Notes:

1. Resolution support is subject to memory bandwidth availability
2. Single 8K at 60 Hz display, supported by monitors that accept dual DP input for tiled screen

3.1.2 Intel® Graphics for 14

^th Gen Intel Processors

Intel® Graphics for 14 ^th Gen Intel Processors features the following:

• DirectX* 12.1 support
• OpenGL* 4.6 support
  • Max HDMI resolution 4096x2304 at 60Hz
  • Max DP resolution 7680x4320 at 60Hz ⁺
• OpenCL* 3.0 support

3.1.3 Display Emulation

Display emulation is supported using the HDMI ports so that the system may be remotely accessed in a headless configuration or be capable of tolerating display connectivity interruptions without the operating system redetecting and rearranging the overall display layout. The display emulation feature may be enabled in BIOS Setup with the following checkboxes:

- "Virtual display emulation": provides a 1280x1024 virtual display when no displays are connected to the system and provides an additional 1280x1024 virtual display if one display is attached to the system. If two displays are attached to the HDMI ports these displays will be enabled and no virtual displays will be provided.

- "Persistent display emulation": emulates that both displays are always connected to the system no matter their actual connection status. The EDID information from each display will remain programmed through S3, S4, S5 and G3 power states until the feature is disabled.

- When "Persistent display emulation" is enabled another drop-down menu ("Inconsistent Display Device") will become visible that allows the user to select the behavior of the system when the display device EDID is inconsistent with the EDID stored by the system.

• "Block boot" (default selection): the BIOS will display a warning message with options and will wait indefinitely for a user selection.
• "Countdown": the BIOS will display a warning message with options and will wait 10 seconds before booting.

NOTE

When using "Persistent display emulation" it would be expected behavior for the system not to properly drive displays different than those connected when the feature was enabled, as the EDID parameters of the initially connected displays are still being driven by the system. In order to retrain the system for different displays, the persistent display emulation feature must be disabled in the BIOS, the system rebooted, and then the persistent display emulation feature must be reenabled.

3.2 SATA Interface

The board provides the following SATA interfaces:

• One SATA 6.0 Gb/s combined Data and Power connector
- Accepts up to 7mm in height 2.5" drives

The PCH provides independent SATA ports with a theoretical maximum transfer rate of 6 Gb/s. A point-to-point interface is used for host to device connections.

3.3 Real-Time Clock Subsystem

A coin-cell battery (CR2032) powers the real-time clock and CMOS memory. When the computer is not plugged into a wall socket, the battery has an estimated life of three years. When the computer is plugged in, the standby current from the power supply extends the life of the battery. The clock is accurate to ±13 minutes/year at 25°C with 3.3 VSB applied via the power supply 5 V STBY rail.

NOTE

If the battery and AC power fail, date and time values will be reset and the user will be notified during the POST.

When the voltage drops below a certain level, the BIOS Setup program settings stored in CMOS RAM (for example, the date and time) might not be accurate. Replace the battery with an equivalent one. Figure 2 on page 21 shows the location of the battery.

System can power on from G3/AC power loss state without the Real-Time Clock battery.

3.4 LAN Subsystem

3.4.1 RJ-45 LAN Connector with Integrated LEDs

Two LEDs are built into the RJ-45 LAN connector (shown in Figure 7).

Figure 7. LAN Connector LED Locations

Table 5 describes the LED states when the board is powered up and the LAN subsystem is operating.

Table 5. LAN Connector LED States

LED	LED Color	LED State	Condition
Link	Green	Off	LAN link is not established
		Solid	LAN link is established
		Blinking	LAN activity is occurring
Data Rate	Green/Yellow	Off	10/100 Mb/s data rate is selected
		Yellow	1000 Mb/s data rate is selected
		Green	2500 Mb/s data rate is selected

3.5 Hardware Management Subsystem

3.5.1 Fan Monitoring

Fan monitoring can be implemented using third-party software.

3.5.2 System States and Power States

Table 6 describes the ACPI states supported by the processor.

