Specs:
Intel 4770K@ 4.12 stable (crap malay batch) @ 1.235 vcore
Corsair h80i w/ 2 deltas in push-pull
Maximus IV gene (base)
2x8 Kingston HyperX Beast 2133 11-11-11-32, 1.65v @ 1866 8-9-8-28-1

I really want to get this chip to 4.2-4.3. I feel that is the best pay off for stability and performance for gaming. I feel like it should be possible with this rig, even though I have a crap chip.

I will give my current voltages and temps.
41x100.3, Cache x39. 1.235 vcore, 1.175 sa, 1.65 dram, the rest is set to auto. Overvoltage off.
Most voltage profiling set to extreme. Under full load my voltage doesn't pass 1.255. When attempting to overclock I set my memory to 1600 9-9-9-28, and set BLCK to 100. Temps are 40-42 @ idle, and 55-57 with intense gaming.

I don't benchmark, I feel like it is useless. Just because I am stable on IBT or Prime95 does not mean I will be stable while gaming.
No matter what I try, no matter how many volts I put into it, it becomes unstable at 4150+ mhz. I have tons of experience overclocking, but there are just too many damn settings to tweak and test on this board to find stability.

Just to get it out of the way, I have read ALL the guides, overclocked a 940, 920, 3570K, and others in recent history with impressive success. This Haswell is a tough cookie.

Please help!
