1.4 System Health Monitoring
The motherboard has an onboard Baseboard Management Controller (BMC) chip that
supports system health monitoring.
Onboard Voltage Monitors
The onboard voltage monitor will continuously scan crucial voltage levels. 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 dene the sensitivity of the voltage monitor. Real time readings
of these voltage levels are all displayed in BIOS.
Fan Status Monitor with Firmware Control
The system health monitor chip can check the RPM status of a cooling fan. The CPU and
chassis fans are controlled by BIOS Thermal Management through the back panel.
Environmental Temperature Control
System Health sensors monitor temperatures and voltage settings of onboard processors
and the system in real time via the IPMI interface. Whenever the temperature of the CPU or
the system exceeds a user-dened threshold, system/CPU cooling fans will be turned on to
prevent the CPU or the system from overheating
Note: To avoid possible system overheating, please be sure to provide adequate air-
ow to your system.
System Resource Alert
This feature is available when used with SuperDoctor 5® in the Windows OS or in the Linux
environment. SuperDoctor is used to notify the user of certain system events. For example,
you can congure SuperDoctor to provide you with warnings when the system temperature,
CPU temperatures, voltages and fan speeds go beyond a predened range.
1.5 ACPI Features
ACPI stands for Advanced Conguration and Power Interface. The ACPI specication denes
a exible and abstract hardware interface that provides a standard way to integrate power
management features throughout a computer system, including its hardware, operating
system and application software. This enables the system to automatically turn on and off
peripherals such as CD-ROMs, network cards, hard disk drives and printers.
