Product Description
The HP 6CN90AV memory kit represents an extreme-capacity solution, providing a total of 768GB of DDR4 memory through twelve 64GB Registered DIMM (RDIMM) modules. This kit is engineered for the most resource-intensive enterprise server environments, supporting applications such as massive in-memory databases, large-scale scientific simulations, and extensive virtualization deployments. Operating at a high frequency of 2933MHz, these modules ensure rapid data throughput and minimize latency for computationally demanding tasks. The RDIMM design incorporates registers that buffer memory signals, enhancing system stability and allowing for higher memory densities, which is critical for configurations utilizing all twelve memory slots. The 2Rx4 rank configuration signifies dual ranks per module, each with a 4-bit chip organization, potentially optimizing memory access patterns for compatible server memory controllers. With a CAS Latency of CL21, the kit offers a robust combination of speed and responsiveness suitable for high-performance computing. This memory configuration is typically found in top-tier servers designed for maximum memory capacity and performance. It is imperative to consult the specific server model's documentation to ensure compatibility and to follow recommended population guidelines for achieving the full 768GB capacity reliably.
