Chapter 1: Introduction

1-2 Chipset and Processor Features Overview

Built upon the functionality and the capability of the Intel 5100 chipset, the
X7DCU motherboard provides the performance and feature set required for dual
processor-based high-end computer systems with confi guration options optimized
for intensive computing, high energy-effi ciency and complex business applications.
The 5100 chipset supports single or dual Intel Xeon 64-bit Quad-Core/Dual-Core
5400/5300/5200/5100 Sequence processors with front side bus speeds of up to
1333 MHz. The chipset consists of the 5100 Memory Controller Hub (MCH), Intel
I/O Controller Hub (ICH9R) and the I/O subsystem.

The 5100 Memory Controller Hub (MCH)

The Intel 5100 MCH chip is designed for symmetric multiprocessing across two
independent front side bus interfaces. Each front side bus uses a 64-bit wide,
1333/1066 MTS data bus capable of transferring data at 8.5/10.6 GB/s for a total
bandwidth of 17/21.3 GB/s. The MCH supports a 36-bit wide address bus and up
to four DDR2 667 MHz/533 MHz DIMM modules, providing a total memory capacity
of up to 48 GB.

The 5100 MCH also provides two x4 PCI-Express interfaces and one x4 DMI
Interface to the ICH9R. Each PCI Express port on the MCH provides 4 GB/s bi­directional bandwidth if confi gured as a x8 port, or 2 GB/s bi-directional bandwidth
if confi gured as a x4 port.

The Ninth Generation I/O Controller Hub (ICH9R)

The I/O Controller ICH9R provides the data buffering and interface arbitration re­quired for the system to operate effi ciently. It also provides the bandwidth needed
for the system to maintain its peak performance. The Direct Media Interface (DMI)
provides the connection between the MCH and the ICH9R. The ICH9R supports
up to two PCI-Express x8 or x16 slots, six Serial ATA ports and six USB 2.0 ports.
In addition, the ICH9R offers the Intel Matrix Storage Technology which provides
various RAID options for data protection and rapid data access. It also supports the
next generation of client management through the use of PROActive technology in
conjunction with Intel's next generation Gigabit Ethernet controllers.

default set tin g is Last State.

1-4 PC Health Monitoring

This section describes the PC health monitoring features of the X7DCU. All have an
onboard System Hardware Monitor chip that supports PC health monitoring.

Voltage Monitoring

An onboard voltage monitor will scan the CPU Core, Chipset, +1.8V, +3.3V, +5V,
+12V, -12V, +3.3V Standby, +5V Standby and VBAT voltages 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
notif y the user of cer tain system events. For example, if the system is running
low on vir tual memor y and there is insuffi cient hard drive space for saving the
data, you c an be a lerted of t he pote ntia l pro ble m. You can also c onfi gure Supero
Docto r to provide yo u with warn ings when t he system tempe rature goe s beyond
a pre- de fi ned range.

1-5 ACPI Features

ACPI stands for Advanced Confi guration and Power I nter face. T he ACPI spe cifi -
cation defi nes a fl exi bl e and a bst ra ct h ard war e interfac e t hat p rov id es a st an dar d
way to integrate powe r manage ment featur es throu ghout a PC sys tem, inclu ding
its hardware, operating system and application software. This enables the system
to automat ically turn o n and off peri pherals such as C D-RO Ms, network c ards,
hard disk dr ives and p rinter s. This al so incl udes co nsumer d evices c onne cted to
the PC suc h as VCRs, T Vs, teleph ones and s tereos.

In addition to enabling operating system-directed power management, ACPI
provid es a gener ic system eve nt mecha nism for Pl ug and Play an d an oper ating
system-independent interface for confi guration control. ACPI leverages the Plug
and Play BIO S dat a str uc ture s whi le pr ovid ing a pr oc es sor a rch itec tur e- in dep en ­dent implementation that is compatible with Windows 2000, Windows XP and
Windows 2003 Ser vers.

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

X7DCU 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 X7DCU can only accommodate 20-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 Supe r I/O provides fun ction s that com ply with AC PI (A d va n ced Confi guration
and Power Interfa ce), which incl u d e s su p por t o f l e g a c y and ACPI power ma n a g e­ment through an SMI or SCI function pin. It also features auto power management
to reduce power consumpt ion.

2-1 Static-Sensitive Devices

Electro-Static-Discharge (ESD) can damage electronic com ponents. To 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 antist atic packag i n g t o avo id static da mage. When
unpacking the board, make sure the person handling it is static protected.

Mounting the Motherboard in the Chassis

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. 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 done to these components when
you install the motherboard into the chassis.

2-3 Installing DIMMs

Exercise extreme care when installing or removing DIMM

module s to prevent any po ssib le damag e. Also n ote that th e

memor y is i nterl eaved to imp rove per fo rman ce..

