2.4.3 Installing a DIMM

Unplug the power supply before adding or removing DIMMs or other system components. Failure to do so can 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.

2.4.4 Removing a DIMM

To remove a DIMM:

1. Simultaneously press the retaining clips outward to unlock the DIMM.

2.5 Expansion slots

In the future, you may need to install expansion cards. The following sub-sections describe the slots and the expansion cards that they support.

Make sure to unplug the power cord before adding or removing expansion cards. Failure to do so may cause you physical injury and damage motherboard components.

2.5.1 Installing an expansion card

To install an expansion card:

1. Before installing the expansion card, read the documentation that came with it and make the necessary hardware settings for the card.

2. Remove the system unit cover (if your motherboard is already installed in a chassis).

3. Remove the bracket opposite the slot that you intend to use. Keep the screw for later use.

4. Align the card connector with the slot and press rmly until the card is

completely seated on the slot.

5. Secure the card to the chassis with the screw you removed earlier.

6. Replace the system cover.

2.5.2 Conguring an expansion card

After installing the expansion card, congure it by adjusting the software settings.

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, conicts 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.

The fan connectors support cooling fans of 350 mA~1000 mA (24 W max.) or a total of 1 A~3.48 A (41.76 W max.) at +12V. Connect the fan cables to the fan connectors on the motherboard, making sure that the black wire of each cable matches the ground pin of the connector.

DO NOT forget to connect the fan cables to the fan connectors. Insufcient air ow inside the system may damage the motherboard components. These are

not jumpers! DO NOT place jumper caps on the fan connectors!

• Only the CPU_FAN, CHA_FAN1~3, and OPT_FAN1~3 connectors support the ASUS Q-Fan 2 feature.

• If you install two VGA cards, we recommend that you plug the chassis fan cable to the motherboard connector labled CHA_FAN1 or CHA_FAN3 for better themal environment.

This connector is for a chassis-mounted intrusion detection sensor or switch. Connect one end of the chassis intrusion sensor or switch cable to this connector. The chassis intrusion sensor or switch sends a high-level signal to this connector when a chassis component is removed or replaced. The signal is then generated as a chassis intrusion event.

By default, the pin labeled “Chassis Signal” and “Ground” are shorted with a jumper cap. Remove the jumper caps only when you intend to use the chassis intrusion detection feature.

9. ATX power connectors (24-pin EATXPWR, 8-pin EATX12V)

These connectors are for ATX power supply plugs. The power supply plugs

are designed to t these connectors in only one orientation. Find the proper orientation and push down rmly until the connectors completely t.

• Make sure to remove the cap on the EATX12V connector before connecting an 8-pin EPS +12V power plug.

• Use only an 8-pin EPS +12V power plug for the EATX12V connector.

For a fully congured system, we recommend that you use a power supply

unit (PSU) that complies with ATX 12 V Specication 2.0 (or later version)

and provides a minimum power of 400 W.

• Do not forget to connect the 4-pin/8pin EATX12V power plug; otherwise,

the system will not boot.

• Use of a PSU with a higher power output is recommended when

conguring a system with more power-consuming devices. The system

may become unstable or may not boot up if the power is inadequate.

• If you are uncertain about the minimum power supply requirement for your

system, refer to the Recommended Power Supply Wattage Calculator at http://support.asus.com/PowerSupplyCalculator/PSCalculator. aspx?SLanguage=en-us for details.

• The ATX 12 V Specication 2.0-compliant (400W) PSU has been tested

to support the motherboard power requirements with the following conguration:

CPU: Intel® Pentium® Extreme 3.73GHz Memory: 512 MB DDR2 (x4) Graphics card: ASUS EAX1900XT Parallel ATA device: IDE hard disk drive Serial ATA device: SATA hard disk drive (x2) Optical drive: DVD-RW

• If you want to use two high-end PCI Express x16 cards, use a PSU with 500W to 600W power or above to ensure the system stability.

10. Digital audio connector (4-1 pin SPDIF_OUT for ASUS HDMI VGA card)

This connector is for an additional Sony/Philips Digital Interface (S/PDIF) port(s). If you are using an ASUS HDMI-equipped graphics card, connect the HDMI card to this connector with a S/PDIF Out cable.

The ASUS HDMI-equipped graphics card and the S/PDIF Out cable are purchased separately.
