Ensure that you use only AMD-certied heatsink and fan assembly.
To install the CPU heatsink and fan:
1. Place the heatsink on top of the installed CPU, ensuring that the heatsink ts 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.

1.7 System memory
1.7.1 Overview
This motherboard comes with four Double Data Rate 3 (DDR3) Dual Inline Memory Modules
(DIMM) sockets. A DDR3 module has the same physical dimensions as a DDR2 DIMM but
is notched differently to prevent installation on a DDR2 DIMM socket. DDR3 modules are
developed for better performance with less power consumption. The gure illustrates the
location of the DDR3 DIMM sockets:
Channel Sockets
Channel A DIMM_A1 and DIMM_A2
Channel B DIMM_B1 and DIMM_B2
Chapter 1: Product introduction1-10
1.7.2 Memory congurations
You may install 512MB, 1GB, 2GB, and 4GB unbuffered non-ECC DDR3 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 conguration. 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.
• We recommend that you install the memory modules from the blue slots for better
overclocking capability.
• Due to the CPU specication, AMD
1066MHz. With ASUS design, this motherboard can support up to DDR3 1333MHz.
• When overclocking, some AMD CPUs may not support DDR3 1600MHz or higher
frequency DIMMs.
• Due to the memory address limitation on 32-bit Windows
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:
- Install a maximum of 3GB system memory if you are using a 32-bit Windows
OS.
- Use a 64-bit Windows® OS if 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.

1.8 Expansion slots
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 rmly 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 Conguring an expansion card
After installing the expansion card, congure 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, conicts will arise between the two PCI
groups, making the system unstable and the card inoperable.
1.8.3 PCI slots
The PCI slots support cards such as a LAN card, SCSI card, USB card, and other cards that
comply with PCI specications.
1.8.4 PCI Express x1 slots
This motherboard supports PCI Express x1 network cards, SCSI cards, and other cards that
comply with the PCI Express specications.
1.8.5 PCI Express x16 slot
This motherboard supports a PCI Express x16 graphics card that comply with the PCI
Express specications.

1. 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
data.
<Del> key during the boot process and enter BIOS setup to reenter
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.

We recommend that you use an ATX 12V Specication 2.0-compliant power supply unit
(PSU) with a minimum of 300W power rating. This PSU type has 24-pin and 4-pin power
plugs.
•
If you intend to use a PSU with 20-pin and 4-pin power plugs, ensure that the 20-pin
power plug can provide at least 15 A on +12 V and that the PSU has a minimum power
rating of 300W. The system may become unstable or may not boot up if the power is
inadequate.
•
DO NOT forget to connect the 4-pin ATX12V power plug. Otherwise, the system will not
boot up.
• We recommend that you use a PSU with higher power output when conguring a
system with more power-consuming devices or when you intend to install additional
devices. The system may become unstable or may not boot up if the power is
inadequate.
