HP P28217-B21 64GB DDR4-2933MHz RDIMM 2Rx4 CL21 Memory

Product Description

The HP P28217-B21 is a high-capacity 64GB DDR4 memory module designed for enterprise-grade servers and workstations. Operating at a speed of 2933MHz, it provides substantial bandwidth to handle memory-intensive applications, large databases, and complex virtual environments. DDR4 technology offers improved performance, energy efficiency, and density compared to previous generations of RAM. This module is a Registered DIMM (RDIMM), which includes an onboard register chip. This register buffers command and address signals, reducing the electrical load on the memory controller. This feature is crucial for enabling higher memory capacities and ensuring system stability, making RDIMMs a standard for server applications. The 2Rx4 rank configuration indicates that the module is dual-ranked, with each rank utilizing an x4 data organization. Dual-rank modules can enhance performance by allowing the memory controller to access different ranks independently. The CAS latency is CL21, representing the number of clock cycles required for the memory to access a specific data column. This, combined with the 2933MHz speed, offers a strong performance profile for enterprise workloads. The module operates at the standard DDR4 voltage of 1.2V. Critically, it features ECC (Error-Correcting Code) functionality, which is essential for server environments. ECC detects and corrects single-bit memory errors, thereby enhancing data integrity and system reliability, minimizing the risk of downtime and data corruption. The P28217-B21 is a vital component for optimizing the performance and stability of compatible HP servers.
