This is a high capacity 8GB DDR5 RAM memory module produced by Samsung , specifically designed for use on high-end servers and workstations. It is part of the DDR5 memory generation, which offers significantly higher data transfer speed and increased energy efficiency than the previous DDR4 generation. The acronym PC5-5600B indicates its maximum speed. Being a non-ECC (Non-Error Correcting Code) and Unbuffered module, it is intended for use in consumer systems (laptop and AIO) rather than on servers. The 1Rx16 organization indicates that it is a Rank Single Module with DRAM components at $\times 16$, which makes it very common in basic configurations of many modern laptops.
