Revolutionary System Performance A speed of 1600MHz and a bandwidth rate of 10667MB/s ensures this HP PC3L-12800R 16GB, dual rank server memory kit provides revolutionary server performance. HP has designed superior, reliable products since 1939 and continues to lead the way through the design of the most prescient technology solutions of our time. DDR3: Unleash Maximum Server Potential Unleash your servers full potential with the assistance of DDR3 technology. Dramatic improvements to performance and power usage have resulted in a massive upgrade in memory technology capabilities. A fall in voltage levels from 1.8v- 1.9v to 1.5v means that maximum efficiency and operational savings can be realised. This is combined with a significant enhancement to speed thanks to double the prefetch length, growing from 4 to 8 bits, informational transactions flow through the data bus seamlessly. Optimum Data Integrity ECC (error- correcting code) ensures optimum data integrity through uninterrupted system analysis to combat the most common types of interior data corruptions. This server memory kit is registered (buffered), the buffer is placed within the DRAM modules which consequently gives stability to the individual modules and the overall system.
