Chapter 1: Introduction

1-2 Chipset and Processor Features Overview

Built upon the functionality and the capability of the Intel 5100 chipset, the
X7DCX 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 three x8 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 one PCI-Express x16 slot, 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.

1-4 PC Health Monitoring

This section describes the PC health monitoring features of the X7DCX. 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 exible and ab st rac t ha rd ware i nterfac e t hat p rovi de s 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 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.

X7DCX 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 X7DCX 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, depend­ing on your system confi guration. 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.

1-12

Chapter 1: Introduction

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 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 e-

2-4 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 1B, then DIMM 2A, DIMM 2B,
and DIMM 3A, DIMM 3B.

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 X7DCX 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 ------ ------ DIMM1B ------ -----­4DIMMs DIMM1A DIMM2A ------ DIMM1B DIMM2B -----­6DIMMs DIMM1A DIMM2A DIMM3A DIMM2A DIMM2B DIMM3B

(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. )

Note 1: Due to OS limitations, some operating systems may not show
more than 4 GB of memory.

Optimized DIMM Population Configurations

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

Fan Headers

The X7DCX has six chassis/system fan
headers (Fans 1~Fan 6), and two CPU
fan headers (Fans 7~8). These fan head­ers support 4-pin or 3-pin fans. However,
for the system to function properly, please
use all 3-pin or all 4-pin fans on a moth­erboard. See the table on the right for pin
defi nitions.

Note: The speeds of 4-pin (PWM) fans
are controlled by Thermal Management
via BIOS Hardware Monitoring in the
Advanced Setting. (The default setting
is Disabled.)

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.

Watch Dog Enable/Disable

Watch Dog (JWD1) is a system moni­tor that can reboot the system when a
software application hangs. Close pins
1-2 to reset the system if an applica­tion ha ngs. Close pi ns 2-3 to gener ate a

Chapter 4

BIOS

4-1 Introduction

This chapter describes the Phoenix BIOS™ Setup utility for the X7DCX. 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 our web site at <http://www.supermicro.com> for any changes to
the BIOS that may not be refl ected in this manual.

System BIOS

BIOS is the Basic Input Output System used in all IBM® PC, XT™, AT®, and PS/2®
compatible computers. The Phoenix BIOS utility 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.

How To Change the Confi guration Data

The CMOS 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.)

Starting the Setup Utility

Normally , the only visible POST (Power On Self Test) routine is the memory test. As
the memory is being tested, press the <Delete> key to enter the main menu of the
BIOS Setup utility. From the main menu, you can access the other setup screens,
such as the Security and Power menus. Beginning with Section 4-3, detailed de­scriptions are given for each parameter setting in the Setup utility.

Warning: Do not shut down or reset the system while updating BIOS

to prevent possible boot failure.
