2.3 System memory

2.3.1 Overview

The motherboard comes with eight fully-buffered DIMM (FB-DIMM) sockets to
support 240-pin FB-DIMM modules. An FB-DIMM module has a different pin-out
from DDR2 DIMMs so you cannot install DDR2 DIMMs on an FB-DIMM socket.
Note that an FB-DIMM socket has an Advanced Memory Buffer (AMB) chip that
allows memory-to-CPU connection at gigabit speed.

The gure illustrates the location of the FB-DIMM sockets:

2.3.2 Memorycongurations

You may install 512 MB, 1 GB, 2 GB, and 4 GB registered ECC FB-DIMMs into the

DIMM sockets.

• For optimum compatibility, we recommend that you obtain memory modules

from the same vendor. Refer to the Qualied Vendors List on the ASUS

web site.

• This motherboard does not support memory modules made up of 128 Mb
chips x16 memory modules.

• If you are installing only one memory module, install into the white socket
labeled DIMM_00. Installing into any other socket will not work.

Mode as

[Mirror]), Branch 1 contains a replicate copy of the data in Branch 0. The

DIMMs must cover the same slot position on both branches. DIMMs that cover a

slot position must be identical with respect to size, speed, and organization. DIMMs
within a slot position must match each other, but aren’t required to match adjacent

slot positions.

And the total memories size will be the half of all installed memories.

Memory Sparing :

At conguration time, a DIMM rank is set aside to replace a defective DIMM rank.

When the error rate for a failing DIMM rank reaches a pre-determined threshold,
the memory sparing function will issue an interrupt and initiate a spare copy. At the
completion of the copy, the failing DIMM rank is disabled and the “spared” DIMM
rank will be used in its place. Refer to

5.4.2ChipsetConguration

and congure

the options of

Branch 0 Rank Sparing

to enable the memory sparing functions.

And the default BIOS setting is disabled.

• Each branch contains its own sparing engine and can be enabled or
disabled separately.

• This motherboard does not support rank sparing across branches.

• This motherboard does not support rank sparing when in mirror mode.

• The DIMM rank with the largest size will be assigned as spare rank. Data
can only be copied from a smaller sized rank to a larger sized one.

• A DIMM can contain only one or two ranks. To support sparing function, a
DIMM channel should contain at least two ranks.

• When sparing function is enabled, the usable memory size will reduce then
size of the spare ranks.

Except when clearing the RTC RAM, never remove the cap on CLRTC jumper
default position. Removing the cap will cause system boot failure!

4.2 Jumpers

1. Clear RTC RAM (CLRTC1)

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. Reinstall 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.

5.2 BIOS setup program

This motherboard supports a programmable Low-Pin Count (LPC) chip that you
can update using the provided utility described in section

5.1 Managing and

updating your BIOS

.

Use the BIOS Setup program when you are installing a motherboard, reconguring
your system, or prompted to “Run Setup.” This section explains how to congure

your system using this utility.

Even if you are not prompted to use the Setup program, you can change the

conguration 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 recongure 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 rst 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.

• 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 Default Settings

item under the

Exit Menu. See section

5.8 Exit Menu

.

• The BIOS setup screens shown in this section are for reference purposes
only, and may not exactly match what you see on your screen.

• Visit the ASUS website (www.asus.com) to download the latest BIOS le for

this motherboard.
