| 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 3 3rd Gen, 3rd Generation AMD Ryzen 5, 3rd Generation AMD Ryzen 7, 3rd Generation AMD Ryzen 9 |
| 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 |
| 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. | 1866,2133,2400,2667,2800,2933,3000,3066,3200,3466,3600,3733,3866,4000,4133,4266,4400,4600 MHz |

| Supported storage drive types The type of storage drives the device is compatible with. | HDD & SSD |
| Supported storage drive interfaces | M.2, Serial ATA III |
| RAID levels RAID is a storage technology that combines multiple disk drive components into a logical unit for the purposes of data redundancy and performance improvement. Data is distributed across the drives in one of several ways, referred to as RAID levels, depending on the specific level of redundancy and performance required. | 0,1,10 |
| Graphics | |
| Parallel processing technology support Parallel processing technology is the simultaneous use of more than one CPU or processor core to execute a program or multiple computational threads. Ideally, parallel processing makes programs run faster because there are more engines (CPUs or Cores) running it. In practice, it is often difficult to divide a program in such a way that separate CPUs or cores can execute different portions without interfering with each other. Most computers have just one CPU, but some models have several, and multi-core processor chips are becoming the norm. There are even computers with thousands of CPUs. | Not supported |
| 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. | 2 |
| 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. | 1 |
| 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. | 6 |
