1-3 Special Features
Recovery from AC Power Loss
BIOS provides a setting for you to determine how the system will respond when
AC power is lost and then restored to the system. You can choose for the system
to remain powered off (in which case you must hit the power switch to turn it back
on) or for it to automatically return to a power- on state. See the Advanced BIOS
Setup section to change this setting. The default setting is
Last State
.
1-4 PC Health Monitoring
This section describes the PC health monitoring features of the X7DWN+. All
have an onboard System Hardware Monitor chip that supports PC health moni-
toring.
An onboard voltage monitor will scan the following voltages continuously:
Onboard Voltage Monitors for CPU Core, Chipset Voltage, Memory Voltage, +1.8V,
+5V, +3.3V, +3.3V Standby, +5V Standby, +12V,
− 12V and VBatt. Once a voltage
becomes unstable, a warning is given or an error message is sent to the screen.
Users can adjust the voltage thresholds to de
fi ne the sensitivity of the voltage
monitor.
Fan Status Monitor with Firmware Control
The PC health monitor can check the RPM status of the cooling fans. The onboard
CPU and chassis fans are controlled by Thermal Management via BIOS (under
Hardware Monitoring in the Advanced Setting).
Environmental Temperature Control
The thermal control sensor monitors the CPU temperature in real time and will
turn on the thermal control fan whenever the CPU temperature exceeds a user-
de
fi ned threshold. The overheat circuitry runs independently from the CPU. Once
it detects that the CPU temperature is too high, it will automatically turn on the
thermal fan control to prevent any overheat damage to the CPU. The onboard
chassis thermal circuitry can monitor the overall system temperature and alert
users when the chassis temperature is too high.
CPU Fan Auto-Off in Sleep Mode
The CPU fan becomes active when the power is turned on. It continues to operate
when the system enters the Standby mode. When in the sleep mode, the CPU will
not run at full power, thereby generating less heat.
System Resource Alert
This feature is available when used with Supero Doctor III in the Windows OS
environment or used with Supero Doctor II in Linux. Supero Doctor is used to
notify the user of certain system events. For example, you can also con
