Central Processing Unit (CPU)
The motherboard comes with an AM2+ / AM2 socket designed for Phenom™ II /
Athlon™ II / Phenom™ / Athlon™/ Sempron™ family processors (AM3 / AM2+ / AM2).
The AM3/AM2/AM2+ socket has a different pinout from the 940-pin socket designed for the
AMD Opteron™ processor. Use a CPU that is designed for the AM3/AM2/AM2+ socket.
1.6.1
Installing the CPU
To install a CPU:
1.
Locate the CPU socket on the motherboard.
2.
Unlock the socket by pressing the lever
sideways, then lift it up to a 90º angle.
Socket lever
Make sure that the socket lever is lifted up to
a 90º angle; otherwise, the CPU will 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.

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.
6.
Install a CPU heatsink and fan following
the instructions that came with the heatsink
package.
7.
Connect the CPU fan cable to the CPU_FAN connector on the motherboard.
Do not forget to connect the CPU fan connector! Hardware monitoring errors can occur if
you fail to plug this connector.

1.6.2
Installing the heatsink and fan
Ensure that you use only AMD-certified heatsink and fan assembly.
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, ensure 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.
2.
Attach one end of the retention bracket to the retention module base.

3.
Align the other end of the retention bracket to the retention module base. A clicking
sound denotes that the retention bracket is in place.
Ensure 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.
5.
When the fan and heatsink assembly is in place, connect the CPU fan cable to the
connector on the motherboard labeled CPU_FAN.
Do not forget to connect the CPU fan connector! Hardware monitoring errors can occur if
you fail to plug this connector.

System memory
1.7.1
Overview
The motherboard comes with four Double Data Rate 2 (DDR2) Dual Inline Memory Modules
(DIMM) sockets. A DDR2 module has the same physical dimensions as a DDR DIMM but
has a 240-pin footprint compared to the 184-pin DDR DIMM. DDR2 DIMMs are notched
differently to prevent installation on a DDR DIMM socket. The figure illustrates the location of
the DDR2 DIMM sockets:

1.7.2
Memory configurations
You may install 512MB, 1GB, 2GB, and 4GB unbuffered ECC/non-ECC DDR2 DIMMs into
the DIMM sockets.
• You may install varying memory sizes in Channel A and Channel B. The system maps
the total size of the lower-sized channel for the dual-channel configuration. Any excess
memory from the higher-sized channel is then mapped for single-channel operation.
• Always install DIMMs with the same CAS latency. For optimum compatibility, we
recommend that you obtain memory modules from the same vendor.
• Due to the memory address limitation on 32-bit Windows® OS, when you install 4GB
or more memory on the motherboard, the actual usable memory for the OS can be
about 3GB or less. For effective use of memory, we recommend that you do any of the
following:
-��������������������������������������������������������������������
Use a maximum of 3GB system memory if you are using a 32-bit Windows® OS.
-
Install a 64-bit �������
Windows® OS when you want to install 4GB or more memory on the motherboard.
• This motherboard does not support DIMMs made up of 256 megabits (Mb) chips or less.
The motherboard supports up to 16GB memory modules on Windows® XP Professional x64
and Vista x64 editions. You may install a maximum of 4 GB DIMMs on each slot.

Chapter 1: Product introduction
7/6/09 9:09:56 AM
• The default DIMM frequency depends on its Serial Presence Detect (SPD), which is the
standard way of accessing information from a memory module. Under the default state,
some memory modules for overclocking may operate at a lower frequency than the
vendor-marked value.
• The memory modules may require a better cooling system to work stably under full
loading (4 DIMMs) or overclocking setting.
SS - Single-sided / DS - Double - sided
DIMM support:
• A*: Supports one module inserted into any slot as Single-channel memory configuration.
• B*: Supports one pair of modules inserted into either the blue or black slots as one pair of Dual-channel memory configuration.
• C*: Supports four modules inserted into both the blue and black slots as two pairs of Dual-channel memory configuration.

In the future, you may need to install expansion cards. The following sub‑sections describe
the slots and the expansion cards that they support.
Unplug the power cord before adding or removing expansion cards. Failure to do so may
cause you physical injury and damage motherboard components.
1.8.1
Installing an expansion card
To install an expansion card:
1.
Before installing the expansion card, read the documentation that came with it and
make the necessary hardware settings for the card.
2.
Remove the system unit cover (if your motherboard is already 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 it by adjusting the software settings.
1.
Turn on the system and change the necessary BIOS settings, if any. See Chapter 2 for
information on BIOS setup.
2.
Assign an IRQ to the card.
3.
Install the software drivers for the expansion card.
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.
1.8.3
PCI slots
1.8.4
PCI Express x1 slot
1.8.5
PCI Express x16 slot
The PCI slots support cards such as a LAN card, SCSI card, USB card, and other cards that
comply with PCI specifications.
This motherboard supports PCI Express x1 network cards, SCSI cards, and other cards that
comply with the PCI Express specifications.
This motherboard supports a PCI Express x16 graphics card that complies with the PCI
Express specifications.

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.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.
3.
Plug the power cord and turn ON the computer.
4.Hold down the <Del> key during the boot process and enter BIOS setup to
reenter data.
Except when clearing the RTC RAM, never remove the cap on CLRTC jumper default
position. Removing the cap will cause system boot failure!
• If the steps above do not help, remove the onboard battery and move the jumper again
to clear the CMOS RTC RAM data. After clearing the CMOS, reinstall the battery.
• You do not need to clear the RTC when the system hangs due to overclocking. For system failure due to overclocking, use the CPU Parameter Recall (C.P.R) feature. Shut down and reboot the system so the BIOS can automatically reset parameter settings to default values.

procedures:
•
Restart using the OS standard shut-down procedure.
•
Press <Ctrl>+<Alt>+<Del> simultaneously.
•
Press the reset button on the system chassis.
•
Press the power button to turn the system off then back on.
Using the power button, reset button, or the <Ctrl>+<Alt>+<Del> keys to force
reset from a running operating system can cause damage to your data or system. We
recommend to always shut-down the system properly from the operating system.
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.
• The default BIOS settings for this motherboard apply for most conditions to ensure
optimum performance. If the system becomes unstable after changing any BIOS
settings, load the default settings to ensure system compatibility and stability. Select the
Load Setup Defaults item under the Exit menu. See section “2.8 Exit menu”.
