Product Description
The NEC N8402-019 is a 4GB memory kit designed to enhance the performance and stability of server and workstation systems. This kit comprises two 2GB DDR2 Registered DIMMs (RDIMMs), operating at a speed of 667MHz, often referred to as PC2-5300. Registered DIMMs are crucial for enterprise environments as they include a register that buffers command and address signals, reducing electrical load on the memory controller and allowing for higher memory capacities and improved stability. Each module in this kit is a 2Rx4 configuration, indicating it is dual-rank with four memory chips per rank. This configuration can sometimes offer performance benefits in certain memory access patterns. The CAS Latency (CL) is rated at 5, which is a measure of the delay between the memory controller telling the memory module to access a particular column in a row and the data being available. Lower CL values generally indicate faster performance. This memory kit is specifically suited for systems that support DDR2 RDIMMs and require ECC (Error-Correcting Code) functionality, which is standard for RDIMMs and vital for data integrity in critical applications. The N8402-019 is an ideal upgrade for servers and workstations needing increased memory capacity and the reliability features associated with registered, ECC-enabled memory.
