1.3 Processor

A soldered-down 7th generation Intel® Core™ i3-7100U dual-core processor with up to a

maximum 15 W TDP (if thermal margin is available).

 Intel® HD Graphics 620

 Integrated memory controller

 Integrated PCH

NOTE

There are specific requirements for providing power to the processor. Refer to Section 2.5.1 on

page 56 for information on power supply requirements.

Product Description

1.4 System Memory

The board has two 260-pin SO-DIMM sockets and supports the following memory features:

 1.2 V DDR4 SDRAM SO-DIMMs with gold plated contacts

 Two independent memory channels with interleaved mode support

 Unbuffered, single-sided or double-sided SO-DIMMs

 32 GB maximum total system memory (with 8 Gb memory technology). Refer to Section 2.1.1

on page 39 for information on the total amount of addressable memory.

 Minimum recommended total system memory: 2048 MB

 Non-ECC SO-DIMMs

 Serial Presence Detect

 DDR4 1866/2133 MHz SDRAM SO-DIMMs

NOTE

To be fully compliant with all applicable DDR SDRAM memory specifications, the board should be

populated with SO-DIMMs that support the Serial Presence Detect (SPD) data structure. This

allows the BIOS to read the SPD data and program the chipset to accurately configure memory

settings for optimum performance. If non-SPD memory is installed, the BIOS will attempt to

correctly configure the memory settings, but performance and reliability may be impacted or the

SO-DIMMs may not function under the determined frequency.

NOTE

Intel NUC Board NUC7i3BNB supports only 4 Gb and 8 Gb memory technologies (also referred to

as “SDRAM density”). Table 4 lists the supported SO-DIMM configurations. Table 5 lists the SO-

DIMM configurations that are not supported.

provides full ACPI support. ACPI features include:

 Plug and Play (including bus and device enumeration)

 Power management control of individual devices, add-in boards (some add-in boards may

require an ACPI-aware driver), video displays, and hard disk drives

 Methods for achieving less than 15-watt system operation in the power-on/standby

sleeping state

 A Soft-off feature that enables the operating system to power-off the computer

 Support for multiple wake-up events (see Table 12 on page 35)

 Support for a front panel power and sleep mode switch

Table 10 lists the system states based on how long the power switch is pressed, depending on

how ACPI is configured with an ACPI-aware operating system.

1.12.1.1 System States and Power States

Under ACPI, the operating system directs all system and device power state transitions. The

operating system puts devices in and out of low-power states based on user preferences and

knowledge of how devices are being used by applications. Devices that are not being used can be

turned off. The operating system uses information from applications and user settings to put the

system as a whole into a low-power state.

Table 11 lists the power states supported by the board along with the associated system power

targets. See the ACPI specification for a complete description of the various system and power

states.

1.12.2.1 Power Input

When resuming from an AC power failure, the computer returns to the power state it was in

before power was interrupted (on or off). The computer’s response can be set using the Last

Power State feature in the BIOS Setup program’s Boot menu.

1.12.2.2 Instantly Available PC Technology

Instantly Available PC technology enables the board to enter the ACPI S3 (Suspend-to-RAM)

sleep-state. While in the S3 sleep-state, the computer will appear to be off (the power supply is

only supplying Standby power, and the front panel LED will be amber or secondary color if dual

colored, or off if single colored.) When signaled by a wake-up device or event, the system quickly

returns to its last known wake state. Table 12 on page 35 lists the devices and events that can

wake the computer from the S3 state.

The use of Instantly Available PC technology requires operating system support and drivers for

any installed M.2 add-in card.

1.12.2.3 LAN Wake Capabilities

LAN wake capabilities enable remote wake-up of the computer through a network. The LAN

subsystem monitors network traffic at the Media Independent Interface. Upon detecting a Magic

Packet* frame, the LAN subsystem asserts a wake-up signal that powers up the computer.

1.12.2.4 Wake from USB

USB bus activity wakes the computer from an ACPI S3 state (not after G3).

NOTE

Wake from USB requires the use of a USB peripheral that supports Wake from USB.

Product Description

1.12.2.5 WAKE# Signal Wake-up Support

When the WAKE# signal on the PCI Express bus is asserted, the computer wakes from an ACPI S3

or S4 state.

