Product Description
The NEC N84022-037 is a 1GB Fully Buffered DIMM (FB-DIMM) memory module, specifically engineered for server and high-performance workstation environments. This module adheres to the DDR2 standard, operating at a frequency of 667MHz, which corresponds to the PC2-5300F designation. The FB-DIMM architecture incorporates an Advanced Memory Buffer (AMB) chip on each module, which serializes data transfers between the memory controller and the DIMM. This design significantly increases memory bandwidth and allows for a greater number of memory modules per channel compared to traditional unbuffered DIMMs. The module features a 2Rx8 configuration, indicating it is dual-ranked with eight memory chips per rank. This configuration can enhance performance by allowing the memory controller to access different ranks independently, improving efficiency. With a CAS Latency (CL) of 5, it specifies the number of clock cycles required for the memory to respond to a column address command. The standard operating voltage for DDR2 FB-DIMMs is 1.8V, which this module adheres to. FB-DIMMs also inherently support Error-Correcting Code (ECC) functionality, crucial for data integrity in mission-critical applications. Due to the unique nature of FB-DIMMs, they are not compatible with standard desktop motherboards that only support unbuffered DIMMs (UDIMMs) or registered DIMMs (RDIMMs). Systems designed for FB-DIMMs, often older server platforms from manufacturers like Dell, HP, and IBM, utilize this technology to achieve higher memory capacities and bandwidth. The NEC N84022-037 is a specific part number for this type of memory, ensuring compatibility within systems that require it.
