Introduction

1.2 Special Features of the System Board

PCI Express

PCI Express is a high bandwidth I/O infrastructure that possesses
the ability to scale speeds by forming multiple lanes. The system
board currently supports the physical layer of x1 and x16 lane
widths.

The x1 PCI Express lane supports transfer rate of 2.5 Gigabytes
(250MBbps) per second. The PCI Express architecture also provides
a high performance graphics infrastructure by doubling the capability
of the existing AGP 8x designs over a x16 PCI Express lane that
provides 4 Gigabytes per second transfer rate.

Hyper-Threading Technology Functionality Requirements

The system board supports Intel processors with Hyper-Threading
Technology. Enabling the functionality of Hyper-Threading Technology
for your computer system requires ALL of the following platforms.

Components:

• CPU - an Intel

• Chipset - an Intel® chipset that supports HT Technology

• BIOS - a BIOS that supports HT Technology and has it enabled

• OS - an operating system that includes optimizations for HT
Technology

Please refer to Appendix A for information about enabling the
functionality of the Hyper-Threading Technology. For more information
on Hyper-Threading Technology, go to: www.intel.com/info/
hyperthreading.

Introduction

CPU Overheat Protection

CPU Overheat Protection has the capability of monitoring the CPU’s
temperature during system boot up. Once the CPU’s temperature
exceeded the temperature limit pre-defined by the CPU, the system
will automatically shutdown. This preventive measure has been added
to protect the CPU from damage and insure a safe computing
environment.

DDR2

DDR2 is a higher performance DDR technology whose data transfer
rate delivers bandwidth of 4.3 GB per second and beyond. That is
twice the speed of the conventional DDR without increasing its
power consumption. DDR2 SDRAM modules work at 1.8V supply
compared to 2.6V memory voltage for DDR modules. DDR2 also
incorporates new innovations such as the On-Die Termination (ODT)
as well as larger 4-bit pre-fetch against DDR which fetches 2 bits
per clock cycle.

1

DDR1

DDR1 (Double Data Rate) is a type of SDRAM that doubles the
data rate through reading and writing at both the rising and falling
edge of each clock. This effectively doubles the speed of operation
therefore providing two times faster data transfer.

CMOS Reloaded

CMOS Reloaded is a technology that allows storing multiple user­defined BIOS settings by using the BIOS utility to save, load and
name the settings. This is especially useful to overclockers who
require saving a variety of overclocked settings and being able to
conveniently switch between these settings simultaneously.

Karajan Audio Card

The Karajan audio add-in card at the rear I/O panel supports 8­channel audio output via the audio jacks on the card.

11

Introduction

S/PDIF

S/PDIF is a standard audio file transfer format that transfers digital
audio signals to a device without having to be converted first to an
analog format. This prevents the quality of the audio signal from
degrading whenever it is converted to analog. S/PDIF is usually
found on digital audio equipment such as a DAT machine or audio
processing device. The S/PDIF connector on the system board sends
surround sound and 3D audio signal outputs to amplifiers and
speakers and to digital recording devices like CD recorders.

Serial ATA Interface

Serial ATA is a storage interface that is compliant with SATA 1.0
specification. With speed of up to 1.5Gbps, it improves hard drive
performance faster than the standard parallel ATA whose data
transfer rate is 100MB/s.

IEEE 1394 Interface

IEEE 1394 is fully compliant with the 1394 OHCI (Open Host
Controller Interface) 1.1 specification. It supports up to 63 devices
that can run simultaneously on a system. 1394 is a fast external bus
standard that supports data transfer rates of up to 400Mbps. In
addition to its high speed, it also supports isochronous data transfer
which is ideal for video devices that need to transfer high levels of
data in real-time. 1394 supports both Plug-and-Play and hot
plugging.

IrDA Interface

The system board is equipped with an IrDA connector for wireless
connectivity between your computer and peripheral devices. The
IRDA (Infrared Data Association) specification supports data
transfers of 115K baud at a distance of 1 meter.

