• Due to chipset limitation, Intel® Pentium® D 820 processors work
only in single-core CPU mode.

• Due to chipset limitation, dual-core processors cannot support the
Intel® EIST, TM2, and C1E functions.

•

Install a chassis fan with at least a speed of 2400 rpm and 8 CFM
turnrate when using a dual-core CPU to ensure system stability.
Overheating can permanently damage the system and/or CPU.

• Install an additional chassis fan to ensure better air flow when
overclocking.

• 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 LGA775 socket.

• 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.

Installing the CPU heatsink and fan

Installing the CPU heatsink and fanInstalling the CPU heatsink and fan

Intel® LGA775 processors require a specially designed heatsink and fan
assembly to ensure optimum thermal condition and performance.

•

When you buy a boxed Intel® processor, the package includes the
CPU fan and heatsink assembly. If you buy a CPU separately, make
sure that you use only Intel®-certified multi-directional heatsink and
fan.

•

Your Intel® LGA775 processor heatsink and fan assembly comes in a
push-pin design and requires no tool to install.

•

If you purchased a separate CPU heatsink and fan assembly, make
sure that you have properly applied Thermal Interface Material to the
CPU heatsink or CPU before you install the heatsink and fan
assembly.

Make sure that you have installed the motherboard to the chassis before
you install the CPU fan and heatsink assembly.

To install the CPU heatsink and fan:

1. Place the heatsink on top of
the installed CPU, making sure
that the four fasteners match
the holes on the motherboard.

Orient the heatsink and fan
assembly such that the CPU
fan cable is closest to the
CPU fan connector.

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 configurationsMemory configurations

You may install 256 MB, 512 MB, 1 GB and 2 GB unbuffered non-ECC DDR2
DIMMs into the DIMM sockets.

• 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, it is recommended that you obtain memory modules
from the same vendor. Refer to the DDR2 Qualified Vendors List on
the next page for details.

• Due to chipset resource allocation, the system may detect less than
8 GB system memory when you installed four 2 GB DDR2 memory
modules.

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

1. Turn on the system and change the necessary BIOS settings, if any.
See Chapter 4 for information on BIOS setup.

2. Assign an IRQ to the card. Refer to the tables on the next page.

3. Install the software drivers for the expansion card.

When using PCI cards on shared slots, ensure that the drivers support
“Share IRQ” or that the cards do not need IRQ assignments. Otherwise,
conflicts will arise between the two PCI groups, making the system
unstable and the card inoperable. Refer to the table on the next page for
details.

SLI-ready PCI Express x16 graphic
cards that comply with the PCI
Express specifications. The figure
shows a graphics card installed on
the PCI Express x16 slot.

See Chapter 6 for details on the SLI
technology feature.

• Install a rear chassis fan to either the chassis (CHA_FAN1) or
NorthBridge (NB_FAN) connectors when using two graphics cards
for better thermal environment. See page 2-33 for details.

• Connect the EZ Plug™ when using two graphics cards and a 20-pin
ATX power supply.

• In Single Card mode, only the PCI Express blue slot can be used for
PCI Express x16 graphics cards.

• In SLI mode, the PCI Express x16 slots work at the bandwidth of PCI
Express x8. The combined bandwidth of these maintain the
bandwidth of PCI Express x16.

• See the table below for possible PCI Express card configurations.

Clear RTC RAM (CLRTC)Clear RTC RAM (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. 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. Re-install 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.

Except when clearing the RTC RAM, never remove the cap on CLRTC
jumper default 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.

These connectors are for Ultra DMA 133/100/66 signal cables. The

Ultra DMA 133/100/66 signal cable has three connectors: a blue
connector for the primary IDE connector on the motherboard, a black
connector for an Ultra DMA 133/100/66 IDE slave device (optical
drive/hard disk drive), and a gray connector for an Ultra DMA 133/
100/66 IDE master device (hard disk drive). If you install two hard disk
drives, you must configure the second drive as a slave device by setting
its jumper accordingly. Refer to the hard disk documentation for the
jumper settings.

• Pin 20 on the IDE connector is removed to match the covered hole
on the Ultra DMA cable connector. This prevents incorrect insertion
when you connect the IDE cable.

• Use the 80-conductor IDE cable for Ultra DMA 100/66 IDE devices.

• These connectors support RAID 0, RAID 1, RAID 0+1, RAID 5 and
JBOD that spans across the Serial ATA drives.

•

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 400 W.

• Do not forget to connect the 4-pin ATX +12 V power plug;
otherwise, the system will not boot.

•

When using two graphics cards, do not forget to connect the 4-pin
ATX +12 V power plug to the EZ Plug™; otherwise, the system will
be unstable. See page 6-6 for details.

• To support an Intel

®

Dual-Core CPU Extreme Edition up to 3.2 GHz,
make sure that the PSU can provide at least 16 A and 19 A peak on
the +12V_2 lead. Refer to the vendors list on Table 1 for details.

• 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. See Table 2 for details.

3.1 Starting up for the first time

1. After making all the connections, replace the system case cover.

2. Be sure that all switches are off.

3. Connect the power cord to the power connector at the back of the
system chassis.

4. Connect the power cord to a power outlet that is equipped with a
surge protector.

5. Turn on the devices in the following order:
a. Monitor
b. External SCSI devices (starting with the last device on the chain)
c. System power

6. After applying power, the system power LED on the system front
panel case lights up. For systems with ATX power supplies, the system
LED lights up when you press the ATX power button. If your monitor
complies with “green” standards or if it has a “power standby”
feature, the monitor LED may light up or switch between orange and
green after the system LED turns on.

The system then runs the power-on self tests or POST. While the
tests are running, the BIOS beeps or additional messages appear on
the screen. If you do not see anything within 30 seconds from the
time you turned on the power, the system may have failed a power-on
test. Check the jumper settings and connections or call your retailer
for assistance.

7. At power on, hold down the <Delete> key to enter the BIOS Setup.
Follow the instructions in Chapter 4.

4.2 BIOS setup program

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

“

4.1

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
Default SettingsDefault Settings

Default Settings item under the Exit Menu. See section “4.7 Exit

Default SettingsDefault Settings
Menu.”
