Safety information

Electrical safety

•To prevent electrical shock hazard, disconnect the power cable from the electrical outlet before relocating the system.

•When adding or removing devices to or from the system, ensure that the power cables for the devices are unplugged before the signal cables are connected. If possible, disconnect all power cables from the existing system before you add a device.

•Before connecting or removing signal cables from the motherboard, ensure that all power cables are unplugged.

•Seek professional assistance before using an adapter or extension cord. These devices could interrupt the grounding circuit.

•Ensure that your power supply is set to the correct voltage in your area. If you are not sure about the voltage of the electrical outlet you are using, contact your local power company.

•If the power supply is broken, do not try to fix it by yourself. Contact a qualified service technician or your retailer.

Operation safety

•Before installing the motherboard and adding devices on it, carefully read all the manuals that came with the package.

•Before using the product, ensure all cables are correctly connected and the power cables are not damaged. If you detect any damage, contact your dealer immediately.

•To avoid short circuits, keep paper clips, screws, and staples away from connectors, slots, sockets and circuitry.

•Avoid dust, humidity, and temperature extremes. Do not place the product in any area where it may become wet.

•Place the product on a stable surface.

•If you encounter technical problems with the product, contact a qualified service technician or your retailer.

Product Introduction

1.1Motherboard overview

1.1.1Before you proceed

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

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

•Before handling components, use a grounded wrist strap or touch a safely grounded object or a metal object, such as the power supply case, 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, or components.

The motherboard comes with a surface mount LGA 3647 socket designed for the Intel® Xeon® Skylake-SP product family series processors.

1 Chapter

Ensure that you install the correct CPU designed for LGA3647 socket only. DO NOT install a CPU designed for other sockets on the LGA3647 socket.

•Ensure that all power cables are unplugged before installing the CPU.

•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 LGA3647 socket.

•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.

1.1.4System memory

The motherboard comes with twelve (12) DDR 4 (Double Data Rate 4) Dual Inline Memory Modules (DIMM) slots.

A DDR4 module is notched differently from a DDR, DDR2 or DDR3 module. DO NOT install a DDR, DDR2 or DDR3 memory module to the DDR4 slot.

Memory configurations

You may install 4 GB, 8 GB, 16 GB, and 32 GB RDIMMs; and 32 GB, and 64 GB LRDIMMs into the DIMM sockets.

• For system stability, use a more efficient memory cooling system to support a full memory load (12 DIMMs) or overclocking condition.

•Always install the DIMMS with the same CAS Latency. For an optimum compatibility, we recommend that you install memory modules of the same version or data code (D/C) from the same vendor. Check with the vendor to get the correct memory modules.

•Visit the ASUS website for the latest QVL.

Power-on button

Chapter

The motherboard comes with a power-on button that allows you to power up or wake

up the system. The button also lights up when the system is plugged to a power source

indicating that you should shut down the system and unplug the power cable before

removing or installing any motherboard component.

2.Reset button

Press the reset button to reboot the system.

1.1.7Jumpers

	1.	Clear RTC RAM (3-pin CLRTC1)
		This jumper allows you to clear the Real Time Clock (RTC) RAM in CMOS. You can
Chapter		clear the CMOS memory of date, time, and system setup parameters by erasing the
		To erase the RTC RAM:
		CMOS RTC RAM data. The onboard button cell battery powers the RAM data in
		CMOS, which include system setup information such as system passwords.
1		1.	Turn OFF the computer and unplug the power cord.
		2.	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.
		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.

Except when clearing the RTC RAM, never remove the cap on CLRTC jumper default position. 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.
