Overclocked CPU lifespan

post #1 of 6

Thread Starter 
I was wondering if overclocking significantly shortens the lifespan of CPUs.
Im just looking for a really vague percentage or what not just to get an idea.

I have an E5200 overclocked to 333 by 10.5 (originally 12.5 by 200) running at 1.368v.
I ran 6 hours of prime and the highest temperature it reached was 58 degrees and idles at about 32 degrees on both cores.

It doesnt have to be specific to my computer because im just looking for a general idea of how long the lifespan of my computer will be before it starts dropping.

All CPUs are effected by Electromigration, and heat can shorten a CPUs lifespan as well. However, even overclocked, it's unlikely your CPU will suffer any adverse effects for years to come, probably the better part of a decade. A couple years down the road, your overclock might become unstable and you'll have to give it some more voltage or lower the clock, but you'll probably replace it before it becomes an issue.

If the normal life of a processor is 15 years, overclocking might drop that lifespan down to 14 years 50 weeks, or 14 years, etc.

In most cases, the processor will be far out of date / out of your hands / replaced long before an overclock has a chance to kill it.

I still don't understand how i'm damaging my cpu

I'm running at less volts that the VID calls for and my temps are alot cooler than the stock cooler would run it at stock.

How am I damaging my cpu

Depends entirely on the severity of the overclock. Running at stock voltages should not lower the lifespan at all, and lowering voltages could increase it. That said, CPUs are supposed to have a lifespan of 10 years+ I doubt you'll care much for that shiny new CPU in 10 years time.

10 years ago Intel broke the 1Ghz mark with their P3. Would it be a tragedy if your P3 rig died today? Unlikely.
