KFSN4-DRE CPU Socket 1207

CPU2

CPU1

The motherboard comes with a surface mount Socket F designed for the AMD®
Opteron® 2000 Series CPU in the Land Grid Array (LGA) package.

•

Upon purchase of the motherboard, make sure that the PnP cap is on
the socket and the socket contacts are not bent. Contact your retailer
immediately if the PnP cap is missing, or if you see any damage to the PnP

cap/socket contacts/motherboard components. ASUS will shoulder the cost
of repair only if the damage is shipment/transit-related.

•

Keep the cap after installing the motherboard. ASUS will process Return

Merchandise Authorization (RMA) requests only if the motherboard comes

with the cap on the CPU socket.

• Ensure to install identical CPUs to the system. DO NOT mix Quad-core and
Dual-core CPUs.

• When you install varying stepping and speed CPUs to the system, the

faster CPU downgrades and runs the speed as the slower one.

• The product warranty does not cover damage to the socket contacts

resulting from incorrect CPU installation/removal, or misplacement/loss/

incorrect removal of the PnP cap.

2.2.1 Installing the CPU

To install a CPU:

1. Locate the CPU socket on the motherboard.

• Before installing the CPU, make sure that the socket box is facing towards

you and the load lever is on your left.

• When installing only one CPU, install it in the CPU1 socket, or the CPU

warning LED will light.

Chapter 2: Hardware setup2-4

2. Press the load lever with your thumb (A), then move it to the left (B) until it is

released from the retention tab.

2.3 System memory

2.3.1 Overview

The motherboard comes with sixteen (16) 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 gure illustrates the location of the DDR2 DIMM sockets:

Chapter 2: Hardware setup2-8

2.3.2 MemoryCongurations

You may install 256 MB, 512 MB, 1 GB, 2, or 4 GB registered ECC DDR2 DIMMs
into the DIMM sockets using the memory congurations in this section.

•

For dual-channel conguration, the total size of memory module(s) installed

per channel must be the same for better performance.
Single CPU:

DIMM_A1=DIMM_A2=DIMM_B1=DIMM_B2;
DIMM_A3=DIMM_A4=DIMM_B3=DIMM_B4

Dual CPU:

DIMM_A1=DIMM_A2=DIMM_B1=DIMM_B2=
DIMM_C1=DIMM_C2 =DIMM_D1=DIMM_D2;

DIMM_A3=DIMM_A4=DIMM_B3=DIMM_B4=

DIMM_C3=DIMM_C4 =DIMM_D3=DIMM_D4

•

Always install DIMMs with the same CAS latency. For optimum
compatibility, it is recommended that you obtain memory modules from the
same vendor.

2.3.3 Installing a DIMM

Make sure to unplug the power supply before adding or removing DIMMs or
other system components. Failure to do so may cause severe damage to both
the motherboard and the components.

To install a DIMM:

1. Unlock a DIMM socket by
pressing the retaining clips
outward.

2. Align a DIMM on the socket

such that the notch on the
DIMM matches the break on the
socket.

3. Firmly insert the DIMM into the
socket until the retaining clips
snap back in place and the
DIMM is properly seated.

• A DDR2 DIMM is keyed with a notch so that it ts in only one direction. Do not

force a DIMM into a socket to avoid damaging the DIMM.

• The DDR2 DIMM sockets do not support DDR DIMMs. DO NOT install
DDR DIMMs to the DDR2 DIMM sockets.

2.3.4 Removing a DIMM

Follow these steps to remove a DIMM.

5.2 BIOS setup program

This motherboard supports a programmable Serial Peripheral Interface (SPI) 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

SPI chip.

The SPI 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 Setup Defaults 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.

Chapter 6

This chapter provides instructions for

setting up, creating and conguring

RAID sets using the available utilities.

RAIDConguration

2-

6.1 Setting up RAID

The system comes with the following RAID solutions:

®

• The NVIDIA

RAID controller that allows you to congure RAID 0 and RAID 1 with SATA

hard disk drives.

6.1.1 RAIDdenitions

(Data striping)

RAID 0

data in parallel, interleaved stacks. Two hard disks perform the same work as a
single drive but at a sustained data transfer rate, double that of a single disk alone,
thus improving data access and storage. Use of two new identical hard disk drives
is required for this setup.

(Data mirroring)

RAID 1

drive to a second drive. If one drive fails, the disk array management software
directs all applications to the surviving drive as it contains a complete copy of

the data in the other drive. This RAID conguration provides data protection and

increases fault tolerance to the entire system. Use two new drives or use an
existing drive and a new drive for this setup. The new drive must be of the same

size or larger than the existing drive.

6.1.2 Installing hard disk drives

nForce Professional 2200 chipset comes with a built-in SATA

optimizes two identical hard disk drives to read and write

copies and maintains an identical image of data from one

If you want to boot the system from a hard disk drive included in a created RAID

set, copy rst the RAID driver from the support CD to a oppy disk before you
install an operating system to the selected hard disk drive. Refer to Chapter 7

for details.

The motherboard supports Serial ATA (both models) for RAID set conguration. For

optimal performance, install identical drives of the same model and capacity when
creating a disk array.

To install the SATA hard disks for RAID conguration:

1. Install the SATA hard disks into the drive bays following the instructions in the
system user guide.

2. Connect a SATA signal cable to the signal connector at the back of each drive

and to the SATA connector on the motherboard.

3. Connect a SATA power cable to the power connector on each drive.

6.1.3 RAIDcongurationutility

You can create a RAID set using the utility embedded in each RAID controller. For
example, you can use the NVIDIA® RAID Utility if you installed SATA hard disk
drives to the SATA connectors supported by the NVIDIA® nForce Professional

2200 chip. Refer to the succeeding sections for details on how to enter the RAID
conguration utility.
