1-4 Chipset Overview

The Intel

X48 Express chipset, designed for use with an Intel

Xeon

3000 se-

quence/Core

2 Extreme/Core

2 Quad/Core

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

2 Extreme/Core

2 Quad/Core

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

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

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.
