Cpu overclocking and lifespan

post #1 of 16
Thread Starter 
Hello everyone, newbie here.

I searched for this and the most frequent response is that you certainly reduce lifespan but it wont really die anytime soon. However it is also a fact that too much voltage is going to fry the cpu.

I was looking forward to overclock my old phenom x2 550 be and I reached 4ghz @ 1.45v and most people say that this is acceptable long term.

So what I'm asking is this. Can you post your build, your overclock and how often do you use your pc w/ cpu loaded? Also incidents of cpu deaths.

If this has been already asked, sorry and please delete it.
Sorry for my bad english too.

Cheers

The only issues are if you go above the recommended voltage the CPU will degrated. IE it will require more volts to hit that frequency. Running under the limits you will be fine. You'd need to do 1.6-1.7 to start to even consider damaging the cpu.

The short answer is no. And even then, the CPU would be the last thing in your entire computer to degrade. (your motherboard, GPU, ram, PSU, etc. are all going to die before your CPU).

Doing it properly, there shouldn't be any damage.

Ok slightly off topic last question. I have an Asrock M3A785GMH/128M (I guess 4+1 phases) rated @125W. I calculated my current cpu tdp ~130W. Should I keep it? (I want it to last for maybe a year or two)

i7 920 @ 4.0Ghz. OC'd from the start though IMO my voltage bump is pretty low (CPU-Z shows 1.24v). CPU almost 3 years old.

I've overclocked my CPUs for years and use my computer for hours each day. Can't remember the longest I've owned a CPU, but usually wind up keeping them for 2-3+ years or so. Never had one die on me yet biggrin.gif. I don't run full load much these days, but I used to do a lot of video encoding on a previous OC'd CPU (longest encode IIRC was 20+hrs. Gah,took f o r e v e r). Pretty sure that CPU was a little older than 3 years old when I sold it. Sorry, but can't recall voltage. It was more than this on a relative basis, but still clearly under any recommend OC voltage limits.

Still running my 5 year old Q6600 at 3.2 ghz all day long. A friend now has it, and he never shuts the thing off.

I've often wanted to know about this. I use my PC for work as an animator/illustrator and sometimes I render animations for long periods of time (anywhere upto 48hrs at a time, but mostly 6-12hrs). If I was to OC my CPU I could decrease that time, but I've often wondered if it is worth it when lifespan and degradation are concerned, as this PC has to last me 3yrs minimum (1yr old atm).

Maybe overclocking without increasing the voltage and seeing how much I can get without changing it would be a good idea? Might be a good idea for the OP if anybody else can back up my theory?

My old Q9400 was able to be undervolted while simultaneously being overclocked and still remained stable.

Essentially went to 2.66Ghz to 3.2Ghz, improving performance by about 20%, while making it cooler, and yet last longer. Technology is great like that.

If you go into your computers BIOS menu, and bring up the multiplier a bit, nothing bad will come of it. Only faster.... And you ARE on OCN.. The pursuit of performance, we can help you. you should be able to go to 4.2-4.5Ghz without raising voltages depending on how lucky you are. Remember to make that your stock and to turn off turbo! thumb.gif

It's super easy and fun.