USB Ports

12

The system board supports USB 2.0 and USB 1.1 ports. USB 1.1
supports 12Mb/second bandwidth while USB 2.0 supports 480Mb/
second bandwidth providing a marked improvement in device
transfer speeds between your computer and a wide range of
simultaneously accessible external Plug and Play peripherals.

Introduction

Dual Function Power Button

Depending on the setting in the “Soft-Off By PWR-BTTN” field of
the Power Management Setup, this switch will allow the system to
enter the Soft-Off or Suspend mode.

Wake-On-Ring

This feature allows the system that is in the Suspend mode or Soft
Power Off mode to wake-up/power-on to respond to calls coming
from an external modem or respond to calls from a modem PCI
card that uses the PCI PME (Power Management Event) signal to
remotely wake up the PC.

Important:

If you are using a modem add-in card, the 5VSB power source
of your power supply must support a minimum of ≥720mA.

1

Wake-On-LAN

This feature allows the network to remotely wake up a Soft Power
Down (Soft-Off) PC. It is supported via the onboard LAN port or
via a PCI LAN card that uses the PCI PME (Power Management
Event) signal. However, if your system is in the Suspend mode, you
can power-on the system only through an IRQ or DMA interrupt.

Important:

The 5VSB power source of your power supply must support

≥

720mA.

Wake-On-PS/2 Keyboard/Mouse

This function allows you to use the PS/2 keyboard or PS/2 mouse
to power-on the system.

Introduction

Wake-On-USB Keyboard/Mouse

This function allows you to use a USB keyboard or USB mouse to
wake up a system from the S3 (STR - Suspend To RAM) state.

Important:

• If you are using the Wake-On-USB Keyboard/Mouse
function for 2 USB ports, the 5VSB power source of your
power supply must support ≥1.5A.

• If you are using the Wake-On-USB Keyboard/Mouse
function for 3 or more USB ports, the 5VSB power source
of your power supply must support ≥2A.

RTC Timer to Power-on the System

The RTC installed on the system board allows your system to
automatically power-on on the set date and time.

ACPI STR

The system board is designed to meet the ACPI (Advanced
Configuration and Power Interface) specification. ACPI has energy
saving features that enables PCs to implement Power Management
and Plug-and-Play with operating systems that support OS Direct

system at once by pressing the power button or selecting “Standby”

®®

®

when you shut down Windows
through the sometimes tiresome process of closing files, applications
and operating system. This is because the system is capable of
storing all programs and data files during the entire operating session
into RAM (Random Access Memory) when it powers-off. The
operating session will resume exactly where you left off the next time
you power-on the system.

2.3.3 Installing the Fan and Heat Sink

The CPU must be kept cool by using a CPU fan with heat sink.
Without sufficient air circulation across the CPU and heat sink, the
CPU will overheat damaging both the CPU and system board.

Note:

• Use only certified fan and heat sink.

• The fan and heat sink package usually contains the fan and

heat sink assembly, and an installation guide. If the
installation procedure in the installation guide differs from
the one in this section, please follow the installation guide in
the package.

1. Before you install the fan / heat sink, you must apply a thermal

paste onto the top of the CPU. The thermal paste is usually
supplied when you purchase the CPU or fan heat sink assembly.
Do not spread the paste all over the surface. When you later
place the heat sink on top of the CPU, the compound will
disperse evenly.

24

Do not apply the paste if the fan / heat sink already has a patch
of thermal paste on its underside. Peel the strip that covers the
paste before you place the fan / heat sink on top of the CPU.

Hardware Installation

2. Place the heat sink on top of the CPU. The 4 studs around the
heat sink which are used to secure the heat sink onto the
system board must match the 4 mounting holes around the
socket.

Position each stud so that the groove faces the heat sink then
push it down firmly until it clicks into place.

Note:

You will not be able to secure the fan and heat sink
assembly in place if the groove is not facing the heat sink.
