1-3 Special Features

Recovery from AC Power Loss

BIOS provides a setting for you to determine how the system will respond when AC
power is lost and then restored to the system. You can choose for the system to
remain powered off (in which case you must press the power switch to turn it back
on) or for it to automatically return to a power- on state. See the Advanced BIOS
Setup section to change this setting. The default setting is Last State.

1-4 PC Health Monitoring

This section describes the PC health monitoring features of the X8DTT-H+ series
motherboard. All have an onboard System Hardware Monitor chip that supports
PC health monitoring. An onboard voltage monitor will scan these onboard volt­ages continuously: CPU1 VCore, CPU2 VCore, +5Vin, 12Vcc (V), VP1 DIMM,
VP2 DIMM, +3.3Vcc (V), and Battery Voltage. Once a voltage becomes unstable,
a warning is given or an error message is sent to the screen. Users can adjust the
voltage thresholds to defi ne the sensitivity of the voltage monitor.

Fan Status Monitor with Firmware Control

The PC health monitor can check the RPM status of the cooling fans. The onboard
CPU and chassis fans are controlled by Thermal Management via BIOS (under
Hardware Monitoring in the Advanced Setting).

Environmental Temperature Control

The thermal control sensor monitors the CPU temperature in real time and will turn
on the thermal control fan whenever the CPU temperature exceeds a user-defi ned
threshold. The overheat circuitry runs independently from the CPU. Once it detects
that the CPU temperature is too high, it will automatically turn on the thermal fan
control to prevent any overheat 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.

To avoid possible system overheating, please be sure to provide adequate
airfl ow to your system.

System Resource Alert

This feature is availab le when used with S upero Doctor III in the Windows OS
environment or used with Supero Doctor II in Linux. Supero Doctor is used to
notif y the user of cer tain system events. For example, you can also confi gure

1-5 ACPI Features

ACPI stands for Advanced Confi guration and Power Interface. The ACPI specifi ca-
tion defi nes a fl exible and abstract hardware interface that provides a standard
way to integrate power management features throughout a PC system, including
its hardware, operating system and application software. This enables the system
to automatically turn on and off peripherals such as CD-ROMs, network cards, hard
disk drives and printers.

In addition to enabling operating system-directed power management, ACPI
provides a generic system event mechanism for Plug and Play and an operating
system-independent interface for confi guration control. ACPI leverages the Plug
and Play BIOS data structures while providing a processor architecture-independent
implementation that is compatible with Windows XP/Windows 2008/Windows Vista/
Windows 7 Operating Systems.

Slow Blinking LED for Suspend-State Indicator

When the CPU goes into a suspend state, the chassis power LED will start blinking
to indicate that the CPU is in suspend mode. When the user presses any key, the
CPU will wake-up and the LED will automatically stop blinking and remain on.

Main Switch Override Mechanism

When an ATX power supply is used, the power button can function as a system
suspend button to make the system enter a SoftOff state. The monitor will be
suspended, and the hard drive will spin down. Pressing the power button again
will cause the whole system to wake-up. During the SoftOff state, the ATX power
supply provides power to keep the required circuitry in the system "alive." In case
the system malfunctions and you want to turn off the power, just press and hold
the power button for 4 seconds. This option can be set in the Power section of the
BIOS Setup routine.

1-6 Power Supply

As with all computer products, a stable power source is necessary for proper and
reliable operation. It is even more important for processors that have high CPU
clock rates.

It is strongly recommended that you use a high quality power supply that meets ATX
power supply Specifi cation 2.02 or above. It must also be SSI compliant (For more

information, please refer to the website at http://www.ssiforum.org/). Additionally, in
areas where noisy power transmission is present, you may choose to install a line
fi lter to shield the computer from noise. It is recommended that you also install a
power surge protector to help avoid problems caused by power surges.

Note: The X8DTT-H+ series motherboard supports proprietary power
connectors. Please refer to Page 2-16 for detailed information on power
supply for the motherboard.

1-7 Overview of the Winbond WPCM450 Controller

The Winbond WPCM450, a Baseboard Management Controller (BMC), supports
2D/VGA-compatible Graphics Core, PCI interface, Virtual Media, and Keyboard/
Video/Mouse (KVM) Redirection modules.

The WPCM450 BMC interfaces with the host system via a PCI interface to com­municate with the graphics core. It supports USB 2.0 and 1.1 for remote keyboard/
mouse/virtual media emulation. It also provides LPC interface to control Super IO
functions. The WPCM450 is connected to the network via an external Ethernet
PHY module.

