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.

PRIME X470-PRO CPU socket AM4

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.

1.1.4System 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.

Memory configurations

You may install 2 GB, 4 GB, 8 GB, and 16 GB unbuffered 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.

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

This jumper allows you to clear the CMOS RTC RAM data of the system setup

information such as date, time, and system passwords. Chapter1

PRIME X470-PRO Clear RTC RAM

To erase the RTC RAM:

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.

If the steps above do not help, remove the onboard battery and short the two pins again to clear the CMOS RTC RAM data. After clearing the CMOS, reinstall the battery.

•These connectors are set to [AHCI] by default. If you intend to create a Serial ATA RAID set using these connectors, set the SATA Mode Selection item in the BIOS to

[RAID].

•Before creating a RAID set, refer to section RAID configurations or the manual bundled in the motherboard support DVD.

•When using NCQ, set the SATA Mode in the BIOS to [AHCI]. Refer to section SATA

Configuration for details.
