(E) Notices for Assembling Computers:
1. Cases should be made of iron or other metal that has good electric conductivity.
2. Cylinders in a case should be made of metal, and as having a mainboard mounted
in a case, make sure screws are all utilized and fastened on a mainboard.
3. An I/O shielding should be contacted with I/O metallic parts of a mainboard.
4. Cables should appropriately be arranged and fixed in a case. Follow instructions:
Ø Leave IDE cables not crossed upon CPU and SDRAM;
Ø Leave power cables minimum in length, and not crossed upon a mainboard;
Ø Leave CPU fan cables minimum in length, and not near CPU;
Ø Leave cables on panels and other spare cables tied in a computer case.
5. Make sure an EMI shielding attached to a case has properly been installed.
6. Make sure a 5.25" or 3.5" FDD and screws are fastened to an EMI shielding.
7. Make sure a case is closely in contact with EMI connected points.
8. Make sure there is no cleft in a case which is not deformed.
9. Make sure a PCI orAGP door is bound to a case.
10. Make sure cables of other devices (fans or some others) are fixed in a case.

Step 1
Install the CPU:
1. Locate the CPU ZIF (Zero Insertion Force) socket on the upper-right sector
of your mainboard (between the back panel connectors and the DIMM
memory slots).
2. Pull the CPU ZIF socket lever slightly sideways away from the socket to
unlock the lever, and then bring it to an upwardly vertical position.
3. Place your AMD Athlon TM 64 processor in the socket . Note that the CPU's
edges have been purposely designed non-symmetrically to prevent from in
serting the processor in the wrong direction. The following diagram demon
strates the correct placement of the CPU in the ZIF socket.
4. Slightly push the AMD Athlon TM 64 processor into the socket without apply
ing excessive force while making sure there is no gap between CPU and
socket. Then lower the socket-lever all the way down to its horizontal posi-
tion and lock it to secure the CPU in place.
5. The AMD Athlon TM 64 processor requires a set of heatsink/fan to ensure
proper cooling of the processor. If heatsink/fan have not been already
mounted on your CPU, you must purchase the heatsink/fan separately and
have it in stalled. Plug the cable throught the heatsink/fan in the CPU fan
power connector located nearby. Note that there are several types of CPU
fan connectors. Normally, if your mainboard supports the hardware moni
toring function, a 3-pin fan power connector should allow your system to
detect the CPU fan's speed. The CPU fan can also run with a 2-pin fan power
connector, however, detection of CPU fan's speed is not supported. An
other type of CPU fan may feature a large 4-pin fan power connector, which
does not support CPU fan's speed detection and must be directly connected
to the system's power supply unit. Please refer to the following diagram.

Step 2.
Set Jumpers
The default jumper settings have been set for the common usage standard of
this mainboard. Therefore, you need not to reset the jumpers unless you re-
quire special adjustments as the following case:
Clear CMOS Setting
For first-time DIY system builders, we recommend that you not change the
default jumper settings if you are not quite familiar with the mainboard con-
figuration procedures. The factory-set default settings are tuned for optimum
system performance. For advanced users who prefer to customize their sys-
tem, section 3.2 Jumper Settings provides the detailed information on how
to configure your mainboard manually.
Step 3
Install DDR SDRAM System Memory
To install memory, insert DDR SDRAM memory module(s) in the DIMM
banks. Note that DDR SDRAM modules are directional and will not go in the
DIMM banks if they are not properly oriented. After the module is fully in-
serted into the DIMM bank, lift the clips of both sides of the DIMM bank to
lock the module in place.

Step 4
Install Internal Peripherals in System Case
Before you place the mainboard into your system case, we recommend that
you first assemble all the internal peripheral devices into the computer hous-
ing, including, but not limited to, the hard disk drive (IDE/HDD), floppy disk
drive (FDD), CD-ROM drive, and ATX power supply unit.
To install IDE & FDD drives, follow these procedures:
1. Set the required jumpers on each device according to the instructions pro-
vided by the manufacturer. (IDE, HDD, and CD-ROM have to set jumpers
to Master or Slave mode depending on whether you install more than one
device of each kind.)
2. Connect the IDE cable and FDD cable on the back panel of the internal
peripheral devices to the corresponding headers on board. Note that the
cable should be oriented with its colored stripe (usually red or magenta)
connected to pin#1 of the IDE or FDD connector on the mainboard and
on the device as well.
3. Connect an available power cable from your system power supply unit to
the back panel of each peripheral device. Note that the power cable is di-
rectional and cannot fit in if not properly positioned.

Step 5
Mount the Mainboard on the Computer Chassis
1. You may find there are a lot of mounting holes on your computer chassis
and mainboard. To match the holes on both properly, the key point is to
make the back panel of the mainboard in a close fit with your system case,
as shown below.
2. Position the studs between the chassis and the mainboard. The studs are
used to fix the mainboard and to keep a certain distance between them,
for avoiding any electrical shorts in-between.
(If your computer case is already equipped with mounting studs, you need
to tighten the screws to attach the mainboard.)
Note: In most computer housings, you can find 4 or more holes to place
studs for fixing the mainboard. If there aren't enough matching holes,
screw at least 4 studs to ensure the proper attachment of the main-
board.

Step 6
Connect Front Panel LEDs/Switches/Speaker/USBs
You can find there are several cables existing in the system case and originat-
ing from the front panel devices (HDD LED, Green LED, Reset switch, PC
Speaker, and USB devices etc.). These cables serve to connect the front-panel
LEDs, switches, speaker, and USB connectors to the mainboard's front-panel
connectors group, as shown below.
1. Green LED (GLED)
2. HDD LED (HLED)
3. ATX Soft Power On/Off (PWON)
4. Hardware Reset Switch (RST)
5. Power LED (PLED)
6. Hardware System Management
Interface (EPMI)
7. PC Speaker (SPEAKER)
8. Extended USB Headers (JP7-USB 5&6)
