The HPE 16GB 2Rx4 DDR3-1600 PC3L-12800R ECC Registered Memory SK Hynix HMT42GR7AFR4A-PB is a high-reliability enterprise memory module designed for mission-critical server environments that demand stability, efficiency, and consistent performance. Built using premium SK Hynix components and commonly found in HPE ProLiant server configurations, this 16GB DDR3L RDIMM provides an ideal solution for virtualization, database management, cloud infrastructure, and enterprise application workloads.
Featuring a dual-rank 2Rx4 design and operating at 1600MHz (PC3L-12800R), this ECC Registered DIMM delivers fast memory throughput while maintaining exceptional data integrity. Its low-voltage 1.35V DDR3L architecture helps reduce power consumption and thermal output, making it particularly suitable for dense server deployments and energy-conscious data centers.
The HMT42GR7AFR4A-PB-HP incorporates advanced Error-Correcting Code (ECC) technology that automatically detects and corrects memory errors, helping prevent data corruption and improve system uptime. Registered signal processing further enhances memory stability in multi-socket server platforms where large memory capacities are required.
