CPU External Frequency (MHz) [XXX]
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 and is not manually configurable. 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 FSB.

DRAM Frequency [Auto]
Allows you to set the DDR operating frequency. Configuration options:
[266 MHz] [333 MHz] [400 MHz] [500 MHz] [533 MHz] [Auto]
AGP/PCI Frequency (MHz) [Auto]
Allows you to adjust to a higher AGP/PCI frequency for better system
performance and overclocking capability. Configuration options: [Auto]
[66.66/33.33] [72.73/36.36] [80.00/40.00]
Selecting a very high AGP/PCI frequency may cause the system to
become unstable! If this happens, revert to the default setting.
CPU VCore Voltage [Auto]
Allows you to select a specific CPU VCore voltage. Configuration options:
[Auto] [1.9500V] [1.9250V] [1.9000V] [1.8750V] [1.8500V] [1.8250V]
