BIOS Setup > Frequency/Voltage Control > CPU Clock Setting
This motherboard is CPU jumper-less design, you can set CPU frequency through the BIOS setup, and no jumpers or switches are needed.
Core Frequency = CPU
FSB
Clock * CPU Ratio
PCI Clock = CPU FSB Clock / Clock Ratio
AGP
Clock = PCI Clock x 2
CPU Ratio
From 5.0x to 22.0x
CPU FSB (By manual Adjustment)
FSB=100~255 by 1MHz stepping adjustment technology
Warning: SIS 748 Chipset supports maximum 400MHz system bus and
66MHz AGP clock; higher clock setting may cause serious system damage.
Please be informed that SiS748 A0 Chipset does not support
