What factor lowers a CPU's life.

post #1 of 9
Thread Starter 
Hey guys, simple question that I think y'all can om-nom through pretty fast.

What is the main underlying factor that kill's a CPU's lifespan. Consistent high voltage? Short-high voltage spikes? High ghz?

Also, I see a lot of people here for and against Load Line Calibration on the forums. However, a lot of the posts I see against Load Line Calibration are timestamped from about 1-1/2 to 2 years ago. I seems like more and more people are for it. Is LLC more reliable now? It seems like one of ASUS' main selling points today is the reliability of their DIGI+VRM. I have a basic understanding of how LLC works, so let me know!

Thanks!

high voltages and high temps combined will kill a cpu quickly . however, super high voltages will cause electron migration which will kill the cpu. Also high temps by themselves reduce cpu lifespan.

As far as Im concerned its Volts and Heat. Others have differing opinions but this is what I watch out for. Frequency, not so much

for sb, anything below 1.5

sorry, but 1.39v? get out of here.

as for what causes it to die? combination of heat and voltages.

Voltage and temperature. The higher the voltage the shorter the life, no matter the time it see's that voltage. Though short times at high voltage will be less abusive than longer periods.

Lol for 24/7 use you definitely don't want above 1.38. It is after all a 32nm chip.

It seems like the amount of voltage that sandy bridge can handle is a pretty subjective matter. I have mine running @ >1.35 for 4.6. Is there any input from Intel on the matter?
