1.3 Choosing a Computer Chassis

Choose a chassis big enough to install this motherboard.

As some features for this motherboard are implemented by cabling connectors on the motherboard to indicators and switches or buttons on the chassis, make sure your chassis supports all the features required.

If there is a possibility of adopting some more hard drives, make sure your chassis has sufficient power and space for them.

Most chassis have alternatives for I/O shield located at the rear panel. Make sure the I/O shield of the chassis matches the I/O port configuration of this motherboard. You can find an I/O shield specifically designed for this motherboard in its package.

1.4 Installing Motherboard

Most computer chassis have a base with many mounting holes to allow the motherboard to be securely attached, and at the same time, prevent the system from short circuits. There are two ways to attach the motherboard to the chassis base: (1) with studs, or (2) with spacers. Basically, the best way to attach the board is with studs. Only if you are unable to do this should you attach the board with spacers. Line up the holes on the board with the mounting holes on the chassis. If the holes line up and there are screw holes, you can attach the board with studs. If the holes line up and there are only slots, you can only attach with spacers. Take the tip of the spacers and insert them into the slots. After doing this to all the slots, you can slide the board into position aligned with slots. After the board has been positioned, check to make sure everything is OK before putting the chassis back on.

Always power off the computer and unplug the AC power cord before adding or removing any peripheral or component. Failing to so may cause severe damage to your motherboard and/or peripherals. Plug in the AC power cord only after you have carefully checked everything. Locate all the screw holes on the motherboard and the chassis base.

Place all the studs or spacers needed on the chassis base and have them tightened.

Face the motherboard’s I/O ports toward the chassis’s rear panel.

Line up all the motherboard’s screw holes with those studs or spacers on the chassis.

Install the motherboard with screws and have them tightened.

To prevent shorting the PCB circuit, please REMOVE the metal studs or spacers if they are already fastened on the chassis base and are without mounting-holes on the motherboard to align with. 1-4 Face the chassis’s rear panel. To install this motherboard:

For a 2-pin jumper, plug the jumper cap on both pins will make it CLOSE (SHORT). Remove the jumper cap, or plug it on either pin (reserved for future use) will leave it at OPEN position. SHORT OPEN OPEN Pin 1~2 SHORT Pin 2~3 SHORT For 3-pin jumper, pin 1~2 or pin 2~3 can be shorted by plugging the jumper cap in.

1.5.1 CMOS Memory Clearing Header and Backup Battery

The time to clear the CMOS memory occurs when (a) the CMOS data becomes corrupted, (b) you forgot the supervisor or user password preset in the BIOS menu, (c) you are unable to boot-up the system because the CPU ratio/clock was incorrectly set in the BIOS menu, or (d) whenever there is modification on the CPU or memory modules. This header uses a jumper cap to clear the CMOS memory and have it reconfigured to the default values stored in BIOS.

Pins 1 and 2 shorted (Default): Normal operation.

Pins 2 and 3 shorted: Clear CMOS memory. To clear the CMOS memory and load in the default values:

Power off the system.

Set pin 2 and pin 3 shorted by the jumper cap. Wait for a few seconds. Set the jumper cap back to its default settings --- pin 1 and pin 2 shorted.

Power on the system.

For incorrect CPU ratio/clock settings in the BIOS, press <Del> key to enter the BIOS setup menu right after powering on system.

Set the CPU operating speed back to its default or an appropriate value.

Another easy way to clear the CMOS memory can be done by switching the “EZ-CCMOS1”, see the section of “Connecting Rear Panel I/O Devices” in this manual for detail. (For AN52S only)

Please do shut down the system power before clearing CMOS memory. AN52S/AN52 1-5 CMOS Backup Battery: An onboard battery saves the CMOS memory to keep the BIOS information stays on even after disconnected your system with power source. Nevertheless, this backup battery exhausts after some five years. Once the error message like “CMOS BATTERY HAS FAILED” or “CMOS checksum error” displays on monitor, this backup battery is no longer functional and has to be renewed. To renew the backup battery:

Power off the system and disconnect with AC power source.

Remove the exhausted battery.

Insert a new CR2032 or equivalent battery. Pay attention to its polarity. The “+” side is its positive polarity.

Connect AC power source and power on the system.

Danger of explosion may arise if the battery is incorrectly renewed.

Renew only with the same or equivalent type recommended by the battery manufacturer.

Dispose of used batteries according to the battery manufacturer’s instructions. 1-6 AN52S/AN52

1.7 Installing Hardware

※ DO NOT scratch the motherboard when installing hardware. An accidentally scratch of a tiny surface-mount component may seriously damage the motherboard.

1.7.1 CPU Socket AM2

※ DO NOT touch or bend the delicate pins on the CPU whenever you are holding it. The installation procedures vary with different types of CPU fan-and-heatsink assembly. The one shown here is served for DEMO only. For detailed information on how to install the one you bought, refer to its installation guidelines.

1. Pull out the socket lever away from the

socket and fully lift it up over 90-degree angle. Locate and align the triangle mark with both the CPU and the socket body. Vertically place the CPU with its pin-side down into the socket. Be careful to insert the CPU into the socket. The CPU only fits in one orientation with the socket. DO NOT force the CPU into the socket.

2. After placing the CPU into position, push

the socket lever down into its locked position to secure the CPU. The lever clicks when it’s locked into position.

