How long will my cpu last when overclocked?

#1giglamesh99Posted 6/1/2012 7:36:19 PM
Got a 2500k, looking to overclock it to 4.0. What's the best overclock range and does it drastically reduce the life of the cpu?

Not the usable life, anyway. Maybe it will only last 8 years instead of 10.

upping the Voltage beyond specific points is what reduces life.

More likely it'll only last 12.875 years instead of 12.87532 years.

A modest overclock like that isn't going to do any harm. It's probably so far within the specifications of the chip that that it's more like not underclocking.

On the other hand, I could probably shave a year or so off my 960T by running over 1.5v to get that extra 100-150mhz or so it might get me.
I think I'm more likely to hit a OC wall due to my (not so grand) 8+1 phase design. I think I'm already running close to 140w with just 4ghz.

Even though the game runs in 720p, it produces another 480p stream for the New Controller. That's like 1200p!

So I should monitor voltage when overclocking? From what it sounds like, I should go even higher to maybe a 4.5. If I can get 4-5 years with no problems, I'd be happy

You might not even have to adjust voltage. I was actually able to overclock my processor and undervolt it slightly with 100% stability. Been going strong for three years.

I don't think you know what you're doing TC.
I would suggest you do whatever you feel is right.

Im pretty sure CPUs can last an upwards of 30+ years. unless you dawgs mean 10 year lifespan if the pc was on 24/7 for 10 years

Turn off auto-voltage if you're using it. Burntest to make sure that X voltage/clockspeed combination is good to go, and if it isn't, up the voltage or turn down the speed.
You're likely to hit a thermal wall before you exceed the safe voltage limitations of the chip. IIRC, Sandy's upper voltage limit is ~1.5v.

Thanks for info! I have Arctic silver thermal paste and a cooler master hyper 212 fan, should be good on heat end
