UEFI

For enthusiasts, the options available within the BIOS/UEFI can turn a good board into a great one. The ability to manipulate frequencies, voltages, and fan control settings vary depending on the hardware and the amount of trust placed in the users' hands by the manufacturer.

As the multiplier cannot be changed on H67 boards, and the CPU frequency can only be increased by a few MHz without compromising the other system buses, most of the voltage/frequency options in the UEFI will go unused. There are plenty of memory options which might have been useful if the board supported desktop memory. It's rather difficult to find high speed DDR3 SO-DIMMs.

The Q-Fan manual settings are fairly standard for an Asus board. Full control is allowed for the CPU fan while the Chassis fan won't go lower than 60%. In addition, the Chassis fan begins to ramp up at 40°C and this cannot be changed as the setting is locked out.
