1-2 Chipset and Processor Features Overview

The Intel

X48 Express chipset, designed for use with an ntel

Xeon

3000

sequence/Core™ 2 Extreme/Core™ 2 Quad/Core™ 2 Duo processor in the LGA

775 Land Array Package, is comprised of two primary components: the Memory

Controller Hub (North Bridge) and the I/O Controller Hub (South Bridge). The

X7SBT/X7SBT - 10G provides the performance and feature-set required for the

mainstream server market.

Memory Controller Hub (X48/North Bridge)

The function of the MCH is to manage the data ﬂ 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 Intel

Xeon

3000/3200 series processor in the LGA775 Land Grid Array package. Four DIMM

slots support non-ECC Unbuffered Dual/Single Channel DDR3 1600 MHz up to

4GB in 2 DIMMs or DDR3 1333/1066/800 MHz up to 8GB in 4 DIMMs

The Ninth Generation I/O Controller Hub (ICH9R/South

Bridge)

The I/O Controller ICH9R provides the data buffering and interface arbitration re-

quired for the system to operate efﬁ 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

one PCI-Express device, four Serial ATA ports and up to six USB 2.0 portsheaders.

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

next generation of client management through the use of PROActive technology in

conjunction with Intel's next generation Gigabit Ethernet controllers.

The I/O Controller Hub provides the I/O subsystem with access to the rest of the

system. Functions and capabilities include

X7SBT/X7SBT-10G 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

Control setting in the Advanced BIOS Setup section to change this setting. The

default setting is Last State.

1-4 PC Health Monitoring

This section describes the PC health monitoring features of the X7SBT/X7SBT-

10G. All have an onboard System Hardware Monitor chip that supports PC health

monitoring.

Voltage Monitoring

An onboard voltage monitor will scan the CPU Core, Chipset, +1.5V, +3.3V, +5V,

+12V, +5V Standby and VBAT voltages continuously. Once a voltage becomes

unstable, a warning is given or an error message is sent to the screen.

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.

Chapter 1: Introduction

1-11

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 operat-

ing 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 Windows 2000, Windows XP,

Windows Vista and Windows 2003 Servers 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 a 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 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.

1-12

X7SBT/X7SBT-10G User's Manual

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 X7SBT/X7SBT-10G can only accommodate Supermicro proprietary power

supplies.

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 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 •

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.

X7SBT/X7SBT-10G User's Manual

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 ﬁ 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.

Note: Some components are very close to the mounting holes. Please take

precautionary measures to prevent damage to these components when install-

ing the motherboard to the chassis.

2-3 Processor and Heatsink Installation

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 heat-

sink.

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-

certiﬁ 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.

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.
