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

1.1Before 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.

1.3Central Processing Unit (CPU)

This motherboard comes with a surface mount LGA 3647 socket designed for the Intel® Xeon W-3200 Processor Family 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.

The CPU fits 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.

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.

The motherboard comes with twelve (12) Dual Inline Memory Modules (DIMM) slots designed for DDR4 (Double Data Rate 4) memory modules.

A DDR4 memory 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 16 GB and 32 GB RDIMMs; 32 GB, and 64 GB LRDIMMs; and 64GB, and 128GB LRDIMM 3DS 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.

•The DIMMs are purchased separately.

•Visit the ASUS website for the latest QVL.

1.7Onboard jumpers

		1. Clear RTC RAM jumper
	1Chapter	The Clear RTC RAM jumper allows you to clear the Real Time Clock (RTC) RAM
		in the CMOS, which contains the date, time, system passwords, and system setup
		parameters.

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 re-enter data.

DO NOT short-circuit the pins except when clearing the RTC RAM. Short-circuiting or placing a jumper cap will cause system boot failure!

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

Ensure the ATX power supply is switched off or the power cord is detached from the power supply when enabling or disabling the VGA controller settings using this jumper.

•If a VGA Card is installed into a PCI Express x16 Slot, the onboard VGA function will still be enabled.

•BMC Remote Management Function will still be available when VGA controller settings is set to disabled, but the display will be disabled on the client device.
