I5 6600k overclocking questions

Hello, (I am new to this)

I have a i5 6600k in a ASRock Z170 Pro4S mobo.
Last night I tried overclocking it for fun, tried multiplier x40 and it was stable but when I tried 42,46, 45 the computer wouldn't boot past windows :/

I benchmark the cpu using cinebench and it gives a score of 650.

My question is, is it normal for the Core Voltage (CPU-Z) to have variation? in Idle it's 0.768-0.8 and goes to 1.108-1.136 when it has load.
Also, is it normal that the Core Speed varies too? (It shows 800 MHz to 1800 MHz and in load it's 4000 MHz).

Other questions:
- What is EZ OC mode in the motherboard?
- Should I fix the voltage in the mobo? if so, how? there is an offset option but i'm not sure how it works.

Thank you!

You should be able to get about 4.4GHz on 1.3V.

The way to do it is first determine your target voltage in Manual mode and then use that voltage in your adaptive mode to let CPU SVID take control of voltage requirement.

I would not go past 1.3V for everyday overclocking.

It's normal and recommended to keep it that way. CPU uses the amount of speed/voltage it needs based on the load.
What is EZ OC mode in the motherboard?
It's auto overclock. I prefer manual.
Should I fix the voltage in the mobo?
Not recommended unless testing for instability when doing everything manually.

On adaptive/offset mode, CPU has a voltage curve similar to the fan. +0.010v would increase the curve by 0.010v
