Frequent Q&A on Memory Usage
Q: How can I manually enhance the compatibility of the system
memory?
A: 1. Leave JP17's jumper cap in its default setting, pins 1 and 2.
2. Set the "DRAM Voltage Control" field (in the Genie BIOS
Setting of the Award BIOS) to "2.8V".
3. Insert DIMMs in DIMM 2 and DIMM 4.
4. Always check DFI's website for the latest BIOS. Newer
updates may be available for enhancing memory compatibility.
Q: How can I obtain good performance on an overclocked system?
A: Insert two identical broad bandwidth memories in DIMM 2 and
DIMM 4.
Q: Why will the system board fail to boot when 3 DIMMs are
used?
A: The integrated memory controller in AMD's 64-bit Socket 939
series CPU supports dual channel however the controller is not
capable of accurately distinguishing between dual and single
channels resulting to boot up problem. 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.
Q: Why won't the system boot when 4 single side DIMMs are
used?
A: Normally, the memory timing is set at 2T but to enhance system
performance, the default memory timing has been fixed at 1T
(Command Per Clock: Enabled) on all nF4 series system boards.
Therefore if you use 4 single side DIMMs, the load will exceed
the limit (DDR 400). Please refer to the steps below to solve
this problem.
1. Set the "DRAM Voltage Control" field (in the Genie BIOS
Setting of the Award BIOS) to "2.8V".
2. Set the memory timing to 2T by selecting Disabled in the
"Command Per Clock" field (in the Genie BIOS Setting of the
Award BIOS).

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 Genie BIOS Setting submenu (“DRAM
Configuration” section) of the BIOS.
NVIDIA®SLITM (Scalable Link Interface) Technology (for “nF4 SLI”
models only)
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 and doubles the graphics performance.
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.

Introduction
13
NVIDIA®ActiveArmorTM
NVIDIA®ActiveArmorTM is built into the chipset to enhance network
security. It protects the system’s networking connection especially during
large file downloads. ActiveArmor is activated the minute you turn on
the PC. It performs a thorough inspection of the data packets that
flow in and out of your network connection and only allows good
packets to pass through the firewall. ActiveArmor performs network
and security processing in the chipset, leaving the CPU free for other
important application processing.
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
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.
CMOS Reloaded
CMOS Reloaded is a technology that allows storing multiple user-
defined 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 Module
The Karajan audio module at the rear I/O panel supports 8-channel
audio output via the audio jacks on the module. It is also equipped
with a CD-in and front audio connector.

Introduction
1
14
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. nForce4 SLI and nForce4 Ultra support 4 Serial ATA
ports with speed of up to 3Gb/s which is twice as fast as the
standard 1.5Gb/s speed supported by Silicon Image that controls
another 4 Serial ATA ports. Serial ATA it improves hard drive
performance faster than the standard parallel ATA whose data
transfer rate is 100MB/s.
RAID (Redundant Array of Inexpensive Disk)
The NVIDIA nForce4 chipset supports NVIDIA RAID that allows
RAID arrays spanning across 4 Serial ATA and Parallel ATA drives. It
supports RAID 0, RAID 1 and RAID 0+1.
The Silicon Image Sil 3114 chip (for “DR” models only) allows
configuring RAID on another 4 Serial ATA ports. It supports RAID
0, RAID 1, RAID 0+1 and RAID 5.
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.

Introduction
15
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.
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-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.

Introduction
1
16
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
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
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.
AC Power Failure Recovery
When power returns after an AC power failure, you may choose to
either power-on the system manually, let the system power-on
automatically or return to the state where you left off before power
failure occurs.

2.2 System Memory
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 (System Memory section) for detailed specifica-
tion of the memory supported by the system board. The four DDR
DIMM sockets on the system board are divided into 2 channels:
