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 Configuration) to change this setting. The de- fault setting is Last State.

1-4 PC Health Monitoring

This section describes the PC health monitoring features of the SUPER X6DAT-G/X6DAi-G. All have an onboard System Hardware Monitor chip that supports PC health monitoring.

Onboard Voltage Monitors for the CPU Cores, Chipset Voltage, Memory Voltage, +3.3V, +5V, +12V, -12V and +5V Standby

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 define the sensi- tivity of the voltage monitor.

Fan Status Monitor with Fan Speed Control

The PC health monitor can check the RPM status of the cooling fans. The onboard 4-pin CPU and chassis fans are controlled by the thermal manage- ment functions under in the BIOS.

Environmental Temperature Control via Supero Doctor III

The thermal control sensor monitors the CPU temperature in real time and will trigger the fan to speed up whenever the CPU temperature exceeds a user-defined 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 trigger the fan to speed up to prevent any overheat damage to
