Chapter 1: Introduction

damage to the CPU. The onboard chassis thermal circuitry can monitor the overall system temperature and alert users when the chassis temperature is too high.

CPU Overheat LED and Control

This feature is available when the user enables the CPU overheat warning function in the BIOS. This allows the user to define an overheat tempera- ture.

TM2/CPU VRM Overheat

When the CPU reaches 700 C and above (Overheat), the CPU will slow down and the CPU voltage will drop to reduce CPU power consumption and VRM heat dissipation.

When CPU temperature reaches 780 C (*Default) and above, the system will go into the throttling state. The Overheat LED and Alarm Buzzer will be turned on. The CPU speed will decrease. When this happens, you can go to the Health Monitor Setting in the BIOS to reset CPU Overheat Temperature.

VRM Protection

When the CPU VRM temperature reaches the threshold preset by the user in the BIOS, the system will go into the TM2 Mode. The CPU will slow down, the VRM current will drop to prevent the VRM from overheat. (The settings are: 880C, *980C, 1080C.) (*Default)

Auto-Switching Voltage Regulator for the CPU Core

The auto-switching voltage regulator for the CPU core can support up to 20A current and auto-sense voltage IDs ranging from .8375V to 1.6V. This will allow the regulator to run cooler and thus make the system more stable.

1-5 ACPI Features

ACPI stands for Advanced Configuration and Power Interface. The ACPI specification defines a flexible and abstract hardware interface that pro- vides a standard way to integrate power management features throughout a PC system, including its hardware, operating system and application soft- ware. This enables the system to automatically turn on and off peripherals