DIMM Installation

Insert the desired number of DIMMs into the memory slots, starting with 1.
DIMM #1A. The memory scheme is interleaved, so you must install two mod­ules at a time, beginning with DIMM 1A, DIMM 2A, then DIMM 1B, DIMM 2B,
and DIMM 1C, DIMM 2C.

Insert each DIMM module vertically into its slot. Gently press down on the 2.
DIMM module until it snaps into place in the slot. Repeat for all modules. Pay
attention to the notch along the bottom of the module to prevent inserting the
DIMM module incorrectly.

CAUTION

This motherboard supports both dual-rank and single-rank memory modules. 3.
For system memory to work properly, please use all dual-rank memory mod­ules or use all single-rank memory modules on the same motherboard. Check
the Supermicro web site for other information.

Memory Support

The X7DCU supports up to 48 GB Buffered (Registered) ECC DDR2 667/533
MHz in 6 DIMMs. Populating memory slots of the same bank with a pair (or pairs)
of memory modules of the same size and same type will result in two-way Inter-

leaved Memory which will improve memory performance. (See the table below.)

No. of

DIMMs

2DIMMs DIMM1A ------ ------ DIMM2A ------ -----­4DIMMs DIMM1A DIMM1B ------ DIMM2A DIMM2B -----­6DIMMs DIMM1A DIMM1B DIMM1C DIMM2A DIMM2B DIMM2C

(Notes: i. DIMM slot# specified: DIMM slot to be populated; “---“: DIMM slot not to be
populated. ii. Both 533 MHz and 667MHz DIMMs are supported; however, you need to use
the memory modules of the same speed and of the same type on a motherboard. iii. For
memory to work properly, you need to follow the restrictions listed above. )

Optimized DIMM Population Configurations

Channel 0 Channel 1

Note 1: Due to OS limitations, some operating systems may not show

more than 4 GB of memory.
Note 2: Due to memory allocation to system devices, memory remaining

available for operational use will be reduced when 4 GB of RAM is used.
The reduction in memory availability is disproportional. (See the following
table for details.)

Keylock

The keyboard lock connection is desig­nated JK1. Utilizing this header allows
you to inhibit any actions made on the
keyboard, effectively "locking" it.

Unit Identifi cation Switches

There are two Unit Identifi cation (UID)
switches on the motherboard. The Front
Panel UID switch is connected to Pin 13
of the Front Control Panel. The Rear
UID switch (SW1) is located next to LAN
Port2. When you push the UID switch on
the Front Control Panel, you will turn on
both the Rear and the Front Panel UID
indicator. Press the Front Panel or the
Rear UID switch again to turn off the UID
Indicators. The UID LED (LE2) works in
conjunction with the UID switches. Press
the UID switches to turn on and off the
UID LED Indicators. The UID Switches
and the UID LED Indicators provide easy
identifi cation of a system unit that may be
in need of service. (For more information
on the FP UID Switch, please refer to

Explanation of Jumpers

To modify the operation of the mother­board, 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 identifi 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.

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 clearing CMOS. Note:
For an ATX power supply, you must completely shut down the system, remove the
AC power cord and then short JBT1 to clear CMOS.

Chapter 4

BIOS

4-1 Introduction

This chapter describes the Phoenix BIOS™ Setup utility for the X7DCU. The
Phoenix ROM BIOS is stored in a fl ash chip and can be easily upgraded using a
fl oppy disk-based program.

Note: Due to periodic changes to the BIOS, some settings may have been
added or deleted and might not yet be recorded in this manual. Please
refer to the Manual Download area of the Supermicro web site <http://www.
supermicro.com> for any changes to the BIOS that may not be refl ected
in this manual.

System BIOS

The BIOS is the Basic Input Output System used in all IBM® PC, XT™, AT®, and

®

PS/2

compatible computers. The Phoenix BIOS stores the system parameters,
types of disk drives, video displays, etc. in the CMOS. The CMOS memory requires
very little electrical power. When the computer is turned off, a backup battery pro­vides power to the CMOS Logic, enabling it to retain system parameters. Each time
the computer is powered on, the computer is confi gured with the values stored in
the CMOS Logic by the system BIOS, which gains control at boot up.
information that determines the system parameters may be changed by entering
the BIOS Setup utility. This Setup utility can be accessed by pressing the <Delete>
key at the appropriate time during system boot. (See below.)

The CMOS

Starting the Setup Utility

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 temperatures, system voltages and fan status.
See the Figure below for a display of the Supero Doctor III interface.

Note 1: Both default username and password are ADMIN.
Note 2: In the Windows OS environment, the Supero Doctor III settings

take precedence over the BIOS settings. When fi rst installed, Supero
Doctor III adopts the temperature threshold settings previously set in the
BIOS. Any subsequent changes to these thresholds must be made within
Supero Doctor, since the SD III settings override the BIOS settings. For
the Windows OS to adopt the BIOS temperature threshold settings, please
change the SDIII settings to be the same as those set in the BIOS.
