Special Features

Recovery from AC Power Loss
The feature allows the user to set the power state after a power outage. You can
select Power-Off for the system power to remain off after a power loss. Select
Power-On for the system power to be turned on after a power loss. Select Last

PC Health Monitoring

This section describes the PC health monitoring features of the X7DBT/X7DBT-
INF/X7DGT/X7DGT-INF. All models have an onboard System Hardware Monitor
chip that supports PC health monitoring.
Onboard Voltage Monitors for CPU Cores, Memory Voltage,
Chipset Voltage (+1.5V),+1.8V, +3.3V, +5V, +12V, −12V, +3.3V
Standby, +5V standby, HT and VBAT
An onboard voltage monitor will scan these voltages 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 defi 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 2 (TM2) 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-defi 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 chas-
sis temperature is too high.
