CPU Host Frequency

This option is available only when FSB-Memory Clock Mode is set to Linked or Unlinked. The first frequency value is adjustable and the second is the standard operating frequency of your CPU. 100 ~ 650 Set CPU Host Frequency from 100 MHz to 650 MHz.

The actual range depends on the CPU you install.

If you use a 533 MHz FSB processor, please set CPU Host Frequency to 133 MHz. If you use an 800 MHz FSB processor, please set CPU Host Frequency to 200 MHz. If you use a 1066 MHz FSB processor, please set CPU Host Frequency to 266 MHz. If you use a 1333 MHz FSB processor, please set CPU Host Frequency to 333 MHz.

Actual CPU Clock (Mhz)

The values depend on CPU Host Frequency setting.

Memory Frequency (Mhz)

This option is available only when FSB-Memory Clock Mode is set to Unlinked. The first frequency value is adjustable and the second is the standard operating frequency of your memory.

400 ~ 1400 Set Memory Frequency from 400 MHz to 1400 MHz.

Actual Memory Clock (Mhz)

The values depend on Memory Frequency setting.

PCIe Bus, Slot 1, MHz

100 ~ 150

Set the clock for the onboard PCIe x16 slots from 100 MHz to 150 MHz.

CPU Clock Ratio (Note)

This setup option will automatically assign by CPU detection.

The option will display "Locked" and read only if the CPU ratio is not changeable.

System Voltage Control

This item allows the users to decide whether to configure system voltage settings by their requirements.

Auto Manual

DDR2 Voltage Control

Please note that by overclocking your system through the increase of the DDR2 voltage, damage to the memory may occur.

NormalSupply the DDR2 voltage as required. (Default value) +0.025V~+0.775V Increase the DDR2 voltage by 0.025V to 0.775V.
