Accidental CPU Overvoltage

I recently purchased an i5 4670k with an ASUS z87-a about a week ago. In my overclock attempt to raise the voltage to 1.18, I hit 1.8 by mistake (stupid me, yes, I know..). Upon restart to implement changes I did receive the overvoltage CPU error in the BIOS load screen and instantly changed my voltage back to safe ranges.

Now, I went back to a very conservative overclock and ran Prime95 - crashed within minutes. I restarted my CMOS and get the same results.

I'm assuming I partially damaged my CPU. Is there a chance that I partially damaged my motherboard? Is there any way to test my compenents individually without trying a different CPU to remove any variables?

Thanks guys.

Yes, and by conservative I mean 4.3 Ghz @ 1.17... which was actually the furthest I've tested it. I say conservative based on the voltage amount. Now when I try at these settings it crashes very quickly.

I should also note that I tried 4.3 @ 1.18 and it also failed. This all happened last night so I haven't had much time to perform many tests and see what I can now get as a stable overclock.

Any thoughts on my situation?

Update: Passed Prime 4.3 @ 1.90v. I guess I'm still understanding how something could be "slightly" damaged or "off" now that it had that quick jolt. It was running 4.3 fine @ 1.70v but I'm just happy it's stable. I never tried 4.4 so who is to say it wouldn't take a couple more clicks just to get that. I'll leave it at 4.3 for a while and be extra careful from now on.

Same thing happend to me with 4690k and z-97 a. Rebooted, the second it showed anything I got bsod, then I reverted the settings. Is their any chance that my CPU will die soon?
