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.

1.1.3Central Processing Unit (CPU)

This motherboard supports the Intel® Socket 1151 for Intel® Core™ 9000 series, 8th Generation Core™ i7/ i5/ i3, Pentium® and Celeron® processors, with memory and PCI Express controllers integrated to support dual-channel (4 DIMM) DDR4 memory and 16 PCI Express 3.0/2.0 lanes.

Ensure that you install the correct CPU designed for LGA1151 socket only. DO NOT install a CPU designed for LGA1150, LGA1155, and LGA1156 sockets in the LGA1151 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 LGA1151 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.

1-4	Chapter 1: Product Introduction

1.1.4System memory

The motherboard comes with four Double Data Rate 4 (DDR4) 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.

Recommended memory configurations

Chapter 1

TUF Z390-PRO GAMING

1-5

1 Chapter

Memory configurations

You may install 2 GB, 4 GB, 8 GB and 16 GB unbuffered and non ECC DDR4 DIMMs into the DIMM sockets.

•You may install varying memory sizes in Channel A and Channel B. The system

maps the total size of the lower-sized channel for the dual-channel configuration. Any excess memory from the higher-sized channel is then mapped for single-channel operation.

•This motherboard does not support DIMMs made up of 512 Mb (64 MB) chips or less (Memory chip capacity counts in Megabit, 8 Megabit/Mb = 1 Megabyte/MB).

• 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 (4 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 switch

The onboard switch allows you to fine-tune performance when working on a bare or opencase system. This is ideal for overclockers and gamers who continually change settings to enhance system performance.

1.

MemOK! II switch (MemOK!_II)

1

Chapter

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

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 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.

1.1.7Jumpers

1. Clear RTC RAM jumper (2-pin CLRTC)

This jumper allows you to clear the Real Time Clock (RTC) RAM in CMOS. You can

1Chapter

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.Short-circuit pin 1-2 with a metal object or jumper cap for about 5-10 seconds.

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

4.Hold down the <Delete> key during the boot process and enter BIOS setup to re-enter data.

Except when clearing the RTC RAM, never place a metal object or jumper cap on the

CLRTC jumper. Placing a metal object or jumper cap will cause system boot failure!

•If the steps above do not help, remove the onboard battery and place a metal object or jumper cap again to clear the CMOS RTC RAM data. After the CMOS clearance, reinstall the battery.

•You do not need to clear the RTC when the system hangs due to overclocking. For system failure due to overclocking, use the C.P.R. (CPU Parameter Recall) feature. Shut down and reboot the system so the BIOS can automatically reset parameter settings to default values.

•Due to the chipset behavior, AC power off is required to enable C.P.R. function. You must turn off and turn on the power supply or unplug and plug the power cord before rebooting the system.

2.	CPU Over Voltage jumper (3-pin CPU_OV)
	The CPU Over Voltage jumper allows you to set a higher CPU voltage for a flexible
	overclocking system, depending on the type of the installed CPU. To gain more CPU
	voltage setting, insert the jumper to pins 2-3. To go back to its default CPU voltage	1
	setting, insert the jumper to pins 1-2.

1.1.8Onboard LEDs

	1.	Q LEDs (BOOT_LED, VGA_LED, DRAM_LED, CPU_LED)
		Q LEDs check key components (CPU, DRAM, VGA card, and booting devices) in
	1Chapter	sequence during motherboard booting process. If an error is found, the corresponding
		LED remains lit until the problem is solved. This user-friendly design provides an
		intuitive way to locate the root problem within seconds.

The Q LEDs provide the most probable cause of an error code as a starting point for troubleshooting. The actual cause may vary from case to case.

2.Memory LED (Mem_LED)

The Mem_LED will light up and remain lit while the MemOK! II function is in use. When the re-training is complete, the Mem_LED will turn off.
