Can't POST with any OC settings

So first off sorry if you're tired of seeing posts like this. I tried googling, and searching the forums, but all I can find are people that couldn't figure out to clear CMOS, or had answers specific to their system.

Can someone help me figure out what I'm doing wrong? I've tried dozens of different set-ups but can't seem to get any of them to even POST. The computer will start up, then restart after a few moments only to try and fail again. After failing, I clear the CMOS and try again with different settings, but nothing seems to work. I must be missing something crucial, but this is my first time trying to OC and I'm a little lost.

System:
CPU: Intel i7 - 6700k
Cooling: Liquid cooling setup
MOBO: Asus Z170-P D3
GPU: Onboard intel graphics (Waiting for GTX 1080)
RAM: Corsair DDR3 - 1600
PSU: Corsair AX1200 (Overkill from a former, more energy intensive, system)


These are the OC settings I started with:

The only settings I changed manually was to set XMP, then sync all cores, then the core ratio limit, and finally the voltage. Everything else changed automatically.


From there I raised the voltage by 0.01 volts with every attempt, until I reached 1.39 volts. At this point I brought down the CPU to 4.4Ghz and started over again at 1.325 volts and worked my way up, then 4.3, 4.2, etc. However I was never able to even boot.

Do I just have bad processor for overclocking? Or am I missing something right in front of my face? Any help is appreciated.
 
Solution
1. Ensure your UEFI is the current version
2. Do not change voltages right away.
3. Do one thing at a time then save.
4. Set your memory to its rated speed and voltage then save and reenter UEFI.
5. Start CPU overclocking start small 1 or .5 e.g. "40.5" or 41. (You should be able to get a few hundred MHZ without increasing VCore.) (I do not think .5 works anymore)
6. After each save boot into windows not just booting into UEFI (loading windows is a much bigger load than loading into the UEFI.) you can get much larger UEFI overclocks thatn windows overclocks because the UEFI is basically no CPU load.
7. Continue increasing multiplier, Once windows starts crashing during boot increase voltage in small increments for stability.

8. You then you have to start going slower (multiplier increase wise) and integrate system stress testing.

Thank you. I tried from the bottom up like you said and it looks like starting at 1.325 volts was just way too much. I'm at 4.2Ghz right now without adjusting the voltage from default and stress testing is going well.
