1-3 PC Health Monitoring
This section describes the PC health monitoring features of the X8STi/X8STi-F/
X8STi-3F/X8STi-LN4. These features are supported by an onboard System Hard-
ware Monitor chip.
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 of this manual to change this setting. The default set-
ting is
Last State.
Onboard Voltage Monitoring
The onboard voltage monitor will scan the following voltages continuously: CPU
Core, Chipset Voltage, Memory Voltage, +1.8V, +3.3V, +3.3V standby, +5V, +5V
Standby, Vbat and ±12V. 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 define the sensitivity of the voltage monitor by using SD III.
Fan Status Monitor with Software
PC health monitoring can check the RPM status of the cooling fans via Supero
Doctor III.
CPU Overheat LED and Control
This feature is available when the user enables the CPU overheat warning feature
in the BIOS. This allows the user to define an overheat temperature. When this tem-
perature reaches this pre-defined overheat threshold, the CPU thermal trip feature
will be activated and it will send a signal to the buzzer and, at the same time, the
CPU speed will be decreased.
