HP 8GB (1X8GB) 2RX4 PC3-10600R-9 DDR3-1333MHZ Memory Kit - 593913-B21

This dual rank 8GB HP server memory module runs at 1333MHz and features a 10666.67MB/s bandwidth on a DDR3 interface. Formed in 1939, HP are frequently touted as market leaders when it comes to design and manufacture of servers and related components, with their memory technology regularly pushing performance boundaries.

DDR3 memory offers numerous improvements over DDR2, such as its ability to transfer data at twice the rate of its predecessor and its prefetch length, which is also double that of DDR2 at 8 bits. It also offers reduced voltage from 1.8v-1.9v to 1.35v-1.5v, markedly reducing the operating cost across multiple servers.

As well as featuring ECC (error-correcting code) which detects and corrects the most common kinds of internal data corruption, this HP server memory module is also registered (also known as buffered) which encourages stability in the individual modules via the addition of a register between the DRAM modules, and therefore improves stability in the system as a whole.
