Product Description
This Apacer memory module, part number 78.B1GS9.4040B, is a 4GB DDR4 Registered DIMM (RDIMM) operating at a speed of 2666MHz. RDIMMs are designed for server and high-end workstation environments, where they help improve system stability and allow for larger memory capacities by reducing the electrical load on the memory controller. The 'registered' nature means that the data signals are buffered by a register chip on the module itself. The 1Rx8 configuration signifies that the module is single-ranked, with each memory chip on the module having an organization of x8 bits. This configuration is common and generally offers good performance for most server workloads. The DDR4 technology represents a significant advancement over previous DDR generations, offering higher speeds, lower voltage requirements, and increased bandwidth. With a capacity of 4GB and a speed of 2666MHz, this Apacer RDIMM is suitable for upgrading or populating memory in compatible server motherboards that support DDR4 RDIMMs. It is a standard component for enhancing the memory resources of systems used for virtualization, database management, scientific computing, and other memory-intensive applications.
