CPU Clock Ratio (8X)
Enables you to set the CPU clock. The CPU clock ratio times the CPU Host/PCI Clock
should equal the core speed of the installed processor. (For unlock Ratio CPU only.)
Example: CPU Clock Ratio 8
CPU Frequency X200
Installed CPU Clock Speed 1600 MHz
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 Clock (200MHz)
Use the CPU Host Clock to set the frontside bus frequency for the installed processor. You
can key in the number within the range to make a precise and ideal adjustment.
