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

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

• Use a grounded wrist strap or touch a safely grounded object or 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 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.

2.3Central Processing Unit (CPU)

The motherboard comes with a surface mount Socket P0 (LGA 3647) designed for the Intel® Xeon® processor product family.

•Upon purchase of the motherboard, ensure 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

Socket P0 (LGA 3647).

•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.

2.3.1Installing the CPU and heatsink

To install a CPU:

1.Locate the CPU socket on the motherboard.

Before installing the CPU, ensure that the socket box is facing toward you and the triangle mark is on the top-right position.

2. Remove the PNP cap from the CPU socket.

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 at both ends then insert the DIMM into the socket. Apply force to both ends of the DIMM simultaneously until the retaining clip

clicks into place and the DIMM is seated securely in place.

Locked Retaining Clip

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

•To install two or more DIMMs, refer to the user guide bundled with the motherboard

package.

•Refer to the user guide for qualified vendor lists of the memory modules.

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 table Standard Interrupt assignments in section Interrupt assignments for more information.

3.Install the software drivers for the expansion card.
