Installing 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.

Your boxed CPU heatsink and fan assembly should come with installation
instructions for the CPU, heatsink, and the retention mechanism. If the
instructions in this section do not match the CPU documentation, follow
the latter.

Chapter 1: Product introduction
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.

Memory Configurations
You may install 256 MB, 512 MB, and 1 GB unbuffered non-ECC DDR DIMMs
into the DIMM sockets using the memory configurations in this section.
•
Installing DDR DIMMs other than the recommended configurations
may cause memory sizing error or system boot failure. Use any of
the recommended configurations on the next page.
•
Always install DIMMs with the same CAS latency. For optimum
compatibility, we recommend that you obtain memory modules from
the same vendor.
•
Due to chipset resource allocation, the system may detect less than
3 GB system memory when you installed three 1 GB DDR memory
modules.
•
This motherboard does not support memory modules made up of
128 Mb chips or double sided x16 memory modules.

installed in a chassis).
3.
Remove the bracket opposite the slot that you intend to use. Keep
the screw for later use.
4.
Align the card connector with the slot and press firmly until the card is
completely seated on the slot.
5.
Secure the card to the chassis with the screw you removed earlier.
6.
Replace the system cover.
1.8.2
Configuring an expansion card
After installing the expansion card, configure the it by adjusting the
software settings.
1.
Turn on the system and change the necessary BIOS settings, if any.

When using PCI cards on shared slots, ensure that the drivers support
“Share IRQ” or that the cards do not need IRQ assignments. Otherwise,
conflicts will arise between the two PCI groups, making the system
unstable and the card inoperable.

Jumpers
Clear RTC RAM (CLRTC)
This jumper allows you to clear the Real Time Clock (RTC) RAM in
CMOS. You can clear the CMOS memory of date, time, and system
setup parameters by erasing the CMOS RTC RAM data. The onboard
button cell battery powers the RAM data in CMOS, which include
system setup information such as system passwords.
To erase the RTC RAM:
1.
Turn OFF the computer and unplug the power cord.
2.
Remove the onboard battery.
3.
Move the jumper cap from pins 1-2 (default) to pins 2-3. Keep the
cap on pins 2-3 for about 5~10 seconds, then move the cap back to
pins 1-2.
4.
Re-install the battery.
5.
Plug the power cord and turn ON the computer.
6.
Hold down the <Del> key during the boot process and enter BIOS
setup to re-enter data.
Except when clearing the RTC RAM, never remove the cap on CLRTC
jumper default position. Removing the cap will cause system boot failure!

IDE connectors (40-1 pin PRI_IDE, SEC_IDE)
These connectors are for Ultra DMA 133/100/66 signal cables. The
Ultra DMA 133/100/66 signal cable has three connectors: a blue
connector for the primary IDE connector on the motherboard, a black
connector for an Ultra DMA 133/100/66 IDE slave device (optical
drive/hard disk drive), and a gray connector for an Ultra DMA 133/
100/66 IDE master device (hard disk drive). If you install two hard disk
drives, you must configure the second drive as a slave device by setting
its jumper accordingly. Refer to the hard disk documentation for the
jumper settings.
•
The Pin 20 on the IDE connector is removed to match the covered
hole on the Ultra DMA cable connector. This prevents incorrect
insertion when you connect the IDE cable.

BIOS setup program
This motherboard supports a programmable Low-Pin Count (LPC) chip that
you can update using the provided utility described in section “2.1
Managing and updating your BIOS.”
Use the BIOS Setup program when you are installing a motherboard,
reconfiguring your system, or prompted to “Run Setup”. This section
explains how to configure your system using this utility.
Even if you are not prompted to use the Setup program, you can change
the configuration of your computer in the future. For example, you can
enable the security password feature or change the power management
settings. This requires you to reconfigure your system using the BIOS
Setup program so that the computer can recognize these changes and
record them in the CMOS RAM of the LPC chip.
The LPC chip on the motherboard stores the Setup utility. When you start
up the computer, the system provides you with the opportunity to run this
program. Press <Del> during the Power-On Self-Test (POST) to enter the
Setup utility; otherwise, POST continues with its test routines.
If you wish to enter Setup after POST, restart the system by pressing
<Ctrl+Alt+Delete>, or by pressing the reset button on the system chassis.
You can also restart by turning the system off and then back on. Do this
last option only if the first two failed.
The Setup program is designed to make it as easy to use as possible. Being
a menu-driven program, it lets you scroll through the various sub-menus
and make your selections from the available options using the navigation
keys.
