The Maximus II Extreme is intended to support extreme overclocking, so it includes excessively wide voltage ranges and every possible Intel memory multiplier.
The Extreme Tweaker menu is found first in Maximus II Formula BIOS, and starts with the “CPU Level Up” setting which can approximate the speed of a faster processor by automatically increasing bus speeds to match the desired final speed. Our Core 2 Duo is already the fastest Conroe however, so the only setting found here is “Crazy”. Ai Overclock Tuner will increase and decrease FSB clock automatically in response to system load, but experienced overclockers will find the highest performance through a wide range of manual settings.
Scroll past the full set of memory timings to reveal voltage controls.
The bottom of the Extreme Tweaker menu provides all the needed reference voltage controls to squeeze out the last possible bit of performance.
Final settings can be stored to a BIOS profile or saved to a USB drive. This prevents settings from being lost if BIOS needs to be cleared following a boot failure.
