AMD Athlon

The system board supports the AMD AthlonTM 64 processor. AMD
Athlon
applications by allowing both 32-bit and 64-bit applications to run
simultaneously on the same platform. The operating system and
software are able to process more data and access a tremendous
amount of memory which improves the overall system performance.

2T timing which provides better system stability is supported in CG
or later revisions of the AMD Athlon
the memory timing in the Genie BIOS Setting submenu (“DRAM
Configuration” section) of the BIOS.

AMD Cool‘n’QuietTM Technology

The AMD Cool‘n’QuietTM technology allows the system to detect the
CPU’s tasks and utilization status. When the CPU’s task slows down,
the system effectively lowers power consumption by lowering its
CPU speed and voltage, subsequently decreasing its noise level.

NVIDIA® SLITM (Scalable Link Interface) Technology

The NVIDIA® SLITM (Scalable Link Interface) technology connects
two SLI-ready PCI Express graphics cards in a single and scalable
system. The two identical graphics cards, which are connected via the
SLI bridge, will provide extreme performance allowing you to enjoy
games with the most visual effects and the most graphics
demanding multimedia utilities. Dual GPUs provide increased 3D
graphics and doubles the graphics performance.

Introduction

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 enhancing the capability
of a x16 PCI Express lane to provide 4 Gigabytes per second
transfer rate.

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.

DDR

12

Double Data Rate SDRAM (DDR SDRAM) 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 doubling the speed of data transfer.

6-channel Audio

The audio jacks at the rear panel will support 6-channel audio only
when the audio utility is configured to support this function. The mic­in at the rear will be disabled. Use the front audio’s mic-in jack.

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 with NVIDIA RAID

Serial ATA is a storage interface that is compliant with SATA 1.0
specification. With speed of up to 3Gb/s, it improves hard drive
performance faster than the standard parallel ATA whose data
transfer rate is 100MB/s. The system board supports NVIDIA RAID
that allows RAID arrays spanning across 4 Serial ATA and Parallel
ATA drives. It supports RAID 0, RAID 1, RAID 0+1 and JBOD.

IEEE 1394 Interface

IEEE 1394 is fully compliant with the 1394 OHCI (Open Host
Controller Interface) 1.1 specification. It suppor ts 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.

1

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.

13

1

Introduction

USB Ports

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.

Dual Function Power Button

Depending on the setting in the “Soft-Off By PBTN” 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.

14

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 por t 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.

Introduction

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.

Important:

The 5VSB power source of your power supply must support

≥

720mA.

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. 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.

1

ACPI

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
Power Management. Currently, only Windows
the ACPI function. ACPI when enabled in the Power Management
Setup will allow you to use the Suspend to RAM function.

With the Suspend to RAM function enabled, you can power-off the
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.

The system board supports DDR SDRAM DIMM. Double Data
Rate SDRAM (DDR SDRAM) 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 doubling the speed of data transfer. Refer to chapter 1
(System Memory section) for detailed specification of the memory
supported by the system board.

Single/Dual Channel Memory

The four DDR DIMM sockets on the system board are divided into 2
channels:

Channel A - DDR 1 and DDR 3
Channel B - DDR 2 and DDR 4

Hardware Installation

The system board supports the following memory interface.

Single Channel (SC)

Data will be accessed in chunks of 64 bits (8B) from the memory
channels.

Dual Channel (DC)

Data will be accessed in chunks of 128 bits from the memory
channels. Dual channel provides better system performance because
it doubles the data transfer rate.

Important Notes on Memory Usage

1. The system board will fail to boot when 3 DIMMs are used.

The integrated memory controller in AMD's 64-bit Socket 939
series CPU supports dual channel however when 3 DIMMs are
installed, the controller is not capable of accurately distinguishing
between dual and single channels resulting to boot up problem.
Even if you have luckily booted the system, the total memory
size detected is from 2 DIMMs only, not 3. Therefore we do not
suggest using 3 DIMMs.

2. The table below lists different memory configurations and their
corresponding memory speed. Take note that some memory
configurations will automatically reduce the memory speed to
DDR333.

Hardware Installation

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.

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.
