Description
The Lenovo 01KR375 is a high-capacity 128 Gigabyte (GB) DDR4 memory module, engineered for demanding enterprise environments. It operates at a speed of 2666MHz, identified by the PC4-21300 standard, providing significant bandwidth for data-intensive applications. As a Registered DIMM (RDIMM), it incorporates an onboard register that buffers command and address signals, reducing the electrical load on the memory controller. This feature is essential for systems requiring large amounts of memory, ensuring signal integrity and stability. This module utilizes DDR4 technology, which offers improved performance, lower power consumption, and higher densities compared to previous DDR generations. The 8Rx4 rank configuration signifies an advanced memory organization, with eight ranks, each composed of four data channels. This configuration is typically found in high-density modules designed to maximize the memory capacity within a server or workstation. With a CAS Latency (CL) of 19, the Lenovo 01KR375 balances its substantial capacity and speed with efficient operation. This module is ideal for servers, high-performance computing, and data analytics platforms where maximum memory capacity and reliable performance are critical requirements. Its 288-pin form factor is standard for DDR4 DIMMs.
