Note: This is a general block diagram. Please see the previous Motherboard Features
pages for details on the features of each motherboard.
1-8
Chapter 1: Introduction
1-2 Chipset Overview
Built upon the functionality and the capability of the 5000P chipset, the X7DB8-X/
X7DBE-X motherboard provides the performance and feature set required for dual
processor-based servers with confi guration options optimized for communications,
presentation, storage, computation or database applications. The 5000P chipset
supports single or dual Xeon 64-bit dual core processor(s) with front side bus speeds
of up to 1.333 GHz. The chipset consists of the 5000P Memory Controller Hub
(MCH), the Enterprise South Bridge 2 (ESB2), and two PXH I/O subsystems.
The 5000P 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
eight Fully Buffered DIMM modules, providing a total memory of up to 32.0 GB. 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
mirroring and memory sparing.
The Xeon Dual Core Processor Features
Designed to be used with conjunction of the 5000P chipset, the Xeon dual core
Processor provides a feature set as follows:
The Xeon Dual Core Processors
*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
1-9
X7DB8-X/X7DBE-X 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 Con-
trol setting in the Advanced BIOS Setup section to change this setting. (*Default:
Last State)
1-4 PC Health Monitoring
This section describes the PC health monitoring features of the X7DB8-X/X7DBE-
X. All have an onboard System Hardware Monitor chip that supports PC health
monitoring.
Onboard Voltage Monitors for CPU Core, HT Voltage, Memory
Voltage, Chipset Voltage, +1.8V, +3.3V, +5V, +12V, −12V, +3.3V
Standby, +5V Standby and VBATT.
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
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.
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.
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
X7DB8-X/X7DBE-X 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 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 X7DB8-X/X7DBE-X can only accommodate 24-pin ATX power supplies. Al-
though 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 also required to support
Intel 64-bit CPUs. 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.

2-3 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 (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. (*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 X7DB8-X/X7DBE-X supports up to 16 GB (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.
*Note 1: Due to OS limitations, some operating systems may not show more than
(*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
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
