The same thing happened to me. It took some patience but I feel I have a very nice 3.6 GHz overclock. EZ OC sets the BCLK too high. Start small. I'm using 153 instead of 133. Leave turbo on and V-Droop off. Everything else is pretty much on auto including CPU voltage. See how that goes. If you want I may be able to send you my OC DNA file.
