HP M4Z04AAR 64GB DDR4-2133MHz LRDIMM 4Rx4 CL15 Memory

Product Description

The HP M4Z04AAR is a high-capacity 64GB DDR4 Load-Reduced DIMM (LRDIMM) module, specifically designed for enterprise servers that require maximum memory capacity and bandwidth. Operating at a speed of 2133MHz (PC4-17000), this module is suitable for memory-intensive applications such as large-scale virtualization, in-memory databases, and complex scientific simulations. LRDIMMs utilize a memory buffer chip that isolates the memory controller from the memory modules, significantly reducing the electrical load and allowing for higher memory densities and more modules per channel compared to RDIMMs. This module features a 4Rx4 organization, indicating it is a quad-rank (four ranks) DIMM, with each rank having a data width of x4. This high rank count is characteristic of high-capacity LRDIMMs and is designed to maximize the memory capacity and bandwidth achievable in compatible server platforms. With a CAS Latency (CL) of 15, it offers a good balance between its substantial capacity, speed, and responsiveness. As an LRDIMM, it inherently supports Error-Correcting Code (ECC), which is critical for detecting and correcting memory errors, thereby ensuring system stability and data integrity in demanding enterprise environments. This HP 64GB DDR4 LRDIMM is an excellent choice for server administrators looking to equip systems with the highest possible memory configurations. Its combination of massive capacity, robust ECC support, and the advanced LRDIMM architecture makes it suitable for the most demanding server workloads. Compatibility with the specific server motherboard and chipset, including support for 4-rank DIMMs and DDR4-2133MHz speeds, is essential for its successful implementation.
