50
CPU Ratio
Use this item to select a multiplier for the system frontside bus (FSB) fre-
quency. 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/DDR Voltage Regulator (Default)
If you are manually configuring the CPU/DDR clock, use this item to set the
CPU/DDR voltage for more stability.
Load Fail-Safe Defaults
This option opens a dialog box that lets you install fail-safe defaults for all ap-
propriate items in the Setup Utility:
Press <Y> and then <Enter> to install the defaults. Press <N> and then <En-
ter> 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 cor-
rectly, 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 spe-
cific 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 opti-
mized 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>.
