PC Health Monitoring
This section describes the PC health monitoring features of the SUPER
P4SPA+/P4SPE. The motherboard has an onboard System Hardware Moni-
tor 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
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 sensi-
tivity 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 define an overheat tempera-
ture. 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, at
the same time, the CPU speed will be decreased.
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 content through the flash
utility provided by Supermicro. This feature can prevent viruses from in-
fecting 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.
