Built upon the functionality and the capability of the 5500/5600 Series Processor

platform, the X8DTN+/X8DTN+-LR motherboard provides the performance and

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

optimized for intensive application and high-end server platforms. The 5500/5600

Series Processor platform consists of the 5500/5600 Series (LGA 1366) pro-

cessor, the 5520 (North Bridge), and the ICH10R (South Bridge). With the Intel

QuickPath Interconnect (QPI) controller built in, the 5500/5600 Series Processor

platform is the rst dual-processing platform to offer the next generation point-

to-point system interconnect interface that replaces the current Front Side Bus

Technology and substantially enhances system performance by utilizing serial link

interconnections, allowing for increased bandwidth and scalability.

The 5520 connects to each processor through an independent QuickPath Inter-

connect link. Each link consists of 20 pairs of uni-directional differential lanes for

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

QPI link pair provides 84 signals. Each processor supports two QuickPath link,

one going to the other processor and the other to the 5520.

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

transactions. The ICH10R supports up to 6 PCI-Express ports, six SATA ports

and 10 USB connections.

In addition, the 5500/5600 Series Processor platform 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 Re-

dundancy Check (CRC), parity protection, out-of-band register access via SMBus,

memory mirroring, 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 X8DTN+/X8DTN+-

LR. All have an onboard System Hardware Monitor chip that supports PC health

monitoring. An onboard voltage monitor will scan these onboard voltages continu-

ously: CPU1 Vcore, CPU2 Vcore, +5Vin, +12V, -12V 3.3Vcc (V), and Battery Volt-

age. 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 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, be sure to provide ad-

equate airow to the system.

System Resource Alert

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

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

1-13

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.

1-5 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 Windows XP/Windows 2003/Windows 2008/

Windows Vista 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.

1-14

X8DTN+/X8DTN+-LR User's Manual

The X8DTN+/X8DTN+-LR 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 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 your power supply or motherboard, please

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

tors. Be sure to connect these power connectors to the 24-pin and the two

8-pin power connectors on your motherboard for adequate power supply

to your system. Failure to do 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.

1-7 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

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.

2-1 Static-Sensitive Devices

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

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

measures are generally suf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 specied 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.

2-3 Mounting the Motherboard into the Chassis

All motherboards have standard mounting holes to t different types of chassis.

Make sure that the locations of all mounting holes for the motherboard and the chas-

sis 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. (See the

layout on the right for mounting hole locations.)

Note: Some components are very close to the mounting holes. Please take

all necessary precautionary measures to avoid damaging these compo-

nents when installing the motherboard into the chassis.
