NEC N84022-038 2GB DDR2-667MHz FB-DIMM 2Rx8 CL5 Memory

Product Description

The NEC N84022-038 is a 2GB memory module specifically designed for server and workstation environments that utilize the DDR2 Fully Buffered DIMM (FB-DIMM) architecture. FB-DIMMs were introduced to overcome the limitations of traditional unbuffered memory, particularly in systems requiring a large number of memory modules. They feature an Advanced Memory Buffer (AMB) chip on the module itself, which serializes data traffic between the memory controller and the DRAM chips. This buffering significantly increases memory bandwidth and allows for a greater number of DIMMs to be populated on a single memory channel, making it ideal for memory-intensive applications and high-density server configurations. This particular module operates at a speed of 667MHz, corresponding to PC2-5300F specifications, and features a CAS Latency (CL) of 5. The 2Rx8 designation indicates that it is a dual-rank module with eight memory chips per rank. Dual-rank modules can offer performance benefits in certain workloads by allowing the memory controller to access data from different ranks more efficiently. The FB-DIMM form factor is physically distinct from standard DIMMs and is not interchangeable with unbuffered or registered DIMMs (RDIMMs). As a component designed for enterprise-grade systems, the NEC N84022-038 is built for reliability and stability under demanding conditions. These modules typically incorporate Error-Correcting Code (ECC) functionality, which detects and corrects single-bit memory errors, crucial for preventing data corruption and system crashes in mission-critical applications. This 2GB FB-DIMM is a specific upgrade or replacement part for servers and workstations that are compatible with this advanced memory technology.
