HP 9DX63AV 128GB Kit (4x32GB) DDR4-2933MHz RDIMM 2Rx4 CL21 Memory

Product Description

The HP 9DX63AV is a high-performance memory kit designed to significantly boost the capabilities of compatible HP servers. This kit provides a total of 128GB of memory, distributed across four individual 32GB DDR4 Registered DIMMs (RDIMMs). DDR4 technology represents a significant advancement over previous DDR generations, offering higher speeds, lower power consumption, and increased density. The 2933MHz operating frequency, corresponding to PC4-23466, ensures rapid data transfer rates, which is crucial for memory-intensive server workloads such as virtualization, large databases, and high-performance computing. Each module in the kit features a 2Rx4 organization, indicating a dual-rank configuration with memory chips organized as x4. This configuration can enhance performance in certain server memory controllers by allowing for more efficient interleaving and access patterns. The CAS Latency (CL) of 21 specifies the number of clock cycles required for data retrieval after a command is issued. While higher CL values can sometimes indicate slower timings, in conjunction with the high frequency and DDR4 technology, it contributes to the overall performance profile of the module. As Registered DIMMs (RDIMMs), these modules include an onboard register that buffers command and address signals. This reduces the electrical load on the memory controller, enabling servers to support larger amounts of memory and maintain signal integrity. Furthermore, the inclusion of Registered ECC (Error-Correcting Code) provides enhanced data reliability by detecting and correcting single-bit errors, which is a standard requirement for mission-critical server operations. This 128GB kit is an ideal upgrade for HP servers requiring substantial, high-speed, and reliable memory.
