overclocking endurance

[almerac]

ive been wondering, as much as i have looked around i have not found alot about how much overclocking decreases the life of your proc. so i was wondering if the overclockers out there wouldn't mind posting what overclocks they have, and how long they have been running them at, with whatever voltage. i dont mind, if its only been overclocked a couple of months, but i would prefer to hear from people that have had stable overclocks of at least a year, and up until the proc burned out, or even if its still running steady.

thanks in advance

what do you mean exactly? like keeping the voltage to a reasonable amount? heat? combination therof?

How long are processors made to live? 7-10 years? Im only asking because I'm wondering how much electron migration I would get for running a heavily overclocked processor for about 2 years.

Is electron migration even a problem to worry about when overclocking?

oh yeah and what exactly is electron migration?

Is when a semiconductor wire has more current density than it can handle. The it deteriorates according to the amount extra current.
The most practical example I've seen was when Shamino run his HZs (DDR2) @ 3.2v for about a full day. After that it had lost 5Mhz, the modules needed a higher voltage to remain at such speeds.

CPUs are design for 10~12yrs, thats why we can use really high voltages on them. There actually isnt a cap on what you can use. But there are always 'safe' voltages which are the recommended for 24/7 operation, ~1.45 on a C2D will last you long enough for you to move on from it.

well that's reassuring. I knew it probably wouldn't be a factor as I would only dream of keeping my C2D processor for about 2 years or less and my graphics card even less than that.
