X7DCL-3/X7DCL-i User's Manual
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 Power Lost Control
setting in 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 X7DCL-3/X7DCL-
i. All have an onboard System Hardware Monitor chip that supports PC health
monitoring.
Onboard Voltage Monitors
An onboard voltage monitor will scan for the CPU Cores, Chipset Voltage, +1.8V,
+3.3V, +5V, +12V, -12V, +3.3V Standby, +5V Standby and VBAT continuously.
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 dene 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-dened
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 chas-
sis temperature is too high.
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, if the system is running low
on virtual memory and there is insufcient hard drive space for saving the data,
