Product Description
The HP T9V78AV is a comprehensive 128GB memory upgrade kit, consisting of four 32GB DDR4 Registered DIMM (RDIMM) modules. This kit is specifically engineered for high-end servers and workstations that demand substantial memory capacity and robust performance. Operating at a speed of 2400MHz, these modules provide excellent bandwidth for handling large datasets, complex simulations, virtualization, and other memory-intensive enterprise workloads. The DDR4 standard offers significant improvements in speed, power efficiency, and density over previous DDR generations. Each module in the kit is a 32GB RDIMM, featuring a 2 Rank x 4 bits (2Rx4) configuration. The dual-rank design can enhance performance by allowing the memory controller to interleave operations across the two ranks, potentially increasing data throughput. The RDIMM architecture includes an on-board register to buffer command and address signals, reducing the load on the memory controller and enabling greater system stability and scalability, which is crucial for enterprise-grade hardware. With a CAS Latency of CL17, these modules are optimized for their 2400MHz speed, providing a balance between latency and bandwidth. They operate at the low voltage of 1.2V, contributing to reduced power consumption and heat generation within the system. The inclusion of Registered ECC (Error-Correcting Code) is a critical feature for server environments, as it ensures data integrity by detecting and correcting memory errors, thereby minimizing downtime and preventing data corruption. The T9V78AV kit represents a significant performance and capacity boost for compatible HP and other enterprise systems.
