478-pin surface mount ZIF socket. The processor with 1MB/512KB L2 cache
includes a 800/533 MHz system bus and features the Intel HyperThreading Technology and new power design that allow up to 3.4+GHz
core frequencies.
Dual-channel DDR400 memory support
Employing the dual-channel DDR memory architecture, the motherboard
provides a solution that doubles the system memory bandwidth to boost
system performance. The motherboard supports up to 4GB of system
memory using PC3200/2700/2100 ECC or non-ECC DDR DIMMs to
deliver up to 6.4GB/s data transfer rate for the latest 3D graphics,
multimedia, and Internet applications.
Serial ATA technology
The motherboard supports the new Serial ATA technology through the
SATA interfaces and the Intel® 6300ESB ICH and Promise® PDC20319
controllers onboard. The SATA specification allows for thinner, more
flexible cables with lower pin count, reduced voltage requirement, and up
to 150MB/s data transfer rate.
Multi-RAID solution
The motherboard has the Promise® PDC20319 controller to support multiRAID solution using Serial ATA/150 hard disks. The RAID0 (striping),
RAID1 (mirroring), and RAID 0+1 provide a cost-effective highperformance solution for added system performance and reliability.
Gigabit LAN solution
The Intel® 82547GI Gigabit Ethernet controller allows full-duplex Gigabit
performance on LAN on Motherboard (LOM) applications through the
Communication Streaming Architecture (CSA). Instead of connecting to
the PCI bus, the controller connects to the dedicated CSA bus on the
Memory Controller Hub (MCH) thus reducing the PCI bottlenecks by
freeing the PCI bus for other I/O operations.

BIOS Setup program
This motherboard supports a programmable firmware 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 may want to
change the configuration of your computer in the future. For example, you
may want to 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 firmware hub.
The firmware hub 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. It is
a menu-driven program, which means you can 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 “4.7 Exit Menu.”
1. The BIOS setup screens shown in this chapter are for reference
purposes only, and may not exactly match what you see on your
screen.
2. Visit the ASUS website (www.asus.com) to download the latest
product and BIOS information.
