What should I set my voltage to for overclocking CPU

[Lewis_40]

I am new to overclocking and need help setting the voltage for my CPU.

My Rig:

i7 7700k - GTX 1060 6GB - 16GB Ram

So I am planing to set my GHZ to 4.5 - 4.8 and wondering what my voltage should be. Thank you.

The voltage can vary from one system to another and it's quite hard to predict one, so the best thing you should do is to search on the internet someone with the same Mobo+CPU that made a stable OC and copy it.
An OC to 4.5 GHz maybe not even need to increase voltage, so put the CPU at 4.5GHz and stress it, if the OC is stable, increase clock by 0.1 until the value you want or the OC get unstable. When the OC get unstable, increase voltage as minimum as possible (in my Mobo minimal increase possible is 0.020v) and stress the CPU, you're core voltage shouldn't be higher than 0.1v since this is a small OC.
The values I told you are my guess, for something more accurate someone that already made an OC on this CPU should tell, I never did an OC on this CPU.
