1-3 PC Health Monitoring
This section describes the PC health monitoring features of the SUPER
P4SCT/P4SCT+/P4SCT+II. The motherboard has an onboard System Hard-
ware Monitor chip that supports PC health monitoring.
Eight Onboard Voltage Monitors for the CPU Core, +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, using Supermicro's Monitoring Software-Supero
Doctor.
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.
Environmental Temperature Control
The P4SCT/P4SCT+/P4SCT+II has a CPU "thermal trip" feature. A thermal
control sensor monitors the CPU temperature in real time and will send a
signal to shut down the system whenever the CPU temperature exceeds a
certain threshold. This works to protect the CPU from being damaged by
overheating.
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 is exceeded, the CPU thermal trip feature will
activate and shut down the system.
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 4-phase-switching voltage regulator for the CPU core can support up to
60A current and auto-sense voltage IDs ranging from 1.1V to 1.85V. This
will allow the regulator to run cooler and thus make the system more stable.
