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 confi 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
fi rst dual-processing platform that offers the next generation point-to-point system
interconnect interface 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,
memory sparing, and Hot-plug support on the PCI-Express Interface.

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 confi gure
Supero Doctor to provide you with warnings when the system temperature, CPU
temperatures, voltages and fan speeds go beyond a pre-defi ned range.
1-6 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 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 defi 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 traffi c is kept
to a minimum and users are not interrupted. The motherboard has a 3-pin header

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 Confi 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.

Installation
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 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 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 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 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.

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 defi nitions.
