MHz, 667 MHz or 533 MHz to meet the higher bandwidth requirements of the  
latest 3D graphics, multimedia, and Internet applications. The dual-channel DDR2  
architecture doubles the bandwidth of your system memory to boost system  
performance, eliminating bottlenecks with peak bandwidths of up to 10.7 GB/s.  
See pages 2-12 to 2-16 for details.  
1-2  
Chapter 1: Product introduction  
PCI Express™ interface  
The motherboard fully supports PCI Express, the latest I/O interconnect technology  
that speeds up the PCI bus. PCI Express features point-to-point serial  
interconnections between devices and allows higher clockspeeds by carrying data  
in packets. This high speed interface is software compatible with existing PCI  
specifications. See page 2-20 for details.  
Serial ATA I/II technology and SATA-On-The-Go  
The motherboard fully supports the Serial ATA II 3.0 Gb/s technology through the  
Serial ATA interfaces and the NVIDIA® NF590-SLI chipset. The Serial ATA 3 Gb/s  
specification provides twice the bandwidth of the current Serial ATA products with  
a host of new features, including Nativa Command Queueing (NCQ), and Power  
Management (PM) Implementation Algorithm. Serial ATA allows for thinner, more  
flexible cables with lower pin count and reduced voltage required. Leveraging  
these Serial ATA 3Gb/s features is the SATA-On-The-Go. Supported by the  
Silicon Image Sil3132 Serial ATA controller, external SATA ports on the rear panel  
I/O provide smart setup, hot-plug and support for up to 16 devices per port with  
port-multiplier functions. See pages 2-23 and 2-27 for details.  
Dual RAID solution  
Onboard RAID controllers provide the motherboard with dual-RAID functionality  
that allows you to select the best RAID solution using IDE or Serial ATA devices.  
The NVIDIA® NF590-SLI chipset allows RAID 0, RAID 1, RAID 0+1, RAID 5, and  
JBOD configuration for six SATA 3.0 Gb/s. See pages 2-27 and 5-24.  
The Silicon Image® 3132 controller supports two additional external Serial ATA  
3.0 Gb/s ports on the rear panel and allows RAID 0, RAID 1, RAID 0+1, RAID 5  
through port multiplier and JBOD configurations on these ports. See pages 2-23  
and 5-31 for details.  
IEEE 1394a support  
The IEEE 1394a interface provides high-speed and flexible PC connectivity to  
a wide range of peripherals and devices compliant to the IEEE 1394a standard.  
The IEEE 1394a interface allows up to 400 Mbps transfer rates through simple,  
low-cost, high-bandwidth asynchronous (real-time) data interfacing between  
computers, peripherals, and consumer electronic devices such as camcorders,  
VCRs, printers, TVs, and digital cameras. See pages 2-22 and 2-28 for details.  
ASUS Crosshair

System memory  
2.4.1  
Overview  
The motherboard comes with four 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 figure illustrates the location of the DDR2 DIMM sockets:

Memory configurations  
You may install 256 MB, 512 MB, 1 GB, and 2 GB unbuffered ECC/non-ECC  
DDR2 DIMMs into the DIMM sockets.  
If you installed Windows® XP 32-bit version operating system, we  
recommend that you install less than 3 GB of total memory. For Windows®  
XP 64-bit version operating system, the maxium support is 8 GB of total  
memory.  
For dual-channel configuration, the total size of memory module(s) installed  
per channel must be the same (DIMM_A1 + DIMM_A2 = DIMM_B1 +  
DIMM_B2).  
Always install DIMMs with the same CAS latency. For optimum  
compatibility, we recommend that you obtain memory modules from the  
same vendor. Refer to the DDR2 Qualified Vendors List on the next page  
for details.

Jumper  
Clear RTC RAM (CLRTC)  
This jumper allows you to enable the CLRTC switch. You can clear the  
CMOS memory of date, time, and system setup parameters by erasing the  
CMOS RTC RAM data. The onboard clr CMOS switch helps you easily to  
clear the system setup information such as system passwords. See page  
2-35 for details.  
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 to enable the  
CLRTC function.  
3. Press down the clr CMOS button and again to release it.  
4. Plug the power cord and turn ON the computer.  
5. Hold down the <Del> key during the boot process and enter BIOS setup  
to re-enter data.  
The clr CMOS button will not function until the jumper cap on CLRTC is moved  
to the ENABLE position. Removing the cap will cause system boot failure!

Make sure to re-enter your previous BIOS settings after you clear the  
CMOS.  
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.  
To prevent accidental pressing of the Clear CMOS switch, the CLRTC  
jumper default setting disables the switch.

