CPU Clock Ratio
This setup option will automatically assign by CPU detection.
The option will display "Locked" and read only if the CPU ratio is not changeable.
CPU Host Clock Control
Disabled Disable CPU host clock control. (Default value)
Enabled Enable CPU host clock control.
CPU Host Frequency(Mhz)
This item will be available when CPU Host Clock Control is set to Enabled.
100Mhz ~ 355Mhz Set CPU Host Clock from 100Mhz to 355Mhz.
If you use a 400Mhz FSB processor, please set CPU Host Frequency to 100Mhz.
If you use a 533Mhz FSB processor, please set CPU Host Frequency to 133Mhz.
If you use an 800Mhz FSB processor, please set CPU Host Frequency to 200Mhz.
AGP/PCI/SRC Fixed
Adjust AGP/PCI/SRC clock asynchronous with CPU.
Memory Frequency For
Wrong frequency may make system can't boot, clear CMOS to overcome wrong frequency issue.
for FSB(Front Side Bus) frequency =400Mhz,
2.66 Memory Frequency = Host clock x 2.66.
Auto Set Memory frequency by DRAM SPD data. (Default value)
for FSB(Front Side Bus) frequency=533Mhz,
2.0 Memory Frequency = Host clock x 2.
2.5 Memory Frequency = Host clock x 2.5.
Auto Set Memory frequency by DRAM SPD data. (Default value)
Incorrect using these features may cause your system broken. For power end-user use only.
