HP EM151AVR 2GB Kit (2x1GB) DDR2-667MHz FB-DIMM 2Rx8 CL5 Memory

Product Description

This HP EM151AVR memory kit provides a total of 2GB of RAM, comprised of two 1GB FB-DIMM modules, operating at a DDR2-667MHz speed. FB-DIMMs are a specialized type of memory module commonly found in servers and high-performance workstations, characterized by an Advanced Memory Buffer (AMB) chip. This chip serializes data transfers, reducing the electrical load on the memory controller and enabling higher memory capacities and speeds, which is crucial for enterprise-grade systems. The configuration of 2Rx8 indicates that each 1GB module is dual-ranked, with each rank having an 8-bit data width. This dual-rank design can potentially improve performance by allowing the memory controller to access different ranks independently. The CAS Latency (CL) of 5 signifies the number of clock cycles required for the memory to respond to a column read command, offering a balance between speed and stability for server operations. As ECC Registered memory, these modules incorporate Error-Correcting Code (ECC) to detect and correct single-bit errors, enhancing data integrity and system reliability. The registered nature of the modules further reduces the load on the memory controller, supporting larger memory configurations. The EM151AVR is intended for HP server platforms that specifically support DDR2 FB-DIMM memory, ensuring compatibility and optimal performance for critical business applications.
