HP 16GB 647901-B21 (1x16GB) Dual RankPC3-10600R (DDR3-1333MHz)RegCAS-9 LV (G8 Series)

The HP 647901-B21 is a high-performance 16GB DDR3 Registered DIMM (RDIMM) designed specifically for HP ProLiant Gen8 servers. Operating at 1333MHz and supporting ECC functionality, this memory module enhances server performance, improves stability, and ensures data integrity in mission-critical environments. With dual rank x4 configuration and low-voltage operation (1.35V), it delivers both efficient power usage and reliable memory bandwidth, making it ideal for enterprise-level virtualization, database workloads, and data center applications.

Product Features

16GB Server-Grade Memory Capacity Delivers a substantial 16GB of memory, ideal for expanding system capabilities and improving performance in virtualized and enterprise computing environments. DDR3-1333MHz Speed Operates at a clock speed of 1333MHz (PC3-10600) to support fast data transfer and smooth multitasking for demanding server operations. Dual Rank x4 Configuration Includes two sets of DRAM chips for improved memory density and optimized data throughput, particularly beneficial in multi-module configurations. Registered ECC Memory Supports error correction (ECC) to automatically detect and correct memory errors, improving system reliability and uptime in mission-critical tasks. Low Voltage Design Runs at 1.35V (PC3L), reducing power consumption and heat generation compared to standard 1.5V DDR3 memory—ideal for energy-conscious data centers. Engineered for HP ProLiant Gen8 Servers Fully tested and validated under HP SmartMemory standards to ensure compatibility, performance, and reliability in supported server systems.
