Chapter 1: Introduction

1-2 Chipset Overview

Built upon the functionality and the capability of the 5000P chipset, the X7DB3

motherboard provides the performance and feature set required for dual pro-

cessor-based servers with conﬁ guration options optimized for communications,

presentation, storage, computation and database applications. The 5000P chipset

supports single or dual 64-bit quad core/dual core processor(s) with front side bus

speeds of up to 1.333 GHz/1.066 GHz/677 MHz. The chipset consists of the 5000P

Memory Controller Hub (MCH), the Enterprise South Bridge 2 (ESB2), and the I/O

subsystem (PXH).

The 5000P MCH chipset is designed for symmetric multiprocessing across two inde-

pendent front side bus interfaces. Each front side bus uses a 64-bit wide, 1333 MHz

data bus that transfers data at 10.7 GB/sec. (for a total bandwidth of 21.3GB/sec.).

The MCH chipset connects up to eight Fully Buffered DIMM modules, providing

a total memory bandwidth of 32 GB/s for DDR2 533/667. The MCH chipset also

provides one x8 PCI-Express and one x4 ESI interfaces to the ESB2. In addition,

the 5000P chipset offers a wide range of RAS features, including memory interface

ECC, x4/x8 Single Device Data Correction, CRC, parity protection, memory mirror-

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 power-on state, or you can also choose for

it to automatically return to the last state prior to power loss. See the Power Lost

Control setting in the Advanced BIOS Setup section (Boot Features) to change

this setting.

1-4 PC Health Monitoring

This section describes the PC health monitoring features of the X7DB3. All have an

onboard System Hardware Monitor chip that supports PC health monitoring.

Onboard Voltage Monitors for +1.5V,+1.8V, +3.3V, +5V, +12V, −12V, +3.3V Standby, and +5V standby

An onboard voltage monitor will scan these 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 the

Hardware Monitoring section in the Advanced BIOS Setup section.)

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.

1-10

Chapter 1: Introduction

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.

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 this tem-

perature is exceeded, 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 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 both Windows 2000 and Windows NT 5.0.

This setting is also located in the Advanced BIOS Setup section (Boot Features).

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.

1-11

X7DB3 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 Boot section of the

Advanced 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 SoftOff state. Note that external modem ring-on can only

be used with an ATX 2.01 (or above) compliant power supply.

Wake-On-LAN (WOL)

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 X7DB3 can only accommodate 24-pin ATX power supplies. Although most

power supplies generally meet the speciﬁ cations required by the CPU, some are

inadequate. In addition, the 12V 4-pin power supply - is also required to ensure

adequate power supply to the system. Also your power supply must supply 1.5A

for the Ethernet ports.

1-12

Chapter 1: Introduction

NOTE: The + 12V 8-pin Aux. Power Connector is always required. Failure to

provide this extra power will result in CPU PWR Failure. See Section 2-5 for

details on connecting the power supply.

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

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 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

Electric-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 manu-

facturer. Do not install the onboard battery upside down to avoid possible explo-

sion.

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 Processor and Heatsink Fan Installation

When handling the processor package, avoid placing

direct pressure on the label area of the fan.

(*Notes: 1. Always connect the power cord last and always remove it before adding,

removing or changing any hardware components. Make sure that you install the

processor into the CPU socket before you install the CPU heatsink.

2. Intel's boxed Xeon CPU package contains the CPU fan and heatsink assembly.

If you buy a CPU separately, make sure that you use only Intel-certiﬁ ed multi-di-

rectional heatsink and fan.

3. Make sure to install the motherboard into the chassis before you install the CPU

heatsink and fan.)

4. When purchasing an LGA 771 CPU or when receiving a motherboard with an LGA

771 CPU pre-installed, make sure that the CPU plastic cap is in place and none of

the CPU pins are bent; otherwise, contact the retailer immediately.

5. Refer to the MB Features Section for more details on CPU support.

Chapter 2: Installation

Mounting the Motherboard in the Chassis

All motherboards have standard mounting holes to ﬁ t different types of chas-

sis. 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 to the chassis.)

X7DB3 User's Manual

2-3 Installing DIMMs

Note: Check the Super Micro 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 (See Figure 2-2)

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, then DIMM #2A and so on. (Please see the

Memory Installation 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 X7DB3 supports up to 32 GB fully buffered (FBD) ECC DDR2 533/667 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.

