BIOS
BIOS options on mATX boards are typically very spartan. The
presence of an IGP and the more limited cooling associated with an mATX platform
makes manufacturers nervous about allowing users to customize
their clock / voltage settings.

The BIOS provides a good amount of functionality without getting
too fancy. All the important options are present: CPU and RAM frequency / voltage,
memory timings, and chipset voltage. It also allows manipulation of the integrated
graphics core and shader frequencies.

Frequency and voltage control options.
|
The BIOS handles frequency in an unusual way —
the effective system front side bus and memory speeds are used rather than
the base frequency. So, unlike most motherboards, the FSB is already quad-pumped
and the RAM frequency doubled. We encountered the same thing on the
Zotac
NF610i-ITX — it seems to be the way nVidia likes to handle clock adjustments,
though it does take some getting used to.

"Hardware Monitor."
|
Fan control settings are available in the "Hardware Monitor"
menu. The board can control the CPU and Chassis fan header with three different
modes: Silent, Optimal, and Performance.
