Description
The Lenovo 01KR380 is a 16 Gigabyte (GB) DDR4 memory module designed for server and workstation applications. It operates at a speed of 2666MHz, corresponding to the PC4-21300 standard, offering robust performance for various computing tasks. This module is a Registered DIMM (RDIMM), which includes an onboard register to buffer address and command signals. This buffering reduces the electrical load on the memory controller, enabling systems to support higher memory capacities and maintain stability, especially in multi-module configurations. Utilizing DDR4 technology, this memory module provides enhanced bandwidth, lower power consumption, and greater density compared to older DDR generations. The 2Rx8 rank configuration indicates that the module has two ranks, each composed of eight data channels. This is a common and efficient configuration for many server memory applications, balancing capacity and performance. With a CAS Latency (CL) of 19, the Lenovo 01KR380 offers a good balance between speed and responsiveness for its capacity. It is an ideal choice for expanding the memory footprint of servers and workstations, supporting virtualization, databases, and other memory-intensive workloads. The module uses a standard 288-pin DIMM connector for compatibility with DDR4-enabled motherboards.
