DFI NF4 SLI Infinity
Motherboard
The Bios

After a successful install and power up we need to
configure the system using the all to familiar Phoenix Award BIOS CMOS Setup
Utility. With this aged (non mouse enabled) interface, most enthusiasts can have
their system setup and fully tweaked in under 60 seconds. While all of the
sub-menu items have their purpose and importance in getting a system properly
configured, the Genie BIOS setting is undoubtedly where most overclockers
will be spending their time.

DFI has
included all of the major players for Overclocking success in the Genie BIOS
setting menu. In addition to the CPU Frequency and Hammer FID control (why don't
they just call it a multiplier?), we have the complete DRAM Configuration page,
and total control over all the important voltages; DDR, CPU, and chipset. The
printed manual which accompanies the motherboard offers next to no help getting
this area of the system up and running. However, DFI has included electronic
versions in PDF format which cover the motherboard in much greater detail.

While
overclocking features may have become an unwritten standard, the fact remains
that overclocking is still for advanced users. Anyone considering overclocking
their rig needs to understand that the potential to damage or even destroy your
hardware is a possibility. DFI has included this warning statement before the
description of each voltage setting in the Genie BIOS setting menu. The voltage
ranges available should be more than adequate for a successful overclocking
endeavor. Extreme overclockers may be a little disappointed in the CPU voltages
available, but this board isn't really intended for extreme overclocking.
Still, a very respectable overclock should be easily attained with the settings available
here.
