State-of-the-art Performance A speed of 1600MHz and a bandwidth rate of 10667MB/s allows this HP PC3L-12800R 16GB, dual rank server memory kit to reach state-of the-art performance levels. HP has delivered the highest quality products since 1939 and continues to design the most innovative technology solutions today, a clear industry leader. DDR3: Unlock Optimum Server Potential Unlock optimum server potential with DDR3 technology. An increase in prefetch length from 4 to 8 bits represents double the speed at which information flows across the data bus. Lower voltage levels, dropping from 1.8v-1.9v to 1.35v, ensures that this low voltage unit delivers outstanding savings in operational costs and conserves energy with maximum efficiency. Maintain Data Integrity ECC (error- correcting code) maintains data integrity via the constant monitoring and analysis of the most common types of interior corruptions, consequently acting to remove threats instantly. This HP server memory kit is registered (buffered), the register is situated between the DRAM modules which gives stability firstly to the individual modules and then, secondly, the overall system.
