Over Voltage
The Over Voltage function allows you to manually adjust to a higher
core voltage that is supplied to the CPU. Although this function is
supported, we do not recommend that you use a higher voltage
because unstable current may be supplied to the system board
causing damage. Refer to “CPU - Vcore Select” in the Frequency/
Voltage Control section in chapter 3 for more information.
CPU Overclocking
The CPU Overclocking function allows you to adjust the processor’s
bus clock. However, overclocking may result to the processor’s or
system’s instability and are not guaranteed to provide better system
performance. Refer to “CPU Host/PCI Clock” in the Frequency/
Voltage Control section in chapter 3 for more information.
Automatic Chassis Fan Off
The chassis fan will automatically turn off once the system enters the
Suspend mode.
Dual Function Power Button
Depending on the setting in the “Soft-Off By PWRBTN” field of the
Power Management Setup, this switch will allow the system to enter
the Soft-Off or Suspend mode.
Wake-On-Ring
This feature allows the system that is in the Suspend mode or Soft
Power Off mode to wake-up/power-on to respond to calls coming
through an internal or external modem. Refer to “Wake-On-Ring
Connector” in chapter 2 and “Resume On LAN/Ring” (“Wake Up
Events” field) in the Power Management Setup section in chapter 3
for more information.
Important:
If you are using a modem add-in card, the 5VSB power source
of your power supply must support a minimum of
≥
720mA.
