5820K overclocking issues

[Suffokation]

I've recently being overclocking my 5820K, it was originally sitting at 4Ghz at all times. I've pushed it up to 4.7 stable, for around a week. I'd start my computer and my bios would tell me my overclock is unstable and it would turn off. I'd restart and enter the bios, change the multiplier to 4.6 and then reboot, and it booted just fine. I'd then restart and change it to 4.7Ghz, it would work for a week and then become unstable again. I'd put it back to 4.6Ghz, run it again and it would be fine. But, around a week ago it said that the 4.6GHz was unstable. I have turned my ram overclock on and off and there is no difference. They are running in XMP. This is really odd, can someone give me a hand with this?

What are you voltage settings? CPU, Cache (also called ring), VCCIN, System Agent, etc.

CPU voltage is 1.4, and everything else is at stock clocks.

O_o

Pushin it a little hard for 24/7 use. 4.7 is likely not going to be stable, even at that voltage. To get my 5960X stable I had to up the System Agent voltage to 1.15v, VCCIN (input voltage) to 1.88v, and VCCIO CPU to I believe 1.1v, I'll grab some BIOS screens when I get back from dinner. Just be aware that 4.7 on any Haswell-E is hard to get 24/7 stable w/out going a little nuts with all the voltage settings. Mine won't even get past POST w/1.55v @46 <_<

Ahhh. Well thank you.

I will take it down to 45 and see how it goes.
