1-3 PC Health Monitoring
This section describes the PC health monitoring features of the H8QM3-2/H8QMi-
2. The serverboard has an onboard System Hardware Monitor chip that supports
PC health monitoring.
Onboard Voltage Monitors for four CPU cores, Hyper Transport
(1.2V), memory (1.8V), chipset (1.5V)
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 moni-
tor. Real time readings of these voltage levels are all displayed in 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 5-phase-switching voltage regulator for the CPU core can support up to 100A
and auto-sense voltage IDs. This will allow the regulator to run cooler and thus
make the system more stable.
1-4 Power Confi guration Settings
This section describes the features of your serverboard that deal with power and
power settings.
Microsoft OnNow
The OnNow design initiative is a comprehensive, system-wide approach to system
and device power control. OnNow is a term for a PC that is always on but appears
to be off and responds immediately to user or other requests.
