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)

The motherboard comes with an AM4 socket designed for AMD Ryzen™ 2nd Generation / Ryzen™ 1st Generation / Ryzen™ with Radeon™ Vega Graphics / 7th Generation A-Series/ Athlon X4 Processors.

1 Chapter

The AM4 socket has a different pinout design. Ensure that you use a CPU designed for the AM4 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.

1-4	Chapter 1: Product Introduction

1.1.4System memory

The motherboard comes with four (4) 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

ROG STRIX X470-I 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.

• AMD Ryzen™ processors support ECC and non-ECC un-buffered memory.

•AMD 7th Gen A-series / Athlon™ processors support non-ECC un-buffered memory.

•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.

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.

1.1.6Jumper

	1.	Clear RTC RAM (2-pin CLRTC)
		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.	Use a metal object such as a screwdriver to short the two pins.
		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.

Except when clearing the RTC RAM, never place a metal object on the CLRTC jumper.

Placing a metal object will cause system boot failure!

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

the system is ON, in sleep mode, or in soft-off mode. This is a reminder that you should

shut down the system and unplug the power cable before removing or plugging in any

Chapter

motherboard component. The illustration below shows the location of the onboard LED

2.Q LEDs (CPU, DRAM, VGA, BOOT)

Q LEDs check key components (CPU, DRAM, VGA card, and booting devices) in 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 order which the LEDs light up may vary per CPU.

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.
