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)

100MHz ~ 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 133MHz. 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 module, 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.
