Does CPU draw volts?

Forum Overclocking : CPUs Does CPU draw volts?

Word :    Username :           
 

I was wondering when you up the CPU voltage, is it INJECTING that much into the chip, or are you just making that much AVAILABLE to the chip--like multiple car batteries and a starter?

So If I up voltage to say, 2v on a 2700k, will it damage it? Or will it only damage it when I've OC'd it enough to start drawing too many volts? Thanks.

Yes it really is applying that much, minus a little as there is a slight voltage drop before getting to the CPU, so don't set it to 2V :)

What it draws only when needed is current, more current = more heat and power, voltage is constantly applied unless using offset voltage setting.

if you overpast the max cpu power setting for voltage then you be good to buy another one

If you increase the cpu voltage enough, you will definitly damage it, perhaps permanently.

Each specific chip sample has it's own tolerance.

If you are a competitive overclocker, go ahead and see how much it can take.

If, you are a normal user, be sensible, and do your overclocking via the multiplier only, and let the motherboard auto adjust the voltage.

2 volts will fry it for sure. 1.3 is the maximum safe amount for sandy bridge chips.

So then, increasing the voltage increases the amount INJECTED into the chip...it doesn't just increase what is AVAILABLE. If I'm getting you guys right?

more voltage you increase the more go to the chip ,that is correct

1.52v is the absolute maximum to use, i'd recommend below 1.35v for everyday use, maybe 1.4v if on watercooling. temperatures matter a lot as well

Wow...How is this a valid question....Really....2.0 volts????? You gonna end up with a shiny new paperweight !!! Voltage is the #1 killer of components followed closely by heat
