I just got back from MicroCenter, picked up my 3rd 3770K and this one could be good. Booted into Windows at 5Ghz 1.4v LLC High on MVG. I bought an L223B781 a few days ago and couldnt even boot into Windows above 47X and my first chip couldnt boot into windows above 48X not matter what voltage so this is my best chip so far.

Have to run out but will start testing when I get back and report back.
