What's the limit on CPU volts?

post #1 of 6
Thread Starter 
This probably has been asked before, but in general, is any voltage safe for a CPU so long as the temp remains within a reasonable range?

Depends on the cooler and the cpu you have

With your CPU and cooling i would'nt go beyond 1.4v,but if you change any voltage do it gradually and keep an eye on temps while you stress the CPU with Prime95 etc.Speedfan is pretty good and free.If your temps are not to high at the voltage you use you should be good to go further,but as a rule i'd say definately stay under 1.5v without damn good cooling.As long as you dont let your temps go over recommended you will be fine.71C is the max for your CPU i believe.

Just double checked for you.Your CPU can go to 73C.

As long as your temperature remains in a reasonable range you can put as many volts through it as you want. Just don't expect your CPU to last up to 10 years like a normal one would. It's not going to die, but remember.. as Wikipedia once said, and still says..

Lol,but unless he use's crazy voltages or lets temp's soar over 73C he's not gonna impact that severely.Basically if you want the CPU to last 10 years-dont overclock.If you will upgrade in less than 5 years-overclock within CPU's thermal envelope,could last 10 years still anyway.If your demented and just dont want your CPU-plug into wall socket and dis-regard temps altogether,lol.

Seriously though,overclocking done right will not effect CPU that dramatically,the girlfriend is running a crappy celeron 8 years old,not overclocked,but in a case she never cleans dust out of,i dare not look inside,lol,in a silly eMachines case with no effective ventilation as such,its still going.What i'm trying to say is by the time your CPU becomes defective due to overclock/high temps,you wont care,it'll be worthless,it might just about crawl round the net,but not much else.

Thanks for the answers guys. Yikes I didn't know 73 C is the max. Fairly sure I've been close to that before in the 66 C range. My voltage is currently at about 1.42, which translates outside of the BIOS to about 1.48-1.49 depending on the load. The funny thing about the stock cooler is it does ok up to a point but when you cross that point going from 75% fan speed to 100% fan speed makes 0 difference aside from a harrier jet landing in my case. The preface to the question is I'm getting an aftermarket cooler and was hoping to push my volts a bit higher, but I didn't want to do that if the temps are fine but 1.51 V magically blows it out.
