Spread Spectrum
This field should always set to be "Disabled" for better system stability.
CPU Host Frequency
This allows you to set the front side bus frequency for the installed processor.
[Auto]
The motherboard detects the jumper setup and sets the CPU host frequency
automatically.
[Manual]
This allows user to set CPU host frequency manually. However, this is not
recommended unless user thoroughly knows the feature. Wrong setup may
cause problems during operation.
CPU Ratio Selection
CPU Ratio is the multiple that times the frontside bus frequency will equal
the core speed of the installed processor. Whether the option is open or locked
is determined by the installed processor.
SDRAM Frequency
If [Auto] is selected, the motherboard will detect the memory module(s) inserted
and assigns appropriate frequency automatically.
AGP Mode
The default is 4X. You may also choose 1X or 2X for older version of
VGA cards.
AGP Aperture Size
It refers to a section of the PCI memory address range used for graphics
memory. We recommend that you leave this field at the default value unless
your AGP card requires other sizes.