1.12.2.6 Wake from S5

When the RTC Date and Time is set in the BIOS, the computer will automatically wake from an

ACPI S5 state.

1.12.2.7 Wake from Consumer IR

CIR activity wakes the computer from an ACPI S3, S4, or S5 state.

1.12.2.8 +5 V Standby Power Indicator LED

2 Technical Reference

2.1 Memory Resources

2.1.1 Addressable Memory

The board utilizes 32 GB of addressable system memory. Typically the address space that is

allocated for PCI Conventional bus add-in cards, PCI Express configuration space, BIOS (SPI Flash

device), and chipset overhead resides above the top of DRAM (total system memory). On a

system that has 32 GB of system memory installed, it is not possible to use all of the installed

memory due to system address space being allocated for other system critical functions. These

functions include the following:

 BIOS/SPI Flash device (64 Mb)

 Local APIC (19 MB)

 Direct Media Interface (40 MB)

 PCI Express configuration space (256 MB)

 PCH base address registers PCI Express ports (up to 256 MB)

 Memory-mapped I/O that is dynamically allocated for M.2 add-in cards (256 MB)

 Integrated graphics shared memory (up to 512 MB; 64 MB by default)

The board provides the capability to reclaim the physical memory overlapped by the memory

mapped I/O logical address space. The board remaps physical memory from the top of usable

DRAM boundary to the 4 GB boundary to an equivalent sized logical address range located just

above the 4 GB boundary. All installed system memory can be used when there is no overlap of

system addresses.

2.2 Connectors and Headers

CAUTION

Only the following connectors and headers have overcurrent protection: back panel and front

panel USB.

The other internal 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.

This section describes the board’s connectors and headers. The connectors and headers can be

divided into these groups:

 Front panel I/O connectors

 Back panel I/O connectors

2.5 Electrical Considerations

2.5.1 Power Supply Considerations

System power requirements will depend on actual system configurations chosen by 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 assessed based

on the system-level components chosen.

2.6 Thermal Considerations

CAUTION

A chassis with a maximum internal ambient temperature of 50 oC at the processor fan inlet is

recommended. If the internal ambient temperature exceeds 50 oC, further thermal testing is

required to ensure components do not exceed their maximum case temperature.

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 2.8.

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.

Technical Reference

Table 29 provides maximum case temperatures for the components that are sensitive to thermal

changes. The operating temperature, current load, or operating frequency could affect case

temperatures. Maximum case temperatures are important when considering proper airflow to

cool the board.

Table 29. Thermal Considerations for Components

Component

Maximum Case Temperature

Processor

For processor case temperature, see processor datasheets and processor

specification updates

To ensure functionality and reliability, the component is specified for proper operation when

Case Temperature is maintained at or below the maximum temperature listed in Table 30. This is

a requirement for sustained power dissipation equal to Thermal Design Power (TDP is specified

as the maximum sustainable power to be dissipated by the components). When the component is

dissipating less than TDP, the case temperature should be below the Maximum Case

Temperature. The surface temperature at the geometric center of the component corresponds to

Case Temperature.

It is important to note that the temperature measurement in the system BIOS is a value reported

by embedded thermal sensors in the components and does not directly correspond to the

Maximum Case Temperature. The upper operating limit when monitoring this thermal sensor is

Tcontrol.

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.

3 Overview of BIOS Features

3.1 Introduction

The board uses Intel Visual BIOS that is stored in the Serial Peripheral Interface Flash Memory

(SPI Flash) and can be updated using a disk-based program. The SPI Flash contains the Visual

BIOS Setup program, POST, the PCI auto-configuration utility, LAN EEPROM information, and

Plug and Play support.

The BIOS displays a message during POST identifying the type of BIOS and a revision code. The

initial production BIOSs are identified as BNKBL357.86A.

The Visual BIOS Setup program can be used to view and change the BIOS settings for the

computer. The BIOS Setup program is accessed by pressing the <F2> key after the Power-On

Self-Test (POST) memory test begins and before the operating system boot begins.

