Chapter 1: Introduction

1-3 Chipset Overview

Built upon the capability of the Intel 5520 platform, the X8DT3/X8DTi/X8DT3-F/

X8DTi-F/X8DT3-LN4F/X8DTi-LN4F motherboard provides the performance and

feature set required for dual-processor-based high-end systems with congura-

tion optimized for workstations, High Performance Computing (HPC) systems,

and intensive applications. The 5520 platform consists of the 5500/5600 Series

(LGA 1366) processor, the 5520 (North Bridge), and the ICH10R (South Bridge).

With the QuickPath Interconnect (QPI) controller built in, the 5520 platform is the

rst dual-processing platform that offers the next generation point-to -point system

interconnect inter face to replace the current Front Side Bus Technology, substan-

tially enhancing system performance with increased bandwidth and scalability.

The 5520 North Bridge connects to each processor through an independent Quick-

Path Interconnect link. Each link consists of 20 pairs of unidirectional differential

lanes for data transferring in addition to a differential forwarded clock. A full-width

QuickPath interconnect link pair provides 84 signals. Each processor supports two

QuickPath links, one going to the other processor and the other to the 5520.

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

and write transactions. The ICH10R provides up to 6 PCI-Express ports, six SATA

ports and 10 USB connections.

In addition, the 5520 platform also offers a wide range of RAS (Reliability, Avail-

ability 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 mirroring, and

memory sparing.

1-4 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.

1-5 PC Health Monitoring

This section describes the PC health monitoring features of the X8DT3/X8DTi/

X8DT3-F/X8DTi-F/X8DT3-LN4F/X8DTi-LN4F. All have an onboard System Hard-

ware Monitor chip that supports PC health monitoring. An onboard voltage monitor

will scan these onboard voltages continuously: CPU1 Vcore/CPU2 Vcore, CPU1

DIMM/CPU2 DIMM, 1.5V, 3.3Vcc (V), 3.3V SB (V), 12Vcc (V), 5Vin, and Battery

Voltage. Once a voltage becomes unstable, a warning is given or an error mes-

sage is sent to the screen. Users can adjust the voltage thresholds to de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-de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 chas-

sis temperature is too high.

Warning: To avoid possible system overheating, please be sure to provide

adequate airow to your 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 congure

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

temperatures, voltages and fan speeds go beyond a pre-dened range.

1-6 ACPI Features

ACPI stands for Advanced Conguration and Power Interface. The ACPI specica-

tion denes a 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 conguration control. ACPI leverages the Plug

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

implementation that is compatible with the Windows XP/2003/2008/Vista Operating

System.

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.

Wake-On-LAN (WOL)

Wake-On-LAN is dened as the ability of a management application to remotely

power up a computer that is powered off. Remote PC setup, up-dates and asset

tracking can occur after hours and on weekends so that daily LAN trafc is kept

to a minimum and users are not interrupted. The motherboard has a 3-pin header

1-11

X8DT3/X8DTi/X8DT3-F/X8DTi-F/X8DT3-LN4F/X8DTi-LN4F User's Manual

(WOL) to connect to the 3-pin header on a Network Interface Card (NIC) that has

WOL capability. In addition, an onboard LAN controller can also support WOL

without any connection to the WOL header. The 3-pin WOL header is to be used

with a LAN add-on card only.

Note: Wake-On-LAN requires an ATX 2.01 (or above) compliant power

supply.

1-7 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.

The X8DT3/X8DTi/X8DT3-F/X8DTi-F/X8DT3-LN4F/X8DTi-LN4F can accommodate

24-pin ATX power supplies. Although most power supplies generally meet the

specications 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 (JPW3) and the two

8-pin (JPW1,JPW2) 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 Specication 2.02 or above. It must also be SSI compliant (For more

information, please refer to the web site at http://www.ssiforum.org/). Additionally, in

areas where noisy power transmission is present, you may choose to install a line

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.

