Chapter 2 Installation
This is a 4X4 (4.09-in x 4.02-in x 1.4-in, 10.4 cm x 10.2 cm x 3.6 cm) form factor motherboard.
Before you install the motherboard, study the configuration of your chassis to ensure that the motherboard fits into it.
Make sure to unplug the power cord before installing or removing the motherboard. Failure to do so may cause physical injuries to you and damages to motherboard components.
2.1 Screw Holes
Place screws into the holes to secure the motherboard to the chassis.
Do not over-tighten the screws! Doing so may damage the motherboard.
2.2 Pre-installation Precautions
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.
- To avoid damaging the motherboard components due to static electricity, NEVER place your motherboard directly on the carpet or the like. Also remember to use a grounded wrist strap or touch a safety grounded object before you handle components.
- Hold components by the edges and do not touch the ICs.
- Whenever you uninstall any component, place it on a grounded antistatic pad or in the bag that comes with the component.
- Heatsink (The thermal solution of whole system needs to be designed additionally.)
Before you install or remove any component, ensure that the power 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, and/or components.
2.3 Installation of Memory Modules (SO-DIMM)
4X4-R2000M / 4X4-R2000V provides two 260-pin DDR4 (Double Data Rate 4) SO-DIMM slots, and supports Dual Channel ECC/non-ECC Memory Technology.
Step 1. Align a SO-DIMM on the slot such that the notch on the SO-DIMM matches the break on the slot.
Step 2. Firmly insert the SO-DIMM into the slot until the retaining clips at both ends fully snap back in place and the SO-DIMM is properly seated.
1. For dual channel configuration, you always need to install identical (the same brand, speed, size and chip-type) DDR4 DIMM pairs.
2. It is unable to activate Dual Channel Memory Technology with only one memory module installed.
1. The SO-DIMM only fits in one correct orientation. It will cause permanent damage to the motherboard and the SO-DIMM if you force the SO-DIMM into the slot at incorrect orientation.
2. Please do not intermix different voltage SO-DIMMs on this motherboard.
2.4 Expansion Slots
There are two M.2 sockets on this motherboard.
M.2 sockets:
1 x M.2 (Key E, 2230) with PCIe x1, USB 2.0 for Wireless
1 x M.2 (KEY M, 2242/2260/2280) with PCIe Gen3 x4 and SATA3 for SSD

Chapter 3 UEFI SETUP UTILITY
3.1 Introduction
ASRock Industrial UEFI (Unified Extensible Firmware Interface) is a BIOS utility which offers tweak-friendly options in an advanced viewing interface. The UEFI system works with a USB mouse and offers users a faster, sleeker experience.
This BIOS utility can perform the Power-On Self-Test (POST) during system startup, record hardware parameters of the system, load operating system, and so on. The battery on the motherboard supplies the power needed to the CMOS when the system power is turned off, and the values configured in the UEFI utility are kept in the CMOS.
Please note that inadequate BIOS settings may cause system instability, mulfunction or boot failure. We strongly recommend that you do not alter the UEFI default configurations or change the settings only with the assistance of a trained service person.
If the system becomes unstable or fails to boot after you change the setting, try to clear the CMOS values and reset the board to default values. See your motherboard manual for instructions.
3.1.1 Entering BIOS Setup
You may run the UEFI Setup Utility by pressing <F2> or <Delete> right after you power on the computer; otherwise, the Power-On-Self-Test (POST) will continue with its test routines. If you wish to enter the UEFI Setup Utility after POST, restart the system by pressing <Ctl> + <Alt> + <Delete>, or by pressing the reset button on the system chassis.
You may also restart by turning the system off and then back on.
This setup guide explains how to use the UEFI Setup Utility to configure all the supported system. The screenshots in this manual are for reference only. UEFI Settings and options may vary owing to different BIOS release versions or CPU installed. Please refer to the actual BIOS version of the motherboard you purchased for detailed screens, settings and options.
3.1.2 UEFI Menu Bar
The top of the screen has a menu bar with the following selections:
| Main | For setting system time/date information |
| Advanced | For advanced system configurations |
| H/W Monitor | Displays current hardware status |
| Security | For security settings |
| Boot | For configuring boot settings and boot priority |
| Exit | Exit the current screen or the UEFI Setup Utility |
Because the UEFI software is constantly being updated, the following UEFI setup screens and descriptions for reference purpose only, and may vary from the latest BIOS and do not exactly match what you see on your screen.
3.1.3 Navigation Keys
Use < 
> key or <
> key to choose among the selections on the menu bar, and use < 
> key or <
> key to move the cursor up or down to select items, then press <Enter> to get into the sub screen. You can also use the mouse to click your required item.
Please check the following table for the descriptions of each navigation key.
| Navigation Key(s) | Description |
| + / – | To change option for the selected items |
| <Tab> | Switch to next function |
| <PGUP> | Go to the previous page |
| <PGDN> | Go to the next page |
| <HOME> | Go to the top of the screen |
| <END> | Go to the bottom of the screen |
| <F1> | To display the General Help Screen |
| <F7> | Discard changes and exit the SETUP UTILITY |
| <F9> | Load optimal default values for all the settings |
| <F10> | Save changes and exit the SETUP UTILITY |
| <F12> | Print screen |
| <ESC> | Jump to the Exit Screen or exit the current screen |
3.2 Main Screen (Advanced Mode)
When you enter the UEFI SETUP UTILITY, the Main screen will appear and display the system overview.
Because the UEFI software is constantly being updated, the following UEFI setup screens and descriptions are for reference purpose only, and they may not exactly match what you see on your screen. Options may also vary depending on the features of your motherboard.
3.3 Advanced Screen
In this section , you may setthe configurations for the following it ems: CPU Configuration, Chipset Configuration, Storage Configuration, Super IO Configuration,ACPI Configuration, USB Configuration, Power Configuration and Trusted Computing. 
Setting wrong values in this section may cause the system to malfunction.
Instant Flash
Instant Flash is a UEFI flash utility embedded in Flash ROM. This convenient UEFI update tool allows you to update system UEFI without entering operating systems first like Windows®. Just launch this tool and save the new UEFI file to your USB flash drive, floppy disk or hard drive, and then you can update your UEFI in only a few clicks without preparing an additional floppy diskette or other complicated flash utility. Please be noted that the USB flash drive or hard drive must use FAT32/16/12 file system. If you execute Instant Flash utility, the utility will show the UEFI files and their respective information. Select the proper UEFI file to update your UEFI, and reboot your system after UEFI update process completes.
3.3.1 CPU Configuration
PSS Support
Enable/disable the generation of ACPI _PPC, _PSS, and _PCT objects.
Core Performance Boost
