Can't seem to get CPU overclock stable...

I can't seem to get my CPU stable. The BIOS presets are not working, and nothing I do manually seems to be able to get it stable either. Stock, everything is rock solid. But if I even get to 4Ghz (which should be possible with even the worst chips) I have just hard locks. No BSOD, no crashing, just a hard lock. Holding down the power button is the only way to get the computer back. The reset button doesn't even work. Any ideas what the problem might be? I've run intel's stability testing program for 8 hours on my memory, and it came back as stable at stock as well, and I haven't tried to even overclock that.

 


Specs are in sig, but it's an i7 5930k and an asrock x99x killer

I'd try doing a CMOS reset.

I've reset the UEFI a few times, but I haven't actually pulled the cmos battery. I'm not sure if that would make a difference or not. I did set it to hold the max turbo frequency on all cores, so it'll go up to 3.7Ghz now and I've had no issues with that. It's just frustrating as I know the CPU should be capable of more, but I can't seem to get it to work. I actually bought the asrock because the gigabyte (and to a lesser extent) asus boards that I was also considering got much worse reviews for stability and weird issues. I really hope that it's not a problem with the motherboard, but anything is possible I suppose.