Table 6. Systems States

State	Description
GO/S0/C0	Full On:CPU operating. Individual devices may be shut to save power. The different CPU operating levels are defined by Cx states.
GO/S0/Cx	Cx State:CPU manages C-states by itself and can be in lower power states.
G1	Suspend-To-RAM (STR):The system context is maintained in system DRAM, but power is shut to non-critical circuits. Memory is retained and refreshes continue. All external clocks are shut off; RTC clock and international oscillator clocks are still toggling.
G1/S4	Suspend-To-Disk (STD):The context of the system is maintained on the disk. All power is then shut to the system except to the logic required to resume. Externally appears the same as S5 but may have different wake events.
G2/S5	Soft Off:System context not maintained. All power is shut except for the logic required to restart. A full boot is required when waking.
G3	Mechanical Off:System context not maintained. All power shut except for the RTC. No "Wake" events are possible because the system does not have any power. This state occurs if the user removes the batteries, turns off a mechanical switch, or if the system power supply is at a level that is insufficient to power the "waking" logic.

3.5.2.1 Wake-up Devices and Events

Table 7 lists the devices or specific events that can wake the computer from specific states.

Table 7. Wake-up Devices and Events

Devices/events that wake up the system...	...from this sleep state	Comments
Power switch	S0iX, S4, S5 1
RTC alarm	S0iX, S4, S5 1	Option for monitor to remain in sleep state
LAN	S0iX, S5 1,3,4	“S5 WOL after G3” is supported; monitor to remain in sleep state
WIFI	S0iX
Bluetooth	S0iX
USB	S0iX, S4, S5 1,2,3	Wake S4, S5 controlled by BIOS option (not after G3)
PCIe	S0iX, S4 1	Via WAKE; monitor to remain in sleep state
HDMI CEC	S0iX, S4, S5 1	Wake S4, S5 controlled by BIOS option

Notes:

1. S4 implies operating system support only.
2. Will not wake from Deep S4/S5. USB S4/S5 Power is controlled by BIOS. USB S5 wake is controlled by BIOS. USB S4 wake is controlled by OS driver, not just BIOS option.
3. Windows Fast startup will block wake from LAN and USB from S5.
4. WoL from S4 via Magic Packet is not supported.

NOTE

The use of these wake-up events from an ACPI state requires an operating system that provides full ACPI support. In addition, software, drivers, and peripherals must fully support ACPI wake events.

4 Technical Reference

4.1 Connectors and Headers

CAUTION

Only the following connectors and headers have overcurrent protection: back panel USB Type A and Type C, front panel USB, internal USB headers, internal power header, and DC Vin jack.

All other connectors and headers are not overcurrent protected and should connect only to devices inside the computer's chassis, such as fans and internal peripherals. Do not use these connectors or headers to power devices external to the computer's chassis. A fault in the load presented by the external devices could cause damage to the computer, the power cable, and the external devices themselves.

Furthermore, improper connection of USB header single wire connectors may eventually overload the overcurrent protection and cause damage to the board.

Figure 8. Connection Diagram for Front Panel Header (2.0 mm Pitch)

4.1.1.1.1 Hard Drive Activity LED Header

Pins 1 and 3 can be connected to an LED to provide a visual indicator that data is being read from or written to a hard drive. Proper LED function requires a SATA hard drive or optical drive connected to an onboard SATA connector.

Pins 5 and 7 can be connected to a momentary single pole, single throw (SPST) type switch that is normally open. When the switch is closed, the board resets and runs the POST.

4.1.1.1.3 Power/Sleep LED Header

Pins 2 and 4 can be connected to a one- or two-color LED. Table 13 and Table 14 show the possible LED states.

Table 13. States for a One-Color Power LED

LED State	Description
Off	Power off
Blinking	Standby
Steady	Normal operation

Table 14. States for a Dual-Color Power LED

LED State	Description
Off	Power off
Blinking (white)	Standby
Steady (white)	Normal operation

NOTE

The LED behavior shown in Table 13 is default – other patterns may be set via BIOS setup.

4.1.1.1.4 Power Switch Header

Pins 6 and 8 can be connected to a front panel momentary-contact power switch. The switch must pull the SW_ON# pin to ground for at least 50 ms to signal the power supply to switch on or off (the time requirement is due to internal debounce circuitry on the board). At least two seconds must pass before the power supply will recognize another on/off signal.

4.1.1.2 BIOS Security Jumper

CAUTION

Do not move a jumper with the power on. Always turn off the power and unplug the power cord from the computer before changing a jumper setting. Otherwise, the board could be damaged.

Figure 9 shows the location of the BIOS Security Jumper. The 3-pin jumper determines the BIOS Security program's mode.

Figure 9. Location of the BIOS Security Jumper

Table 15 describes the jumper settings for the three modes: normal, lockdown, and configuration.

