Recommended memory congurations

Chapter 1

1-10

Chapter 1: Product introduction

Memory congurations

You may install 1GB, 2GB, 4GB, and 8GB 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.

• Always install DIMMs with the same CAS latency. For optimal compatibility, we
recommend that you install memory modules of the same version or date code (D/C)
from the same vendor. Check with the retailer to get the correct memory modules.

• Memory modules with memory frequency higher than 2133MHz and their
corresponding timing or the loaded XMP prole is not the JEDEC memory standard.

The stability and compatibility of the memory modules depend on the CPU’s
capabilities and other installed devices.

• Due to the CPU spec., AMD AM3 100 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:

a) Use a maximum of 3GB system memory if you are using a 32-bit Windows OS.Use a maximum of 3GB system memory if you are using a 32-bit Windows OS.

b) Install a 64-bit Windows OS when you want to install 4GB or more on theInstall a 64-bit Windows OS when you want to install 4GB or more on thenstall a 64-bit Windows OS when you want to install 4GB or more on the

motherboard.

c) 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 lesssupport DIMMs made up of 512Mb (64MB) chips or less 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 DetectThe 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 3.4 Ai Tweaker menu for manual memory
frequency adjustment.

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

memory load (4 DIMMs) or overclocking condition.

1.2.7 Jumpers

1. Clear RTC RAM (3-pin 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 re-enter
data.

Chapter 1

1-26

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 the CMOS clearance, 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 C.P.R. (CPU Parameter Recall) feature.
Shut down and reboot the system so the BIOS can automatically reset parameter
settings to default values.

• Due to the chipset behavior, AC power off is required to enable C.P.R. function. You
must turn off and on the power supply or unplug and plug the power cord before
rebooting the system.

The new ASUS UEFI BIOS is a Unied Extensible Interface that complies with UEFI

architecture, offering a user-friendly interface that goes beyond the traditional keyboard-

only BIOS controls to enable a more exible and convenient mouse input. You can easily

navigate the new UEFI BIOS with the same smoothness as your operating system. The

term “BIOS” in this user manual refers to “UEFI BIOS” unless otherwise specied.

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
optimal performance. DO 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 BIOS settings may result to instability or boot failure. We strongly

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