1-2 Chipset Overview
The Intel® 82945GC chipset, designed for use with a single Intel® Core™ 2 Duo/
Pentium® dual-core/Pentium D/Pentium 4/Celeron® dual-core/Celeron/Celeron D
Processor with a system bus speed of up to 800 MHz in an LGA 775 socket, contains
two components: GMCH (North Bridge) and ICH7R (South Bridge). The GMCH is
used for the host bridge, and the ICH7R, 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 (In-
tel® ICH7R) 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 ICH7R.
Intel® I/O Controller Hub 7R (ICH7R)
The I/O Controller (ICH7R) 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 ICH7R supports PCI slots, Se-
rial ATA ports, USB 2.0 ports and dual channel IDE devices. In addition, the ICH7R
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 controllers.

X7SLM-L User’s Manual
1-3 PC Health Monitoring
This section describes the PC health monitoring features of the X7SLM-L. 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 set-
ting is Last State.
Onboard Voltage Monitoring
The onboard voltage monitor will scan the following voltages continuously: CPU
Cores, Chipset Voltage, Memory Voltage (+1.8V), +3.3V, +3.3V standby, +5V, +5V
Standby, +12V, -12V and Vbat. Once a voltage becomes unstable, it will give a
warning or send an error message to the screen. The User 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.
Chapter 1: Introduction
1-11
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
X7SLM-L accommodates 12V ATX power supplies. Although 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 recom-
mended.
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 (JPW2) 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-L User’s Manual
1-6 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 wide range of functions
integrated onto the Super I/O greatly reduces the number of components required
for interfacing with I/O devices.
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 ACPI (Advanced Confi guration
and Power Interface), which includes support of legacy and ACPI power manage-
ment 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. To
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 fas-
teners, 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.
Caution: 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.

Installation Instructions
Install the I/O shield into 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
motherboard installation.
Locate the mounting holes on the motherboard. Refer to the layout on the
previous page for mounting hole locations.
Locate the matching mounting holes on the chassis. Install standoffs in the
chassis as needed. Align the mounting holes on the motherboard against the
mounting holes on the chassis.
Install the motherboard into the chassis carefully to avoid damage to mother-
board components.
Insert a Pan head #6 screw into a mounting hole on the motherboard and its
matching mounting hole on the chassis, using the Philips screwdriver.
Repeat Step 4 to insert #6 screws to all mounting holes.

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 add-
ing, 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 boxed Intel LGA 775 processor 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 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.

Warning: The CPU will only seat inside the socket in one direction. Make
sure it is properly inserted before closing the load plate. If it doesn't close
properly, do not force it as it may damage your CPU. Instead, open the
load plate again and double-check that the CPU is aligned properly.
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 the four corners of the CPU to make sure
that the CPU is properly installed.
Use your thumb to gently push the load lever down to the lever lock.
