Description
The Lenovo 01KR253 is a 16GB DDR4 Registered DIMM (RDIMM) memory module engineered to meet the rigorous demands of modern enterprise computing. Operating at a frequency of 2666MHz, this module provides substantial bandwidth crucial for memory-intensive applications, virtualization, and large datasets. The RDIMM format includes an onboard register that buffers data signals, reducing electrical load on the memory controller and enabling higher memory capacities and improved stability in server environments. This module features a 2Rx8 configuration, indicating it is dual-ranked with an x8 data width per rank. This configuration can offer performance benefits in certain scenarios by allowing the memory controller to access different ranks concurrently. The CAS Latency (CL) of 19 signifies the number of clock cycles required to access a specific column address, a key factor in overall memory responsiveness. As an ECC (Error-Correcting Code) memory module, the 01KR253 can detect and correct single-bit errors, significantly enhancing data integrity and system reliability, which is paramount in mission-critical server operations. Specifically designed and tested for Lenovo systems, the 01KR253 ensures seamless integration and optimal performance. Upgrading or populating systems with these modules allows for increased multitasking capabilities, faster application load times, and improved overall system responsiveness. It is an ideal component for servers and workstations requiring robust and reliable memory solutions to handle demanding workloads and ensure continuous operation.
