®
X48 Express chipset, designed for use with an Intel
®
Xeon
®
3000 se-
quence/Core
TM
2 Extreme/Core
TM
2 Quad/Core
TM
2 Duo processor in the LGA 775
Land Grid Array Package, is comprised of two primary components: the Memory
Controller Hub (MCH) and the I/O Controller Hub (ICH9R). The X7SBU provides
the performance and feature-set required for the mainstream server market.
Note: The Intel
®
X48 chipset does not support add-in graphics cards in the
PCI-E interface by the Memory Controller Hub
Memory Controller Hub (X48)
The function of the MCH is to manage the data ow between four interfaces: the
CPU interface, the DDR3 System Memory interface, the PCI Express interface,
and the Direct Media Interface (DMI). The MCH is optimized for the Xeon
®
3000
sequence/Core
TM
2 Extreme/Core
TM
2 Quad/Core
TM
2 Duo processor in the LGA775
Land Grid Array package.and supports up to 8 Gb Unbuffered DDR3 Non-ECC up
to 1333 MHz in 4 DIMMs or DDR3 Non-ECC 1600 MHz up to 4GB in 2 DIMMs
memory
I/O Controller (ICH9R)
The I/O Controller (ICH9R) provides the data buffering and interface arbitration
required for the system to operate ef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 two
PCI-Express devices, six Serial ATA ports, and up to seven USB 2.0 ports/headers.
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 controller.

1-5 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 section to change this setting.
1-6 PC Health Monitoring
This section describes the PC health monitoring features of the X7SBU. All have an
onboard System Hardware Monitor chip that supports PC health monitoring.
An onboard voltage monitor will scan the Onboard Voltage Monitors for the CPU
Cores, Memory Voltage, +1.8V, +3.3V, +5V, +5V Standby, +12V, 12V and Vbatt.(via
SuperO Doctor) 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 de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-de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.
With the Intel
®
ICH9R built in, the X7SBU supports I/O Virtualization Technology
(VT-d) that enables multiple operating systems and applications to run in inde-
pendent partitions. Each partition uses its own subset of host physical memory,
and behaves like a virtual machine (VM), providing isolation and protection across

With the Intel
®
ICH9R built in, the X7SBU supports I/O Virtualization Technology
(VT-d) that enables multiple operating systems and applications to run in inde-
pendent partitions. Each partition uses its own subset of host physical memory,
and behaves like a virtual machine (VM), providing isolation and protection across
multiple partitions. This feature is available when a processor that supports I/O
Virtualization Technology is installed on the motherboard.
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 de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 insufcient hard drive space for saving the data,
you can be alerted of the potential problem. You can also congure Supero Doctor
to provide you with warnings when the system temperature goes beyond a pre-
dened range.
1-7 ACPI Features
ACPI stands for Advanced Conguration and Power Interface. The ACPI specica-
tion denes 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 con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 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.
1-8 Super I/O
The disk drive adapter functions of the Super I/O chip include 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 Super I/O supports
two 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 sys-
tem. 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 the ACPI (Advanced Congura-
tion and Power Interface), which includes support of legacy and ACPI power man-
agement through a SMI or SCI function pin. It also features auto power management
to reduce power consumption.

Installation
2-1 Static-Sensitive Devices
Electrostatic-Discharge (ESD) can damage electronic com ponents. To prevent dam-
age to your system board, it is important to handle it very carefully. The following
measures are generally suf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 speci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.
X7SBU User's Manual
2-2
Warning: 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 LGA 775 socket before you install the CPU
heatsink.
2. The Intel
®
LGA 775 Processor package contains the CPU fan and heatsink
assembly. If you buy a CPU separately, make sure that you use only Intel-
certied multi-directional 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 775 Processor or when receiving a motherboard
with an LGA 775 Processor 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.
2-3 Processor and Heatsink Installation
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 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..
Please note that some components are very close to the mounting holes.
Please take precautionary measures to prevent damage to these components
when installing the motherboard to the chassis
Caution: To avoid damaging the motherboard and its components, please do
not use a force greater than 8 lb/inch on each mounting screw during moth-
erboard installation.
