This manual is written for system integrators, PC technicians and  
knowledgeable PC users. It provides information for the installation and use of the  
X7DBU/X7DGU motherboard. The  
X7DBU/X7DGU supports dual  
Intel XEON 64-bit Quad-core/Dual-core processors at a front side bus speed of 1.333  
GHz/1.066 GHz/667 MHz. With dual 64-bit Xeon Quad-core/Dual-core processors,  
the 5000 chipset, and 8 DDR2 FBD 667/533 memory modules built-in, the X7DBU/  
X7DGU offers substantial functionality and performance enhancements to the moth-  
erboards based on the Core microarchitecture while remaining compatible with the  
32-bit based software. The features include Virtualization Technology, Execution  
Trace Cache, Thermal Monitor 2 (TM2), Enhanced Intel SpeedStep technology, Ad-  
vanced Dynamic Execution, Advanced Transfer Cache, Streaming SIMD Extensions

Chapter 1: Introduction  
1-2 Chipset Overview  
Built upon the functionality and the capability of the 5000P/5000X chipset, the  
X7DBU/X7DGU motherboard provides the performance and feature set required  
for dual processor-based servers with conguration options optimized for com-  
munications, presentation, storage, computation or database applications. The  
5000P/5000X chipset supports a single or dual Intel 64-bit Quad-core/Dual-core  
processor(s) with front side bus speeds of up to 1.333 GHz. The chipset consists  
of the 5000P/5000X Memory Controller Hub (MCH) and the Enterprise South Bridge  
2 (ESB2),  
The 5000P/5000X MCH chipset is designed for symmetric multiprocessing across  
two independent 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. The MCH chipset connects  
up to 8 Fully Buffered DIMM modules, providing up to 32 GB of DDR2 FBD ECC  
memory. The MCH chipset also provides three x8 PCI-Express interface to the  
ESB2. In addition, the 5000P/5000X 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 Quad-core/Dual-core Processor Features  
Designed to be used with conjunction of the 5000P/5000X chipset, the Xeon Quad-  
core/Dual-core Processor provides a feature set as follows:  
The Xeon Quad-core/Dual-core Processor  
*L1 Cache Size: Instruction Cache (32KB/16KB), Data Cache (32KB/24KB)  
*L2 Cache Size: 4MB/2MB (per core)  
*Data Bus Transfer Rate: 8.5 GB/s  
*Package: FC-LGA6/FC-LGA4, 771 Lands

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 Con-  
trol setting in the Advanced section (Boot Features) to change this setting. (Note:  
Default: Last State).  
1-4 PC Health Monitoring  
This section describes the PC health monitoring features of the X7DBU/X7DGU.  
All have an onboard System Hardware Monitor chip that supports PC health moni-  
toring.  
Onboard Voltage Monitors for CPU Cores, Memory, Chipset, HT,  
+1.8V, +3.3V, +5V, +12V, 12V, +3.3V Standby, +5V standby and  
VBAT  
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 dene 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-dened  
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.

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 insufcient hard drive space for saving the data,  
you can be alerted of the potential problem. You can also congure Supero Doctor  
to provide you with warnings when the system temperature goes beyond a pre-  
dened range.

ACPI Features  
ACPI stands for Advanced Conguration and Power Interface. The ACPI speci-  
cation denes a 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 conguration 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 Operating Systems.  
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 sus-  
pend 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 to "wake-up" the  
whole 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.

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 dened 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 trafc 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 X7DBU/X7DGU can only accommodate 20-pin ATX power supplies. Although  
most power supplies generally meet the specications required by the CPU, some  
are inadequate. The 12V 4-pin and the 12V 8-pin power connections are also re-  
quired to ensure adequate power supply to the system. In addition, the UIO power  
connector, located at J11, is required to supply power to Universal IO slots. 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 Specication 2.01 or above. It must also be SSI compliant (info at  
present, you may choose to install a line 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 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 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 provides functions that comply with ACPI (Advanced Conguration  
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.  
The IRQs, DMAs and I/O space resources of the Super I/O can exibly adjust  
to meet ISA PnP requirements, which support ACPI and APM (Advanced Power  
Management).

2-1 Static-Sensitive Devices  
Electro-Static-Discharge (ESD) can damage electronic components. To prevent  
damage to your system board, it is important to handle it very carefully. The following  
measures are generally sufcient 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 specied 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.

Mounting the Motherboard in the Chassis  
All motherboards have standard mounting holes to 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.)

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, then DIMM #2A and so on. (*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 X7DBU/X7DGU supports up to 32 GB fully buffered (FBD) ECC DDR2 667/533  
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.