Table 15. BIOS Security Jumper Settings

Function/Mode	Jumper Setting	Configuration
Normal	1-2	The BIOS uses current configuration information and passwords for booting.
Lockdown	2-3	The BIOS uses current configuration information and passwords for booting, except:All POST Hotkeys are suppressed (prompts are not displayed and keys are not accepted. For example, F2 for Setup, F10 for the Boot Menu).Power Button Menu is not available (see Section 5.3.2 Power Button Menu).BIOS updates are not available except for automatic Recovery due to flash corruption.
Configuration	None	BIOS Recovery Update process if a matching *.bio file is found. Recovery Update can be cancelled by pressing the Esc key.If the Recovery Update was cancelled or a matching *.bio file was not found, a Config Menu will be displayed. The Config Menu consists of the following (followed by the Power Button Menu selections):[1] Suppress this menu until the BIOS Security Jumper is replaced.[2] Clear BIOS User and Supervisor Passwords.[3] Reset Intel® AMT to default factory settings.[4] Clear Trusted Platform Module.WARNING! Data encrypted with the TPM will no longer be accessible if the TPM is cleared.[F2] Intel® Visual BIOS.[F4] BIOS Recovery.See Section 5.3.2 Power Button Menu

4.1.1.3 Intel® Management Engine BIOS Extension (Intel® MEBX) Reset Header

The Intel® MEBX reset header (see Figure 1) allows you to reset the CMOS values to the factory defaults in situations when the system may have become unresponsive, such as after a failed BIOS update. It achieves this by placing a low on the reset pin of the Real Time Clock (RTC).

Momentarily shorting pins 1 and 2 with a jumper will accomplish reset CMOS values to default.

CAUTION Always turn off the power and unplug the power cord from the computer before installing an MEBX reset jumper. The jumper must be removed before reapplying power. The system must be allowed to reach end of POST before reset is complete. Otherwise, the board could be damaged.

NOTE After using the MEBX Reset, a "CMOS battery failure" warning will occur during the next POST. This is expected and does not indicate a component failure.

CAUTION Care must be taken to avoid inadvertent shorting of the bottom cover screw to the header during bottom cover reassembly. Assemble the bottom cover before reapplying power to the system.

4.1.1.4 Fan Header Current Capability

Table 16 lists the current capability of the fan headers.

Table 16. Fan Header Current Capability

Fan Header	Maximum Available Current
Processor fan	1A

4.1.1.5 Power Supply Connectors

NOTE External power voltage, 12-20 (±5%) V DC, is dependent on the type of power by used. System power requirements will depend on actual system configurations chosen in the integrator, as well as end user expansion preferences. It is the system integrator's responsibility to ensure an appropriate power budget for the system configuration is properly used based on the system-level components chosen.

CAUTION

There is no isolation circuitry between the external DC jack and the internal 2 x 2 power connector. It is the system integrator's responsibility to ensure no more than one power supply unit is or can be attached to the board at any time and to ensure the external DC jack is covered if the internal 2 x 2 power connector is to be used. Simultaneous connection of both external and internal power supply units could result in potential damage to the board, power supplies, or other hardware.

The board has the following power supply connectors:

• External Power Supply – the board can be powered through a 12-20 V DC connector on the back panel. The back-panel DC connector is compatible with a 5.5 mm/OD (outer diameter) and 2.5 mm/ID (inner diameter) plug, where the inner contact is +12-20 V DC and the shell is GND. The maximum current rating is 10 A.
• Internal Power Supply – the board can alternatively be powered via the internal 12-20 V DC 2 x 2 power connector, where pins 1 and 2 are +12-20 V DC and pins 3 and 4 are GND. The maximum current rating is 10 A (5A per pins 1 and 2).
  The connector used is Molex Micro-Fit (3mm pitch), right-angled, 4-pos/dual row (2x2).

4.2.3 Form Factor

The board is designed to fit into a custom chassis. Figure 17 illustrates the mechanical form factor for the board. Dimensions are given in millimeters. The outer dimensions are 107.50 millimeters (front to back from furthest excursion of rear HDMI to front Type C) by 101.60 millimeters (side to side). The mounting post centers are identified by the 95.00, 94.75, and 90.50 millimeters measurements.

Figure 18 shows the height dimensions of the board. Dimensions are in mm. The tallest feature on the user accessible side of the board when in use is the M.2 retention pegs, and on the CPU side is the thermal module.

Figure 18. Board Height Dimensions

4.3 Thermal Considerations

CAUTION

Failure to ensure appropriate airflow may result in reduced performance of both the processor and/or voltage regulator or, in some instances, damage to the board.