3. The heatsink for CPU may have thermal

interface material attached to its bottom. If not, applying a few squeeze of thermal paste to the CPU die will help to increase the contact. 1-10 AN52S/AN52 Hardware Setup

4. Place the heatsink and fan assembly

onto the retention frame. Match the heatsink clip with the socket mounting-lug. Hook the spring clip to the mounting-lug.

5. On the other side, push the retention

clip straight down to lock into the plastic lug on the retention frame.

6. Connect the CPU cooling fan power

cable to the CPUFAN1 connector on this motherboard. ※ The “CPUFAN1” connector can be connected either with a 3-Pin or 4-Pin CPU cooling fan. For a 3-Pin connection, there will be no speed control available in the BIOS setup menu; the CPU fan will run at full speed. Also, please watch out for the orientation when inserting 3-Pin plug into this 4-Pin fan connector. ※ The motherboard in this illustration is served for DEMO only, may not be the same type or model as the one described in this user’s manual. ※ A higher fan speed will be helpful for better airflow and heat-dissipation. Nevertheless, stay alert to not touch any heatsink since a high temperature generated by the working system is still possible. AN52S/AN52 1-11

1.7.2 DDR2 Memory Slots

To reach the performance of Dual Channel DDR2, the following rules must be obeyed:

For a 4-DIMM dual-channel installation: Populate 2 DIMM modules of the same type and size on slots [DIMM1]+[DIMM2], and another 2 DIMM modules of the same type and size on slots [DIMM3]+[DIMM4].

[DIMM1] and [DIMM2] slots are made of the same color. [DIMM3] and [DIMM4] are made of another same color. Usually there is no hardware or BIOS setup requires after adding or removing memory modules, but you will have to clear the CMOS memory first if any memory module related problem occurs. To install system memory:

Power off the computer and unplug the AC power cord before installing or removing memory modules.

Locate the DIMM slot on the board.

Hold two edges of the DIMM module carefully, keep away from touching its connectors.

Align the notch key on the module with the rib on the slot.

Firmly press the module into the slots until the ejector tabs at both sides of the slot automatically snap into the mounting notch. Do not force the DIMM module in with extra force as the DIMM module only fits in one direction.

Static electricity can damage the electronic components of the computer or optional boards. Before starting these procedures, ensure that you are discharged of static electricity by touching a grounded metal object briefly. 1-12 AN52S/AN52 Hardware Setup

5.1 Troubleshooting (How to Get Technical Support?)

Q: Do I need to clear the CMOS before I use a new motherboard to assemble my new computer system? A: Yes, we highly recommend that you clear the CMOS before installing a new motherboard. Please move the CMOS jumper from its default 1-2 position to 2-3 for a few seconds, and then back. When you boot up your system for the first time, follow the instructions in the user's manual to load the optimized defaults. Q: If my system hangs when I update the BIOS or set the wrong CPU parameters, what should I do? A: Whenever you update the BIOS or if the system hangs due to wrong CPU parameters setting, always clear CMOS jumper before booting up again. Q: Why does the system fail to boot up again right after a mechanical power-off? A: Please keep a 30-second interval between each mechanical power On/Off. Q: Why does the system fail to boot up and nothing displays on the screen after I did some over-clocking or non-standard settings inside the BIOS? A: It should not cause hardware or permanent damage to motherboard when BIOS settings were changed from default to over-clocking or non-standard status. We suggest the following three troubleshooting methods to discharge CMOS data, recover the hardware default status, and then making the motherboard work again. There is no need to bother returning the motherboard to where you bought it from or go through an RMA process. Step 1. Switch off the power supply unit and then switch it on again after one minute. If there is no power-switch on the power supply unit, disconnect its power cord for one minute and then reconnect. Press and hold the <Insert> key on the keyboard, and press the power-on button to boot up system. If it works, release the <Insert> key and hit <Del> key to enter the BIOS setup page to apply the correct settings. If the situation remains the same, repeat the procedures in Step 1 three times, or try Step 2. Step 2. Switch off the power supply unit or disconnect the power cord. Open the chassis cover. Locate the CCMOS jumper near the button battery. Change the jumper position from default 1-2 to 2-3 for one minute to discharge the CMOS data, and then put it back to default 1-2 position. Close the chassis and switch on the power supply unit or plug in the power cord. Press the power-on button to boot up system. If it works, hit <Del> key to enter the BIOS setup page to do the correct settings. Step 3. The same procedure as Step 2, but while discharging the CMOS data, pull out the ATX power connectors from motherboard and remove the button battery during CMOS discharge. AN52S/AN52 5-1 Appendix If the situation remains the same, try Step 3. Q: How to get a quick response for my request on technical support? A: Please carry out a simple troubleshooting before sending “Technical Support Form”: System boot-up fails after the system had been assembled: Check the motherboard’s supporting specifications first to see if all the key components attached in your system can meet. To do so, you may:

Remove all the unnecessary add-on devices (except the CPU, VGA card, DRAM, and Power Supply), and then reboot.

If the trouble still exists, try another VGA card of different brand/model to see if the system will start.

If the trouble still exists, try another memory module of different brand/model.

If the trouble still exists, try another CPU and Power Supply. If the system runs successfully, shut it down and start re-installing the interface cards and devices that were previously installed in the system. Re-install and start the system one at a time until the system won’t start. Malfunction in the OS: If the system hangs after resuming from S3 or some testing program, if the CPU cannot be recognized properly, if the display resolution mixed, or if a certain program cannot be executed, etc, you may:

Upgrade the motherboard’s latest BIOS version.
