Chapter 1: Introduction

1-2 Chipset Overview

The Intel® 82945GC chipset, designed for use with the Intel® LGA 775 processor
with a front side bus speed of up to 800 MHz, contains two components: GMCH
(North Bridge) and ICH7 (South Bridge). The GMCH is used for the host bridge,
and the ICH7, for the I/O subsystems.

Graphics Memory Controller Hub (GMCH)

The GMCH manages the data fl ow between its four interfaces: the processor
interface (FSB), the system memory interface (DRAM controller), the integrated
graphics interface, the External Graphics interface, and the I/O Controller through
DMI interface. It provides bus arbitration between the four interfaces when each
initiates transactions. The GMCH supports a 32-byte Cache Line, decoding up to 4
GB (2GB for the 945GC) of the CPU's usable memory address space. The GMCH
also supports one or two channels of SDRAM and the PCI Express-based graphics
attached devices.

The Intel® 945GC platform supports the seventh generation I/O Controller Hub (In­tel® ICH7) to provide a multitude of I/O related features. The Direct Media Interface
(DMI) provides the chip-to-chip connection between the GMCH and the ICH7.

Intel® I/O Controller Hub 7 (ICH7)

The I/O Controller (ICH7) 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 ICH7 supports PCI slots, Serial
ATA ports, USB 2.0 ports and dual channel IDE devices.

Intel® 82945GC Features

The Intel 945GC supports the following features:

PCI Express 2.0

•

Intel Flex Memory Technology•

Intel High Defi nition Audio•

Intel Matrix Storage Technology•

Intel Rapid Recover Technology•

X7SLM/X7SLM+ User’s Manual

1-3 PC Health Monitoring

This section describes the PC health monitoring features of the X7SLM/X7SLM+.
The motherboard has an onboard System Hardware Monitor chip that supports PC
health monitoring.

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 BIOS chapter of this manual to change this setting. The default
setting is Last State.

Onboard Voltage Monitoring

The onboard voltage monitor will scan the following voltages continuously: CPU
Cores, Chipset Voltage, Memory Voltage, +3.3V, +3.3V standby , +5V, +5V Standby,
Vbat and +12V. Once a voltage becomes unstable, it will give a warning or send
an error message to the screen. Users can adjust the voltage thresholds to defi ne
the sensitivity of the voltage monitor by using SD III.

Fan Status Monitor with Software

The PC health monitor can check the RPM status of the cooling fans via Supero
Doctor III.

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
temperature reaches the pre-defi ned threshold, the CPU thermal trip feature will be
activated and it will send a signal to the Speaker LED and, at the same time, the
CPU speed will be decreased.

1-4 Power Confi guration Settings

This section describes features of your motherboard that deal with power and
power settings.

1-10

Chapter 1: Introduction

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.

BIOS Support for USB Keyboard

If the USB keyboard is the only keyboard in the system, it will function like a normal
keyboard during system boot-up.

Main Switch Override Mechanism

When an ATX power supply is used, the power button can function as a system
suspend button. When the user presses the power button, the system will 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. The power will turn off
and no power will be provided to the motherboard.

1-5 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 of 1 GHz and faster.

The
most power supplies generally meet the specifi cations required by the CPU, some
are inadequate. A 2-Amp of current supply on a 5V Standby rail is strongly recom­mended.

It is strongly recommended that you use a high quality power supply that meets
12V ATX power supply specifi cation 1.1 or above. It is also required that the 12V
8-pin power connection (J41) be used for adequate power supply. 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.

X7SLM/X7SLM+ accommodates 12V ATX power supplies. Although

1-6 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 genera­tor, 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 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 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 provides functions that comply with ACPI (Advanced Confi guration
and Power Interface), which includes support of legacy and ACPI power manage­ment through a SMI or SCI function pin. It also features auto power management
to reduce power consumption.

2-1 Static-Sensitive Devices

Electrostatic-Discharge (ESD) can damage electronic com ponents. T o 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. Do not install the onboard
upside down battery 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.

2-2 Motherboard Installation

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. Although a chassis may have both plastic and metal mounting
fasteners, metal ones are highly recommended because they ground the mother­board to the chassis. 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.

Tools Needed

1. Philip Screwdriver

2. Pan head #6 screws

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 Intel-certifi ed multi-directional heatsink and fan. (This motherboard is
optimized for 1U.)

3. Make sure to install the motherboard into the chassis before you install
the CPU heatsink and fan.

Chapter 2: Installation

4. 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. Refer to the MB
Features Section for more details on CPU support.

Installing the LGA 775
Processor

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

Gently l ift t he loa d lever to ope n the lo ad 2.

Once aligned, carefully lower the CPU 6.
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.)

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

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

If the CPU is properly installed into the 9.
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.
