your cpu voltage is too low. 1.2v while pushing 4.05ghz will most likely lead to unstability of your OC. However if you are able to get it to load and 15min stress test with that, you have a good cpu. But my bet is if you run stress test for more than an hour it will end up failing because the low cpu voltage.
I'd like stay under 1.30V, because I think it's going to get a little bit too hot, not sure, but it's possible.
Just increased the CPU voltage to 1.25V and it's +1.23V after drop. I'm going to test my system really soon, 1-2 hours running orthos (RAM and CPU testing). Then I'm going to play a lot and test everything that could crash it, and if not, it's stable and maybe trying to get higher.
