Product Description
The HP Z5K42AV is a comprehensive 128GB memory kit, comprising four individual 32GB DDR4 Registered DIMM (RDIMM) modules. This kit is specifically engineered for high-performance computing environments, including HP's Z Workstations and ProLiant servers, where substantial memory capacity and bandwidth are paramount. Operating at a speed of 2666MHz (PC4-21300), these modules facilitate rapid data access and processing, essential for demanding tasks such as 3D rendering, complex simulations, large-scale data analysis, and extensive virtualization. Each 32GB module in the Z5K42AV kit features a 2Rx4 rank configuration. This dual-rank design, combined with x4 organization of DRAM chips, allows for increased memory bandwidth and improved performance by enabling the memory controller to access different ranks and banks concurrently. The RDIMM format includes an onboard register that buffers command and address signals, reducing the electrical load on the memory controller and enabling higher memory capacities and greater system stability, which is critical for mission-critical enterprise applications. With a CAS Latency (CL) of 19, the modules offer a balance between speed and timing accuracy. This kit is ideal for users pushing the limits of their systems, providing the necessary memory resources to handle massive datasets, run multiple virtual machines simultaneously, or accelerate computationally intensive applications. The Z5K42AV kit ensures that systems are equipped with robust, high-capacity memory capable of meeting the most stringent performance requirements.
