Description
The Lenovo 02JG674 is a high-capacity 64GB DDR4 Registered DIMM (RDIMM) module, engineered to provide exceptional memory performance and capacity for advanced Lenovo server platforms. Operating at a robust 2933MHz frequency (PC4-23466), this module delivers high bandwidth essential for demanding enterprise workloads. It operates at the standard DDR4 voltage of 1.2V, contributing to energy efficiency. The module features a CAS Latency (CL) of 21, which dictates the timing for data retrieval operations, balancing speed with system stability. This memory module is configured as 2 ranks x 4 bits (2Rx4). The dual-rank design typically offers performance advantages in servers by allowing the memory controller to access different ranks independently, potentially increasing throughput. The '4 bits' refers to the data width of the individual memory chips within the rank. As an RDIMM, it includes an onboard register that buffers command and address signals, reducing the electrical load on the memory controller. This feature is critical for supporting large memory capacities and ensuring signal integrity in multi-processor or high-density memory configurations. Specifically validated for use in Lenovo servers, the 02JG674 ensures seamless integration and reliable operation within the Lenovo ecosystem. It is imperative for IT professionals to verify compatibility with their specific server model and configuration to ensure optimal performance and stability. This 64GB DDR4 RDIMM is an ideal choice for memory-intensive applications such as large-scale virtualization, complex database operations, big data analytics, and high-performance computing environments where substantial memory resources are paramount.
