Superior Server Performance By combining a speed of 21333MHz and a bandwidth rate of 17066MB/s, this HP, 64GB, PC4-17000P, quad rank server memory kit is able to operate with superior performance capabilities. HP have designed the worlds most innovative technology solutions since 1939, continually reinventing what it means to be a premium technology supplier and pushing the limits of technology design. Vital Memory Technology: DDR4 DDR4 combines outstanding speed and power usage capabilities to create a ground- breaking revolution in memory technology. By increasing the prefetch length, you can now take advantage of a 50% increase in the rate at which information travels across the data bus enabling unparalleled bandwidth rates. Power usage capabilities have been boosted thanks to a reduction in voltage rates from 1.5v to 1.2v ultimately providing operational cost savings. Strengthen Your Data Integrity ECC (error- correcting code) strengthens your data integrity through the instantaneous identification and removal of the most common types of internal data corruptions. This server memory kit is registered (buffered) and this means that a register is situated between the DRAM modules, here, it feeds constancy to the individual modules which then saturates the total system.
