This board doesn't have LLC (Load-line-calibration) which was very surprising since it isn't a budget board and it was marketed for gamers and overclockers. There are other settings in the Bios dealing with voltage/delivery to the CPU that I do not fully understand and won't touch until I have, at the very least, a basic understanding of their function. I'm already heading towards the voltage limits for this chip (1.450v) and I haven't even got 4.3ghz OC stable! Ideally I'd like to get a lower Vcore at idle and find some way to battle voltage droop during load. The offset brings the Vcore up to 1.368v (though at idle the system Vcore in CPUID is 1.384, but I believe the values are slightly different on how the motherboard steps up each offset I set). The Ring is at 3900GHz, FCLK is at 1000GHz.

I've set an Override Offset of 0.065mv to battle the voltage droop at load. Right now I'm at a Vcore of 1.300v in the Bios. I've had no luck with Intel's Extreme Tuning Utility (just for stress testing, not overclocking with it) and my memory passed four hours of the UEFI MemeTest86 without any errors. I pass AIDA64's stability test without a problem, run a Cinebench CPU benchmark no problem, etc. The best I could do with Intel Burn Test was to pass the standard test, if I tried the next setting up the program would either shut down with a warning message or the computer would freeze up. I ran Prime95 on Blend and after two runs one of my cores stops working. At first I tried the recommend Vcore of 1.250v (at optimized default in the Bios as a starting point) with XMP disabled (just in case) and all power saving features turned off. I haven't been so luck yet and if I don't figure things out by tomorrow I will not be able to replace either the motherboard or the processor (if the fault lies with either one). 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 of 1.250v). I know all overclocks are not the same and I understand that results may very depending on differences in hardware/cooling, etc. I've been having a damned difficult time trying to get a stable overclock with this motherboard (MSI Z170A Gaming M5) and the Intel Skylake 6600K.
