I can get to 4.5ghz prime stable on air cooling (venomous-x) with 1.39xx vcore under load. I've gone as high as 1.475 vcore and still can't get into windows at 4.6ghz or above ( I can post at 4.6 ghz and above but windows freezes up during the opening splash screen). I've played with most of the settings such as phase control, LLC, internal PLL overvoltage, VRM frequency, etc, and 45x seems to be the wall for this chip- or at least a wall that 1.475 vcore with extreme LLC won't break (and I'm not willing to push more that that right now). Anyone have a similar experience?

Figures I would get a lemon...who would have thought that 4.5 ghz would be considered a less than stellar OC performance?!?
Too much vcore or maybe (most likely) memory voltage or timings.
