| Processor | |
| Processor manufacturer The manufacturer that produced the processor. | AMD |
| Processor socket Mechanical component(s) that provides mechanical and electrical connections between a microprocessor and a printed circuit board (PCB). This allows the processor to be replaced without soldering. | Socket AM4 |
| Compatible processor series A processor which is compatible with this device, belongs to a 'series' which is part of 'family' e.g Celeron D, Celeron G, Celeron M, or, in some cases, is the same as 'family'. | AMD Ryzen |

| Memory | |
| Supported memory types Types of memory which can be used with the product. | DDR4-SDRAM |
| Number of memory slots | 2 |
| Memory slots type A memory slot, also known as a memory socket or RAM slot, is what allows computer memory (RAM) to be inserted into the computer. Depending on the motherboard, there will usually be 2 to 4 memory slots (sometimes more on high-end motherboards). The most common types of RAM are SDRAM and DDR for desktop computers and SODIMM for laptop computers, each having various types and speeds. | DIMM |
| Memory channels | Dual-channel |
| ECC ECC means Error Correction Code, and it is memory that is able to detect and correct some memory errors without user intervention. |
 |
| Non-ECC |
|
| Supported memory clock speeds Memory clock speed is the time it takes for a computer to complete basic operations. It refers to the computer's processing speed and is measured in hertz. It is however not such a reliable measure of a computer's speed as it doesn't take into account other factors like RAM and cache size. | 2133,2400,2667,2933,3200,3466,3600,3733,3800,3866,4000,4133,4200,4266,4333,4400,4466,4533,4600,4666 MHz |

| Internal I/O | |
| USB 2.0 connectors The end of a cable with a USB 2.0 connector. USB 2.0 was released in April 2000 (now called "Hi-Speed"), adding higher maximum signaling rate of 480 Mbit/s (effective throughput up to 35 MB/s or 280 Mbit/s), in addition to the "USB 1.x Full Speed" signaling rate of 12 Mbit/s. USB 2.0 connectors are usually colored black. | 4 |
| USB 3.2 Gen 1 (3.1 Gen 1) connectors This is a connector (normally attached to a cable) for USB 3.0. USB 3.0 is the second major revision of the Universal Serial Bus (USB) standard for computer connectivity. First introduced in 2008, USB 3.0 adds a new transfer mode called "SuperSpeed," (distinguishable from USB 2.0 by either the blue colour of the port or the initials SS) capable of transferring data at up to 5Gbit/s—more than ten times as fast as the 480 Mbit/s top speed of USB 2.0. | 2 |
| Number of SATA III connectors Serial ATA (Advanced Technology Attachment) (SATA) is a computer bus interface that connects host bus adapters to mass storage devices such as hard disk drives and optical drives. SATA III (revision 3.x) interface, formally known as SATA 6Gb/s, is a third generation SATA interface running at 6.0Gb/s. The bandwidth throughput, which is supported by the interface, is up to 600MB/s. This interface is backwards compatible with SATA 3 Gb/s interface. | 4 |

| Ethernet LAN (RJ-45) ports Number of Ethernet LAN (RJ-45) ports (connecting interfaces) in the device. Ethernet LAN (RJ-45) ports allow a computer to connect to the ethernet. | 1 |
| PS/2 ports quantity The number of PS/2 connectors for keyboards and mice. Its name comes from the IBM Personal System/2. | 1 |
| VGA (D-Sub) ports quantity Number of VGA (D-Sub) ports (connecting interfaces) in the device. The VGA (D-Sub) connector is a 15 pin connector between a computer and a monitor. It was first introduced in 1987 by IBM. | 1 |
| HDMI ports quantity The number of sockets (ports) for HDMI connections. HDMI (High-Definition Multimedia Interface) is a compact audio/video interface for transferring uncompressed video data and compressed/uncompressed digital audio data from a HDMI-compliant device ("the source device") to a compatible computer monitor, video projector, digital television, or digital audio device. HDMI is a digital replacement for existing analog video standards. | 1 |
| DVI-D ports quantity This is the amount of DVI-I interfaces. Digital Visual Interface (DVI) is a video display interface developed by the Digital Display Working Group (DDWG). The digital interface is used to connect a video source to a display device, such as a computer monitor. DVI-D means DVI digital, which means it can only support digital, but not analog. | 1 |

| BIOS type The BIOS (Basic Input/Output System) initializes and tests system hardware components, and loads a bootloader or an operating system from a mass memory device. The BIOS additionally provides abstraction layer for the hardware, i.e. a consistent way for application programs and operating systems to interact with the keyboard, display, and other input/output devices. There are several types of BIOS, including the motherboard ROM BIOS, video BIOS, drive controller BIOS, network adapter BIOS, and SCSI adapter BIOS. | UEFI AMI |
