Using BIOS
Frequency/Voltage Control
This item enables 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.

CPU Clock Ratio (0X)
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 X100
Installed CPU Clock Speed 800 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.
Clock Control By (Auto)
You can select auto or manual to set the system-operating clock by type and speed of your
CPU and DDR.
• Async AGP/PCI/SATA Clk :This item allows you to select the fixed clock to
generate the output to AGP/PCI/SATA frequency.
• CPU Frequency: This item allows you to set the CPU frequency.
• CPU: DRAM Frequency Ratio: This item controls the ratio of the CPU FSB
clock and DRAM Frequency to enable the CPU and DRAM to run at different
frequency combination.
DRAM Frequency (133MHz)
This item displays the memory (DRAM) frequency. This is a display-only item.
