1.2 Special Features of the System Board
AMD AthlonTM 64
The system board supports the AMD AthlonTM 64 processor. AMD
AthlonTM 64 provides superior computing for many software
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 AthlonTM 64 processor. You can select
the memory timing in the “1T/2T Memory Timing” field of the BIOS.
Refer to the Advanced Chipset Features section (“DRAM
Configuration” section) in chapter 3 for more information.
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.
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.
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.

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 mic-
in at the rear will be disabled. Use the front audio’s mic-in jack.
Serial ATA Interface with RAID
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. The system board allows configuring RAID
on SATA drives. It supports RAID 0, RAID 1 and JBOD.
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
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.
AGP (Accelerated Graphics Port)
AGP is an interface designed to support high performance 3D
graphics cards. It utilizes a dedicated pipeline to access system
memory for texturing, z-buffering and alpha blending. The AGP slot
supports AGP 8x with up to 2.13GB/sec. bandwidth and AGP 4x
with up to 1066MB/sec. bandwidth for 3D graphics applications.
AGP in this system board will deliver faster and better graphics to
your PC.
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.
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.
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 the system.
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 auto-
matically power-on on the set date and time.
AC Power Failure Recovery
When power returns after an AC power failure, you may choose to
either power-on the system manually or let the system power-on
automatically.
ACPI
The system board is designed to meet the ACPI (Advanced Con-
figuration 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®®
®®
®98/2000/ME/XP supports
the ACPI function allowing you to use the Suspend to RAM function.

Introduction

14
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®®
®®
®98/2000/ME/XP without having to
go through the sometimes tiresome process of closing files, applica-
tions 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.
Important:
The 5VSB power source of your power supply must support
≥ 1A.
Virus Protection
Most viruses today destroy data stored in hard drives. The system
board is designed to protect the boot sector and partition table of
your hard disk drive.

Warning:
Electrostatic discharge (ESD) can damage your system board, proces-
sor, disk drives, add-in boards, and other components. Perform the
upgrade instruction procedures described at an ESD workstation only.
If such a station is not available, you can provide some ESD
protection by wearing an antistatic wrist strap and attaching it to a
metal part of the system chassis. If a wrist strap is unavailable,
establish and maintain contact with the system chassis throughout
any procedures requiring ESD protection.
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.
Note:
If you are installing double rank DDR400 on both DDR 1 and
DDR 2 sockets, the maximum DRAM speed will automatically
be limited to the speed of a DDR333. However, the BIOS
provides the option of manually adjusting the speed to
DDR400 by selecting “200” in the “Max Memclock (Mhz)”
field (Advanced Chipset Features submenu) of the BIOS.
