Lenovo 01PE562 64GB DDR4-2666MHz RDIMM 4Rx4 CL19 Memory

Product Description

The Lenovo 01PE562 is a high-density 64GB DDR4 Registered DIMM (RDIMM) module, engineered to meet the demanding memory requirements of enterprise-grade Lenovo servers. This module operates at a speed of 2666MHz, corresponding to a PC4-21300 designation, providing substantial bandwidth for data-intensive tasks. It utilizes the standard 1.2V power supply for DDR4 memory, ensuring compatibility and power efficiency. The module features a CAS Latency (CL) of 19, indicating the number of clock cycles required to access data, which contributes to its overall performance profile. This memory module is configured as 4 ranks x 4 bits (4Rx4). The quad-rank design offers increased memory bandwidth and capacity density compared to single or dual-rank modules, making it suitable for systems that require the maximum possible memory footprint. The '4 bits' refers to the data width of the individual memory chips. As a Registered DIMM, it incorporates an onboard register that buffers command and address signals, reducing the electrical load on the memory controller. This is crucial for maintaining signal integrity and enabling the installation of a large number of memory modules in high-end servers. Specifically designed and validated for Lenovo servers, the 01PE562 ensures seamless integration and reliable operation within the Lenovo ecosystem. It is essential for IT administrators to confirm compatibility with their specific server model and configuration to achieve optimal performance and stability. This 64GB DDR4 RDIMM is an excellent choice for memory-intensive applications such as large-scale virtualization, complex database management, big data analytics, and high-performance computing environments where maximum memory capacity and efficient data access are critical.
