The following seven items are adjusted by typing the desired values using the
numeric keypad and press the <Enter> key. You can also use the <+> and <->
keys to adjust the value. To restore the default setting, type [auto] using the
keyboard and press the <Enter> key.
CPU Voltage [Auto]
Allows you to select the CPU voltage. The text color in the configuration field
corresponds to the onboard CPU LED color, both of which indicate voltage
condition. When you set the CPU LED Selection item to [Vcore], the onboard CPU
LED displays CPU voltage condition. Refer to page 2-1 for CPU LED definition.
The values range from 0.85000V to 2.50000V with a 0.00625V interval.
Refer to the CPU documentation before setting the CPU voltage. Setting a
high voltage may damage the CPU permanently, and setting a low voltage may
make the system unstable.
CPU PLL Voltage [Auto]
Allows you to select the CPU PLL voltage. The text color in the configuration
field corresponds to the onboard CPU LED color, both of which indicate voltage
condition. When you set the CPU LED Selection item to [CPU PLL], the onboard
CPU LED displays CPU PLL voltage condition. Refer to page 2-1 for CPU LED
definition. The values range from 1.50V to 2.78V with a 0.02V interval.
FSB Termination Voltage [Auto]
Allows you to select the Front Side Bus Termination voltage. The text color in
the configuration field corresponds to the onboard NB LED color, both of which
indicate voltage condition. When you set the NB LED Selection item to [VTT], the
onboard northbridge LED displays FSB Termination voltage condition. Refer to
page 2-2 for northbridge LED definition. The values range from 1.10V to 2.00V with
a 0.01325V interval.
Setting a high FSB termination voltage may damage the chipset and CPU.
DRAM Voltage [Auto]
Allows you to select the DRAM voltage. The text color in the configuration field
corresponds to the onboard memory LED color, both of which indicate voltage
condition. Refer to page 2-2 for memory LED definition. The values range from
1.80V to 3.08V with a 0.02V interval.
North Bridge Voltage [Auto]
Allows you to select the northbridge voltage. The text color in the configuration field
indicates voltage condition. When you set the NB LED Selection item to [NB], the
onboard northbridge LED displays northbridge voltage condition. Refer to page
2-2 for northbridge LED definition. The values range from 1.10V to 2.00V with a
0.01325V interval.
