Chapter 1: Introduction

1-2 Chipset and Processor Features Overview

Built upon the functionality and the capability of the Intel 5100 chipset, the X7DCL-

3/X7DCL-i motherboard provides the performance and feature set required for

dual processor-based high-end servers 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 Series processors with front side bus speeds of up to 1.333

GHz. 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,

1066/1333 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 six DDR2 667 MHz/533 MHz DIMM modules, providing a total memory capac-

ity of up to 32 GB.

The 5100 MCH also provides six x4 PCI-Express interfaces and one x4 DMI

Interface to the ICH9R. Each PCI Express port on the MCH provides 4 GB/s bi-

directional 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 (ICH9)

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 six PCI-Express x1 slots, six Serial ATA ports and twelve 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.

X7DCL-3/X7DCL-i User's Manual

1-3 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 Power Lost Control

setting in the Advanced BIOS Setup section to change this setting. The default

setting is Last State.

1-4 PC Health Monitoring

This section describes the PC health monitoring features of the X7DCL-3/X7DCL-

i. All have an onboard System Hardware Monitor chip that supports PC health

monitoring.

Onboard Voltage Monitors

An onboard voltage monitor will scan for the 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 chas-

sis temperature is too high.

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.

1-10

Chapter 1: Introduction

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 pre-defi ned range.

1-5 ACPI Features

ACPI stands for Advanced Confi guration and Power Interface. The ACPI specifi -

cation 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 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.

1-11

X7DCL-3/X7DCL-i User's Manual

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. Note that 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 X7DCL-3/X7DCL-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.

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 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

1-12

Chapter 1: Introduction

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 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

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 fol-

lowing 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.

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

Note: Check the SuperMicro web site for recommended memory modules.

CAUTION

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

1. Insert the desired number of DIMMs into the memory slots, starting with 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. (See the Memory Installation Table Below.)

2. Insert each DIM M mo d ule ver tically into i t s slot. Pay attention to t he n otch along

the bottom of the module to prevent inserting the DIMM module incorrectly.

3. 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 X7DCL-3/X7DCL-i supports up to 32 GB Single-Rank, Registered ECC DDR2

667/533 in 6 DIMMs. Populating DIMM modules with pairs of memory modules

of the same size and same type will result in Interleaved Memory which will

improve memory performance.

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

4 GB of memory.

(Notes: i. DIMM slot# specified: DIMM slot to be populated; “---“: DIMM slot not to be
populated. ii. Both Registered ECC DDR2 667MHz 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. For memory to work properly, you need to follow the restrictions listed
above. )
