Chapter 1: Introduction

1-2 Chipset Overview

Built upon the functionality and the capability of the 5000X (Greencreek) chipset,
the X7DA3+ motherboard provides the performance and feature set required for
dual processor-based workstations with confi guration options optimized for com-
munications, presentation, storage, computation or database applications. The
5000X (Greencreek) chipset supports single or dual Xeon 64-bit dual core processor
with front side bus speeds of up to 1.333 GHz. The chipset consists of the 5000X
(Greencreek) Memory Controller Hub (MCH), the Enterprise South Bridge 2 (ESB2),
and the I/O subsystem (PXH-V).

The 5000X (Greencreek) MCH chipset is designed for symmetric multiprocessing
across two independent front side bus interfaces. Each front side bus uses a 64-bit
wide, 1.333 GHz data bus that transfers data at 10.7 GB/sec. The MCH chipset con­nects up to 8 Fully Buffered DIMM modules, providing a total of 32.0 GB/s for DDR2
667/533 memory. The MCH chipset also provides one x8 PCI-Express and one x4
ESI interface to the ESB2. In addition, the 5000X (Greencreek) chipset offers a wide
range of RAS features, including memory interface ECC, x4/x8 Single Device Data
Correction, CRC, parity protection, memory mirroring and memory sparing.

Xeon Dual Core Processor Features

Designed to be used with conjunction of the 5000X (Greencreek) chipset, the Xeon
Dual Core Processors provide a feature set as follows:

The Xeon Dual Core Processors

L1 Cache Size: Instruction Cache (32KB/16KB), Data Cache (32KB/24KB)
L2 Cache Size: 2MB (per core)
Data Bus Transfer Rate: 8.5 GB/s
Package: FC-LGA6/FC-LGA4, 771 Lands

X7DA3+ 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 (Boot Features) 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 X7DA3+. All have
an onboard System Hardware Monitor chip that supports PC health monitoring.

Onboard Voltage Monitoring

An onboard voltage monitor will scan these voltages continuously: CPU Cores,
Chipset Voltage, +3.3V, +5V, +12V, -12V, +3.3V Standby, +5V Standby and Vbat.
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.

CPU Fan Auto-Off in Sleep Mode

The CPU fan activates when the power is turned on. It continues to operate when
the system enters Standby mode. When in sleep mode, the CPU will not run at full
power, thereby generating less heat.

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 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 Server.

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 "wake-up"
the system. 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.

X7DA3+ User's Manual

External Wake-On-LAN

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 X7DA3+ 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 and the 4-pin are also required for adequate power supply to the
system. 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 2.01 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.

1-7 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). 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

1-12

Chapter 1: Introduction

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 manage­ment 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. 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.

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 Motherboard Installation

(Note: Be sure to mount the motherboard into the chassis before you
install the CPU onto the motherboard.)

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.)

2-4 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 Bank

1. (For optimal memory performance, please install four modules at a time.
Please refer to the table below.)

2. Insert each DIMM module vertically into its slot. Pay attention to the notch 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 X7DA3+ supports up to 32 GB fully buffered (FBD) ECC DDR2 533/667 in 8
DIMMs. Populating DIMM modules with a pair (or pairs) of memory modules that
are of the same size and of the same type in Bank1, Bank2, Bank3 and Bank4 will
result in interleaving memory.

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