1-8 Super I/O

The disk drive adapter functions of the Super I/O chip include a oppy disk drive

controller that is compatible with industry standard 82077/765, a data separator,

write pre-compensation circuitry, decode logic, data rate selection, a clock genera-

tor, drive interface control logic and interrupt and DMA logic. The wide range of

functions integrated onto the Super I/O greatly reduces the number of components

required for interfacing with oppy disk drives. 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

1-12

Chapter 1: Introduction

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 Conguration

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.

1-9 Overview of the Winbond WPCM450 Controller (For
X8DT3/i-F/X8DT3/i-LN4F Only)

The Winbond WPCM450 Controller is a Baseboard Management Controller (BMC)

that supports the 2D/VGA-compatible Graphics Core with the PCI interface,

Virtual Media, and Keyboard/Video/Mouse Redirection (KVMR) modules. With

blade-oriented Super I/O capability built-in, the WPCM450 Controller is ideal for

legacy-reduced server platforms.

The WPCM450 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, and Platform Environment Control Interface (PECI) buses.

Fan Headers

This motherboard has six chassis/system

fan headers (Fan1 to Fan6) and two CPU

fans (Fan7/Fan8) on the motherboard. All

these 4-pin fans headers are backward

compatible with the traditional 3-pin fans.

However, fan speed control is available

for 4-pin fans only. The fan speeds are

controlled by Thermal Management via

Hardware Monitoring in the Advanced

Setting in the BIOS. (The Default setting

is Disabled.) See the table on the right for

pin denitions.

Chassis Intrusion

A Chassis Intrusion header is located

at JL1 on the motherboard. Attach an

appropriate cable from the chassis to

inform you of a chassis intrusion when

the chassis is opened.

Chapter 2: Installation

Explanation of Jumpers

To modify the operation of the mother-

board, 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 identi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 the jumper is

off the pins.

GLAN Enable/Disable

Use JPL1 to enable or disable the GLAN

Ports 1 & 2. Use JPL2 to enable or disable

the GLAN Ports 3 & 4 on the X8DT3/i-

LN4F. See the tables on the right for

jumper settings. The default setting is

Enabled.

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.

Watch Dog Enable/Disable

Watch Dog (JWD) is a system monitor that

can reboot the system when a software ap-

plication 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

Chapter 4: AMI BIOS

Chapter 4

BIOS

4-1 Introduction

This chapter describes the AMI BIOS Setup Utility for the X8DT3/X8DTi/X8DT3-

LN4/X8DTi-LN4. 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.

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 congured. Grayed-out options cannot be congured. Options in blue can be

con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

ing the LED and the buzzer) to be triggered as soon as the CPU temperature

reaches the CPU overheat threshold as predened 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 5oC above the threshold temperature as predened 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.

CPU1 Temperature/CPU2 Temperature/System Temperature

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

The following items will be displayed for your reference only:

CPU1 Temperature/CPU2 Temperature

The CPU thermal technology that reports absolute temperatures (Celsius/Fahr-

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

4-17

X8DT3/X8DTi/X8DT3-F/X8DTi-F/X8DT3-LN4F/X8DTi-LN4F User's Manual

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

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

perature Tolerance’ has been assigned at the factory and is the baseline on which

the motherboard takes action during different CPU temperature conditions (i.e., by

increasing CPU Fan speed, triggering the Overheat Alarm, etc). Since CPUs can

have different ‘Temperature Tolerances’, the installed CPU can now send informa-

tion 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., 25oC). 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 con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 con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 ‘Tem-

perature 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 Web site at

www.Intel.com.

System Temperature: The system temperature will be displayed (in degrees in
Celsius and Fahrenheit) as it is detected by the BIOS.

System FAN Monitor

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

conguration or debugging. Select "Performance/PF" for better system cooling. The

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 congurations. Select "Energy Saving/ES"

for best power efciency 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 rst 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-