*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 FBD 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. Interleaved memory is supported when pairs of DIMM modules are installed. To optimize memory performance, please install pairs of DIMMs in both Branch 0 and Branch 1. iv. For memory to work properly, you need to follow the restrictions listed above. )

*Note 2: Due to memory allocation to system devices, memory remaining avail-

able for operational use will be reduced when 4 GB of RAM is used. The reduction

in memory availability is disproportional. (Refer to the following Memory Availability

Table for details.)

ATX Power Connector

There are a 24-pin main power sup-

ply connector(JPW1) and an 8-pin

CPU PWR connector (JPW3) on the

motherboard. These power connec-

tors meet the SSI EPS 12V speciﬁ ca-

tion. The 4-pin 12V PWR supply is

required to provide adequate power

to the system. See the table on the

right for pin deﬁ nitions. For the 8-pin

PWR (JPW3), please refer to the item

listed below.

Processor Power Connector

In addition to the Primary ATX power

connector (above), the 12V 8-pin CPU

PWR connector at JPW3 must also

be connected to your power supply.

X7DB3 User's Manual

Fan Headers

The X7DB3 has six chassis/system fan head-

ers (Fan1 to Fan6) and two CPU Fans (Fan7

and Fan8). (*Note: Fans#1-4 are 3-pin fans.

Fans#5-8 are 4-pin fans. However, Pins 1-3

of the fan headers are backward compatible

with the traditional 3-pin fans.) See the table on

the right for pin deﬁ nitions. (*The onboard fan

speeds are controlled by Thermal Management

under Hardware Monitoring in the Advanced

Setting in the BIOS

. Note: Default: Disabled,

When using Thermal Management setting,

please use all 3-pin fans or all 4-pin fans on

the motherboard.)

Keylock

The keyboard lock connection is designated

JK1. Utilizing this header allows you to inhibit

any actions made on the keyboard, effectively

"locking" it.

2-6 Jumper Settings

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.

GLAN Port1/GLAN Port2 on the moth-

erboard. See the table on the right for

jumper settings. The default setting

Chapter 2: Installation

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 clear-

ing 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 is a system monitor that can reboot

the system when a software application hangs.

Close pins 1-2 to reset the system if an applica-

tion hangs. Close pins 2-3 to generate a non-

maskable interrupt signal for the application that

hangs. See the table on the right for jumper set-

tings. Watch Dog must also be enabled in the

BIOS.

2-7 Onboard Indicators

GLAN LEDs

There are two GLAN ports on the moth-

erboard. Each Gigabit Ethernet LAN port

has two LEDs. The yellow LED indicates

activity, while the power LED may be

green, orange or off to indicate the speed

of the connection. See the tables at right

for more information.

Onboard Power LED

There is an Onboard Power LED (LE1)

located on the motherboard. When LE1 is

off, the system is off. When the green light

is on, the system is on. When the yellow

light is on, the system is off, but the AC

power cable is still connected. Make sure

to disconnect the power cable before re-

moving or installing components. See the

layout below for the LED location.

2-8 Parallel Port, Floppy Drive, Hard Disk Drive and SIMLP IPMI Connections

Note the following when connecting the ﬂ oppy and hard disk drive cables:

• The ﬂ oppy disk drive cable has seven twisted wires.

• A red mark on a wire typically designates the location of pin 1.

• A single ﬂ oppy disk drive ribbon cable has 34 wires and two connectors to provide

for two ﬂ oppy disk drives. The connector with twisted wires always connects to

drive A, and the connector that does not have twisted wires always connects to

drive B.

Parallel (Printer) Port Connector

The parallel (printer) port is located

at J21. See the table on the right for

pin deﬁ nitions.

Troubleshooting

3-1 Troubleshooting Procedures

Use the following procedures to troubleshoot your system. If you have followed all

of the procedures below and still need assistance, refer to the ‘Technical Support

Procedures’ and/or ‘Returning Merchandise for Service’ section(s) in this chapter.

Note: Always disconnect the power cord before adding, changing or installing

any hardware components.

Before Power On

1. Make sure that there are no short circuits between the motherboard and chas-

sis.

2. Disconnect all ribbon/wire cables from the motherboard, including those for the

keyboard and mouse.

3. Remove all add-on cards.

4. Install one CPU (making sure it is fully seated) and connect the chassis speaker

and the power LED to the motherboard. (Check all jumper settings as well.)

5. Use only the correct type of CMOS onboard battery as recommended by the

Manufacturer. Do not install the onboard battery upside down to avoid pos-

sible explosion.

