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 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® 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 re-
quired for the system to operate ef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 De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 Con-
trol 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 de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 dene an overheat temperature. When this
temperature reaches the pre-de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Con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/X7SLM+ accommodates 12V ATX power supplies. Although
most power supplies generally meet the speci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 speci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 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.

1-6 Super I/O
The disk drive adapter functions of the Super I/O chip include a 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 genera-
tor, 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 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 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 Con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.
