Overclocking to 4.6GHz on an i5 4670k

[Backtothere]

I want to aim for an overclock of 4.6GHz but I do not know what to change to get there and how to fine tune the overclock to save heat and power. I know that other people obtained these stats:
CPU ratio: 4.6
Core Voltage: 1.220

I do not wish to go flat out and risk burning my PSU out and I am aware of the "luck of the draw" effect with overclocking, so what do I change first to reach a safe, stable overclock hopefully at 4.6GHz?
Also should I be changing the CPU Ring Voltage settings and overclocking my RAM?
My specs:
CPU - Intel i5 4670k
GPU - EVGA Geforce GTX 770 Superclocked
MOBO - Gigabyte G1. Sniper 5 Z87 motherboard
RAM - Corsair Vengeance 8GB Dual Channel DDR3 1600Mhz
PSU - XFX pro 750W, minimum temperatur
Cooler - NH-D15, minimum temperature - 29 Degrees, Maximum temperature - 52 Degrees

4.6ghz on the i5 is nothing to get too worked up about. Just set the voltage to auto and set core multiplier to 46. Run prime95 to confirm stability and monitor temperatures. The limit for throttling is like 99C but I personally don't like seeing my CPU go over 70C~. So my advice would be to dial back a bit if temperatures are too high or you reach instability.

He should not run automatic voltage voltage when running prime. It sucks up much more voltage than it needs, and is not that good for the evaluation of the overclock, as it also adds more heat.

In my opinion, he should try a quick and dirty way, and from that be precise.
Start with 1.225v, try raising the multiplier to 4.5, if unstable, add voltage. If too hot, less voltage. When you find your sweetspot lets say its 4.4 on 1.2, because you maybe needed 1.25 for 4.5/4.6, try to lower the voltage until it is unstable, then take your last stable voltage and have it there.

Try find out what batch you have your cpu from, and then search for the batch, and overclocking with that particular batch. Should be more precise than "most people get 4.6 on 1.22, so mine should do it".
Of course some from the same batch should be a little bit different, but not by much.

So is 1.25 too much voltage for an overclock?

Shouldn't be, no. I have mine at 1.245 volts for 4.4GHz.

Sorry for bad explaining.
The point of it was, that you would have to add maybe .1 volt to get 100mhz more, or 0.05v. Nothing is wrong with that, but 1.3 is what i would say max volt should be.
1.25 is a good starting point, but lower it if temps is becoming a problem

Alright so to overclock, I should turn the voltage up to something like 1.25v, if it is still cool enough raise the multiplier to 4.6 and if it then doesn't boot maybe go down to 4.4 then fine tune the voltage?
Or is that Dangerous and I should be going for 4.4 on 1.25v and then if it runs try raising it up to 4.6?

A overclocking guide. Should explain most of it.

Try 4.4 at 1.25 v. and see if that works. A quick and easy test is the Intel Burn Test on High setting. If it passes IBT for 10 passes, then it is safe to go higher, say 4.5 GHz. If IBT crashes, increase your Vcore in 0.010 v. increments up to a max of 1.300 v, then rerun IBT. If you cannot pass 10 passes of IBT at 1.300 v., then back down your multiplier until you do.

Here is a thread which helped me to get to 4.6 GHz: http://www.tomshardware.com/forum/id-1722630/intel-god-quick-dirty-guide-4ghz-haswell.html

The Intel Extreme Tuning Utility is a handy program to use for quickly changing CPU multi. and Vcore without rebooting: http://www.intel.com/content/www/us/en/motherboards/desktop-motherboards/desktop-boards-software-extreme-tuning-utility.html
The IXTU program will not do anything "automatically". All changes must be put in manually, just like in the BIOS. However it saves time that would normally be spent rebooting and entering the BIOS to make simple changes.
