1-3 PC Health Monitoring

This section describes the PC health monitoring features of the X8SIU-F. These

features are supported by an onboard System Hardware 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, +3.3V, +5V, +12V, +3.3V Stdby, 5V Stdby, VBAT, Memory. 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 dene 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 dene an overheat temperature. When this

temperature reaches this pre-dened overheat threshold, the CPU thermal trip

feature will be activated and send a signal to the buzzer and, at the same time, the

CPU speed will be decreased.
