1-3 PC Health Monitoring

This section describes the PC health monitoring features of the X7SBA. The

motherboard has an onboard System Hardware Monitor chip that supports PC

health monitoring.

Onboard Voltage Monitors

The onboard voltage monitor will scan the voltages for the CPU Cores, Chipset

Voltage, Memory Voltage, +1.8V, +3.3V, +3.3V Standby, +5V, +5V Standby, +12V,

and −12V continuously (via SuperO Doctor III). Once a voltage becomes unstable,

it will give a warning or send an error message to the screen. The user can adjust

the voltage thresholds to de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 dene an overheat temperature. When

the temperature reaches the prede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.

1-4 PowerCongurationSettings

This section describes features of your motherboard that deal with power and

power settings.

Slow Blinking LED for Suspend-State Indicator

When the CPU goes into a suspend state, the chassis power LED will start blinking

to indicate that the CPU is in suspend mode. When the user presses any key, the

CPU will wake-up and the LED will automatically stop blinking and remain on.
