PC Health Monitoring
This section describes the PC health monitoring features of the P8SCT.
The motherboard has an onboard System Hardware Monitor chip that sup-
ports PC health monitoring.
Seven Onboard Voltage Monitors for the CPU Core, +3.3V,
+++++
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 via Supero Doctor III.
Fan Status Monitor with Firmware Speed Control
The PC health monitor can check the RPM status of the cooling fans. The
onboard fans are controlled by thermal management via BIOS.
CPU Overheat 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 the temperature reaches the pre-defined OH temperature or
when a fan failure occurs, then, the Overheat warning LED is triggered.
Auto-Switching Voltage Regulator for the CPU Core
The 4-phase-switching voltage regulator for the CPU core can support
auto-sense voltage IDs ranging from 0.875 V to 1.6V. This will accommo-
date different CPUs with different core voltage requirements. It will also
allow the regulator to run cooler and thus make the system more stable.

CPU Thermal Management
Thermal Management 2 (TM2)
When TM2 is enabled in the BIOS and the CPU temperature reaches a pre-
defined threshold, a thermal monitoring mechanism will reduce the process
speed by lowering the bus-to-core ratio of the processor core clock and
decrease the voltage input by changing the CPU VID. This combination of
reduced CPU bus frequency and CPU VID effectively decreases CPU power
