So I heard that disabling speed step will increase the stability. However I cannot find it in the BIOS (is it called EIST).... Can anyone help? I have Asus Maximus VII Hero. Also I have managed to get my I7 to 5.250 Ghz (I changed ratio and Strap) on 1.35V, however it did not pass the Windows 8 logo :/, can anyone tell me what the CPU strap is in detail and should it be the same as BCLK? Big thanks to anyone that tries to answer those questions.

I don't think you should start with 5.25 GHz. First learn how to oc something, because increasing the vcore and the BCLK multiplier is not enought. It can easily couse yours hardware death. Before you try those high freqencies read some OC forum, and then make some try. Try different settings in BIOS (you should learn bios first).
And last but not least i would not try to reach 5.25 GHz on aircooling with i7-4770K...
You need to start from the basics dude - smashing in settings when you have no idea what they are will not work.

I have already OC I7 to 4.4 Ghz at 3.5V, I did by increasing the Ratio to 44 (I know my CPU isn't best, we talekd about this in here: http://forum.overclock3d.net/showthread.php?t=65959 ). I have also OC my old core 2 duo E8200 (long ish time ago) from 2.6Ghz to 4Ghz (for the sake of OC) however I hva lowerd it to 3.6Ghz as it was running too hot> Therefore I have some experience and I know the basics.

That's a lotta volts. Typo?

Yes I did mean 1.35V not 3.5V LOL
is it even possible to set CPU at that high voltage?

You really need to read an overclocking guide, the answer to your question will be in there somewhere along with a lot of other important basic stuff.
People are reluctant to answer as you could seriously damage your PC without knowing the basics.

here is the very basics.
please read a reall guide.
start off at stock clock with a minus offset and see how little power you can run stock clocks at. run some tests to make sure its stable.
then go try a faster speed (same voltage) and see if it boots. then do that again. and when it wont boot increase the offset voltage.
keep doing that untill you have the higest clock speeds you can get at a max of 1.35v.
check cpu-z to see what the vcd is and what your providing.
try to use medium v droop or "power saving" vdroop settings if possible in bios.
enable ppl and boot again.
check with aida 64 what your v core is (compared to what you set it at) and use turbo core ofset to increase it if its lower than you need it to be.
check the wattage stated to be used in aida when the cpu is under full load (ibt maximum) and set your bios to not throttle at that value or lower.
keep eye on temps.
you may find that even if you can get the temps down low enough the voltages needed will be to high.

follow the link to the guide Tom referred you to and follow it step by step. Then come back and ask the questions that you want answered. Until then nobody is going to be able to help you.
in your bios enter advanced and then look for cpu power management, open up that menu tree and you should see it. For what its worth I noticed no difference with speedstep disabled vs enable.

do you all disable speed step instead of using offsets?
I prefer using offsets and turbo mode offsets to get my over clocks.
that way i can keep my idle speeds (and idle voltages), and then when turbo mode is Kicked in the offsets handle the differences for me. may take a little bit of fine tuning compared to setting a single voltage. but it does give the best of both worlds.
im using an intel board so its probably different but i assume it should be near enough the same across the board.
you just change your main off set (lower it if possible so your stable at stock)
start over clocking your cores
tell it to use max v droop (power saving) "that stops the board pumping in stupid voltages when turbo kicks in"
sometimes its better to use the med v droop setting. (you can use a lower offset. or rather the lowest number you can enter for turbo mode offset will actually be enough)
then you go and run IBT and check with aida 64 or cpu id what your voltages are and if its not quite stable and you can give it more power you go back in and then change your turbo mode offset.
and thats it really.
i personally think its a better method for overclocking. (24/7) clocks.
can get my i5 2500k to 4.8 stable on all 4 cores like that and still have it idle at 0.9v
but maybe the newer cpu's are different i guess. (seems a lot less involved than it used to be though)

To be honest there no noticeable benefit to disabling EIST (speedstep) on everyday overclocks with a 4770K, in fact there hasn't been much advantage doing it since Haswell came out.
Please be aware guys that there are significant differences between Sandy/Ivy and Haswell regarding the overclocking process which are due to the voltage regulator being integrated into the die.
As shambles points out there are advantages to using speedstep and offset voltages on Sandy/Ivy which allow the CPU to 'rest' when not at load and the drop the voltage which can save a bit of energy and wear on the components. Although it is not as much as people think since the motherboard will automatically reduce the amps supplied anyway. It's not volts that kill, it's Watts (Volts x Amps = Watts).
Anyway, regarding OCing a Haswell or Haswell refresh chip certain things have changed because of the iVR. Certain settings on the motherboard now has no effect on everyday OCs.
LLC/vdroop will now make no difference so leave it at default.
You have the option of manual, offset or adaptive voltages. I'd suggest that you leave it on manual with the energy states on default. This will result on the lowest volts and watts under load because of stability but there is no loss of energy saving since the iVR will automatically reduce voltage when not under load to under 0.001V anyway. Kinda makes offset and adaptive redundant in my opinion.
Adaptive voltage is a really nice idea but if you do try it then be careful of which testing programs you use since not all have been updated with the correct voltage map and some like Prime95 will significantly overvolt your CPU in an adaptive mode.
