Voltages killing chips... Fact or fiction?

[r9]

I would say its a slow painful death, but not seating the cooler properly is instant death, so heat and dumb people are the main enemies.

LOL

 

[r9]

I read somewhere that 10 C cut the life of the CPU or GPU by half. The only problem here is that nowhere is written actual lifespan.
Most of as here are changeing their CPU 3-6 moths the rest in 12 months so lifespan not worryng me at all.
My question is are there people on this forum that killed their CPUs, minus kills that involve heatsink murders.

 

[lemonadesoda]

^^ Yes, most kills are heatsink murders.

However, for the halving of a CPU's half-life, what tends to happen is that an overclock (that was stable) becomes unstable. Dialling back the clocks to stock often fixes it. The CPU still works at stock, but is NOT the CPU is was when younger. It can no longer manage the OC's of youth.

Though actually voltage at a chip is not the best it has been shown that it is not the voltage at the CPU that kills them, but VTT or voltage on the FSB that is killing or degrading CPU's earlier than normal. Heres some prof for yas....

That shows nothing but VTT voltage can kill a cpu. Anywhere power is, power can do damage.

voltage is potential energy, the movement of electrons is current. Voltage does not flow nore does current. The shit isn't water. LOL
I'm going to take an educated guess at this one.
knowing that you have say 1.5v of potential energy at the CPU, and specific amount of current/amperage to opperate.
Also knowing that with the increase of resistance you increase current/amperage.
So the faster you clock your chip the more potential energy you will need to sustain those clock speeds. That being said when you increase the speed of the processor you increase resistance which inturn increases current/Amps.
Voltage will not destory a chip as I can apply 480VAC+ to a 18ga wire and nothing will happen. Now if you apply 100amps to that 18ga wire it will melt. The same thing is happening inside your processor.
You need higher potential energy/ voltage to sustain higher clock speeds, the draw back to this is when you do actually clock your cpu higher it will increase current and raise the temps.
Hope this isn't to confusing as this is a very hard subjuct to explain since their is so much more than just this involved with the process. This is just the basic's of what is actually going on.

While you make some points it doesn't quite work that way..
Set your chip to 1.5 volts @ stock clock and check your temps, then back the voltage back down to stock and check your temps..

Lets put it this way, put 500psi of water pressure in a standard garden hose and see what happens.

what does you mean by "That being said when you increase the speed of the processor you increase resistance"did you mean the cpu has the variable internal resistance ?

 

[r9]

I have a question. I have E5200. We all know that 1.37-1.47 jump is noticeable improving the OC.
Well my chip does not behave that way. At I`m getting stable 1.37 volts = 3.75 GHz . In short when I raise voltage 1.42+ it is becoming unstable at 3.75 GHz and you all would say that temp is problem. Idle temp 30-32, normal work 40 load 50+. And it is behaving like that from the first moment so it was not overvolted before.

i killed my Q6600 with voltage after 10 months... it was always watercooled so the temps rarely went above 60C .

What voltages did you used.

And of topic please score yours mobo 0-10 I`m replacing my P45 neo3-fr (memory problem) with P7N sli platinum.

I have fried a few old 478 P4s clocking them when the temps were kept nice and cool.
When electronics use more power then they were intended to use you damage them.

I new I would confuse some people, thats not the correct analgy at all bro. Lets put it a simpler way. Voltage is the cause and current is the affect. You increase voltage and the affect is more current. Current and resistance create heat. Not voltage, voltage is nothing more than potential and potential energy.

No it doesn't but when an overclocker gets his/her hands on a cpu it does in a way.
The faster a transistor operates the higher the resistance, like I stated above in a little more simpler form of cause and affect.
Higher the resistance higher the current higher the heat output.
Sorry everyone this is honestly one of those subjects that you literally have to write out an essay to explain correctly as there is so much involved it's isn't even funny.

im going to throw in a cure ball here, im working on the thought that watts = voltage * amps (150=240*.625) so in theory couldnt i just run my cpu off of 240 watts and some how get it to use 0.1875 amps (45 watt cpu) or is amps what the cpu actualy draws off of the voltage creating the amount of watts used???

 

[niko084]

I know exactly what voltage is, my whole point in it was the question does increasing voltage damage your chip, and the simple answer is yes...

I'm trying to keep things very basic and simple for people so they can understand. Many people here have a good understanding of computers, not electrical systems and how electricity works. I didn't really see the need to get into deeper aspects.

You seem to understand this, and from the last line you know it can become a whole lot more complicated to try to describe in detail... I mean we are talking about taking people through the first year in electronics here..

Amps = Current , Volts = Rate at which that current flows, Watts = Energy

So yes you could indeed do that, but there are problems there as well. Again quite complicated to get into the details.

Here is some food for thought-

Should help clear up for those that are more interested in the in-depth answer.
Remember as your overclock your cpu requires more energy.

 

[Woody112]

or is amps what the cpu actualy draws off of the voltage creating the amount of watts used???

amps is not drawn off of voltage at all.
amperage is the intensity of current.
Current is what the CPU is requiring to run at a given speed.
Cause and affect again when you increase voltage "potential energy" you increase current.

Good find bro. Was running out of way to explain

We All Know That Increased Voltage = Shortened Cpu Life.
What We Don`t Know By How Much.

 

[niko084]

What We Don`t Know By How Much.

That's because there is no easy answer to that... It depends on your voltage fluctuation and even more so the use of your processor, is it always running at 100% or does it rarely see that.. Then we can throw in the fact that while some chips may burn out in 5 years, some may last 20+... The basic idea is if you do a decent clock with what is generally considered to be a safe voltage and keep your temps in check, your chip should last until its no longer worth anything to you anyways.

 

[r9]

What we need are real life examples of overvolting and shortening of life.
The thing is when we get those in year or two it wont matter.

We don't need examples... We have people with strong backgrounds in electronics here to answer these questions and we don't need to do independent tests to prove it to ourselves. Physics is physics and nothing is going to change that.

I agree, and didn't mean to flame if I came off that way bro.
Your 100% correct with the simple answer of yes.
