Built upon the functionality and the capability of the Intel 5500/5600 Series Proces-

sor and the 5520 chipset, the X8DTH-6/X8DTH-6F/X8DTH-i/X8DTH-iF mother-

board provides the performance and feature set required for dual-processor-based

high-end systems optimized for High Performance Computing (HPC)/Clustering

severs. The Intel 5520 chipset consists of dual 5520 IO hubs, and an ICH10R

(South Bridge). With the Intel QuickPath Interconnect (QPI) controller built in, the

Intel 5500/5600 Series Processor is the ﬁrst dual-processing platform to offer

the next generation point-to-point system interconnect interface to replace the

current Front Side Bus Technology, substantially enhancing system performance

and scalability.

The 5520 IO Hub connects to each processor through an independent QPI link.

Each link consists of 20 pairs of unidirectional differential lanes for transmission

and receiving in addition to a differential forwarded clock. A full-width QPI link

pair provides 84 signals.

The Intel 5520 supports up to 36 PCI Express Gen2 lanes, peer-to-peer read and

write transactions. The ICH10R provides up to seven PCI-Express ports, six SATA

ports and seven USB connections.

In addition, the Intel 5520 chipset also offers a wide range of RAS (Reliability,

Availability and Serviceability) features. These features include memory interface

ECC, x4/x8 Single Device Data Correction (SDDC), Cyclic Redundancy Check

(CRC), parity protection, out-of-band register access via SMBus, memory mirror-

ing, and Hot-plug support on the PCI-Express Interface.

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 hit 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 X8DTH-6/X8DTH-

6F/X8DTH-i/X8DTH-iF. 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, CPU1 Vtt, CPU2 Vtt, CPU1

DIMM, CPU2 DIMM, 1.1V, 1.5V, 1.8V, 3.3V, 12V, 5V, 3.3 Vsb, and VBAT. Once a

voltage becomes unstable, a warning is given or an error message is sent to the

screen. the user can adjust the voltage thresholds to deﬁne 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-deﬁned

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 chas-

sis temperature is too high.

Warning! To avoid system overheating, be sure to provide adequate air

ﬂow to the system.

System Resource Alert

This feature is available when used with Supero Doctor III in the Windows OS

1-10

Chapter 1: Introduction

environment or used with Supero Doctor II in Linux. Supero Doctor is used to

notify the user of certain system events. For example, you can also conﬁgure

Supero Doctor to provide you with warnings when the system temperature, CPU

temperatures, voltages and fan speeds go beyond a pre-deﬁned range.

1-5 ACPI Features

ACPI stands for Advanced Conﬁguration and Power Interface. The ACPI speciﬁca-

tion deﬁnes a ﬂexible 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 conﬁguration control. ACPI leverages the Plug

and Play BIOS data structures while providing a processor architecture-independent

implementation that is compatible with both Windows 2000 and Windows 2003

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.

1-11

X8DTH-6/X8DTH-6F/X8DTH-i/X8DTH-iF User's Manual

The X8DTH-6/X8DTH-6F/X8DTH-i/X8DTH-iF can accommodate 24-pin ATX power

supplies. Although most power supplies generally meet the speciﬁcations required

by the CPU, some are inadequate. In addition, the two 12V 8-pin power connections

are also required to ensure adequate power supply to the system. Also your power

supply must supply 1.5A for the Ethernet ports.

Warning: To prevent damage to the power supply or motherboard, please

use a power supply that contains a 24-pin and two 8-pin power connectors.

Be sure to connect these connectors to the 24-pin (JPW1) and the two

8-pin (JPW2,JPW3) power connectors on the motherboard for adequate

power supply to your system. Failure in doing so will void the manufacturer

warranty on your power supply and motherboard.

It is strongly recommended that you use a high quality power supply that meets ATX

power supply Speciﬁcation 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

ﬁlter 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.

1-7 Super I/O

The Super I/O supports 360 K, 720 K, 1.2 M, 1.44 M or 2.88 M disk drives and data

transfer rates of 250 Kb/s, 500 Kb/s or 1 Mb/s. It also provides two high-speed,

16550 compatible serial communication ports (UARTs). Each UART includes a 16-

byte send/receive FIFO, a programmable baud rate generator, complete modem

control capability and a processor interrupt system. Both UARTs provide legacy

speed with baud rate of up to 115.2 Kbps as well as an advanced speed with baud

rates of 250 K, 500 K, or 1 Mb/s, which support higher speed modems.

