The CISCO UCS-ML-X64G4RS-H-WS is a high-capacity, high-speed 64GB DDR4 memory module specifically designed for Cisco Unified Computing System (UCS) servers to handle workloads requiring maximum memory and throughput performance. Operating at a frequency of 2666 MHz and conforming to the PC4-21300 specification, this Load-Reduced DIMM (LRDIMM) is engineered for environments where memory density and speed are critical for application performance. The quad-rank configuration further enhances performance, allowing for greater data bandwidth and stability in server operations. Operating at a low voltage of 1.2v, it offers an energy-efficient solution that doesn't compromise on performance, making it an ideal choice for data centers looking to optimize their performance per watt. This memory module is especially suitable for virtualization, large database applications, and high-performance computing environments.