NOTE

The maintenance menu is displayed only when the board is in configure mode. Section 2.3 on

page 53 shows how to put the board in configure mode.

3.2 BIOS Flash Memory Organization

The Serial Peripheral Interface Flash Memory (SPI Flash) includes a 64 Mb flash memory device.

3.3 System Management BIOS (SMBIOS)

SMBIOS is a Desktop Management Interface (DMI) compliant method for managing computers in

a managed network.

The main component of SMBIOS is the Management Information Format (MIF) database, which

contains information about the computing system and its components. Using SMBIOS, a system

administrator can obtain the system types, capabilities, operational status, and installation dates

for system components. The MIF database defines the data and provides the method for

accessing this information. The BIOS enables applications such as third-party management

software to use SMBIOS. The BIOS stores and reports the following SMBIOS information:

 BIOS data, such as the BIOS revision level

 Fixed-system data, such as peripherals, serial numbers, and asset tags

 Resource data, such as memory size, cache size, and processor speed

 Dynamic data, such as event detection and error logging

Non-Plug and Play operating systems require an additional interface for obtaining the SMBIOS

information. The BIOS supports an SMBIOS table interface for such operating systems. Using

this support, an SMBIOS service-level application running on a non-Plug and Play operating

system can obtain the SMBIOS information. Additional board information can be found in the

BIOS under the Additional Information header under the Main BIOS page.

3.4 Legacy USB Support

Legacy USB support enables USB devices to be used even when the operating system’s USB

drivers are not yet available. Legacy USB support is used to access the BIOS Setup program, and

to install an operating system that supports USB. By default, Legacy USB support is set to

Enabled.

Legacy USB support operates as follows:

1. When you apply power to the computer, legacy support is disabled.

2. POST begins.

3. Legacy USB support is enabled by the BIOS allowing you to use a USB keyboard to enter and

configure the BIOS Setup program and the maintenance menu.

4. POST completes.

5. The operating system loads. While the operating system is loading, USB keyboards and mice

are recognized and may be used to configure the operating system. (Keyboards and mice are

not recognized during this period if Legacy USB support was set to Disabled in the BIOS

Setup program.)

6. After the operating system loads the USB drivers, all legacy and non-legacy USB devices are

recognized by the operating system, and Legacy USB support from the BIOS is no longer

used.

Overview of BIOS Features

To install an operating system that supports USB, verify that Legacy USB support in the BIOS

Setup program is set to Enabled and follow the operating system’s installation instructions.

3.5 BIOS Updates

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

 Intel Express BIOS Update Utility, which enables automated updating while in the Windows

environment. Using this utility, the BIOS can be updated from a file on a hard disk, a USB

drive (a flash drive or a USB hard drive), or a CD-ROM, or from the file location on the Web.

 Intel Flash Memory Update Utility, which requires booting from DOS. Using this utility, the

BIOS can be updated from a file on a hard disk, a USB drive (a flash drive or a USB hard drive),

or a CD-ROM.

 Intel® F7 switch during POST allows a user to select where the BIOS .bio file is located and

perform the update from that location/device. Similar to performing a BIOS Recovery without

removing the BIOS configuration jumper.

 Intel® Visual BIOS has an option to update the BIOS from a valid .bio file located on a hard

disk or USB drive. Enter Intel Visual BIOS by pressing <F2> during POST.

 Using Front Panel menu option

Both utilities verify that the updated BIOS matches the target system to prevent accidentally

installing an incompatible BIOS.

NOTE

Review the instructions distributed with the upgrade utility before attempting a BIOS update.

kits/000005636.html

3.5.1 Language Support

The BIOS Setup program and help messages are supported in US English. Check the Intel web

site for support.

3.6 BIOS Recovery

It is unlikely that anything will interrupt a BIOS update; however, if an interruption occurs, the

BIOS could be damaged. Table 32 lists the drives and media types that can and cannot be used

for BIOS recovery. The BIOS recovery media does not need to be made bootable.

Overview of BIOS Features

3.7 Boot Options

In the BIOS Setup program, the user can choose to boot from a hard drive, optical drive,

removable drive, or the network. The default setting is for the optical drive to be the first boot

device, the hard drive second, removable drive third, and the network fourth.

