The Kingston KVR21R15S8/4 is a 4GB DDR4 2133MHz ECC Registered DIMM server memory module. This module is designed for use in servers and workstations requiring high levels of data integrity and stability. The ECC (Error-Correcting Code) functionality detects and corrects internal data errors, helping prevent system crashes and data corruption. The registered design adds signal stability for reliable operation in demanding environments.

Applications:

• Servers: Suitable for use in various server applications, including web servers, database servers, and file servers.
• Workstations: Ideal for professional workstations used for tasks such as video editing, 3D modeling, and scientific simulations.
• Virtualization Environments: Supports stable and reliable operation in virtualized environments.
• Data Centers: Used in data centers to ensure data integrity and system uptime.
• High-Performance Computing (HPC): Provides the necessary memory capacity and error correction for HPC applications.

Features:

• 4GB Capacity: Offers a 4GB memory capacity for running server and workstation applications.
• DDR4 Technology: Utilizes DDR4 technology for increased speed, bandwidth, and energy efficiency compared to DDR3.
• 2133MHz Clock Speed: Operates at a clock speed of 2133MHz, enabling fast data transfer rates.
