To prevent electrical shock hazard, disconnect the power cable from the
electrical outlet before relocating the system.
•
When adding or removing devices to or from the system, ensure that the
power cables for the devices are unplugged before the signal cables are
connected. If possible, disconnect all power cables from the existing
system before you add a device.
•
Before connecting or removing signal cables from the motherboard,
ensure that all power cables are unplugged.
•
Seek professional assistance before using an adapter or extension cord.
These devices could interrupt the grounding circuit.
•
Make sure that your power supply is set to the correct voltage in your

Employing the Double Data Rate (DDR) memory technology, the
motherboard supports up to 4GB of system memory using DDR400/333/
266 DIMMs. The ultra-fast 400MHz memory bus delivers the required
bandwidth for the latest 3D graphics, multimedia, and Internet applications.

The motherboard supports the next-generation Serial ATA 3Gb/s
technology through the Serial ATA interfaces and the NVIDIA® nForce™ 4
Ultra chipset. The SATA 3Gb/s specification provides twice the bandwidth
of the current Serial ATA products. Additionally, Serial ATA allows thinner,
more flexible cables with lower pin count, and reduced voltage requirement.
See pages 1-25.

Take note of the following precautions before you install motherboard
components or change any motherboard settings.
• Unplug the power cord from the wall socket before touching any
component.
• Use a grounded wrist strap or touch a safely grounded object or to
a metal object, such as the power supply case, before handling
components to avoid damaging them due to static electricity
• Hold components by the edges to avoid touching the ICs on them.
• Whenever you uninstall any component, place it on a grounded
antistatic pad or in the bag that came with the component.

The motherboard comes with a surface mount 939-pin Zero Insertion Force
(ZIF) socket designed for the AMD Athlon™ 64FX, AMD Athlon 64™ or AMD
Sempron™ processor.
The 128-bit-wide data paths of these processors can run applications
faster than processors with only 32-bit or 64-bit wide data paths.
Take note of the marked corner (with
gold triangle) on the CPU. This mark
should match a specific corner on the
socket to ensure correct installation.

Make sure that the socket lever is lifted up to 90°-100° angle, otherwise
the CPU does not fit in completely.
3. Position the CPU above the
socket such that the CPU corner
with the gold triangle matches
the socket corner with a small
triangle.
4. Carefully insert the CPU into the
socket until it fits in place.
The CPU fits only in one correct orientation. DO NOT force the CPU into
the socket to prevent bending the pins and damaging the CPU!
5. When the CPU is in place, push
down the socket lever to secure
the CPU. The lever clicks on the
side tab to indicate that it is
locked.

Installing the heatsink and fanInstalling the heatsink and fan
Installing the heatsink and fan
Installing the heatsink and fanInstalling the heatsink and fan
The AMD Athlon™ 64FX or AMD Athlon 64™ processor require a specially
designed heatsink and fan assembly to ensure optimum thermal condition
and performance.
Make sure that you use only qualified heatsink and fan assembly.
Follow these steps to install the CPU heatsink and fan.
1. Place the heatsink on top of the installed CPU, making sure that the
heatsink fits properly on the retention module base.
• The retention module base is already installed on the motherboard
upon purchase.
• You do not have to remove the retention module base when
installing the CPU or installing other motherboard components.
• If you purchased a separate CPU heatsink and fan assembly, make
sure that a Thermal Interface Material is properly applied to the CPU
heatsink or CPU before you install the heatsink and fan assembly.

2. Attach one end of the retention bracket to the retention module
base.
3. Align the other end of the retention bracket (near the retention
bracket lock) to the retention module base. A clicking sound denotes
that the retention bracket is in place.
Make sure that the fan and
heatsink assembly perfectly
fits the retention mechanism
module base, otherwise you
cannot snap the retention
bracket in place.
4. Push down the retention bracket lock on the retention mechanism to
secure the heatsink and fan to the module base.

You may install 256 MB, 512 MB and 1 GB unbuffered ECC or non-ECC DDR
DIMMs into the DIMM sockets using the memory configurations in this
section.
•
For dual-channel configuration, the total size of memory module(s)
installed per channel must be the same for better performance
(DIMM_A1+DIMM_A2=DIMM_B1+DIMM_B2).
•
When using one DDR DIMM module, install into DIMM_B1 slot only.
•
When using two DDR DIMM modules, install into DIMM_A1 and
DIMM_B1 slots only.
•
Always install DIMMs with the same CAS latency. For optimum
compatibility, it is recommended that you obtain memory modules
from the same vendor. Refer to the DDR400 Qualified Vendors List
on the next page for details.