The Super I/O provides functions that comply with ACPI (Advanced Conﬁguration

and Power Interface), which includes support of legacy and ACPI power manage-

ment through an SMI or SCI function pin. It also features auto power management

to reduce power consumption.

1-8 Overview of the Winbond WPCM450 Controller (For

X8DTH-6F/iF Only)

2-1 Static-Sensitive Devices

Electrostatic Discharge (ESD) can damage electronic components. To prevent dam-

age to your system board, it is important to handle it very carefully. The following

measures are generally sufﬁcient 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 speciﬁed by the

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

explosion.

Unpacking

The motherboard is shipped in antistatic packaging to avoid static damage. When

unpacking the board, make sure the person handling it is static protected.

2-2 Motherboard Installation

All motherboards have standard mounting holes to ﬁt 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 mother-

board 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.

Pins

To modify the operation of the mother-

board, jumpers can be used to choose

between optional settings. Jumpers cre-

ate shorts between two pins to change

the function of the connector. Pin 1

is identiﬁed with a square solder pad

on the printed circuit board. See the

motherboard layout pages for jumper

locations.

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 clear-

ing CMOS.

Note: For an ATX power supply, you must completely shut down the sys-

tem, remove the AC power cord and then short JBT1 to clear CMOS.

2-9 SATA and SAS Connections

Note the following conditions when connecting the Serial ATA and ﬂoppy disk drive

cables:

• Be sure to use the correct cable for each connector. Refer to Page 1-1 for cables

that came with your shipment.

• A red mark on a wire indicates the location of pin 1.

SATA/SAS Connections (SAS: X8DTH-6/6F)

SATA/SAS Connectors

Six Serial ATA (SATA) connectors (I-SATA 0~5)

are located on the motherboard. In addition to

six SATA ports, eight SAS connections are also

located on the X8DTH-6/6F. These Serial Link

connections provide faster data transmission

than the connections of traditional Parallel ATA.

The SATA connectors are supported by the Intel

ICH10R. The SAS connectors on the X8DTH-

6/6F are supported by the LSI SAS 2 controller.

Troubleshooting

3-1 Troubleshooting Procedures

Use the following procedures to troubleshoot your system. If you have followed all

of the procedures below and still need assistance, refer to the ‘Technical Support

Procedures’ and/or ‘Returning Merchandise for Service’ section(s) in this chapter.

Note: Always disconnect the power cord before adding, changing or installing any

hardware components.

Before Power On

1. Make sure that there are no short circuits between the motherboard and

chassis.

2. Disconnect all ribbon/wire cables from the motherboard, including those for

the keyboard and mouse.

3. Remove all add-on cards.

4. Install CPU 1 ﬁrst (making sure it is fully seated) and connect the chassis

speaker and the power LED to the motherboard. (Check all jumper settings

as well.)

No Power

1. Make sure that there are no short circuits between the motherboard and the

chassis.

2. Make sure that all jumpers are set to their default positions.

3. Check that the 115V/230V switch on the power supply is properly set.

4. Turn the power switch on and off to test the system.

5. The battery on your motherboard may be old. Check to verify that it still sup-

plies ~3VDC. If it does not, replace it with a new one.

3-1

X8DTH-6/X8DTH-6F/X8DTH-i/X8DTH-iF User's Manual

No Video

1. If the power is on but you have no video, remove all the add-on cards and

cables.

2. Use the speaker to determine if any beep codes exist. Refer to the Appendix

for details on beep codes.

Losing the System’s Setup Conﬁguration

1. Make sure that you are using a high quality power supply. A poor quality

power supply may cause the system to lose the CMOS setup information.

Refer to Section 1-6 for details on recommended power supplies.

2. The battery on your motherboard may be old. Check to verify that it still sup-

plies ~3VDC. If it does not, replace it with a new one.

3. If the above steps do not ﬁx the Setup Conﬁguration problem, contact your

vendor for repairs.

Memory Errors

When a No_Memory_Beep_Code is issued by the system, check the following:

1. Make sure that the DIMM modules are properly and fully installed.

2. Check if different speeds of DIMMs have been installed and check if the BIOS

setup is conﬁgured for the fastest speed of RAM used. (It is recommended to

use the same RAM speed for all DIMMs in the system.)

3. Make sure you are using the correct type of Registered ECC or Unbuffered

BIOS

4-1 Introduction

This chapter describes the AMI BIOS Setup Utility for the X8DTH-6/X8DTH-6F/

X8DTH-i/X8DTH-iF. The AMI ROM BIOS is stored in a Flash EEPROM and can be

easily updated. This chapter describes the basic navigation of the AMI BIOS Setup

Utility setup screens.

