CPU Clock Ratio

This option will not be shown or not be available if you are using a CPU with the locked ratio.

This setup option will automatically assign by CPU detection.

For C-Stepping P4: 8X,10X~24X default: 15X

For Northwood CPU: 12X~24X default: 16X

The option will display "Locked" and read only if the CPU ratio is not changeable.

Auto Detect PCI/DIMM Clk

Disabled Disable auto detect PCI/DIMM Clk.

Enabled Enable auto detect PCI/DIMM Clk. (Default value)

Spread Spectrum

Disabled Disable spread spectrum.

Enabled Enable spread spectrum. (Default value)

CPU Host Clock Control

Note: Please note that if your system is overclocked and cannot restart, please wait 20secs.

for automatic system restart or clear the CMOS setup data and perform a safe restart.

Disabled Disable CPU Host Clock Control. (Default value)

Enabled Enable CPU Host Clock Control.

CPU Clock

Incorrect using it may cause your system broken. For power End-User use only!

100~166 For 100MHz CPU:Set CPU Clock to 100MHz~166MHz.

133~199 For 133MHz CPU:Set CPU Clock to 133MHz~199MHz.

200~250 For 200MHz CPU:Set CPU Clock to 200MHz~250MHz.

DRAM Clock (MHz)

Please set DRAM Clock according to your requirement.

Incorrect using it may cause your system broken. For power End-User use only!

100-DDR200 If you use DDR200 DRAM module, please set "100-DDR200".

133-DDR266 If you use DDR266 DRAM module, please set "133-DDR266".

166-DDR333 If you use DDR333 DRAM module, please set "166-DDR333".

200-DDR400 If you use DDR400 DRAM module, please set "200-DDR400".

By SPD Set Memory frequency by DRAM SPD data. (Default value)

AGP OverVoltage Control

Increase AGP voltage may get stable for Over_Clock. But it may damage to AGP Card when

enable this feature.

Auto Supply voltage as AGP Card reguired. (Default value)

+0.1V Set AGP OverVoltage Control to +0.1V.

+0.2V Set AGP OverVoltage Control to +0.2V.

+0.3V Set AGP OverVoltage Control to +0.3V.

DIMM OverVoltage Control

Increase DRAM voltage may get stable for Over_Clock. But it may damage to DRAM module

when enable this feature.

Auto Supply voltage as DRAM module reguired. (Default value)

+0.1V Set DIMM OverVoltage Control to +0.1V.

+0.2V Set DIMM OverVoltage Control to +0.2V.

+0.3V Set DIMM OverVoltage Control to +0.3V.
