4770k needs too much voltage?

Hi,
First of all, let me say I am beginner at overclocking, but I do know a few things. From what I understand, to overclock you raise the speed multiplayer until an error flashes up, then you raise the voltage until it is stable-rinse and repeat. Right? Well I tried to overclock my 4770k on an Asus Z87 Sabertooth with 8gb 1866mhz Corsair dominator platinum, and I needed 1.4 V for 4.2 GHz. I understand that is high so atm I've stuck it back at stock clock. I know some chips are simply terrible overclockers, but surely something isn't right here. It shouldn't need 1.4 V at 4.2 GHz, should it? What am I doing wrong? It's not throttling because I have a Corsair H100i and load temps are 60-70 degrees. Again, am I doing anything wrong?
Cheers

Are you manualy setting the voltage?
Manualy setting the frequency?

or are you using the turbo boost feature?

If you are willing to set them by hand try this.
100mhz base clock
42 multiplier
1.175v vcore

There is always the possibility you have a bad CPU but lets try not to think about that for now.

The above numbers are my 4770k oc numbers. I found out today I can get 4.3 at that vcore aswell however 4.4 is proving to take a bit more voltage.

Yes, I'm not at home now but I believe I'm setting the turbo boost feature to 4#. I think I am setting the voltage manually as it seemed to have an effect on the little overclocking I achieved

That is the problem right there. Don't do that. Overclocking and turbo boost are 2 separate things and need to be treated differently.

Myself I disabled my turbo boost feature and set voltages by hand, if you let the CPU do it in auto it is far too aggressive and adds too much voltage too fast.

The voltage that my CPU gave me in auto at 40 multiplier at 1.175 volts. In auto at 42 multiplier auto cranked it up to 1.375

I switched to manual control and dropped to 1.175 volts and hit 43 multiplier stable.

Use manual voltage and manual multiplier settings and it should help you out

Cheers man, I will test this when I get home and have access to my PC and I will report back on results. As I say I may be completely wrong and just have a terrible overclocking chip

Just tried 4.3 with the CPU core voltage set in manual to 1.175. Just got a error message. I've disabled all of the power saving settings and turbo mode :/

If it errors then drop your multiplier a bit, to 38 or 40. Overclocking is by definition pushing your system passed its factory designed spec and not all CPU's are created equal. You say you are a beginner so it sounds to me like you need to go back to the beginning.

#1- Take everything back to factory settings and stress test for a while to make sure your system is stable at factory settings. While doing this read a couple Haswell overclocking guides as well as watch this http://www.youtube.com/watch?v=0CHs5_TdpXE.

#2- Turn off turbo boost
#3- Manually set your vccore to 1.125
#4- Set your cpu ratio/multiplier to 36 or 37 for starters
#5- Load windows and stress test for an hour or so
#6- If all tests good then drop into your bios and increase your ratio a bit more, test, rinse repeat until you get an oc that your happy with

Below is my board with appropriate fields highlighted, Your UEFI may be different but it should give you a bit of an idea I hope.
