Stress Testing Warning

post #1 of 113
Thread Starter 
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!

50 passes of Intel burn test at the maximum setting are enough for me

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.

sometime prime 95 show error after 6 hours of burn test, i dont understand some guys just test their oc for like 1-2 hours and then called it stable.

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...

^^Sushimaster^^

Would you really use all your cores with a load of 100% on each core for 6 hours???

I stress mine for 4-5hrs and if it passes I'm happy with it, never had any problems with only stressing for that long.

but, the guys that fold do need perfectly stable CPUs.

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 ....

Is this a warning? or a RANT????

My interpretation of this !!!

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.
