Once you hit your limit (be it thermal, voltage or just stability) you can leave the CPU settings and start upping your RAM. There is a chance you can hit 2400MHz or beyond, but there also may be a tradeoff.

Example: 4.7 GHz @ 1.33V is stable with RAM @ 1600Mz. Chip will NOT OC stably past 4.7.
Now, up the RAM as far as you can until you reach an unstable condition. If you reach 2400+ MHz and are still stable, more power to ya! If not keep the RAM at a speed that is as fast as it can be without causing crashes.
This same RAM may be stable at 2600 MHz on a stock CPU clock but cause crashes with an aggressive CPU overclock. These CPUs have the memory controller on die.

And note that 4.7 GHz is like the upper 25th percentile of chips or something, so don't be mad at me if yours won't pass 4.0 GHz tongue.gif

^ like this.

With memory overclocked as you overclock the cpu the memory related voltages will need to be increased as you go, easier to get the cpu frequency set as well as it can be & then work the memory & uncore.

I just noticed these Benchmark charts for 4770K and how it stacks up...It surprisingly holds its own, and does pretty decently. I for one am surprised, nothing to be in "awww" about, but i thought it was interesting, these tests were done in June of this year.

Man I hate to be that guy, but if you get a cheaper mobo and ram you could get 780s for the same price.
