Same 3418C011 batch here,
CB15 4500MHz at 1.17Vcore, so pretty great daily CPU, on air goes up to 4700MHz 1.33Vcore... 4800MHz doesn't post at all, not even with 1.5Vcore lol...
CB15 5800MHz at 1.7Vcore at -80°C
hard walls at 5960MHz, temps, volts doesn't matter, that's it...
So how do we bin these buggers, just see which CPU goes up over +4.9 into windows... the ES does 4.9 1.36 and goes up to 6.1Ghz and then also walls hard...
