I got a reply on ASUS that they set their mobo's to give higher voltage than needed on cpus to insure the cpu to work always.

So I don't really know a lot of ocing.

What voltage do i need for 4.6ghz?
and for 4.8?

and what voltage is considered high? And If the voltage is high, how quick will the cpu break?

-----------------------

1. Tell the suitable voltage to obtain 6700k to OC to 4.6 GHz safely
2. Tell the suitable voltage to obtain 6700k to OC to 4.8 GHz safely
3. Tell when the voltage is too high to be safe EX: 1.425 volts will make your cpu break in 30 sec
4. Tell how quick the cpu breaks if the voltage is too high








THANKS!

every cpu overclocks differently

my personal choice no more than 1.4v as long as you have decent cooling

some people go higher than 1.4v but i prefer not to

rough guide 1.35v for 4.6ghz

1.4v for 4.8ghz if your cpu can do that high

1. Probably 1.3 but it varies with chip
2. Probably 1.35 or 1.4 (dont recommend unless watercooling)
3. Anything above 1.45 that lasts for more than 30 sec unless extreme watercooling or LN2
4. Can't really answer that as no testing has been done. It definently shortens the lifespan the higher than voltage, less life

MERGED QUESTION
Question from makeandbakeasandwich : "1.425 voltage for 4.8ghz on 6700k"

Is 1.425 volts not safe?

From which point of cpu voltage will fry the cpu on average?

THANKS I WILL GIVE U A SANWICH

How high you can OC is determined by how good YOUR chip is.
Intel puts a Max of 1.5v so probably no more than 1.4v is what you can tolerate over time.
As of 5/2016
What percent can get an overclock at a somewhat sane 1.40v Vcore.

I7-6700K
4.9 2%
4.8 17%
4.7 59%
4.6 93%
4.5 100%

I have been running a I5-6600K @4.8 and 1.4v since it was launched, but I have a particularly well binned chip.

You will not need much cooling, at 1.4v, only an air cooler with a 120mm fan is needed.

What you do want to do is to set your oc up so that the voltage and clock rate drops when the cpu is not under load.
Speedstep and adaptive voltage will do that.

then guess you got lucky and this questions kind of made irrelevant then as thats obviously a very safe voltage

I don´t believe it! .. Its most likely a "boot to desktop" voltage.. Throw a stress test, prime95 or high end game (GTA V pc) and I will BET it will crash!

Also why does people never mention Load Line Calibration and Current Capability! those are essentíal to a OC boot at all ... LLC is properly LVL 7 and Current Cap. 140% IF that 1.28voltage range would boot.
