Chapter 1: Introduction
1-3 Chipset Overview
Built upon the functionality and the capability of the 5400 chipset, the X7DWE
motherboard provides the performance and feature set required for quad-proces-
sor or dual-processor-based high-end systems with confi guration options opti-
mized for complex storage platforms. The 5400 chipset supports single or dual
Intel Quad-Core/Dual-Core Xeon 5400/5300/5200/5100 Series processor with
front side bus speeds of up to 1.6 GHz. The chipset consists of the 5400 Memory
Controller Hub (MCH) for the host bridge and the 631xESB/632xESB I/O Controller
Hub (Enterprise South Bridge 2-ESB2) for the I/O subsystem.
The Intel 5400 MCH (North Bridge)
The 5400 MCH (North Bridge) provides two FSB processing interfaces, four fully
buffered (FBD) DIMM memory channels, PCI-Express bus interfaces confi gurable
to form x8 or x16 ports, an ESB2 South Bridge Interface (ESI) and SMBus Inter-
faces for system management, and DIMM Serial Presence Detect (SPD). The peak
bandwidth for each FBD channel is 8 GB/s for DDR2 800/667/533 FBD memory,
giving a total memory size of 32 GB.
The Intel 631xESB/632x ESB I/O Controller Hub-ESB2
(South Bridge)
The 631xESB/632xESB I/O Controller Hub (Enterprise South Bridge 2) integrates
an Ultra ATA 100 Controller, six Serial ATA host controller ports, one EHCI host
controller, seven external USB 2.0 ports, an LPC interface controller, and a fl ash
BIOS interface controller. Additionally, the ESB 2 chip also contains a PCI inter-
face controller, integrated LAN controller, and an ESI for communication with the
MCH. The Intel ESB2 offers the data buffering and interface arbitration capabili-
ties required for a high-end system to constantly operate effi ciently and maintain
peak performance.
Compliant with the ACPI platform, the ESB2 supports the Full-On, Stop-Grant,
Suspend-to-RAM, Suspend-to-Disk, and Soft-Off power management states.
Combined with the functionality offered by the onboard LAN controller, the ESB2
also supports alert systems for remote management.
With the 5400 chipset built in, the X7DWE offers a superb solution for intense com-
puting and complex I/O environments, and is ideal for high-end server systems.

X7DWE User's Manual
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 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.
1-5 PC Health Monitoring
This section describes the PC health monitoring features of the X7DWE. All have
an onboard System Hardware Monitor chip that supports PC health monitoring. An
onboard voltage monitor will scan these onboard voltages continuously: CPU Core,
Chipset Voltage, Memory Voltage, +1.8V, +5V, +3.3V, +3.3V Standby, +5V Standby,
+12V, −12V and VBatt. 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 chas-
sis temperature is too high.
CPU Fan Auto-Off in Sleep Mode
The CPU fan becomes active when the power is turned on. It continues to operate
when the system enters the Standby mode. When in the sleep mode, the CPU will
not run at full power, thereby generating less heat.
1-10
Chapter 1: Introduction
CPU Overheat LED and Control
This feature is available when the user enables the CPU overheat warning func-
tion in the BIOS. This allows the user to defi ne an overheat temperature. When
the CPU temperature passes this threshold, both the overheat fan and the warning
LED are triggered.
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
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 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.
External Modem Ring-On
Wake-up events can be triggered by a device such as the external modem ringing
when the system is in the SoftOff state. Note that external modem ring-on can
only be used with an ATX 2.01 (or above) compliant power supply.
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
(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 X7DWE can accommodate 24-pin ATX power supplies. Although most power
supplies generally meet the specifi cations required by the CPU, some are inad-
equate. 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.
Note: The + 12V 8-pin CPU Power Connector (JPW2) is also required to
support Intel 64-bit CPUs. Failure to provide this extra power will result in
CPU PWR Failure. See Section 2-5 for details on connecting the power
supply.
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.
1-8 Super I/O
The disk drive adapter functions of the Super I/O chip include a fl 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 fl 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 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.

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 Processor and Heatsink Installation
When handling the processor package, avoid placing direct pressure on
the label area of the fan.
Notes:
1.
Always connect the power cord last and always remove it before adding, re-
moving or changing any hardware components. Make sure that you install the
processor into the CPU socket before you install the CPU heatsink.
2.
Intel's boxed Xeon CPU package contains the CPU fan and heatsink assem-
bly. If you buy a CPU separately, make sure that you use only Intel-certifi ed
multi-directional heatsink and fan.
3.
Make sure to install the motherboard into the chassis before you install the
CPU heatsink and fan.)
4.
When purchasing an LGA 771 CPU or when receiving a motherboard with an
LGA 771 CPU pre-installed, make sure that the CPU plastic cap is in place,
and none of the CPU pins are bent; otherwise, contact the retailer immedi-
ately.
