12 hours in prime and 50 runs in linX is my minimum standard for stability testing.. Both of these together catch unstable overclocks fairly quickly.. I'd feel better with 24 hours in prime, but I'd much rather be gaming than stress testing.

OMG who brought up the car analogy?

All high end car manufacturers stress test their motors before selling. BMW comes off the top of my head with their M series.

The manufacturers who don't have higher statistical motor breakdowns (in the same price/model range).

I wouldn't put a motor into my project car that hasn't been stressed tested. I plan to beat the crap out of the motor and I want to know it'll keep up. On top of the price/time for install/tune.

And for the poster above copied and posted from my previous post.

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).
12 hrs of prime95 is not enough. prime95 probably hasn't hit large FTT tests yet. The rest isn't for you, just wanted to explain why even after 12 hrs it can fail. You could try a few hrs in both large/small FTTs.

prime95 is not just for stability its for data integrity. If you don't need stable data integrity than fine, have a slightly unstable system. Remember data is worth more than parts for most professionals (no idea about the younger crowd, maybe once they lose their final paper they'll care).

IBT tests for stability is fine, but I wouldn't trust it for data integrity.

And why do some people seem proud to announce they fold without running 24 hrs in prime95? It only takes 1 day out of your life and you could be confident you're not sending back corrupt data.

No, over-clocking alone won't reduce your CPUs lifespan. Applying excessive amounts of voltage and running your CPU at extremely high temps. will.

Even then, I'm 99% sure that a well cooled Sandy Bridge at 1.4V will last more than 5 years.

I bet if you Fold it would detect an issue.

Also, to those people saying stress testing for 24 hours will cause damage to your CPU: you're wrong. The only instance in which it'll do any damage is if you're running an insane amount of voltage through your CPU, for example 1.5V for Sandy Bridge. The reason for that is, as you pump higher voltages through your CPU, its thermal resistance will be lowered. This is why many people that run at such high voltages then have to lower them quite a bit.
