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. The values range
from 100 to 400, use the plus (+) or minus (-) key to adjust the frequency. Refer to
the following table for the correct Front Side Bus and CPU External Frequency
settings.
DRAM Frequency [Auto]
Allows you to set the DDR operating frequency. Configuration options: [266 MHz]
[333 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] ... [1.5000V]
Refer to the CPU documentation before setting the CPU VCore voltage. A very
high Vcore voltage may severely damage the CPU!
