Gigabyte 8I845GE-RZC [33/40] Frequency voltage control

- 33 - BIOS Setup

English

Frequency/Voltage Control

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.

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

If you use a Pentium 4 CPU with FSB 533MHz, please set "CPU Clock" to 133MHz. For a P4 CPU

with FSB 400MHz, 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 modes 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 Memory 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 Memory frequency by DRAM SPD data. (Default value)