Note: For BIOS recovery, please refer to the AMI BIOS Recovery Instruc-

tion Guide posted at http://www.supermicro.com/support/manuals/.

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 conﬁgured. Grayed-out options cannot be conﬁgured. Options in blue can be

conﬁgured 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>, ar-

row keys, etc.

Note: Options printed in Bold are default settings.

How To Change the Conﬁguration Data

The conﬁguration 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.

Hardware Health Monitor

This feature allows the user to monitor system health and review the status of each

item as displayed.

CPU Overheat Alarm

This option allows the user to select the CPU Overheat Alarm setting which de-

termines when the CPU OH alarm will be activated to provide warning of possible

CPU overheat.

Warning! 1.Any temperature that exceeds the CPU threshold tempera-

ture predeﬁned by the CPU manufacturer may result in CPU overheat or

system instability. When the CPU temperature reaches this predeﬁned

threshold, the CPU and system cooling fans will run at full speed. 2. To

avoid possible system overheating, please be sure to provide adequate

airﬂow 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 predeﬁned by the CPU manufacturer.

•

The Default Alarm: Select this setting if you want the CPU overheat alarm

(including the LED and the buzzer) to be triggered when the CPU temperature

reaches about 5^oC above the threshold temperature as predeﬁned by the CPU

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

and system cooling. In both the alarms above, please take immediate action

as shown below.

CPU 1 Temperature/CPU 2 Temperature/System Temperature

This feature displays current temperature readings for the CPUs and the System.

The following items will be displayed for your reference only:

CPU 1 Temperature/ CPU 2 Temperature

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 conﬁgured in the BIOS (Fan Speed Control).

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’.

4-16

Chapter 4: AMI BIOS

The motherboard fans and CPU will run normally as conﬁgured in the BIOS. The

fans may adjust to a faster speed depending on the Fan Speed Control settings.

High – The processor is running hot. This is a ‘caution’ level since the CPU’s ‘Tem-

perature Tolerance’ has been reached (or has been exceeded) and may activate

an overheat alarm. The system may shut down if it continues for a long period to

prevent damage to the CPU.

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 CPU thermal technology that reports absolute temperatures (Celsius/

Fahrenheit) has been upgraded to a more advanced feature by Intel in its newer

processors. The basic concept is each CPU is embedded by unique temperature

information that the motherboard can read. This ‘Temperature Threshold’ or

‘Temperature Tolerance’ has been assigned at the factory and is the baseline on

which the motherboard takes action during different CPU temperature conditions.

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 (i.e., 25^oC).

The information provided above is for your reference only. For more information

on thermal management, please refer to Intel’s Web site at www.Intel.com.

2. To avoid possible overheating, be sure to provide adequate airﬂow to the

system.

System Temperature: The system temperature will be displayed (in degrees in

Celsius and Fahrenheit) as it is detected by the BIOS.

Fan Speed Readings

This feature displays the fan speed readings from Fan1 through Fan8.

Fan Speed Control Modes

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 correlative. 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

conﬁguration or debugging. Select "Performance/PF" for better system cooling. The

4-17

X8DTH-6/X8DTH-6F/X8DTH-i/X8DTH-iF User's Manual

PF setting is recommended for high-power-consuming and high-density systems.

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 conﬁgurations. Select "Energy Saving/ES"

for best power efﬁciency and maximum quietness. The Options are: Full Speed/FS,

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

The Supero Doctor III program is a Web-based management tool that supports

remote management capability. It includes Remote and Local Management tools.

The local management is called the SD III Client. The Supero Doctor III program

included on the CDROM that came with your motherboard allows you to monitor

the environment and operations of your system. Supero Doctor III displays crucial

system information such as CPU temperature, system voltages and fan status. See

the Figure below for a display of the Supero Doctor III interface.

Note: 1 The default user name and password are ADMIN.

Note 2: In the Windows OS environment, the Supero Doctor III settings

take precedence over the BIOS settings. When ﬁrst installed, Supero Doc-

tor III adopts the temperature threshold settings previously set in BIOS. Any

subsequent changes to these thresholds must be made within Supero Doc-

tor, since the SD III settings override the BIOS settings. For the Windows

OS to adopt the BIOS temperature threshold settings, please change the

SDIII settings to be the same as those set in BIOS.
