Ok, this is strange.. I have Asus PC Probe II open while priming for a monitor, and my vcore is at 1.300 right now... and now I'm only hitting temps in the mid 70c range...
Try either or both of these for temp monitoring.
Also you are stress testing. So might want to give it a break for a few minutes. 1.3 volts is pretty low for 4ghz though. Did it crash or pass?
