Static Electricity Precautions
It is quite easy to inadvertently damage your PC, system board,
components or devices even before installing them in your system
unit. Static electrical discharge can damage computer components
without causing any signs of physical damage. You must take extra
care in handling them to ensure against electrostatic build-up.
1. To prevent electrostatic build-up, leave the system board in its
anti-static bag until you are ready to install it.
2. Wear an antistatic wrist strap.
3. Do all preparation work on a static-free surface.
4. Hold the device only by its edges. Be careful not to touch any of
the components, contacts or connections.
5. Avoid touching the pins or contacts on all modules and
connectors. Hold modules or connectors by their ends.
Important:
Electrostatic discharge (ESD) can damage your processor, disk
drive 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.
Safety Measures
To avoid damage to the system:
• Use the correct AC input voltage range.....
To reduce the risk of electric shock:
• Unplug the power cord before removing the system chassis
cover for installation or servicing. After installation or servicing,
cover the system chassis before plugging the power cord.

Features
The system board supports the AMD AthlonTM 64 proc-
essor. 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 im-
proves 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 Genie BIOS Setting submenu (“DRAM
Timing and Config” section) of the BIOS.
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 effec-
tively lowers power consumption by lowering its CPU speed and
voltage, subsequently decreasing its noise level.
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 sec-
ond. The PCI Express architecture also provides a high performance
graphics infrastructure by enhancing the capability of a x16 PCI Ex-
press lane to provide 4 Gigabytes per second transfer rate.

The graphics integrated in the GeForceTM 6100 GPU
(Graphics Processing Unit) supports Microsoft®
DirectX®9.0 Shader Model 3.0 and NVIDIA®
PureVideoTM technology that delivers realistic effects
and multimedia functionality for an incredible PC performance on
popular games and multimedia applications.
NVIDIA®PureVideoTM technology is a combination of
high-definition video processors and video decoding
software that delivers HD (High-Definition) video to
your PC.
CPU Overheat Protection has the capability of moni-
toring the CPU’s temperature during system boot up.
Once the CPU’s temperature exceeded the tempera-
ture limit pre-defined by the CPU, the system will automatically shut-
down.This preventive measure has been added to protect the CPU
from damage and insure a safe computing environment.
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.
The onboard Realtek ALC655 is an AC’97 compatible
audio codec that will support 6-channel audio only
when the audio utility is configured to support this func-
tion. The mic-in at the rear will be disabled. Use the
front audio’s mic-in jack.

S/PDIF is a standard audio file transfer format that trans-
fers 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 equip-
ment 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 re-
cording devices like CD recorders.
Serial ATA is a storage interface that is compli-
ant with SATA 1.0 specification. nForceTM 410
MCP (Media and Communications Processor) supports Serial ATA
speed of up to 3Gb/s. Serial ATA improves hard drive performance
faster than the standard parallel ATA whose data transfer rate is
100MB/s.
nForceTM 410 MCP allows configuring RAID on the Serial
ATA drives. It supports RAID 0 and RAID 1.
The onboard Realtek RTL8201CL LAN Phy supports up
to 100Mbps.
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.

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.
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 mo-
dem 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.
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.
This function allows you to use the PS/2 key-
board or PS/2 mouse to power-on the sys-
tem.
Important:
The 5VSB power source of your power supply must support
≥ 720mA.

This function allows you to use a USB key-
board 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.
The RTC installed on the system board allows your
system to automatically power-on on the set date and
time.
The system board is designed to meet the ACPI (Ad-
vanced 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®®
®®
®
2000/XP supports 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®®
®®
®2000/XP without having to go
through the sometimes tiresome process of closing files, applications
and operating system. This is because the system is capable of stor-
ing all programs and data files during the entire operating session
into RAM (Random Access Memory) when it powers-off. The oper-
ating 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.

Warning:
When the DRAM Power LED lit red, it indicates that power is
present on the DDR sockets. Power-off the PC then unplug the
power cord prior to installing any memory modules. Failure to do so
will cause severe damage to the motherboard and components.
Warning:
Electrostatic discharge (ESD) can damage your system board,
processor, 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
