Product Description
The Lenovo 01KR381 is an 8 Gigabyte (GB) DDR4 memory module designed for reliable performance in server and workstation environments. It operates at a speed of 2666MHz, corresponding to the PC4-21300 standard, ensuring efficient data transfer for a wide range of applications. This module is a Registered DIMM (RDIMM), which includes an onboard register that buffers command and address signals. This buffering helps to reduce the electrical load on the memory controller, allowing for greater memory capacity and improved system stability, particularly in systems with multiple memory modules. Leveraging DDR4 technology, this memory module offers advantages such as higher bandwidth, reduced power consumption, and increased density over previous DDR generations. The 1Rx8 rank configuration indicates that the module has a single rank, with eight data channels. This is a standard and versatile configuration suitable for many server and workstation memory requirements. With a CAS Latency (CL) of 19, the Lenovo 01KR381 provides a balanced performance profile for its capacity. It is an excellent choice for general-purpose server and workstation memory upgrades, supporting operating systems, applications, and multitasking. The module uses a standard 288-pin DIMM connector, ensuring compatibility with DDR4-enabled motherboards.
