CPU Lock Free [Auto]

Allows you to adjust the CPU multiplier to 14x. Setting this item to [Auto] allows the motherboard to automatically reduce the CPU multiplier value for more flexibility when increasing the external FSB. This item appears only if you installed a CPU with the CPU Lock Free feature.

Configuration options: [Auto] [Disabled] [Enabled]

The following items appears only when the AI Overclock Tuner item is set to Manual.

CPU External Frequency [XXX] (value is auto-detected)

Indicates the frequency sent by the clock generator to the system bus and PCI bus. The bus frequency (external frequency) multiplied by the bus multiple equals the CPU speed. The value of this item is auto-detected by BIOS. The values range from 100 to 400. Refer to the following table for the correct Front Side Bus and CPU External Frequency settings. Use the <+> and <-> keys to adjust the value.

DRAM Frequency [Auto]

Sets the DDR operating frequency.

Configuration options: [266 Mhz] [320 Mhz] [400 Mhz] [Auto]

•Refer to the DDR documentation before setting the memory

frequency. Setting a very high memory voltage may damage the memory module(s)!

•Selecting a DRAM frequency that is not supported by your DIMM module may cause the system to become unstable! If this happens, revert to the default setting.

AGP/PCI Frequency (MHz) [Auto]

Sets the AGP/PCI operating frequency. Configuration options: [Auto] [66.66/33.33] [72.73/36.36] [80.00/40.00]

CPU VCore Voltage [Auto]

Allows selection of the CPU VCore voltage. The configuration options vary depending on the CPU installed. Setting to Auto allows the BIOS to detect the VCore voltage of the CPU installed.

Refer to the CPU documentation before setting the CPU VCore voltage. A very high Vcore voltage can severely damage the CPU!

DDR Reference Voltage [Auto]

Sets the DDR reference voltage. Configuration options: [2.85V] [2.75V] [2.65V] [2.55V] [Auto]
