CPU Clock Ratio
This field allows you to select the clock ratio. Most CPU clock ratios are fixed in-
side the CPU by the manufacturers that prohibit you to make any changes. In
this case, the setting in this field will make no change to the CPU clock ratio
since it locks and is automatically determined by the CPU.
Auto Detect DIMM/PCI Clk
When “Enabled” is selected, the mainboard will detect the presence of devices on
DIMM and PCI slots. When there is no device present on some of the PCI or
DIMM connectors, the clock on the related DIMM and PCI slot will be disabled to
reduce the Electro-Magnetic Interference (EMI).
Spread Spectrum
When Spread Spectrum is enabled, the EMI radiation on this mainboard will be
reduced.
CPU Clock
You can use this field to adjust the front side system bus clock speed of the CPU.
The clock frequency can be incremented by +/- 1MHz. This allows you to fin-
tune the system performance of your PC.

3.11. Load Fail-Safe Defaults
Load Fail-Safe Defaults
This option loads troubleshooting default values which are permanently stored
on the BIOS ROM Chip. If you made changes to the BIOS settings and your sys-
tem has become unstable, you can change it back to the default settings. If you
have made many changes to the BIOS settings and you are not sure which set-
ting is causing the problem then you should choose this option. This will load the
minimal performance settings and stabilize your system.
