4.5GHz is doable 2-ways: 43x104~105, where it requires around 1.3-1.32V with my P9X79 Pro or 36x125 that needs more and would hover around 1.385-1.39. 4.625 (37x125) would break 1.42V.

Values are what CPUz was reporting under full load (F@H), including offsets etc, and there was variation (not always going down) between BIOS versions.
I was always going for sub 80s oC temps, so I did not push harder as I "only" had my Silver Arrow, and ofc with better cooling better clocks are possible with slightly lower Vcore. Just opted to get a 3930K instead of a loop biggrin.gif

The chip has very consistent temps between cores, 3-4oC top variation from max to lower. My new 3930K has more than 8 (under air @ 4.7).

The CPU was bought Aug 2012.
