1-3 PC Health Monitoring

This section describes the PC health monitoring features of the H8DSR-8/H8DSR-

i. The serverboard has an onboard System Hardware Monitor chip that supports

PC health monitoring.

Onboard Voltage Monitors for the CPU core voltages, +2.5V, +5V,

+1.2V, ±12V 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.
