I was getting 90degrees+ when testing with prim95. What's a safe vcore for 4.2ghz?
1.22v would be more than fine, the trouble is that the auto selection increases voltage with load, so it's giving the chip way more juice than it needs and producing those horrible temps you have.
Also - what cooling solution do you have? You shouldn't be doing this with the stock intel cooler.
