1-2 Chipset and Processor Features Overview

The Intel® X48 Express chipset, designed for use with an ntel® Xeon® 3000
sequen ce/Co re™ 2 Extreme /Core™ 2 Quad/C ore™ 2 Duo proces sor 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 fun cti on of the M CH is t o manag e the dat a fl ow between four inte r fac es: the
CPU inter face, th e DDR3 System M emor y Interfa ce, the PCI E xpress Inte rfac e,
and the Di r e ct Media Inte rface (DMI). The M CH is optimi ze d f o r t h e I nte l® Xeon®
3000/32 00 series processor in the LGA775 Land G rid Array package. Fo ur DIMM
slots sup port non -ECC Unbu ffered D ual/Singl e Channel DDR3 16 00 MHz up to
4GB in 2 DI MM s or DDR3 133 3/1066 /80 0 MHz u p to 8GB i n 4 DIM Ms

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

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

1-4 PC Health Monitoring

This section describes the PC health monitoring features of the X7SBT/X7SBT­10G. 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 chas­sis temperature is too high.

1-10

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
notif y the user of cer tain system events. For example, if the system is running
low on vir tual memor y and there is insuffi c ient hard drive space for saving the
data, you c an be a lerted of th e potent ial p rob lem. You can als o co nfi gure Supero
Docto r to provide yo u with warn ings when t he system tempe rature goe s beyond
a pre- de fi ned range.

1-5 ACPI Features

ACPI stands for Advanced Confi guration and Power I nter face. T he ACPI spe cifi -
cation defi nes a fl exible and abstr ac t har dwa re inte rface t hat p rov id es a st an dar d
way to integrate powe r manage ment featur es throu ghout a PC sys tem, inclu ding
its hardware, operating system and a pplicat ion sof tware. This enables the system
to automat ically turn o n and off peri pherals such as C D-RO Ms, network c ards,
hard disk dr ives and p rinter s. This al so incl udes co nsumer d evices c onne cted to
the PC suc h as VCRs, T Vs, teleph ones and s tereos.

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 architecture­indepe n d en t im p l e m e ntation t hat i s compati b l e w i t h W i n d o ws 2 000, W i n d ow s XP,
Window s Vist a and Win dows 20 03 Se rve rs ope rating sy stems.

Slow Blinking LED for Suspend-State Indicator

When the CPU goes into a suspend state, the chassis power LED will start blinking
to indic ate t hat t he C PU i s in s usp e nd m od e. W he n th e us er p re s se s any key, the
CPU will wake -u p and the L ED will auto matic ally st op blink ing and r emain 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.

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 i s s h i pped in antistatic packa g i n g t o avo id static damage. When
unpacking the board, make sure the person handling it is static protected.

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 install­ing 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 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 Intel­certifi 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.

Installing the LGA 775 Processor

1. Press the load lever to release the
load plate, which covers the CPU
socket, from its locking position.

2. Gently lift the load lever to open the
load plate.

3. Use your thumb and your index fi n-
ger to hold the CPU at the top center
edge and the bottom center edge of
the CPU.

4. Align CPU Pin1 (the CPU corner
marked with a triangle) against the
socket corner that is marked with a
triangle cutout.

5. Align the CPU key that is the
semi-circle cutout below a golden dot
against the socket key, the Notch on
the same side of the triangle cutout on
the socket.

6. Once aligned, carefully lower the
CPU straight down to the socket.
(Do not drop the CPU on the socket.
Do not move the CPU horizontally or
vertically. Do not rub the CPU against
the surface or against any pins of the
socket to avoid damage to the CPU or
the socket.)

7. With the CPU inside the socket,
inspect the four corners of the CPU
to make sure that the CPU is properly
installed.

8. Use your thumb to gently push the
load lever down to the lever lock.

9. If the CPU is properly installed into
the socket, the plastic PnP cap will be
automatically released from the load
plate when the load lever is pushed in
the lever lock. Remove the PnP cap
from the motherboard.

Warning: Please save the plastic
PnP cap. The motherboard must be
shipped with the PnP cap properly
installed to protect the CPU socket
pins. Shipment without the PnP cap
properly installed will cause dam­age to the socket pins.

Installing the Heatsink

1. Do not apply any thermal grease to
the heatsink or the CPU die, the required
amount has already been applied.

2. Place the heatsink on top of the
CPU so that the four mounting holes
are aligned with those on the retention
mechanism.

Chapter 2: Installation

3. Screw in two diagonal screws (eg. the
#1 and the #2 screws) until just snug (do
not fully tighten the screws, which may
damage the CPU).

4. Finish the installation by fully tighten­ing all four screws.

Removing the Heatsink

Warning: We do not recommend that the CPU or the heatsink be removed.
However, if you do need to uninstall the heatsink, please follow these instruc­tions below to prevent damage to the CPU or the CPU socket.

1. Unscrew and remove the heatsink screws
from in the sequence as show in the picture
on the right.

2. Hold and gently wriggle the heatsink to
loosen it from the CPU. (Do not use excessive
force when loosening the heatsink!)

3. Once the heatsink is loosened, remove it
from the CPU socket.

4. Clean the surfaces of the CPU and the
heatsink to remove the old thermal grease.
Reapply the proper amount of thermal

grease on the surface before re-installing the
CPU and the heatsink.

2-4 Installing DIMMs

Note: Check the Supermicro web site for recommended memory modules.

Warning: Exercise extreme care when installing or removing DIMM

modules to prevent any possible damage. Also note that the memory

is interleaved to improve performance

Memory Support

This motherboard supports non-ECC Unbuffered Dual/Single Channel DDR3 1600
MHz up to 4G B i n 2 DI M Ms o r DD R3 1333 /106 6 /8 0 0 M Hz u p to 8G B i n 4 DI M Ms
(See notes 2 and 3). Populating DIMM1A, DIMM2A, and/or DIMM1B, DIMM2B
with memory modules of the same size and of the same type will result in dual
channel, two-way interleaved memory which is faster than the single channel, non­interleaved memory.
