Overclocking is one of those things that if you don't have the patience and can't understand, you shouldn't be doing it.
You have a 4770k, if you have a good video card paired with it, there is no need to overclock it, it will crush any game you throw at it, so don't bother toasting stuff and screwing up your system for a bit of bragging rights that have no basis in the real world.
I have overclocked since the Pentium I days, and it still took me over a month of tweaking to get my AMD chip to 4.86ghz, with hours of tweaking and testing each day.
My advice, be happy with what you have, it's faster than you need anyways.
