With some new found research regarding dynamic cores and input voltages, lets try again for 4.7ghz!
1hour stress testing of Intel Extreme Tuning Utility
1hour stress testing in Asus Real Bench
4 loops of benchmark with all ticked
Registered volts in stress testing
Core : 1.333v
VCCIN : 2.150v
Ring voltage : 1.285v

Mine does 4.7Ghz @ 1.235v - Your chip is not the best overclocker
Nope, however some can't get past 4.6ghz! But as I said as long as it did the same clocks as my i5, i'd be pleased
Going to try for 4.8ghz when the weather cools down and after new paste

At stock it will have been faster than your sb i5 at 4.7ghz. Found my old 4.5ghz 4770k matched 2700k chips clocked around 5ghz.
Good to know! Cheers Setter

Id suspect mine would be similar. 4.7 though is more than enough for my uses. What sort of temps in game do you get with the triton cooler Neil?
Games about 60c in BF4, perhaps lower depending on the game. In stress testing highest at the moment is about 80c MAX
Ambient temps are at 27c
Caporegime
Pretty good that, mine was anything from 60-75c max. But that's from when I had sli 780 non ref cards heating up the case. Yet to game for an extended period with the single 980ti.
Interesting, I thought I'd try a higher uncore at 4.5 instead of 4.0-4.2, within about 5mins a complete freeze up during stress testing ( Unlike hours of stability from before ). So now I've put it back and now trying a lower voltage across the board.
Once the weather cools down, I may try an uncore at 3.9 with a main core at 4.8 and see if it makes a difference

Just keeping an eye on my temps and this h440 is awful for cooling 
my h105 is barely doing anything.. May have to reset it or something

Oddly i can't get anything above 4.7Ghz on my chip. 4.7Ghz @ 1.235v and yet if i put it to 4.8Ghz i can't get it stable no matter how much voltage i give it, i can only guess i need to adjust something else.

The law of diminishing returns certainly seems to apply to these CPUs, throwing voltage at them just doesn't work. It is amusing to watch the process that we all go through, trying to get over the 4.7 GHz cliff, before finally realising the extra 100 MHz is completely and utterly pointless and undetectable in anything but benchmark suites.
Better just to throttle back to a much cooler 4.6 and enjoy the fact that these chips are still plenty powerful for anything most people are going to use them for. Even those that claim stability at 4.8 GHz and above still mostly seem to run at lower speeds once they've got over their initial excitement, which makes me wonder if they're benchmark stable or 24/7 stable.
That said, the fun has gone out of overclocking for me with this newer stuff. Nowadays it's almost totally a lottery and no amount of skill or voltage or fancy cooling can make as much difference as it used to.

With these later CPU's, it seems many of them are stuck at a wall of 4.7ghz, mine is the same, as is someone else's I know
True, I leave mine at 4.7.. However it would be nice just this once to have a 4.8 chip as my i5 2500k was at 4.7 too

I've owned two 4790k's and 4.7 has been the limit in both for sensible 24/7 voltage and temps. Previous owner benched the one in sig at 5ghz but it needed very high voltage to do so.
