Spec is
2500k
2x4gb corsair vengeance
4870
essence stx
antec 650w psu
z67xp-ud3p (i'm fairly sure its rev 1.0)
6 case fans and nh-d14 cooling it all
Yesterday evening I overclocked my CPU to 4.5ghz by following this guide

By selecting 1.33 as the vcore i had a stable overclockng according to Intel Burn. What i noticed though, in cpu-z (i think it was this, maybe it was hwmonitor) it said my vcore was around 1.63 volts (compared to 1.33v in the bios) I was a bit worried about that since it seemed a tad high.
So instead of lowering it by .05 volts each time i knocked it down to 1.15 in bios, assuming cpuz would still record a higher than 1.33v figure. Ran intel burn on high again and it stayed stable.
I left the PC for a couple of hours idling and when I came back, it was continuously starting up and restarting after just 1 second.
I left the computer unplugged for 8 hours and tried it this morning but the problem remains.
Any ideas?
Thanks.