All responsibility for determining the adequacy of any thermal or system design remains solely with the system integrator. Intel makes no warranties or representations that merely following the instructions presented in this document will result in a system with adequate thermal performance.

CAUTION

Ensure that the ambient temperature does not exceed the board's maximum operating temperature. Failure to do so could cause components to exceed their maximum case temperature and malfunction. For information about the maximum operating temperature, see the environmental specifications in Section O.

CAUTION

Ensure that proper airflow is maintained in the processor voltage regulator circuit. Failure to do so may result in shorter than expected product lifetime.

4.4 Reliability

The demonstrated Mean Time Between Failures (MTBF) is done through 24/7 testing. Full ASUS NUC systems in chassis with memory, SSD or HDD, and a fan are ran at 100% on time for 90 days continuously while running system wide stress inducing software in a 40 °C ambient air temperature chamber. The demonstrated MTBF for ASUS NUC Board NUC14RV is >50,000 hours.

4.5 Environmental

Table 18 lists the environmental specifications for the board.

CAUTION

If the external ambient temperature exceeds 40° C, further thermal testing is required to ensure components do not exceed their maximum operating temperature.

Note: The operating temperature of the board may be determined by measuring the air temperature from the junction of the heatsink fins and fan, next to the attachment screw, in a closed chassis, while the system is in operation.
Note: Before attempting to operate this board, the overall temperature of the board must be above the minimum operating temperature specified. It is recommended that the board temperature be at least room temperature before attempting to power on the board. The operating and non-operating environment must avoid condensing humidity.

The board uses an ASUS AMI BIOS core that is stored in the Serial Peripheral Interface Flash Memory (SPI Flash) and can be updated through multiple methods (see Section 5.2). The SPI Flash contains the BIOS Setup program, POST, the PCI auto-configuration utility, LAN EEPROM information, and Plug and Play support. The SPI Flash includes a flash memory device of either 32MB or 64MB depending on SKU.

The BIOS Setup program can be used to view and change the identification information and the BIOS settings for the system. The BIOS Setup program is accessed by pressing after the POST memory test beings and before the operating system boots.

5.2 BIOS Updates

The BIOS can be updated using one of the following methods:

1. Express BIOS (Windows-based) Update
2. F7 Update
3. Power Button Menu Update
4. UEFI Shell Update

5.2.1 BIOS Recovery

It is unlikely that anything will interrupt a BIOS update; however, if an interruption occurs the BIOS could be unstable. Table 19 lists the drives and media types that can be used for BIOS recovery. The BIOS recovery media does not need to be made bootable.

Table 19. Acceptable Drives/Media Type for BIOS Recovery

Media Type (Note)	Can be used for BIOS recovery?
Hard disk drive (connected to SATA or USB)	Yes
USB flash drive	Yes
NVME SSD (M.2 interface)	Yes

NOTE Supported file systems for BIOS recovery: NTFS (sparse, compressed, or encrypted

files are not supported), FAT32, EXT

5.3 Boot Options

In the BIOS Setup program, the user can choose to boot from a hard drive, removable driver, or the network. The default setting is for the hard drive to be the first boot device, the removable drive second, and the network third.

NOTE The network can be selected as a boot device. This selection allows booting from the onboard LAN or a network add-in card with a remote boot ROM installed. Pressing the key during POST automatically forces booting from the LAN. To use this key during POST, the User Access Level in the BIOS Setup program's Security menu must be set to Full.

5.3.1 Boot Device Selection During Post

Pressing the key during POST causes a boot device menu to be displayed. The menu displays the list of available boot devices.

5.3.2 Power Button Menu

As an alternative to Configuration Mode or normal POST hotkeys, the user can use the power button to access a menu with BIOS and boot options. The Power Button Menu is accessible via the following sequence:

1. System is in S4/S5 (not G3).
2. User pushes the power button and holds it down for 3 seconds.
3. The Power Button LED will be white color for the first 3 seconds. After 3 seconds, switch Power Button LED to yellow color to signal the user to release the power button.
4. User releases the power button before the 4-second shutdown override.
   If this boot path is taken, the BIOS will use default settings, ignoring settings in VPD where possible. At the point where Setup Entry/Boot would be in the normal boot path, the BIOS will display the following prompt and wait for a keystroke:

If an unrecognized key is hit, then the BIOS will do nothing and wait for another keystroke. If one of the listed hotkeys is hit, the BIOS will follow the indicated boot path. Password requirements must still be honored.

