How long will CPU last?

post #1 of 15
Thread Starter 
Hey guys I need somebody who has alot of knowledge on CPU's to answer this question....

I understand cpu's are meant to last about 10 years and when they are OCe'd they are likely to last alot less than that.... I'm planning to finally OC my 3.0E E0 stepping to around 3.75-4.0ghz with raised voltage! My computer is on around 8 hours a day with around 2 hours of the time being in full load.... About how long will my cpu last if infact on stock settings it is made to last 10 years. I'm hoping 5+ years.....

As long as your CPU isn't going over it's rated thermal output you'll be fine and can expect the same life as if it were not overclocked.

Depending on how much vcore you give it and the temperatures it will vary massively. I had a 3000+ winnie die on me after only a year from lots of volts and not keeping the temps under contol. I am thinking I got a little unlucky with that cpu as the 3000+ venice is still going hard with plenty of vcore and a 1 gig OC. As for the 3200 and the 144 we will see.

Thermal output as in temperature? Mine is 69C max I think... But isn't giving it more voltages and making it work harder going to reduce it's life?

just keep it cool enough and under the max voltage
(you might have a little space with the voltage level)
it will last just as long

and you wont have to buy a newer CPU for a while

The max temp you should be aiming for is around 67c which is where thermal throttling kicks in. I keep it under 60 to be safe and for peace of mind.

Technically it would, but by the time your CPU dies you probably would have to upgrade anyway just to keep up with minimum system requirements for software.

increasing voltage will decrease the cpu life due to the electron migration effect. just think of it this way, as long as you keep it cool by the time the cpu die new technology will already be out.

edit:what i meant to say is that electron migration effect speed up faster, since its already happening lol

You would think so. Duty cycles are how I believe projections as to component life are made. I may be misinformed, but I am under the impression that raising the clock speed increases the number of duty cycles per hour, min, sec and would thereby decrease the component life in terms of calendar time, not amount of work performed--the CPU is working faster, performing more switching and charging/discharging per annum, so it should reach the end of its life sooner.

However, my knowledge of what exactly deteriorates transistors and complex chips is spotty. Heat of course will cause quantum tunnelling which can cause instability and the BSOD--does Quantum tunnelling casue permanent damage? Over-voltage could probably melt or otherwise physically damage the component--but at what point does a stabilizing voltage become a dstructive one?

We need Ropey in here to answer these technical questions....

Sorry but I kind of like keeping my computer even if new technology is out...

Can anybody give me a number? YEARS?

I don't think you'll find the answer for that here. Most people here usually upgrade every couple of years or so.
