PC Health Monitoring
This section describes the PC health monitoring features of the X7SBi. The
motherboard has an onboard System Hardware Monitor chip that supports PC
health monitoring.
Onboard Voltage Monitors for the CPU Cores, Chipset Voltage,
Memory Voltage, +1.8V, +3.3V, +3.3V Standby, +5V, +5V Standby,
+12V, and −12V (via SuperO Doctor III)
The onboard voltage monitor will scan these voltages continuously. Once a
voltage becomes unstable, it will give a warning or send an error message to the
screen. Users can adjust the voltage thresholds to defi ne the sensitivity of the
voltage monitor.
Fan Status Monitor with Firmware Speed Control
The PC health monitor can check the RPM status of the cooling fans. The on-
board fans are controlled by Thermal Management via Hardware Monitoring in
the BIOS.
CPU Overheat/Fan Fail LED and Control
This feature is available when the user enables the CPU overheat warning func-
tion in the BIOS. This allows the user to defi ne an overheat temperature. When
the temperature reaches the predefi ned threshold, the CPU thermal trip feature
will be activated and it will send a signal to the Speaker LED and, at the same
time, the CPU speed will be decreased. It will also activate the alarm if a fan
failure occurs.
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 BIOS chapter to change this setting. The default setting is
Last State.
