stress testers, yeah a few hours should be fine but not for prime95.

I would say you could get away with 2-3 hrs both on small than large FTT using custom tests.

If you OC your NB you need to run the large FTT tests. I'm sorry but the chance of a corrupt file isn't worth it for me. I lose my files, I don't get paid.

Truthfully if it doesn't pass a full prime95 blend (with it prioritized high) for 24 hrs, you have a slight instability. Most people can get away with it but it will eventually corrupt something (maybe a few years down the line).

Folders and gimps users do 100% 24/7. And I have had a system error at 18 hours, so yes more than 2 hr. is needed.

I used to think the same thing until one day my stable overclock bsod when compressing a big file. Now I test more but I agree people can go overboard.

I test with Linux and will do 3-5 hours of mprime (prime95). LInux seems to ferret out issues more quickly, I had a dual boot machine that would test stable for hours in windows and then crash when opening chrome in LInux. So far that has worked fine. Beyond that I'd rather just test it in normal use.

I fear all the overclocked folders who aren't stable.

Folders really need to do at least a 24 hr stability run (I would do 48).

If you have a slight instability, you're probably folding bad information/sending back bad information.

All it does it put projects back with bad calculations.

Please note folding is not a stability test.

You could be sending them bad calculations.

in my opinion 2 hour stress small FFT's is more than enough + 1 hour of BC2
