Health
Monitoring
This section describes the PC health monitoring features of the SUPER P4SPA+/
P4SPE. The motherboard has an onboard System Hardware Monitor chip that
supports PC health monitoring.
Eight Onboard Voltage Monitors for the CPU Core, Chipset Voltage,
+3.3V, +3.3V standby,
+
5V, +5V standby, Vbat and
±
12V
The onboard voltage monitor will scan these voltages continuously. Once a volt-
age 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/Software On/Off Control
The PC health monitor can check the RPM status of the cooling fans. The onboard
3-pin fans are controlled by the power management functions.
CPU Overheat LED and Control
This feature is available when the user enables the CPU overheat warning function
in the BIOS. This allows the user to defi ne an overheat temperature. When this
temperature reaches the threshold, the CPU thermal trip feature will be activated
and it will send a signal to the Speaker LED and the CPU speed will be decreased
as well.
Hardware BIOS Virus Protection
The system BIOS is protected by Hardware so that no virus can infect the BIOS
area. The user can only change the BIOS contents through the fl ash utility provided
by Super Micro. This feature can prevent viruses from infecting the BIOS area and
destroying valuable data.
Auto-Switching Voltage Regulator for the CPU Core
The 3-phase-switching voltage regulator for the CPU core can support up to 60A
current and auto-sense voltage IDs ranging from 0.875 V to 1.6V. This will allow
the regulator to run cooler and thus make the system more stable.

Confi 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.
