for dual-processor systems with conguration options optimized for intensive ap-
plication and high-end workstation platforms.
The main architecture of the X8SAX/C7X58 consists of an LGA 1366 processor
socket, the Intel X58 Express North Bridge chipset, the ICH10R South Bridge, and
the PXH/V IO Bridge. With Intel QuickPath Interconnect technology built in, the
X8SAX/C7X58 is one of the rst motherboards on the market that offer the next
generation point-to-point system interconnect interface, replacing the current Front
Side Bus Technology, providing substantial system performance enhancement by
utilizing serial link interconnections to increase bandwidth and scalability.

1-3 PC Health Monitoring
This section describes the PC health monitoring features of the X8SAX/C7X58.
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
Core, Chipset Voltage, Memory Voltage, +1.8V, +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 dene the sensitivity of the voltage monitor by using SD III.
Fan Status Monitor with Software
PC health monitoring 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 feature
in the BIOS. This allows the user to dene an overheat temperature. When this
temperature reaches this pre-dened overheat threshold, the CPU thermal trip
feature will be activated and it will send a signal to the buzzer and, at the same
time, the CPU speed will be decreased.
1-4 PowerCongurationSettings
This section describes the features of your motherboard that deal with power and
power settings.
Chapter 1: Introduction
1-13
Slow Blinking LED for Suspend-State Indicator
When the CPU goes into a suspend state, the chassis power LED will start blink-
ing to indicate that the CPU is in the suspend mode. When the user presses any
key, the CPU will wake-up and the LED indicator 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 to wake-up the whole system. During the SoftOff
state, the ATX power supply provides power the system to keep the required cir-
cuitry "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 X8SAX/C7X58 accommodates ATX12V standard power supplies.
Although most power supplies generally meet the specications 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
ATX12V standard power supply Specication 1.1 or above. It is also required that
the 12V 8-pin power connection (JPW2) be used for adequate power supply. How-
ever, the 12V 4-pin power connection (JPW3) is optional, but may be necessary
when increased power to the installed peripheral cards is needed. 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 Conguration
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 dam-
age to your system board, it is important to handle it very carefully. The following
measures are generally sufcient 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.

2-3 Mounting the Motherboard into the Chassis
All motherboards have standard mounting holes to t different types of chassis.
Make sure that the locations of all mounting holes for the motherboard and the chas-
sis 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. (See the
layout on the right for mounting hole locations.)
Note: Some components are very close to the mounting holes. Please take
all necessary precautionary measures to avoid damaging these compo-
nents when installing the motherboard into the chassis.