CROSSHAIR ATX power connectors  
For a fully configured system, we recommend that you use a power supply  
unit (PSU) that complies with ATX 12 V Specification 2.0 (or later version)  
and provides a minimum power of 600 W.  
Do not forget to connect the 8-pin ATX +12 V power plug; otherwise, the  
system will not boot.  
To support an AMD® Dual-Core CPU,make sure that the PSU can provide  
at least 16 A and 19 A peak on the +12V_2 lead.  
Use of a PSU with a higher power output is recommended when configuring  
a system with more power-consuming devices. The system may become  
unstable or may not boot up if the power is inadequate.

BIOS setup program  
This motherboard supports a programmable Low-Pin Count (LPC) chip that you  
can update using the provided utility described in section “4.1 Managing and  
updating your BIOS.”  
Use the BIOS Setup program when you are installing a motherboard, reconfiguring  
your system, or prompted to“Run Setup.” This section explains how to configure  
your system using this utility.  
Even if you are not prompted to use the Setup program, you can change the  
configuration 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 reconfigure 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 first 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 “4.9 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 file for  
this motherboard.

RAID configurations  
The motherboard comes with the Silicon Image Sil3132 and the NVIDIA® nForce™  
590- SLI Southbridge RAID controllers that allow you to configure Serial ATA  
hard disk drives as RAID sets. The motherboard supports the following RAID  
configurations.  
RAID 0 (Data striping) optimizes two identical hard disk drives to read and write  
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.  
RAID 1 (Data mirroring) copies and maintains an identical image of data from one  
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 configuration 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.  
RAID 0+1 is data striping and data mirroring combined without parity (redundancy  
data) having to be calculated and written. With the RAID 0+1 configuration you get  
all the benefits of both RAID 0 and RAID 1 configurations. Use four new hard disk  
drives or use an existing drive and three new drives for this setup.  
RAID 5 stripes both data and parity information across three or more hard  
disk drives. Among the advantages of RAID 5 configuration include better  
HDD performance, fault tolerance, and higher storage capacity. The RAID  
5 configuration is best suited for transaction processing, relational database  
applications, enterprise resource planning, and other business systems. Use a  
minimum of three identical hard disk drives for this setup.  
RAID 10 is a striped configuration with each stripe a RAID 1 array of drives. It  
combines the features of both RAID 1 and RAID 0. Fault tolerance is provided  
through mirroring while adding performance through striping. This offers higher  
performance than a RAID 1 configuration but at a much higher cost. A minimum of  
four hard disk drives is required for this setup.  
JBOD (Spanning) stands for Just a Bunch of Disks and refers to hard disk drives  
that are not yet configured as a RAID set. This configuration stores the same  
data redundantly on multiple disks that appear as a single disk on the operating  
system. Spanning does not deliver any advantage over using separate disks  
independently and does not provide fault tolerance or other RAID performance  
benefits.  
ꢃ-2ꢂ  
Chapter 5: Software support  
If you want to boot the system from a hard disk drive included in a RAID set,  
copy first the RAID driver from the support DVD to a floppy disk before you  
install an operating system to a selected hard disk drive. Refer to section “5.5  
Creating a RAID driver disk” for details.  
5.4.1  
NVIDIA® RAID configurations  
The motherboard includes a high performance SATA RAID controller integrated in  
the NVIDIA® nForce™ 590-SLI southbridge chipset. It supports RAID 0, RAID 1,  
RAID 0+1, RAID 5 and JBOD for six independent Serial ATA channels.  
Installing Serial ATA (SATA) hard disks  
The motherboard supports Ultra DMA 133/100/66 and Serial ATA hard disk drives.  
For optimal performance, install identical drives of the same model and capacity  
when creating a disk array.  
To install the SATA hard disks for a RAID configuration:  
1.  
2.  
3.  
Install the SATA hard disks into the drive bays.  
Connect the SATA signal cables.  
Connect a SATA power cable to the power connector on each drive.  
Refer to the RAID controllers user manual in the motherboard support DVD for  
detailed information on RAID configurations. See section “5.2.5 Manuals menu.”  
Setting the BIOS RAID items  
After installing the hard disk drives, make sure to set the necessary RAID items in  
the BIOS before setting your RAID configuration.  
To set the BIOS RAID items:  
1.  
2.  
3.  
Boot the system and press <Del> during the Power-On Self-Test (POST) to  
enter the BIOS Setup Utility.  
Enable the RAID Enabled item in the BIOS. See section “4.5.4 Onboard  
Device Configuration > Serial-ATA Configuration” for details.  
Select and enable the IDE or SATA drive(s) that you want to configure  
as RAID. See section “4.5.4 Onboard Device Configuration > Serial-ATA  
Configuration” for details.  
4.  
Save your changes and Exit Setup.  
Make sure to re-enter your NVRAID settings after the CMOS is cleared;  
otherwise, the system will not recognize your RAID setup.  
For detailed descriptions on the NVIDIA® RAID configuration, refer to the  
“NVIDIA® RAID User’s Manual” found in your motherboard support DVD.  
When using Windows 2000 operating system, make sure to install the  
Windows 2000 Service Pack 4 or later versions.