The WPCM450 communicates with onboard components via six SMBus interfaces,
fan control, Platform Environment Control Interface (PECI) buses.

2-1 Static-Sensitive Devices

Electrostatic Discharge (ESD) can damage electronic com ponents. T o prevent dam­age to your system board, it is important to handle it very carefully. The following
measures are generally suffi cient to protect your equipment from ESD.

Precautions

Use a grounded wrist strap designed to prevent static discharge.•

Touch a grounded metal object before removing the board from the antistatic •
bag.

Handle the board by its edges only; do not touch its components, peripheral

•

chips, memory modules or gold contacts.

When handling chips or modules, avoid touching their pins.

•

Put the motherboard and peripherals back into their antistatic bags when not •
in use.

For grounding purposes, make sure your computer chassis provides excellent

•

conductivity between the power supply, the case, the mounting fasteners and
the motherboard.

Use only the correct type of onboard CMOS battery as specifi ed by the

•

manufacturer. Do not install the onboard battery upside down to avoid possible
explosion.

Unpacking

The motherboar d is shipped i n a ntistati c pa ckaging to avoid static da mage. When
unpacking the board, make sure the person handling it is static protected.

2-2 Motherboard Installation

All motherboards have standard mounting holes to fi t different types of chassis.
Make sure that the locations of all the mounting holes for both motherboard and
chassis match. Although a chassis may have both plastic and metal mounting
fasteners, metal ones are highly recommended because they ground the mother­board to the chassis. Make sure that the metal standoffs click in or are screwed in
tightly. Then use a screwdriver to secure the motherboard onto the motherboard
tray. Note: Some components are very close to the mounting holes. Please take
precautionary measures to prevent damage to these components when installing
the motherboard to the chassis.

The X8DTT-H+ Series motherboard has a
cooling fan on the motherboard. This 4-pin fan
header is backward compatible with the tradi­tional 3-pin fan. However, fan speed control is
only available for a 4-pin fan. The fan speeds
are controlled by Thermal Management via
Hardware Monitoring in the Advanced Setting
in the BIOS. (The Default setting is Disabled.)

Explanation of Jumpers

To modify the operation of the motherboard,
jumpers can be used to choose between optional
settings. Jumpers create shorts between two pins
to change the function of the connector. Pin 1 is
identifi ed with a square solder pad on the printed
circuit board. See the motherboard layout pages for
jumper locations.

Note: On two pin jumpers, "Closed"
means the jumper is on and "Open"
means th e jumpe r is of f the pi ns.

Chapter 2: Installation

CMOS Clear

JBT1 is used to clear CMOS. Instead of pins, this "jumper" consists of contact pads
to prevent the accidental clearing of CMOS. To clear CMOS, use a metal object such
as a small screwdriver to touch both pads at the same time to short the connection.
Always remove the AC power cord from the system before clearing CMOS.

Note: For an ATX power supply, you must completely shut down the sys­tem, remove the AC power cord and then short JBT1 to clear CMOS.

Watch Dog Enable/Disable

Watch Dog (JWD1) is a system monitor that
reboots the system when a software applica­tion hangs. Close Pins 1-2 to reset the system
if an application hangs. Close Pins 2-3 to
generate a non-maskable interrupt signal for
the application that hangs. See the table on
the right for jumper settings. Watch Dog must
also be enabled in the BIOS.

4-1 Introduction

This chapter describes the AMI BIOS Setup Utility for the X8DTT-H+/-HF+/-HEF+/­HIBXF+/-HIBQF+. It also provide instructions on how to navigate the AMI BIOS
Setup Utility setup screens. The AMI ROM BIOS is stored in a Flash EEPROM
and can be easily updated.

Starting BIOS Setup Utility

To enter the AMI BIOS Setup Utility screens, press the <Delete> key while the
system is booting up.

Note: In most cases, the <Delete> key is used to invoke the AMI BIOS
setup screen. There are a few cases when other keys are used, such as
<F1>, <F2>, etc.

Each main BIOS menu option is described in this manual. The Main BIOS setup
menu screen has two main frames. The left frame displays all the options that can
be confi gured. Grayed-out options cannot be confi gured. Options in blue can be
confi gured by the user. The right frame displays the key legend. Above the key
legend is an area reserved for a text message. When an option is selected in the
left frame, it is highlighted in white. Often a text message will accompany it. (Note:
The AMI BIOS has default text messages built in. Supermicro retains the option to
include, omit, or change any of these text messages.)