NOTE

Optical drives are not supported by the onboard SATA connectors. Optical drives are supported

only via the USB interfaces.

3.7.1 Network Boot

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 <F12> 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.

3.7.2 Booting Without Attached Devices

For use in embedded applications, the BIOS has been designed so that after passing the POST,

the operating system loader is invoked even if the following devices are not present:

 Video adapter

 Keyboard

 Mouse

3.7.3 Changing the Default Boot Device During POST

Pressing the <F10> key during POST causes a boot device menu to be displayed. This menu

displays the list of available boot devices. Table 33 lists the boot device menu options.

Table 33. Boot Device Menu Options

Boot Device Menu Function Keys

Description

<> or <>

Selects a default boot device

<Enter>

Exits the menu, and boots from the selected device

<Esc>

Exits the menu and boots according to the boot priority defined

through BIOS setup

3.7.4 Power Button Menu

As an alternative to Back-to-BIOS Mode or normal POST Hotkeys, the user can use the power

button to access a menu. 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 system will emit three short beeps from the front panel (FP) audio port, then stop to

signal the user to release the power button. The FP power button LED will also change from

Blue to Amber when the user can 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:

[ESC] Normal Boot

[F2] Intel Visual BIOS

[F3] Disable Fast Boot

[F4] BIOS Recovery

[F7] Update BIOS

[F10] Enter Boot Menu

[F12] Network Boot

[F2] Enter Setup is displayed instead if Visual BIOS is not supported.

[F3] Disable Fast Boot is only displayed if at least one Fast Boot optimization is enabled.

[F9] Remote Assistance is only displayed if Remote Assistance is supported.

If an unrecognized key is hit, then the BIOS will beep 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.

If Disable Fast Boot is selected, the BIOS will disable all Fast Boot optimizations and reset the

system.

Overview of BIOS Features

3.8 Hard Disk Drive Password Security Feature

The Hard Disk Drive Password Security feature blocks read and write accesses to the hard disk

drive until the correct password is given. Hard Disk Drive Passwords are set in BIOS SETUP and

are prompted for during BIOS POST. For convenient support of S3 resume, 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 19 characters in length.

The User hard disk drive password, when installed, will be required upon each power-cycle until

the Master Key or User hard disk drive password is submitted.

The Master Key hard disk drive password, when installed, will not lock the drive. The Master Key

hard disk drive password exists as an unlock override in the event that the User hard disk drive

password is forgotten. Only the installation of the User hard disk drive password will cause a hard

disk to be locked upon a system power-cycle.

Table 34 shows the effects of setting the Hard Disk Drive Passwords.

Table 34. Master Key and User Hard Drive Password Functions

Password Set

Password During Boot

Neither

None

Master only

None

User only

Master and User Set

Master or 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 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 hard disk drive password attempt, the system will halt with the message:

Hard Disk Drive Password Entry Error

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

NOTE

As implemented on Intel NUC Board NUC7i3BNB Hard Disk Drive Password Security is only

supported on either SATA port 0 (M.2 ) or SATA Port 1 (onboard SATA connector). The passwords

are stored on the hard disk drive so if the drive is relocated to another computer that does not

support Hard Disk Drive Password Security feature, the drive will not be accessible.

Currently, there is no industry standard for implementing Hard Disk Drive Password Security on

AHCI or NVME drives. Hard drive encryption can still be implemented and does not require Hard

Disk Drive Password Security.

3.9 BIOS Security Features

The BIOS includes security features that restrict access to the BIOS Setup program and who can

boot the computer. A supervisor password and a user password can be set for the BIOS Setup

program and for booting 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 the supervisor mode.

 The user password gives restricted access to view and change Setup options in the BIOS

Setup program. This is the user mode.

 If only the supervisor password is set, pressing the <Enter> 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

password or the user password to access Setup. Users have access to Setup respective to

which password is entered.

 Setting the user password restricts who can boot the computer. The password prompt will be

displayed before the computer is booted. 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, and 0-9. Passwords may be up to 20 characters in

length.

 To clear a set password, enter a blank password after entering the existing password.

Table 35 shows the effects of setting the supervisor password and user password. This table is
