________________________________________________________________________
Overview 1-1
DK8X Motherboard
GENERAL SAFETY PRECAUTIONS
Keep the area around the Server clean and free of clutter.
Servers weigh a lot. They can average about 50 lbs. (~22.68 kg)
When lifting the system, two people should lift slowly from opposite ends with their
feet spread out to distribute the weight. Always keep your back straight and lift with
your legs.
Place the chassis top cover and any system components that have been removed
away from the system or on a table so that they won¡¦t accidentally be stepped on.
While working on the system, do not wear loose items such as neckties and
unbuttoned shirt sleeves. They can come into contact with electrical circuits or get
pulled into a cooling fan.
Remove any jewelry or metal objects from your body, which are excellent metal
conductors and can create short circuits and harm you if they come into contact with
printed circuit boards or areas where power is present.
ESD
PRECAUTIONS
Electrostatic discharge (ESD) is generated by two objects with different electrical charges
coming into contact with each other. An electrical discharge is created to neutralize this
difference, which can damage electronic components and printed circuit boards. The
following measures are generally sufficient to neutralize this difference before contact is
made to protect your equipment from ESD:
Use a grounded wrist strap designed to prevent static discharge.
Keep all components and printed circuit boards (PCBs) in their antistatic bags until ready
for use.
________________________________________________________________________
1-2 Overview
Chapter 1 Overview
Touch a grounded metal object before removing the board from the antistatic bag.
Do not let components or PCBs come into contact with your clothing, which may
retain a charge even if you are wearing a wrist strap.
Handle a board by its edges only; do not touch its components, peripheral chips,
memory modules or contacts.
When handling chips or modules, avoid touching their pins.
Put the motherboard and peripherals back into their antistatic bags when not in use.
For grounding purposes, make sure your computer chassis provides excellent
conductivity between the power supply, the case, the mounting fasteners and the
motherboard.
After accessing the inside of the system, close the system back up and secure it to
the rack unit with the retention screws after ensuring that all connections have been
made.
O
PERATING PRECAUTIONS
Care must be taken to insure that the chassis cover is in place when the server is
operating to assure proper cooling.
Out of warranty
damage to the server can occur if
this practice is not strictly followed.

INSTALLING MEMORY
This Mainboard uses Dual Inline Memory Modules (DIMM). Eight DIMM socket
memory banks are available, four memory bank for each CPU socket. The DIMM sockets
accommodate 184-pin PC2100/PC2700/PC3200 (DDR266/DDR333/DDR400) and
Double Data Rate (DDR) memory modules in 128MB, 256MB, 512MB, 1GB and 2GB
size combinations. Total installed memory size is between a minimum of 128MB to a
maximum of 16GB.
IMPORTANT
* The Mainboard has strict memory and timing requirements. Before buying DDR
(Double Data Rate) DIMMs for use with the Mainboard, it is recommended that
you consult your local reseller for the best and most compatible memory to use.
* This Mainboard only supports Registered PC2100/PC2700 (DDR266/DDR333)
compliant modules.
________________________________________________________________________
Hardware Installation 2-7
DK8X Motherboard
Memory Installation Procedures
This section outlines how to install Registered PC2100/PC2700/PC3200 DDR DIMMs
into the Mainboard.
1. Locate the Memory Bank on the Mainboard, where you will be installing the DIMMs.
2. Make sure the DIMM’s pins are facing down, and check that the pin arrangement on
the memory module resembles the one pictured below.
________________________________________________________________________
2-8 Hardware Installation
Chapter 2 Hardware Installation
3. Insert the module into the DIMM socket and press down evenly on both ends firmly
until the DIMM module is securely in place. (The tabs of the DIMM socket will
close-up to hold the DIMM in place when the DIMM is properly installed on the
socket’s bottom.)
4. Repeat step 1 to step 3 for all additional DIMM modules.
IMPORTANT
* The Opteron features a 128-bit wide DDR memory interface. To take advantage
of the 128-bit interface, you must install DIMMs in pairs of two (2). DIMM slots
A1 and B1 are paired, and slots A2 and B2 are paired. If you are only installing
two DIMMS into a Memory Bank, it is recommended that you install them in
slots A1 and B1 to get the full bandwidth.
* To ensure compatibility, only use DIMM pairs of the same exact type and size
and made by the same company.
________________________________________________________________________
Hardware Installation 2-9
DK8X Motherboard
RECOMMENDED MEMORY CONFIGURATIONS
The AMD Opteron processors have very specific memory module requirements, and due
to the design of the Mainboard, there are certain configurations of memory that work best
to make the most effective use of the memory bandwidth.
The AMD Opteron features 128-bit DDR memory channels. DDR Memory Modules are
only 64-bit. In order to benefit from the full bandwidth, you should always install the
DIMMs in pairs. The Mainboard is designed to pair up DIMM slots A0/B0, A1/B1,
A2/B2 and slots A3/B3 for the 128-bit pathway.
The DIMM memory banks are shared over the dual CPU sockets. It is possible to operate
a system with two CPUs and only a pair of DIMMs in the memory bank.
The following is our recommended DIMM installation path based on the number of
DIMMS being installed (Remember to check that the DIMMS are 2.5V Registered ECC
DDR PC2100/ PC2700/PC3200 DDR266/ DDR333/DDR400 DIMMs)

