Trouble OC'ing with MSI M5 + 6600K

Hello,

I've been having a damned hard time trying to get a stable overclock with this motherboard (MSI Z170A Gaming M5) and the Intel Skylake 6600K. I know all overclocks are not the same and I understand that results may vary depending on differences in hardware / cooling, etc. but I though the 6600K was easy to overclock and at relatively low voltages (I often read of people getting to 4.4Ghz at a Vcore or 1.250v). I have not been so luck yet and if I do not figure things out by tomorrow, I will not be able to replace either the motherboard or the processor.

I did not find the right solution from the internet.
