Lenovo 4ZC7A08721 64GB DDR4-2666MHz RDIMM 4Rx4 CL19 Memory

Product Description

The Lenovo 4ZC7A08721 is a high-capacity 64GB DDR4 Registered DIMM (RDIMM) memory module, engineered to meet the rigorous demands of modern server and high-performance computing environments. Operating at a speed of 2666MHz, this module provides a substantial bandwidth for data transfer, crucial for applications that require rapid access to large datasets. The Registered DIMM (RDIMM) architecture includes onboard registers that buffer memory commands and addresses, reducing electrical load on the memory controller and allowing for higher memory capacities and improved stability in multi-processor systems. This specific module features a Quad Rank x4 (4Rx4) configuration. Quad Rank modules offer increased memory density and bandwidth by dividing the memory chips into four ranks, each accessed independently. This configuration is particularly beneficial in servers that support a large number of memory modules, enabling higher overall system memory capacity and potentially improved performance through more efficient utilization of the memory controller's channels. The CL19 CAS Latency indicates the number of clock cycles required to access data, providing a balance between speed and performance for its class. With its substantial 64GB capacity, DDR4 technology, and robust 4Rx4 configuration, the Lenovo 4ZC7A08721 is an ideal choice for memory-intensive applications such as virtualization, large databases, scientific simulations, and data analytics. Its registered nature also implies built-in ECC (Error-Correcting Code) functionality, which detects and corrects single-bit errors, enhancing data integrity and system reliability – a critical requirement for mission-critical server operations.