Table 20. Power Button Menu Options

Keystroke	Option	Description
[ESC]	Normal Boot
[F2]	BIOS Setup Menu
[F3]	Disable Fast Boot	Note: Will only be displayed if at least one Fast Boot optimization is enabled.If Disable Fast Boot is selected, the BIOS will disable all Fast Boot optimizations and reset the system.
[F4]	BIOS Recovery	The BIOS will search for a matching .CAP file from the \EFI\Intel folder in the supported media with the supported file system. If a matching recovery capsule is found, the BIOS will display the following:BIOS will Recover toin 20 seconds.[ESC] Cancel RecoveryRecovery will proceed if not cancelled via the ESC key within 20 seconds.The BIOS shall display the recovery progress. If a BIOS .CAP file was notdetected (or the BIOS Recovery was cancelled) then the BIOS will reset the system and continue normally to POST.
[F5]	Restore BIOS Settings	The BIOS will restore the current setup settings and the current defaults to the build time defaults in the case of a boot issue caused by setup variable changes.
[F7]	Update BIOS	BIOS Update during the BDS phrase. The BIOS will update independent of any OS loading and provides a menu UI accessible during boot up. This is not a recovery tool and will not overwrite a corrupt BIOS or ME firmware.
[F9]	Remote Assistance	Note: Will only be displayed if Remote Assistance is supported.
[F10]	Enter Boot Menu
[F12]	Network Boot

5.4 Hard Disk Drive Password Security Feature

The Hard Disk Drive Password Security feature blocks ready and write access to the hard disk drive until the correct password is given. Hard disk drive passwords are set in BIOS Setup and are prompted for BIOS POST. For convenient support for resuming from S3, the system BIOS will automatically unlock drives on resume from S3. Valid password characters are A-Z, a-z, and 0-9. Passwords may be up to 32 characters in length.

The User hard disk drive password, when set, will be required on each power cycle until the Master Key or User hard disk drive password is submitted.

The Master Key hard disk drive password, when set, will not lock the drive. The Master Key hard disk drive password exists as an unlock override if the User hard disk drive password is forgotten. Only the User hard disk drive password, when set, will cause a hard disk to be locked on a system power cycle. Table 21 show the effects of setting the hard disk drive passwords.

Table 21. Master Key and User Hard Disk Drive Password Functions

Password Set	Password During Boot
Neither	None
Master only	None
User only	User only
Master and User Set	User

During every POST, if a User hard disk drive password is set, POST execution will pause with the following prompt to force the User to enter the Master Key or the User hard disk drive password:

"Enter Hard Disk Drive Password:"

Upon successful entry of the Master Key or User hard disk drive password, the system will continue with normal POST.

If the hard disk drive password is not correctly entered, the system will go back to the above prompt. The User will have three attempts to correctly enter the hard disk drive password. After the third unsuccessful attempt, the system will halt with the following message:

"Hard Disk Drive Password Entry Error"

A manual power cycle will be required to resume system operation.

NOTE As implemented on the ASUS NUC14RV board, the hard disk drive password security are only supported on the SATA Port 0 (M.2) or the SATA port 1 (onboard SATA connector).

5.5 BIOS Security Features

The BIOS includes security features that restrict access to the BIOS Setup program and who can boot the computer. A Supervisor and User password can be set for the BIOS Setup program and for botting the computer, with the following restrictions:

• The Supervisor password gives unrestricted access to view and change all the Setup options in the BIOS Setup program. This is Supervisor Mode.
• The User password gives restricted access to view and change Setup options in the BIOS Setup program. This is User Mode.
• If only the Supervisor password is set, pressing the key at the password prompt of the BIOS Setup program allows the user restricted access to Setup.
• If both the Supervisor and User passwords are set, users can enter either the Supervisor or User password to access Setup. Users have access to Setup regardless to which password is used.
• Setting the User password restricts who can boot the computer. The password prompt will be displayed before the computer boots. If only the Supervisor password is set, the computer boots without asking for a password. If both passwords are set, the user can enter either password to boot the computer.
• For enhanced security, use different passwords for the Supervisor and User passwords.
• Valid password characters are A-Z, a-z, 0-9, and special characters. Passwords may be up to 20 characters in length.
• To clear a set password, enter a blank password after entering the existing password.

Table 22 shows the effects of setting the Supervisor password and User password. This table is for reference only and is not displayed on the screen.
