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.

•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 LGA2066 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 eight (8) DDR4 (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 2 GB, 4 GB, 8 GB and 16 GB unbuffered and non ECC DDR4 DIMMs into the DIMM sockets.

For Intel® Core™ X-Series Processors you may install varying memory sizes in Channel A, Channel B, Channel C, and Channel D. The system maps the total size of the lower-sized channel for the quad-channel configuration. Any excess memory from the higher-sized channel is then mapped for single-channel operation.

• The default memory operation frequency is dependent on its Serial Presence Detect (SPD), which is the standard way of accessing information from a memory module. Under the default state, some memory modules for overclocking may operate at a lower frequency than the vendor-marked value.

•For system stability, use a more efficient memory cooling system to support a full memory load (8 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.

1.1.6Onboard buttons and switches

Onboard buttons and switches allow you to fine-tune performance when working on a bare or open-case system. This is ideal for overclockers and gamers who continually change settings to enhance system performance.

1.

Power-on button (START)

1

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 (RESET)

Press the reset button to reboot the system.

3.	MemOK! II switch (MemOK!_II)
	Installing DIMMs that are not compatible with the motherboard may cause system
	boot failure. The switch is enabled by default, allowing memory re-training when the
	motherboard is unresponsive due to memory problems. The Mem_LED will light up
1 Chapter	while re-training, and turn off when the re-training is complete.

•Refer to section 1.1.8 Onboard LEDs for the exact location of the MEM LED.

•The DRAM LED also lights up when the DIMM is not properly installed. Turn off the system and reinstall the DIMM before using the MemOK! II function.

•The MemOK! II switch does not function under Windows® OS environment.

•During the tuning process, the system loads and tests pretest profiles. It takes about 30 seconds for the system to test one set of profiles. If the test fails, the system reboots and tests the next set of profiles. The system will reboot multiple times when training, once the system has completed the training process the Mem_LED will turn off, please refrain from doing anything before the Mem_LED turns off.

•Due to memory tuning requirement, the system automatically reboots when each profile is tested. If the installed DIMMs still fail to boot after the whole tuning process, and the Mem_LED is turned off, please refer to the Q-code LED and Q-code table for more details on the error.

•If you turn off the computer and replace DIMMs during the tuning process, the system continues memory tuning after turning on the computer. To stop memory tuning, turn off the computer and unplug the power cord for about 5–10 seconds, then set the MemOK! II switch to disabled.

•Ensure to replace the DIMMs with ones recommended in the Memory QVL (Qualified Vendors Lists) at www.asus.com.

•We recommend that you download and update to the latest BIOS version from www.asus.com after using the MemOK! II function.
