Ok, everyone is trigger happy when it comes down to voltage...but! Getting higher temps is the only downside to increasing voltage. I mean, this is too easy, it must be something more...I don't know what, why don't you people try some answers.

Er, where's the question?

Higher voltage = higher temps = instability.

That is such a superficial answer. The question is: Getting higher temps is the only downside to increasing voltage???

Well if you go past a certain VCore you're gonna start frying your core but we're actually not really trigger happy on the voltage. Hell, I'm burning my Opty in so just I don't have to increase the voltage! It's not that big of a deal if you got water cooling but if you're running just Air, you try your best to get your OC on stock volts.

Ok, that is a good point, but that still doesn't answer my question, the cooling solutions we have in the present can very well handle any temp, no matter how big is the voltage... sooooo, what is stopping me, you anyone else (except money, of course) to get a better cooling solution and up the voltage some more...

MADMAX22

nothing, heck before runs dual phase or ln2 and he uses voltages up to 1.9 vcore, i have run as high as 1.75 on my amd chips under water and phase

just remember that at higher voltages even with sub ambient temps you can still damage your core and severly reduce its lifespan which is what most poeple try to avoid because they dont want to buy a new cpu every 6 months or a year allthough some of us consider a year plenty long enough for any cpu

it depends on what you want out of your system and how long you want it to last and really how much money you have to throw away on your computer

Higher temperature is only one aspect of overvolting. The other aspect is ELECTROMIGRATION. At the microscopic scale of processors, electrons can jump out of their wires. More voltage means greater chance.

Please tell me more about this lifespan reduction and why does it take place...

TheLegend

The more voltage being pumped through the silicon the more stress it induces.

Higher volts mean higher temps and as we all know that high temperatures are components worst friend. If you have adequate cooling the lifespan reduction is significantly lowered, but the more a product is stressed the more it will break down.

Your car is not meant to travel at 8000rpm full time. The same applies to overclocking to that extreme.

Electromigration..... not heat by itself kills processors when overclock (unless your cooling somehow critically fails). Higher heat increases electromigration. In layman terms, too many of the interconnects inside your processor tear.