No Power

1. Make sure that there are no short circuits between the motherboard and the

chassis.

2. Verify that all jumpers are set to their default positions.

3. Check that the 115V/230V switch on the power supply is properly set.

4. Turn the power switch on and off to test the system.

5. The battery on your motherboard may be old. Check to verify that it still sup-

plies ~3VDC. If it does not, replace it with a new one.

No Video

1. If the power is on but you have no video, remove all the add-on cards and

cables.

2. Use the speaker to determine if any beep codes exist. Refer to the Appendix

for details on beep codes.

Losing the System’s Setup Conﬁ guration

1. Ensure that you are using a high quality power supply. A poor quality power

supply may cause the system to lose the CMOS setup information. Refer to

3-1

X7DB3 User's Manual

Section 1-6 for details on recommended power supplies.

2. The battery on your motherboard may be old. Check to verify that it still supplies

~3VDC. If it does not, replace it with a new one.

3. If the above steps do not ﬁ x the Setup Conﬁ guration problem, contact your

vendor for repairs.

NOTE

If you are a system integrator, VAR or OEM, a POST diagnostics

card is recommended. For I/O port 80h codes, refer to App. B.

Memory Errors

1. Make sure the DIMM modules are properly and fully installed.

2. Determine if different speeds of DIMMs have been installed and verify that the

BIOS setup is conﬁ gured for the fastest speed of RAM used. It is recom-

mended to use the same RAM speed for all DIMMs in the system.

3. Make sure you are using the correct type of DDR2 Fully Buffered (FBD) ECC

533/667 SDRAM (*recommended by the manufacturer.)

4. Check for bad DIMM modules or slots by swapping a single module between

four slots and noting the results.

5. Make sure all memory modules are fully seated in their slots. As an interleaved

memory scheme is used, you must install two modules at a time, beginning

with Bank 1, then Bank 2, and so on (see Section 2-3).

6. Check the position of the 115V/230V switch on the power supply.

3-2 Technical Support Procedures

Before contacting Technical Support, please take the following steps. Also, note

that as a motherboard manufacturer, Super Micro does not sell directly to end-us-

ers, so it is best to ﬁ rst check with your distributor or reseller for troubleshooting

services. They should know of any possible problem(s) with the speciﬁ c system

conﬁ guration that was sold to you.

1. Please go through the ‘Troubleshooting Procedures’ and 'Frequently Asked Ques-

tion' (FAQ) sections in this chapter or see the FAQs on our web site (

www.supermicro.com/support/faqs/

2. BIOS upgrades can be downloaded from our web site at

com/support/bios/

Note: Not all BIOS can be ﬂ ashed; it depends on the modiﬁ cations to the

boot block code.

)

) before contacting Technical Support.

(http://www.supermicro.

3-2

http://

Chapter 3: Troubleshooting

3. If you still cannot resolve the problem, include the following information when

contacting Super Micro for technical support:

• Motherboard model and PCB revision number

• BIOS release date/version (this can be seen on the initial display when your

system ﬁ rst boots up)

•System conﬁ guration

An example of a Technical Support form is on our web site at

supermicro.com/support/contact.cfm).

3-3 Frequently Asked Questions

Question: What are the various types of memory that my motherboard can

support?

Answer: The X7DB3 has eight 240-pin DIMM slots that support DDR2 FDB ECC

533/667 SDRAM modules. It is strongly recommended that you do not mix memory

modules of different speeds and sizes. (See Chapter 2 for detailed Information.)

Question: How do I update my BIOS?

Answer: It is recommended that you do not upgrade your BIOS if you are experi-

encing no problems with your system. Updated BIOS ﬁ les are located on our web

site at

message and the info on how to update your BIOS on our web site. Also, check the

current BIOS revision and make sure it is newer than your BIOS before downloading.

Chapter 4 BIOS

4-1 Introduction

This chapter describes the Phoenix BIOS™ Setup utility for the X7DB3. 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 Super Micro 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 pro-

vides power to the CMOS Logic, enabling it to retain system parameters. When 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 de-

scriptions 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.

The following items will be monitored and displayed:

P12V_VR0/P12V_VR1/FSB VTT/PXH Vcore/ES2B Vcore/CPU1Vcore/CPU2Vcore/ P3V3

*Note: In the Windows OS environment, the Supero Doctor III settings take pre-

cedence 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.
