how likely is it to kill the cpu

[EzNoW]

how likely is it to kill the cpu when rasing the vcore because im overclocking my p3 650 and it wont go past 118mhz fsb i think ill need to raise the vcore to go further is it safe, can it kill the cpu straight away

If you get crazy you could fry it instantly.

Take it slowly. Raising the vCore will shorten the life of the CPU.

[nomis_nehc]

well, there are obvious numbers that you should just stay away from. but generally, from my experience, staying within 1.85 or so without mod should be fine.

[spacey]

actually i think a more accurate answer than simple vcore shortening life, is rather heat shortening the life of your cpu. you can raise your vcore all you want if you can keep it cool, but generally this is hard. so what you should be asking is how hot can your cpu run safely?

to be honest, i think cpus can take pretty high temps pretty well. if they're under 50 deg you're pretty good. even if you were to go to like 55 deg or something, so your lifespan goes from 10 years to 5 years... i dont think its worth being too concerned about, most ppl get new computers every 3 years anyway. your cpu is already old so you might as well get the most out of it.

i concur, its not the volt, its the heat that will inevitably will shorten the life, key is if you keep the heat down the cpu should have a normal lifespan. my rig runs @ 25c idle and 32c load with is below normal however am clocked 2.8c @ 3.5ghz

Altho i agree with every1 that it's the heat is Public Enemy #1, sending more volts thru the tiny transistors inside the CPU doesn't do it any favours. :no:

The main problem is you can pretty much tell what damage heat is doing with sensors and cooling and stuff... how u gonna tell if u just fried a few 0.13 micron transistors??

On the flip side, as long as u don't go crazy most CPU's will last well beyond the point u find them slow, dull and in need of upgrading so i wouldn't lose too much sleep!

At the end of the day it all comes down to choice. Red pill or blue pill? Play it safe and respect the silicon shrine or go full force assuming you'll upgrade soon anyway.

well..my heat is no problem :) when idle i reached a temp of 15 degrees (more often just 18)...and when in full load, for about 1 hour, i reached the 24degrees....and i'm running a 2.6Ghz @ 3.3Ghz i just think i should cool my northbridge to :p it's just a heatsink now...@ 40degrees or smth

god i just love my watercooling :p

but isn;t raising your Vcore mostly ment to stabilize your cpu speed? not to accelerate it?

currently running a barton 2500+ at barton 3200+ speeds in a shuttle systems, temp at 50 - 52 C, and i cant see that being a problem...

I raised my duron vcore from 1.6 to 1.85 instantly, and i have it running at 850 (750 stock), it runs at 21 degree's cel at load. i havent had anyprobs with it. it seems alittle stablier, but not that noticable.

[Ritalin]

it's just bad on the long term i guess...

[Zip]

but isn;t raising your Vcore mostly ment to stabilize your cpu speed? not to accelerate it?

it allows you to increase your overclock and keep it stable

well yea but it's the voltage that CREATES the heat. hence people saying that vcore kills the cpu. but everyone is right, if you can keep your cpu cool, you can go as far as your psu will allow. i have a friend that went to 2.26V on his barton. personally i don't touch 1.9V. i don't have enough money to risk that kind of a thing.

BTW... nice temps. way to make me jealous! jerk face! :D

[wstokeley]

i agree with generalstupid. I wouldn't dare go higher than 2v, and i wouldn't even consider doing that. Remember any speed increase you get will not be that vast.

[lostspyder]

Its not realy the heat that kills a CPU, its electrons jumping the little gaps in the proc. Once an e- jumps it preatymuch burns in a bridge and others follow hense the proc is dead. Both heat and voltage increase the probility of this. If you raise the voltagem, the diffrence above one of these gaps is going to increase, and the electron will be more likley to jump the gap. Heat also has an effect of 'loosing' everything up. Of corse if your proce gets up to 90c its just gonna send out pumes of smoke and you can screw the whole electron theorie.

As for raising the vcore, you can preaty much send it up to 2v and have it last a minimum of three years. After thoes three years, youll be able to buy a faster proc for like 50$. It will barley set you back for the preformance increase you recive.
