ASRock uses identical menus both for both its Fatal1ty P67 Professional and P67 Extreme6 motherboards, reserving visible differences only to the background image. The P67 Extreme6 features a more industrial blue-grey background.
ASRock is among the brands that can use programming tricks to make the installed CPU run at its maximum Turbo Boost frequency full-time, which is apparently against Intel's design recommendations, but preferable to anyone accustomed to overclocking previous Intel platforms. That basically means that disabling Turbo Boost and increasing the standard multiplier does just the opposite, forcing Turbo to stay at full throttle using whatever multiplier the overclocker desires.
Separate voltage controls address the CPU core, PLL, VTT, and CSA voltages. We needed to use the 1.344 V core setting along with Level 1 load-line calibration to sustain 1.35 V under full load when overclocked.
ASRock addresses a modest number of memory settings, in addition to the usual four that most tuners set. Slightly annoying is the fact that each menu must be set to Manual before the actual number can be changed in a drop-down menu beneath it.
