2-10	Chapter 2: Hardware Information

2.4.3Installing a DIMM on a single clip DIMM socket

Ensure to unplug the power supply before adding or removing DIMMs or other system components. Failure to do so may cause severe damage to both the motherboard and the components.

1.	Unlock a DIMM socket by pressing the DIMM notch
	retaining clip outward.
2.	Align a DIMM on the socket such that
	the notch on the DIMM matches the
	DIMM slot key on the socket.
	DIMM slot key	Unlocked retaining clip
	A DIMM is keyed with a notch so that it fits in only one direction. DO NOT force a DIMM into
	a socket in the wrong direction to avoid damaging the DIMM.
3.	Hold the DIMM by both of its ends
	then insert the DIMM vertically into the
	socket. Apply force to both ends of the
	DIMM simultaneously until the retaining
	clip snaps back into place and the
	DIMM cannot be pushed in any further
	to ensure proper sitting of the DIMM.
		Locked Retaining Clip

Always insert the DIMM into the socket vertically to prevent DIMM notch damage.

Removing a DIMM from a single clip DIMM socket

1.Press the retaining clip outward to unlock the DIMM.

2. Remove the DIMM from the socket.

Support the DIMM lightly with your fingers when pressing the retaining clips. The DIMM might get damaged when it flips out with extra force.

2.5Expansion slots

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

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

2.5.1Installing 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 firmly 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.

2.5.2Configuring an expansion card

After installing the expansion card, configure 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.

2.6Jumpers

1.Clear RTC RAM (3-pin CLRTC1)

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.Move the jumper cap from the default pins 1–2 to pins 2–3. Keep the cap on pins 2–3 for about 5 to 10 seconds, then move the cap back to pins 1–2.

3.Plug the power cord and turn ON the computer.

4.Hold down the <Del> key during the boot process and enter BIOS setup to reenter data.

DO NOT remove the cap on CLRTC jumper default position except when clearing the RTC

RAM. Removing the cap will cause system boot failure!

If the steps above do not help, remove the onboard battery and move the jumper again to clear the CMOS RTC RAM data. After the CMOS clearance, reinstall the battery.
