Getting Whea_uncorrectable_error help

[Redhawkcrazed]

Hi, I've recently built a new pc, and I'm occasionally getting a Whea_uncorrectable_error. It seems to happen most when I'm using the Asus AI Suite III to overclock my CPU, (it always does this) Could this be an CPU failure?(I hope not its a brand new cpu.) My system specs are 

Intel i5-4670k 

Noctua NH-U12P cooler

Asus z87 Expert motheboard. 

Corsair Dominator Platium 8gb ram

1 TB HDD

1.5 TB used HDD

NZXT Phantom Classic case

Thermaltake 850W PSU

(Right now I'm running off of the integrated graphics on the cpu, though i plan to add a r9 290 once it arrives.)

My os is Windows 8.1, and if my comp crashes again I'll post the error info as I don't have it currently.

This is a modified repost of my original post, which I accidentally posted under the CPU forums.

You're pushing your overclock too far. Back it off.

I've gone into the bios and reset it back to default settings. The current overclock is (according to AI Suite III) is 40 mhz.. I should also point out that there;s an inconsistency from what cpu-z says the base clock is and what AI suite III says the base clock is. AI suite says 80, cpu-z says 100.2
