| Memory | |
| Supported memory types Types of memory which can be used with the product. | DDR5-SDRAM |
| Number of memory slots | 4 |
| 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 сompatibility | 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. | 6000,6400,8200 MHz |

| 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 |
