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 (Peripheral Device Confi guration) 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 SUPER X6DH3-
G2/X6DHi-G2.All have an onboard System Hardware Monitor chip that supports
PC health monitoring.
Onboard Voltage Monitors for the CPU Cores, +3.3V, +5V, +12V,
and -12V
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 via BIOS and SDIII
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 and Supero
Doctor III.
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. It can continue
to monitor for overheat conditions even when the CPU is in sleep mode. Once it
detects that the CPU temperature is too high, it will automatically turn on the ther-
mal control fan 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 activates when the power is turned on. It continues to operate when
the system enters Standby mode. When in sleep mode, the CPU will not run at
full power, thereby generating less heat.
