Default How to overclock?

I wanted to know how to overclock the CPU.

Firstly I know this:

you change your frequency like this:

Core ratio: 46 => 4.6Ghz.

But how should you change your voltage in relation to core ratio frequency?


4.6Ghz -->1.275V
4.5Ghz --> 1.255V
4.4Ghz --> 1.245 etc.

How do you know what voltage to change to, for stability, in relation to the frequency set? I know voltage increases temperatures. So I guess the moment it wont boot you increase voltage?

Every CPU scales different with frequency and voltage (primarily Vcore), so there is no universally correct values for everyone. You have to test for yourself, how much voltage your CPU actually needs for a certain frequency/ratio. The necessary voltage increase to go up the next step will eventually get a lot bigger and at some point load temperatures might become an issue and ultimately your limit. Also there is a huge difference (voltage wise) from being able to POST at a certain frequency and actual stability.

To get a grip of the overclocking basics i would suggest reading a few tutorials on Skylake overclocking. Then if there are still things you want to ask afterwards, you are of course free to do so right here.

I will do some extensive research before even trying to overclock. I don't want to damage my CPU. I can use this thread as my question and answer thread.

I have 1 question tho:

How do you know it is unstable? I know that if temperatures are too high, that means I must lower the voltage, right? If I go 4.5Ghz, at 1.22V-

What I learnt so far. you increase frequency to say 4.5 Ghz. Set volt to say 1.275V if unstable, add another 10mv, if it passes but too high temps, you lower it by 10-15mv.

So you just test like that? Btw, how do you know whether it is unstable or whether it passed? Will it crash if it is unstable? And if it is unstable, how do you know it is undervoltage, or overvoltage?

So, if undervoltage - unstable - low temps - fail --> increase 10mv.
if overvoltage - unstable - HIGHER temps - fail --> lower by 10-15mv.

So if overvoltage: high temps / fail.
undervoltage: low temps / fail.

But say your CPU fails the test, the way we know whether it is because of undervoltage or overvoltage is because of temps?

I'll start with 4.4 Ghz overclock.
