CPU'S lifespan tied with overclocking

post #1 of 27
Thread Starter 
everyone says that your cpu lifespan will always shorten with overclocking and over-volting of your processor, and iv'e always believed that too because it just makes sense. BUT ive had my cpu(q6600) overclocked and overvolted for the past 3+years and its still going just fine. before this, i had a pentium d 805 that was oc'd for over 2 years and still worked just fine. has anyone actually had their cpu die after long use and overclocking?

It depends on how much voltage you give it and how hot.

MOST oc'd cpus should keep going and going like normal, but every once in a while you hear of someone's cpu just dying unexpectedly. I guess its just luck of the draw and batch # etc.

I think its more heat thats an issue. more volts have a minimal effect.

Never had one die, but a few times had to lower the OC as it wasn't stable anymore. Had an Athlon II x4 that was stable at 3.7 for like 4 months, then couldn't do it anymore.

Overvolting should reduce lifespan, but I have seen 15 year old cpu's running with no problems so... if you lose 10% of the life span your still going to throw out your computer long before the cpu dies, (hell you could lose half and it wouldn't matter)

Heat would be the main reason from it killing over. And unless you're just trying to push as much voltage in it as possible then that would do it. Long as you keep it cool then it should be fine.

@ Win == True, 15 years, well i guess we got another old guy to add to the OCN Old Guys List then.

Besides some early 32nm's/gulftowns that died at 1.5+V, the only chips that ever died from being moderately overvolted were those pentium 4 northwoods; some degraded severely, some died. (I had one that used to do 3.9 ghz at 1.7v, degraded badly to the point where it only did 3.4 ghz at stock, and would freeze in POST at 3.6 ghz).

As far as newer chips, it's hard to say.
Some chips degrade slightly (0.025-0.05v) then work continuously from there. It seems that low vid, high leakage chips (higher heat?) respond more favorably to vcore than cool, high vid chips. I don't think anyone has tested it yet, but I wonder if cool high vid chips degrade more than hot, low vid "leaky" chips, since the cool high vid chips don't respond as well to voltage? No idea about cool low vid chips...

This is why I don't like to push my Cpu too much. heh.. I've been running this OC since the day I bought it, almost 5 months ago. Its gaming stable at stock 1.3v but Prime95 says it needs the extra 0.025v. , so I kept it there to be safe.

My theory is every chip, ram/cpu/gpu, has a native speed and is downclocked to meet market demand. eg.. my CPU would have probably passed as a Phenom II 955.

@firebirdjimbo What model does your Q6600 scale up to ?