(*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. For best performance, please  
install memory modules in both Branch 0 and Branch 1. iv. 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.  
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. (Refer to the Memory Availability Table on  
the next page for details.)

Fan Headers  
3-Pin Fan Header  
Pin Denitions  
The X7DBU/X7DGU has eight chassis/system  
fan headers (Fan1 to Fan8.) Fan1-Fan6 are  
chassis/system fans, while Fan7 and Fan8 are  
CPU fans. Fan5-Fan8 are 4-pin fan headers.  
Pins 1-3 of the 4-pin fan headers are backward  
compatible with the traditional 3-pin fans. The  
fan speeds for the 4-pin fans are controlled  
by Thermal Management via BIOS Hardware  
Monitor in the Advanced Setting. The default  
setting is Disabled. See the table on the right  
for pin denitions. (*Note: all these fans are  
4-pin fan connectors. However, Pins 1-3 of  
the fan headers are backward compatible with  
the traditional 3-pin fans.)

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 identied with a  
square solder pad on the printed circuit  
board. See the motherboard layout  
pages for jumper locations.

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.

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 chas-  
sis.  
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 supplies  
~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  
memory modules.  
2. Use the speaker to determine if any beep codes exist. Refer to Appendix A and  
Appendix B for details on beep codes.  
Losing the System’s Setup Conguration  
1. Make sure 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  
Section 1-6 for details on recommended power supplies.  
3-1  
Download from Www.Somanuals.com. All Manuals Search And Download.  
X7DBU/X7DGU User's Manual  
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 x the Setup Conguration 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 that 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 congured for the fastest speed of RAM used. It is recom-  
mended that you use the same RAM speed for all DIMMs in the system.  
3. Make sure that you are using the correct type of DDR2 FBD (Fully Buffered) ECC  
667/533 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 that all memory modules are fully seated in their slots. To install mem-  
ory modules, begin with Branch 1, then Branch 2, and so on (see Page 2-6).  
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 rst check with your distributor or reseller for troubleshooting  
services. They should know of any possible problem(s) with the specic system  
conguration 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 (http://  
www.supermicro.com/support/faqs/) before contacting Technical Support.  
2. BIOS upgrades can be downloaded from our web site at (http://www.supermicro.  
com/support/bios/)

3-3 Frequently Asked Questions  
Question: What are the various types of memory that my motherboard can  
support?  
Answer: The X7DBU/X7DGU has eight 240-pin DIMM slots that support DDR2  
FBD ECC 667/533 SDRAM modules. It is strongly recommended that you do not  
mix memory modules of different speeds and sizes.  
Question: How do I update my BIOS?  
Answer: It is recommended that you do not upgrade your BIOS if you are not  
experiencing any problems with your system. Updated BIOS les are located on  
warning message and the information on how to update your BIOS on our web  
site. Select your motherboard model and download the BIOS le to your computer.  
Also, check the current BIOS revision and make sure that it is newer than your  
BIOS before downloading. You can choose from the zip le and the .exe le. If you  
choose the zip BIOS le, please unzip the BIOS le onto a bootable device or a USB  
pen. Run the batch le using the format ash.bat lename.rom from your bootable  
e or USB pen to ash the BIOS. Then, your system will automatically reboot.  
If you choose the .exe le, please run the .exe le under Windows to create the  
BIOS ash oppy disk. Insert the oppy disk into the system you wish to ash the  
BIOS. Then, bootup the system to the oppy disk. The BIOS utility will automati-  
cally ash the BIOS without any prompts. Please note that this process may take  
a few minutes to complete. Do not be concerned if the screen is paused for a few  
minutes.  
(*Warning: Do not shut down or reset the system while updating BIOS to  
prevent possible system boot failure!)

Introduction  
This chapter describes the Phoenix BIOS™ Setup utility for the X7DBU/X7DGU.  
The Phoenix ROM BIOS is stored in a ash chip and can be easily upgraded using  
a 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  
changes to the BIOS that may not be reected 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. Each time  
the computer is powered on the computer is congured with the values stored in  
the CMOS Logic by the system BIOS, which gains control at boot up.  
How To Change the Conguration 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.

C-2 Conguring Supero Doctor III  
The Supero Doctor III program is a web-base 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 temperature, system voltages and fan status. See  
the Figure below for a display of the Supero Doctor III interface.  
Note 1: The default user name and password are ADMIN.  
Note 2: In the Windows OS environment, the Supero Doctor III settings take pre-  
cedence over the BIOS settings. When 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.
