CPU Ratio
Use this item to select a multiplier for the system frontside bus (FSB)
frequency. The value of the multiplier must be set so that:
Multiplier x Frontside Bus Frequency = CPU Clock Speed
For example, if you have a processor that is rated to run at 450 MHz and the
system is running a frontside bus frequency of 100 MHz, you should select a
multiplier of 4.5 so that:
4.5 (Multiplier) x 100 MHz (frontside bus) = 450 MHz (CPU clock)
Auto Detect DIMM/PCI Clk (Enabled)
When this item is enabled, BIOS will disable the clock signal of free DIMM and
PCI slots.
Spread Spectrum (Enabled)
If you enable spread spectrum, it can significantly reduce the EMI (Electro-
Magnetic Interference) generated by the system.
CPU Host/AGP/PCI Clock (Default)
Use the CPU Host Clock to set the frontside bus frequency for the installed
processor (usually 133 MHz, 100 MHz or 66 MHz).
CPU Voltage Regulator (Default)
If you are manually configuring the CPU clock, use this item to set the CPU
voltage for more stability.
Load Fail-Safe Defaults
This option opens a dialog box that lets you install fail-safe defaults for all
appropriate items in the Setup Utility:
Press <Y> and then <Enter> to install the defaults. Press <N> and then
<Enter> to not install the defaults. The fail-safe defaults place no great
demands on the system and are generally stable. If your system is not
functioning correctly, try installing the fail-safe defaults as a first step in getting
your system working properly again. If you only want to install fail-safe
defaults for a specific option, select and display that option, and then press
<F6>.
Load Optimized Defaults
This option opens a dialog box that lets you install optimized defaults for all
appropriate items in the Setup Utility. Press <Y> and then <Enter> to install
the defaults. Press <N> and then <Enter> to not install the defaults. The
optimized defaults place demands on the system that may be greater than the
performance level of the components, such as the CPU and the memory. You
can cause fatal errors or instability if you install the optimized defaults when
your hardware does not support them. If you only want to install setup defaults
for a specific option, select and display that option, and then press <F7>.
