Undervolting and stability testing?

I read that stability test should be run for like 3 hours when reading the guide on undervolting..

I am wondering if maybe that info is incorrect? I know people probably (generally speaking) get a bit more aggressive when overclocking and want to tweak more settings..

However, 3 hours seems like a very, very short time to stability test.. Especially compared to OC stability test which run for 24 hours before a component is "officially stable", is there any reason why there is such a drastic difference in the time of the test?

 

I use orthos to stress test. I usually starts with a high Vcore and then lower it every minute until either orthos stops with a red background in the 'status' area or my laptop freezes. With the red background I just up the voltage a bit (for instance from 1 to 1.0125) and run the test again for about 15 minutes. If orthos doesn't stop again I know that 1.0125v is my stable undervolted voltage. I usually up again the voltage to 1.0250v just to be in the safe side.

P.S. undervolting program RMClock with Core 2 Duo CPUs.

 

Like you mentioned, 3 hours is not enough for a stable overclock. Actually "stable" is a bit of an undefined realm. For practical applications on OCing or undervolting, something stable is anything that can last longer than your normal computer use. Hence why for OCing 24 hours means stable.

I hope I was not too confusing.
