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.

2.4 System memory

2.4.1 Overview

The 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:

Chapter 2

Recommended memory congurations

One DIMM:

When installing one memory module, we suggest that you install it on A1 slot.

Two DIMMs (dual-channel operation):

Four DIMMs (dual-channel operation):

2-10 Chapter 2: Hardware information

2.4.2 Memory congurations

You may install 512MB, 1GB, 2GB and 4GB unbuffered ECC and 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 conguration. Any excess
memory from the higher-sized channel is then mapped for single-channel operation.

• We recommend that you install the memory modules from the blue slots for better
overclocking capability.

• 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 CPU spec., AMD AM3 100 and 200 series CPUs support up to DDR3

1066MHz. With ASUS design, this motherboard can support up to DDR3 1333MHz.

• When overclocking, some AMD CPU models may not support DDR3 1600 or higher
frequency DIMMs.

• 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 on the

motherboard.
For more details, refer to the Microsoft® support site at
http://support.microsoft.com/kb/929605/en-us.

• This motherboard does not support DIMMs made up of 512Mb (64MB) chips or less
(Memory chip capacity counts in Megabit, 8 Megabit/Mb = 1 Megabyte/MB).

• The default memory operation frequency is dependent 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. To operate at the vendor-marked
or at a higher frequency, refer to section
frequency adjustment.

• For system stability, use a more efcient memory cooling system to support a full

memory load (4 DIMMs) or overclocking condition.

2.5 Expansion slots

In the future, you may need to install expansion cards. The following subsections describe the
slots and the expansion cards that they support.

Ensure to unplug the power cord before adding or removing expansion cards. Failure to do
so may cause you physical injury and damage motherboard components.

2.5.1 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.

2.5.2 Conguring an expansion card

After installing the expansion card, congure it by adjusting the software settings.

1. Turn on the system and change the necessary BIOS settings, if any. See Chapter 3 for
information on BIOS setup.

2. Assign an IRQ to the card. Refer to the tables on the next page.

3. Install the software drivers for the expansion card.

Chapter 2

When using PCI cards on shared slots, ensure that the drivers support “Share IRQ” or that

the cards do not need IRQ assignments. Otherwise, conicts will arise between the two PCI

groups, making the system unstable and the card inoperable. Refer to the table on the next
page for details.

2.6 Onboard switches

Onboard switches allow you to ne-tune performance when working on a bare or open-case

system. This is ideal for overclockers and gamers who continually change settings to enhance
system performance.

1. MemOK! switch

Installing DIMMs that are incompatible with the motherboard may cause system
boot failure, and the DRAM_LED near the MemOK! switch lights continuously. Press
and hold the MemOK! switch until the DRAM_LED starts blinking to begin automatic
memory compatibility tuning for successful boot.

Chapter 2

• Refer to section

• The DRAM_LED also lights when the DIMM is not properly installed. Turn off the
system and reinstall the DIMM before using the MemOK! function.

• The MemOK! switch does not function under Windows

• During the tuning process, the system loads and tests failsafe memory settings. It
takes about 30 seconds for the system to test one set of failsafe settings. If the test
fails, the system reboots and test the next set of failsafe settings. The blinking speed
of the DRAM_LED increases, indicating different test processes.

• Due to memory tuning requirement, the system automatically reboots when each
timing set is tested. If the installed DIMMs still fail to boot after the whole tuning
process, the DRAM_LED lights continuously. Replace the DIMMs with ones

recommended in the Memory QVL (Qualied Vendors Lists) in this user manual or on

the ASUS website at www.asus.com.

• If you turn off the computer and replace DIMMs during the tuning process, the system
continues memory tuning after turning on the computer. To stop memory tuning, turn
off the computer and unplug the power cord for about 5–10 seconds.

• If your system fail to boot due to BIOS overclocking, press the MemOK! switch to boot
and load BIOS default settings. A messgae will appear during POST reminding you
that the BIOS has been restored to its default settings.

• We recommend that you download and update to the latest BIOS version from the
ASUS website at www.asus.com after using the MemOK! function.

Chapter 3: BIOS setup

3.1 Knowing BIOS

BIOS (Basic Input and Output System) stores system hardware settings such as storage

device conguration, overclocking settings, advanced power management, and boot device
conguration that are needed for system startup in the motherboard CMOS. In normal

circumstances, the default BIOS settings apply to most conditions to ensure optimum
performance. We recommend that you not change the default BIOS settings except in
the following circumstances:

• An error message appears on the screen during the system bootup and requests you to
run the BIOS Setup.

• You have installed a new system component that requires further BIOS settings or
update.

Inappropriate settings of the BIOS may result to instability or failure to boot. We strongly

recommend that you change the BIOS settings only with the help of a trained service
personnel.

3.2 Updating BIOS

The ASUS website publishes the latest BIOS versions to provide enhancements on system
stability, compatibility, or performance. However, BIOS updating is potentially risky. If there
is no problem using the current version of BIOS, DO NOT manually update the BIOS.
Inappropriate BIOS updating may result in the system’s failure to boot. Carefully follow the
instructions of this chapter to update your BIOS if necessary.
