PCI Health Status Option
On mainboards which support hardware monitoring, this item
lets you monitor the parameters for critical voltages, critical
temperatures, and fan speeds.
If this option is active on your system, we recommend that you
accept the default values.
Frequency Control Option
This item allows you to set the clock speed and system bus for
your system. The clock speed and system bus are determined
by the kind of processor you have installed in your system.
Auto Detect DIMM/PCI Clk Default: Disabled
When this item is enabled, BIOS will disabled the clock signal of
free DIMM and PCI slots.
CPU Internal Core Speed Default: Auto
Use this item to automatically set up the mainboard for the kind
of processor that you have installed. Set this item to the rated
internal clock speed of the installed processor. If you set this to
Manual, two new items appear:
CPU/DIMM/PCI Clock and CPU
Clock Ratio.
Spread Spectrum Default: Disabled
If you enable spread spectrum, it can significantly reduce the
EMI (Electro-Magnetic Interference) generated by the system.
CPU/DIMM/PCI Clock CPU Clock ratio
These items appear if you have set the CPU Internal Core
Speed to Manual. Use the CPU/DIMM/PCI Clock to set the
system bus frequency for the installed processor (usually 133
MHz,100 MHz or 66 MHz). Then use
CPU Clock Ratio to set a
multiple. The multiple times the system bus must equal the core
speed of the installed processor e.g.
3.5 (multiple) x 100 MHz
(system bus) = 350 MHz (installed processor clock speed) .
