1-3 PC Health Monitoring
This section describes the PC health monitoring features of the P8SC8/ P8SCi. 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, +5V, +5V Standby, 1.5V, 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 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/Fan Fail LED and Control
This feature is available when the user enables the CPU overheat/Fan Fail warning function in the BIOS. This allows the user to define an overheat temperature. When this temperature is exceeded or when a fan failure occurs, then, the Overheat/Fan Fail warning LED is triggered.
Auto-Switching Voltage Regulator for the CPU Core
The
1-4 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