INSTALLING EXPANSION CARDS
This outlines the procedure for adding expansion cards to your Mainboard. Remember to
read the documentation for your expansion cards and make the necessary hardware and
software setting changes (i.e. jumper settings).
The Mainboard features two (2) PCI-32 (32-bit, 33MHz) slots, one (1) PCI-64 (64-bit,
66/33MHz) slot and two (2) PCI-X (100/133MHz) slots to accommodate PCI expansion
cards.
1. Remove the bracket plate on the slot you intend to use. Keep the bracket for possible
future use.
2. Insert the PCI card into the correct slot on the Mainboard, pushing down with your
thumbs evenly on both sides of the card.
3. Secure the card on the slot with the screw you removed above.
4. Assign IRQs for PCI expansion card: An IRQ number is automatically assigned to PCI
expansion card. In the PCI bus design, the BIOS automatically assigns an IRQ to a PCI
slot that contains a card requiring an IRQ.
WARNING
Completely power OFF your power supply when adding or removing any expansion
cards or other system components. Failure to do so may cause severe damage to both
your Mainboard and expansion cards.

POWERING ON YOUR SYSTEM
Follow these instructions to power on the computer after you have installed the
Mainboard and all system devices.
1. Be sure that all switches are off (in some systems, Off is marked by “O”).
2. After double-checking all jumper settings and connections, close the system chassis
cover.
3. Connect the power cord to the power cord connector located on the power supply at
the back of your system chassis and plug the power cord into a power outlet that is
equipped with a surge protector.
4. Turn on your devices in the following order:
- Monitor
- External SCSI devices (starting with the last device on the chain if connected)
- System power For power supplies, you need to switch On the power supply, then
press the:
1. Power switch on the front of the chassis the first time you start up the system.
2. The power LED on the front panel of the system case will light up. For power
supplies, the system LED will light up when the power switch is pressed. The monitor
LED may light up after the system’s LED if it complies with “Green” standards or if
it has a power standby feature. The system will first run its “power-on” tests. While
the tests are running, additional messages will appear on the screen. If you do not see
anything on the screen within 30 seconds from the time you turn on the power, the
system may have failed a power-on test. Re-check your jumper settings and
connections. Contact your retailer/dealer for assistance if everything else fail.
3. During power-on, hold down <F2> to enter BIOS setup. Follow the instructions in
BIOS for further setup information.

BIOS Setup
This chapter discusses the AMIBIOS Setup program built into the ROM BIOS. The Setu p
program allows users to modify the basic system configuration.
The BIOS is the Basic Input / Output System used in all IBM PC, XT, AT, and PS/2
compatible computers. The AMIBIOS flash chip stores the system parameters, such as
type of disk drives, video displays, etc. in the CMOS. When the computer is turned off, a
back-up battery provides power to the BIOS flash chip, enabling it to retain system
parameters. Each time the computer is powered-on the computer is configured with the
values stored in the BIOS ROM by the system BIOS, which gains control at boot-up.
The AMIBIOS installed in your computer system’s ROM (Read Only Memory) is a
custom version of an industry standard BIOS. The BIOS provides critical low-level
support for standard devices such as disk drives and serial and parallel ports.
TARTING THE BIOS SETUP
S
The AMIBIOS is immediately activated every time you power on the system. The BIOS
reads the system information contained in the CMOS and begins the process of checking
the system and configuring it. After configuring the system, the BIOS will follow the
Boot Order to seek out an operating system. The BIOS then turns control of the system
over to the operating system.
The CMOS information that determines the system parameters may be changed by
entering the BIOS Setup utility.
1. Power on the System.
Note: Normally, the only visible POST (Power On Self Test) routine is the
memory test.

From the main menu of the BIOS Setup Utility, you can access the other setup screens,
such as the Security and Power menus.

IMPORTANT
The BIOS does NOT automatically save values that you have modified. If you do not
save your values before you exit the BIOS Setup Utility, all your changes will be lost.
If after making and saving system changes with the BIOS Setup Utility, you discover that
your computer is no longer able to boot, the AMIBIOS supports an override, which will
reset your system to the Failsafe defaults. If that fails, it is possible to manually clear the
present CMOS information through the "Clear CMOS Header" on the motherboard
(Refer to Jumper Settings for more information).
The best advice is to ONLY alter settings which you thoroughly understand. The default
settings have been carefully chosen by AMIBIOS to provide the maximum system
performance and reliability. Even a slight change to the chipset setup may cause potential
and unpredictable failure to the system.
