Help Overclocking a i7 6700k on an Z170 Pro Gaming mobo

[wallenfox]

I'm having a heck of a time trying to get a good overclock out of my skylake and I figured I'd ask for some advice from the community.

My system:
--------
i7 6700k
Z170 Asus Pro Gaming (Bios 803)
Corsair Vengeance LPX DDR4-3200 (16-18-18-36 / 1.35v)
Single Gigabyte Windforce Nvidia 980
Cooler Master Hyper 212 EVO
x4 200mm case fans (2 intake, 2 output)
Termaltake 750w PS

Using Real Bench, Real Temp, CPU-Z and HWiNfo64 to watch things.

Nothing amazing hardware wise but seems like I should be able to get a better overclock out of it than what I'm getting.

I'm able to get 4600 @ 46x100/1.354v (adaptive and manual) with temps hitting 82-84C using a Real Bench 15 min stress test. I also have the memory running at 3200 rather than the 2133 defaults. Fans are all capped out over 75C

I can't get anything stable past 4600 no matter what I do. I've tried the following settings which all result in crashes or just not booting:

4600 @ 46x100/1.30v (crashes)
4600 @ 46x100/1.33v (crashes)
4600 @ 23x200/1.35v (won't even boot)
4700 @ 47x100/1.42v (crashes as soon as I start test)

I feel like this is a) running to hot and b) requires to much voltage. Am I off base or is this similar to others experiences? Am I expecting to much for this set of hardware?

Thanks.

In my opinion you are expecting to much for air cooling, it all comes down to the CPU, some are better than others, there is no getting around that
4.6 GHZ seems to be the sweet spot for 6700K's above that some start taking to much voltage, but again it's the luck of the draw
Mine does 4.8 stably at 1.35 volts adaptive which peaks at about 1.376 using a Corsair H110i GT but I run a daily overclock of 4.6 at 1.3 volts adaptive which peaks at about 1.32 volts

Thanks for the reply - good info.
