The Hewlett Packard Enterprise 16GB 2Rx4 PC4-2133P-R is a server-grade memory module designed for enterprise computing environments requiring reliable performance and compatibility. This DDR4 memory module operates at 2133 MHz with a PC4-2133P-R specification, featuring a 2Rx4 dual-rank configuration that optimizes data throughput for demanding server applications. With 16 GB capacity, this module provides substantial memory resources for virtualization, database management, and high-performance computing tasks. The module follows industry-standard 288-pin DIMM design and operates at 1.2 V, ensuring energy-efficient performance in compatible HPE server systems. Its error-correcting code (ECC) functionality helps maintain data integrity by detecting and correcting single-bit memory errors, a critical feature for mission-critical server operations. The memory is engineered to meet strict HPE compatibility requirements and undergoes rigorous testing to ensure reliable operation in supported server platforms. The module's construction utilizes quality components and adheres to JEDEC standards for DDR4 memory, providing stable performance across varying environmental conditions. This memory solution is suitable for expanding existing server configurations or building new systems where HPE compatibility and enterprise-grade reliability are priorities. The 2Rx4 organization allows for efficient memory access patterns, while the 2133 MHz speed provides balanced performance for most server workloads. When installing, verify compatibility with specific HPE server models and consult system documentation for proper configuration guidelines. This memory module represents a successor model to previous DDR3 solutions, offering improved performance and efficiency for modern server environments.
