CPU Clock Ratio

This setup option will automatically assign by CPU detection. For Willamette CPU:

8X~23X default: 14X 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.

Linear Frequency Control

Disabled	Disable this function . (Default value)
Enabled	Enable this function.

CPU Clock (MHz)

100M Hz ~ 355MHz Set CPU Host Clock from 100MHz to 355MHz.

If you use FSB400 Pentium 4 processor, please set "CPU Clock" to 100MHz.If you use FSB533 Pentium 4 processor, please set "CPU Clock" to 133M Hz. If you use FSB800 Pentium 4 processor, please set "CPU Clock" to 200MHz.

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

DRAM Clock (MHz)

Please set DRAM Clock according to your requirement.

If you use DDR266 DRAM m odule, please set "DRAM Clock(MHz)" to Auto or 266 . If you use DDR333 DRAM module, please set "DRAM Clock(MHz)" to Auto or 333.

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

AGP/PCI Clock Control

AUTO	Set AGP/PCI Clock Control to AUTO. (Default value)
Manual	Set AGP/PCI Clock Control to Manual.
