1-4 PC Health Monitoring

This section describes the PC health monitoring features of the H8DMT+/H8DMT-

INF+. The motherboard has an onboard System Hardware Monitor chip that sup-

ports PC health monitoring.

Onboard Voltage Monitors

The onboard voltage monitor will continuously scan crucial voltage levels. 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 volt-

age monitor. 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, 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 0.8 V to 1.55V. This will allow the regulator

to run cooler and thus make the system more stable.

1-5 Power Conﬁ guration Settings

This section describes the features of your motherboard 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.
