1.3 Installing the CPU

This motherboard uses an AMD Socket AM4 for AMD Ryzen™ 5000/4000 G/3000 Series Desktop Processors.

⚠️ CAUTION: Unplug all power cables before installing the CPU.

The AM4 socket has a specific pinout. Use only CPUs designed for AM4. The CPU fits in only one orientation. Do not force the CPU into the socket to prevent bending connectors and damaging the CPU!

Installation Steps:

Lift the CPU socket retention lever.
Align the CPU's triangle mark with the socket's triangle mark and gently place the CPU into the socket.
Lower the CPU socket retention lever back into place.
Apply Thermal Interface Material (TIM) to the CPU heatsink and CPU if necessary before installing the heatsink and fan.

1.4 System Memory

This motherboard features four DDR4 Dual Inline Memory Module (DIMM) sockets. The sockets are arranged for dual-channel operation.

Memory Installation and Configuration:

Channel Mapping: Channel A uses DIMM_A1 & DIMM_A2; Channel B uses DIMM_B1 & DIMM_B2.
Memory sizes can be mixed, but the system maps the total size of the lower-sized channel for dual-channel configuration. Excess memory from the higher-sized channel operates in single-channel mode.
For optimal compatibility, install DIMMs with the same CAS latency, version, and date code (D/C) from the same vendor.
DDR4 modules have a different notch than DDR, DDR2, or DDR3. Do not install incompatible memory types.
Default memory frequency depends on Serial Presence Detect (SPD). Overclocked modules may run at lower frequencies by default.
For system stability, use adequate memory cooling.
Refer to www.asus.com for the Memory QVL (Qualified Vendors Lists) and CPU-dependent memory frequency support.

Recommended Memory Configurations:

Install DIMMs in pairs for dual-channel performance. For example, install in DIMM_A1 and DIMM_B1, or DIMM_A2 and DIMM_B2 for two modules. For four modules, populate all slots.

Installing a DIMM:

Open the retention clips on the DIMM slot.
Align the notch on the DIMM with the notch in the slot.
Press down firmly on both ends of the DIMM until the retention clips snap into place.

To remove a DIMM:

Push down the retention clips on both ends of the DIMM.
Gently pull the DIMM straight up and out of the slot.

Chapter 2: BIOS and RAID Support

2.1 Knowing BIOS

The ASUS UEFI BIOS offers a user-friendly interface with mouse support, providing flexible and convenient navigation. The term "BIOS" in this manual refers to "UEFI BIOS" unless specified otherwise.

BIOS (Basic Input and Output System) stores hardware settings (storage configuration, overclocking, power management, boot device configuration) needed for system startup. Default BIOS settings ensure optimal performance under normal circumstances. Change default settings only if:

An error message prompts you to run BIOS Setup.
A new system component requires updated BIOS settings.

Inappropriate BIOS settings can lead to instability or boot failure. It is strongly recommended to change BIOS settings only with the help of trained personnel.

BIOS settings and options may vary by release version. Refer to the latest BIOS version for current details.

For more information on BIOS configurations, visit https://www.asus.com/support or scan the provided QR code (if available).

2.2 BIOS Setup Program

Use the BIOS Setup to update the BIOS or configure its parameters. Onscreen help guides navigation.

Entering BIOS at Startup

Press the or key during Power-On Self Test (POST).

Entering BIOS Setup After POST

Press ++ simultaneously.
Press the system chassis reset button.
Turn the system off and back on (use if the above options fail).

After any of these, press the key to enter BIOS Setup.

Connect a USB mouse for mouse control in BIOS Setup.
If the system becomes unstable after changing settings, load default settings by selecting Load Optimized Defaults (Exit menu) or pressing .
If the system fails to boot after changes, clear CMOS and reset the motherboard to default values.
The BIOS setup program does not support Bluetooth devices.

BIOS Setup can be used in two modes: EZ Mode and Advanced Mode. Switch modes via Setup Mode in the Boot menu or by pressing the hotkey.

2.3 ASUS EZ Flash 3

ASUS EZ Flash 3 allows BIOS updates without an OS-based utility. Ensure BIOS default settings are loaded for system compatibility and stability (select Load Optimized Defaults or press ).

To update the BIOS:

ℹ️ NOTE: This function supports USB flash disks formatted with FAT 32/16 and a single partition only.
⚠️ CAUTION: Do NOT shut down or reset the system during BIOS updates to prevent boot failure!

Insert a USB flash disk containing the latest BIOS file into a USB port.
Enter BIOS Setup (Advanced Mode), go to the Tool menu, select ASUS EZ Flash 3 Utility, and press .
Use Left/Right arrow keys to select the Drive field.
Use Up/Down arrow keys to find the USB flash disk with the BIOS file, then press .
Use Left/Right arrow keys to select the Folder field.
Use Up/Down arrow keys to find the BIOS file, then press to start the update. Reboot the system when done.

2.4 ASUS CrashFree BIOS 3

ASUS CrashFree BIOS 3 is an auto-recovery tool to restore the BIOS file if it fails or gets corrupted during an update. You can restore a corrupted BIOS using a USB flash drive containing the BIOS file.

Recovering the BIOS:

Download the latest BIOS version from https://www.asus.com/support/.
Rename the BIOS file to ASUS.CAP or PA520M2.CAP and copy it to a USB flash drive.
Turn on the system.
Insert the USB flash drive with the BIOS file into a USB port.
The utility will automatically check for the BIOS file. Upon finding it, it will read the file and enter ASUS EZ Flash 3.
You will need to enter BIOS Setup to recover BIOS settings. For system compatibility and stability, press to load default BIOS values.

⚠️ CAUTION: Do NOT shut down or reset the system while updating the BIOS! Doing so can cause system boot failure!

2.5 RAID Configurations

The motherboard includes the RaidXpert2 Configuration Utility, supporting RAID 0, RAID 1, and RAID 10 configurations.

For detailed RAID configuration information, refer to the RAID Configuration Guide available at https://www.asus.com/support.

RAID Definitions:

RAID 0 (Data striping): Optimizes two identical hard drives for parallel read/write operations, doubling data transfer rates. Requires two new, identical hard disk drives.
RAID 1 (Data mirroring): Creates an identical copy of data on a second drive. If one drive fails, the system uses the surviving drive. Provides data protection and fault tolerance. Requires two new drives or one existing and one new drive (new drive must be same size or larger).
RAID 10: Combines data striping (RAID 0) and data mirroring (RAID 1) without parity. Offers benefits of both RAID 0 and RAID 1. Requires four new hard disk drives or one existing and three new drives.
