HP 6478991 8GB DDR3-1600MHz ECC Registered CL11 RDIMM 1R Memory Module

Product Description

The HP 6478991 is an 8GB DDR3 Synchronous Dynamic Random-Access Memory (SDRAM) module designed for server and workstation applications. It operates at a frequency of 1600MHz, providing a substantial bandwidth for data processing and multitasking. This module is a Registered DIMM (RDIMM), which means it includes an onboard register that buffers command and address signals. This buffering reduces the electrical load on the memory controller, allowing for higher memory capacities and improved signal integrity, which is crucial for system stability in enterprise environments. This memory module features Error-Correcting Code (ECC) capabilities, enabling it to detect and correct single-bit errors that can occur during memory operations. ECC memory is vital for maintaining data integrity and preventing system crashes in critical applications where data accuracy is paramount. The CAS Latency (CL) is rated at CL11, indicating the number of clock cycles required for the memory to access a specific column of data. This latency, combined with the 1600MHz speed, offers a balanced performance profile for a wide range of server workloads. The 1R designation signifies that this is a single-rank module. A rank is a block of memory chips that share a common data bus. Single-rank modules are generally less complex and can offer good performance for many applications. This 8GB DDR3 RDIMM is a reliable component for upgrading or populating memory in compatible HP servers and workstations, ensuring efficient operation and data reliability.
