ASRock B450M Pro4 AMD Socket AM4 Micro ATX VGA/DVI-D/HDMI DDR4 USB C 3.1 Motherboard

A concise list of wireless capabilities and features that the product supports, such as DDNS, EZ‑Router, Wake‑on‑LAN (WOL) and Wake‑on‑WAN (WOW). The value is a free‑text string that may include multiple comma‑separated items.

The type of connector used to supply 12‑volt electrical power to a device, such as a standard ATX power plug or other proprietary 12‑V connectors. It indicates the physical interface that allows the device to receive its main power supply.

The firmware interface used by a computer system to initialize hardware and load the operating system, such as UEFI or legacy BIOS. It indicates whether the motherboard supports modern features like secure boot, fast startup, or compatibility with older operating systems.

The vertical dimension of a cooling unit measured from its lowest to highest point. The value is expressed in a physical unit such as millimetres, centimetres or inches and applies to any cooler component where height is relevant, including air coolers, liquid radiators and passive heat sinks.

A web address that provides information about the processor compatibility for a motherboard or other computer component. The link typically directs users to a manufacturer’s support page where they can find which CPUs are supported, including details on socket type, chipset, and BIOS requirements.

The maximum count of display units that a product can accommodate or operate simultaneously, such as monitors, TVs, or other visual output devices. This value indicates how many separate displays the system is designed to support in its current configuration.

The brand or family of the graphics adapter present in a device, such as Intel, AMD, NVIDIA, Apple, or other vendors. It indicates the general source of the GPU technology and helps users compare visual performance across products.

A list of the video output connectors and protocols that a device can provide for transmitting visual signals, such as HDMI, DisplayPort, VGA, or USB‑C based outputs. Each entry indicates a distinct connector type or version (e.g., "HDMI 2.1", "DP 1.4"). This attribute helps users identify which displays or external devices the product can support.

The highest network transfer rate that a device’s wired Ethernet port can negotiate, expressed in common speed abbreviations such as "10/100", "10/100/1000" or "2.5GbE". This value indicates the maximum throughput achievable over the LAN connection.

The specific model or designation of the LAN (network) controller integrated into a device, such as "Intel I219-V" or "Realtek RTL8111H." This value identifies the exact network interface hardware used for Ethernet connectivity, enabling users to compare performance, compatibility, and support across products.

The form factor of the memory module that a product can accept, such as DIMM or SO‑DIMM. It indicates whether the device uses standard desktop RAM modules (DIMM) or smaller laptop‑style modules (SO‑DIMM).

The maximum operating frequency of a memory module, expressed in hertz (Hz). It indicates how many cycles per second the RAM can perform and is typically reported as MHz or GHz. This value helps users compare performance potential across different memory types and system configurations.

A list of the multi‑GPU configurations that a graphics card or motherboard can support, such as NVIDIA SLI, AMD CrossFireX, or NVLink. Each entry describes a distinct configuration and may include the number of GPUs involved (e.g., "2-way NVIDIA SLI", "3-way AMD CrossFireX").

The count of expansion slots on a device that support the PCI Express interface with a configuration of 16 lanes (x16) and are compliant with the Generation 3.x specification. This value indicates how many high‑bandwidth devices, such as graphics cards or other x16 peripherals, can be installed simultaneously.

A comma‑separated list that specifies the RAID configurations a storage device or controller can support, such as 0, 1, 5, 10 and special modes like JBOD. Each entry represents an independent configuration option available to the user.

The SMBIOS (System Management BIOS) version indicates the firmware revision that provides system information to the operating system and management tools. It is typically expressed as a numeric or alphanumeric string such as "2.7" or "3.1", and it helps users verify compatibility, update requirements, and support for hardware features.