The AMI BIOS Setup Utility uses a key-based navigation system called "hot keys."
Most of the AMI BIOS setup utility "hot keys" can be used at any time during the
setup navigation process. These keys include <F1>, <F10>, <Enter>, <ESC>, ar­row keys, etc.

Note: Options printed in Bold are default settings.

How To Change the Confi guration Data

The confi guration data that determines the system parameters may be changed by
entering the AMI BIOS Setup utility. This Setup utility can be accessed by pressing
<Del> at the appropriate time during system boot.

threshold, the CPU and system cooling fans will run at full speed. 2. To
avoid possible system overheating, please be sure to provide adequate
airfl ow to your system.

The options are:

The Early Alarm: Select this setting if you want the CPU overheat alarm (includ-

•

ing the LED and the buzzer) to be triggered as soon as the CPU temperature
reaches the CPU overheat threshold as predefi ned by the CPU manufacturer.

manufacturer to give the CPU and system fans additional time needed for CPU
and system cooling.

CPU Temperature/System Temperature

o

C above the threshold temperature as predefi ned by the CPU

This feature displays current temperature readings for the CPU and the System.
The following items will be displayed for your reference.

CPU Temperature

The CPU thermal technology that reports absolute temperatures (Celsius/Fahren­heit) has been upgraded to a more advanced feature by Intel in its newer processors.

4-17

X8DTT-H+/-HF+/-HEF+/-HIBXF+/-HIBQF+ User’s Manual

The basic concept is each CPU is embedded by unique temperature information that
the motherboard can read. This ‘Temperature Threshold’ or ‘Temperature T olerance’
has been assigned at the factory and is the baseline on which the motherboard
takes action during different CPU temperature conditions (e.g., by increasing CPU
Fan speed, triggering the Overheat Alarm, etc). Since CPUs can have different
‘Temperature Tolerances’, the installed CPU can now send information to the moth­erboard what its ‘Temperature Tolerance’ is, and not the other way around. This
results in better CPU thermal management.

Supermicro has leveraged this feature by assigning a temperature status to certain
thermal conditions in the processor (Low, Medium and High). This makes it easier
for the user to understand the CPU’s temperature status, rather than by just simply
seeing a temperature reading (e.g., 25

o

C). The CPU Temperature feature will display

the CPU temperature status as detected by the BIOS:
Low – This level is considered as the ‘normal’ operating state. The CPU temperature

is well below the CPU ‘Temperature Tolerance’. The motherboard fans and CPU will
run normally as confi gured in the BIOS (Fan Speed Control).

User intervention: No action required.
Medium – The processor is running warmer. This is a ‘precautionary’ level and

generally means that there may be factors contributing to this condition, but the CPU
is still within its normal operating state and below the CPU ‘Temperature Tolerance.’
The motherboard fans and CPU will run normally as confi gured in the BIOS. The
fans may adjust to a faster speed depending on the Fan Speed Control settings.

User intervention: No action is required. However, consider checking the CPU fans
and the chassis ventilation for blockage.

High – The processor is running hot. This is a ‘caution’ level since the CPU’s ‘Tem­perature Tolerance’ has been reached (or has been exceeded) and may activate
an overheat alarm.

User intervention: If the system buzzer and Overheat LED has activated, take action
immediately by checking the system fans, chassis ventilation, and room temperature
to correct any problems.

Notes: 1. The system may shut down if it continues for a long period to
prevent damage to the CPU.

2. The information provided above is for your reference only. For more
information on thermal management, please refer to Intel’s Website at
http://www.Intel.com.

System Temperature: The system tem peratu re will be d isplayed (i n degre es in
Celsiu s and Fahrenh eit) as detecte d by the BIO S.

Fan Speed Control Monitor

This feature allows the user to decide how the system controls the speeds of the
onboard fans. The CPU temperature and the fan speed are correlated. When the
CPU on-die temperature increases, the fan speed will also increase for effective
system cooling. Select "Full Speed/FS" to allow the onboard fans to run at full
speed for maximum cooling. The FS setting is recommended for special system
confi guration or debugging. Select "Performance/PF" for better system cooling.
Select "Balanced/BL" for the onboard fans to run at a speed that will balance the
needs between system cooling and power saving. The BL setting is recommended
for regular systems with normal hardware confi gurations. Select "Energy Saving/ES"
for best power effi ciency and maximum quietness. The Options are: Full Speed/

FS, Performance/PF, Balanced/BL, and Energy Saving/ES.
