Take note of the following precautions before you install motherboard components or change any motherboard settings.

• Make sure that your power supply unit (PSU) can provide at least

the minimum power required by your system. See “8. ATX power

connectors” on page 2-26 for details.

• Unplug the power cord from the wall socket before touching any component.

• Use a grounded wrist strap or touch a safely grounded object or to a metal object, such as the power supply case, before handling components to avoid damaging them due to static electricity

• Hold components by the edges to avoid touching the ICs on them.

• Whenever you uninstall any component, place it on a grounded antistatic pad or in the bag that came with the component.

• Before you install or remove any component, ensure that the ATX

power supply is switched off or the power cord is detached from the power supply. Failure to do so may cause severe damage to the motherboard, peripherals, and/or components.

Onboard LED

The motherboard comes with a standby power LED that lights up to indicate that the system is ON, in sleep mode, or in soft-off mode. This is a reminder that you should shut down the system and unplug the power cable before removing or plugging in any motherboard component.

M2N4-SLI CPU Socket AM2

The motherboard comes with a 940-pin AM2 socket designed for the AMD

Athlon™ 64 X2/AMD Athlon™ 64 FX/AMD Athlon™ 64 and AMD Sempron™

processors.

Make sure you use a CPU is designed for the AM2 socket. The CPU ts in

only one correct orientation. DO NOT force the CPU into the socket to prevent bending the connectors on the socket and damaging the CPU!

2.3.1 Installing the CPU

To install a CPU:

1. Locate the CPU socket on the motherboard.

2. Unlock the socket by pressing the lever sideways, then lift it up to a 90º angle.

2-6 Chapter 2: Hardware information

2.3.2 Installing the heatsink and fan

The the AMD Athlon™ FX, AMD Athlon 64™, AMD Sempron™ or AMD Athlon™ X2 processor require a specially designed heatsink and fan

assembly to ensure optimum thermal condition and performance.

Make sure that you use only qualied heatsink and fan assembly.

Follow these steps to install the CPU heatsink and fan.

1. Place the heatsink on top of the installed CPU, making sure that the

heatsink ts properly on the retention module base.

• The retention module base is already installed on the motherboard upon purchase.

• You do not have to remove the retention module base when installing the CPU or installing other motherboard components.

• If you purchased a separate CPU heatsink and fan assembly, make

sure that a Thermal Interface Material is properly applied to the CPU heatsink or CPU before you install the heatsink and fan assembly.

2. Attach one end of the retention bracket to the retention module base.

3. Align the other end of the retention bracket (near the retention bracket lock) to the retention module base. A clicking sound denotes that the retention bracket is in place.

Make sure that the fan and heatsink assembly perfectly

ts the retention mechanism

com) for the latest Qualied Vendors List.

Important notice on installing Windows

If you install Windows

XP 32-bit version Operating System (OS), the

XP 32-bit version

limitation of this OS version is that it may reserve a certain amount of memory space for system devices. We recommend that you install less than 3 GB system memory if you would like to work under Windows 32-bit version OS. The excess memory installation will not cause any

usage problem, but it will not give users the benet of manipulating this

excess memory space.

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.

Support the DIMM lightly with

your ngers when pressing

the retaining clips. The DIMM might get damaged when it

ips out with extra force.

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 the 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.

1. 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!

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.
