I want to get into overclocking but I don't want to screw anything up. I have a i7-8700k and a Corsair h100i v2. motherboard: ROG Z370-F. I was wondering what my voltage should be if I want to overclock my cpu to 4.7 ghz and what other settings should I change in order for my computer to work at its maximum performance. Sorry for the trouble but, I'm only sixteen and I wanted to get more information on this kind of stuff without braking my pc.
Well, in that case, I'd point you this :

This is a new guide to OC for beginners and semi-seasoned OC'ers. It's very useful, and I would consider myself a reasonable OC'er with many years of experience, and I've re-learned things I've forgotten. So I highly recommend it.
It's from a former Moderator and longtime member @ darkbreeze. I've had the pleasure of conversing with him, and he's a top guy!
From my own experience, I'd suggest researching what you want to achieve. Make sure you have the right components, are familiar with your BIOS, the hardware in your system, and their limitations. OC'ing is immense fun, a little tricky, but a great (and free) way of getting more performance out of your system.
With all of that said. You have one of the best mainstream gaming CPU's out there. You don't NEED to OC your system. It will perform perfectly well at stock speeds.
What GPU do you have? Your system as is, without knowing the GPU is pretty monster, and will handle anything you throw at it, and then some. If you were a semi/pro gamer and you just wanted more FPS then I'd say OC your system. If you are a casual gamer, and like all the bells and whistles, you already have one of the best gaming CPU's on the market to achieve that. So I'd worry about OC'ing further down the line. Like maybe 3-5 years!
When it could benefit you. Right now, you don't need to OC to achieve some benchmark score or 2 extra FPS (game dependant) from OC'ing. Just enjoy your system as is for now.
