1-3 PC Health Monitoring
This section describes the PC health monitoring features of the H8DSL-HTi. The
serverboard has an onboard System Hardware Monitor chip that supports PC
health monitoring.
Onboard Voltage Monitors for the CPU core voltages, +5Vin,
+12Vin, -12V, DDR voltages, 1.2V for HT, 2.5V, 5Vstby, 2.5Vstby
and battery voltage
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 defi ne the sensitivity of the voltage
monitor. Real time readings of these voltage levels are all displayed in the System
Health Monitor section of BIOS.
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 defi ne 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 3-phase-switching voltage regulator for the CPU core can support up to 80A 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.
