Incorrect using these features may cause your system broken. For power users only.
CPU Clock Ratio
This setup option will be automatically assigned by CPU detection.
The option will display "Locked" and read only if the CPU ratio is not changeable.
CPU Host Clock Control
Please note that if your system is overclocked and cannot restart, please wait 20 secs.
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 Host Frequency (Mhz)
This item will be available when "CPU Host Clock Control" is set to Enabled.
100M Hz ~ 355MHz
If you use a Pentium 4 CPU with FSB 533M Hz, please set "CPU Clock" to 133MHz. For a P4 CPU
with FSB 400M Hz, please set it to 100MHz.
Inappropriate using it may cause your system corrupted. For power End-User use only!
Fixed PCI/AGP Frequency
You can choose those m odes to adjust PCI/AGP frequency. (Select PCI/AGP frequency
asynchronous with CPU frequency).
Host/DRAM Clock ratio
For FSB (Front Side Bus) frequency=400MHz,
2.0 Memory Frequency = Host clock X 2.0.
2.66 Memory Frequency = Host clock X 2.66.
Auto Set M em ory frequency by DRAM SPD data. (Default value)
For FSB (Front Side Bus) frequency=533MHz,
2.0 Memory Frequency = Host clock X 2.0.
2.5 Memory Frequency = Host clock X 2.5.
Auto Set M em ory frequency by DRAM SPD data. (Default value)
