Chapter 1: Introduction
1-2 Chipset Overview
Built upon the functionality and the capability of the 5400 chipset, the X7DWU
motherboard provides the performance and feature set required for quad-processor
or dual-processor-based high-end systems with confi guration options optimized for
complex storage platforms. The 5400 chipset supports single or dual Intel QuadCore/Dual-Core Xeon 5400 Series/5300LV Series/5200 Series/5100LV 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 EB2 South Bridge Interface (ESI) and SMBus Interfaces
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. The
PCI-Express interfaces can be confi gured to form x8 or x16 ports that can operate
up to Gen-2 speeds in x16 confi guration for enhanced graphics applications.
The Intel 631x/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, fi ve 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 interface
controller, integrated LAN controller, an ASF controller and an ESI for communication with the MCH. The Intel ESB2 offers the data buffering and interface arbitration
capabilities 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 X7DWU offers a superb solution for intense computing and complex I/O environments, and is ideal for high-end server systems.

1-4 PC Health Monitoring
This section describes the PC health monitoring features of the X7DWU. All have
an onboard System Hardware Monitor chip that supports PC health monitoring.
Onboard Voltage Monitors
An onboard voltage monitor will scan CPU Cores, Chipset Voltage, +1.8V, +3.3V,
+5V, +12V, -12V, +3.3V Standby, +5V Standby and VBAT continuously. 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 chassis temperature is too high.
1-10
Chapter 1: Introduction
CPU Overheat LED and Control
This feature is available when the user enables the CPU overheat warning function
in the BIOS. This allows the user to defi ne an overheat temperature. When the CPU
temperature reaches the pre-defi ned overheat 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, if the system is running low
on virtual memory and there is insuffi cient hard drive space for saving the data,
you can be alerted of the potential problem. You can also confi gure Supero Doctor
to provide you with warnings when the system temperature goes beyond a predefi ned range.
1-5 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. This also includes consumer devices connected to the PC
such as VCRs, TVs, telephones and stereos.
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 Windows 2000, Windows XP and Windows
2003 Servers.
Slow Blinking LED for Suspend-State Indicator
When the CPU goes into a suspend state, the chassis power LED will start blinking
to indic ate t hat t he C PU i s in s usp e nd m od e. W he n th e us er p re s se s any key, the
CPU will wake -u p and the L ED will auto matic ally st op blink ing and r emain on.
1-11
X7DWU User's Manual
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 Standby or Off state. The external modem ring-on can
only be used with an ATX 2.01 (or above) compliant power supply.
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.
1-6 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.
The X7DCA-3/X7DCA-i can only accommodate 24-pin ATX power supply. Although
most power supplies generally meet the specifi cations required by the motherboard,
some are inadequate. You should use one that will supply at least 400W of power.
In addition, the 12V 8-pin is also required for adequate power supply to the CPU.
Also your power supply must supply 1.5A for the Ethernet ports.
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 (info
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.

Chapter 1: Introduction
1-7 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 generator ,
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). 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 supports one PC-compatible printer port (SPP), Bi-directional Printer
Port (BPP) , Enhanced Parallel Port (EPP) or Extended Capabilities Port (ECP).
The Supe r I/O provides f u n ctions that c o mply with ACPI (Advan ced Confi guration
and Power Interface), which includes suppo rt of legacy an d ACPI power manage ment through an SMI or SCI function pin. It also features auto power management
to reduce power consumpt ion.

2-1 Static-Sensitive Devices
Electrostatic-Discharge (ESD) can damage electronic com ponents. T o prevent damage 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.

2-3 Installing DIMMs
Note: Check the Supermicro web site for recommended memory modules.
Exercise extreme care when installing or removing DIMM
modules to prevent any possible damage. Also note that the
memory is interleaved to improve performance (see step 1).
DIMM Installation
Insert the desired number of DIMMs into the memory slots, starting with DIMM 1.
#1A.
The memory scheme is interleaved so 2. you must install two modules at a time,
beginning with DIMM #1A, then DIMM #2A and so on. (See the Memory Installation Table Below.)
CAUTION
Insert each DIMM module vertically into its slot. Pay attention to the notch along 3.
the bottom of the module to prevent inserting the DIMM module incorrectly.
Gently press down on the DIMM module until it snaps into place in the slot.
Repeat for all modules (see step 1 above).
Memory Support
The X7DWU supports up to 64 GB fully buffered (FBD) ECC 1.5V/1.8V DDR2
800/667/533 in 8 DIMMs. Populating DIMM modules with pairs of memory modules
of the same size and same type will result in Interleaved Memory which will
increase memory performance.

(*Notes: i. DIMM slot# specified: DIMM slot to be populated; “---“: DIMM slot not to
be populated. ii. Both FBD 800 MHz, 667 MHz and 533 MHz DIMMs are supported;
however, you need to use the memory modules of the same speed and of the same
type on a motherboard. iii. Interleaved memory is supported when pairs of DIMM
modules are installed. For optimal memory performance, please install pairs of
memory modules in both
to follow the restrictions listed above. )
