BIOS
For enthusiasts, the options available within the BIOS 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.

Like many mini-ITX boards, the H55-ITX's BIOS is severely restricted.
Voltages can be adjusted for the CPU, PCH, RAM, and the integrated GPU, but
the ranges offered are minuscule. Particularly disappointing is a -0.100V undervolt
limit for the CPU. The board has dynamic fan control with adjustable options
as well as a fixed manual speed option.
