With its DDR4 technology, ECC support, and 2133MHz frequency, this kit ensures smooth multitasking, efficient data processing, and long-lasting durability for mission-critical computing environments.
Exceptional Performance with DDR4 Technology
DDR4 memory is a significant leap forward compared to DDR3, providing higher bandwidth, lower power consumption, and improved reliability. The Kingston 16GB DDR4 Kit runs at 2133MHz, allowing faster data transfer rates and seamless system responsiveness. Whether you are running complex applications, managing large databases, or working with virtualization, this module ensures that your system keeps up with heavy workloads.
By leveraging PC4-17000 bandwidth, the Kingston KVR21R15S8K4/16 delivers higher performance than older memory solutions, making it ideal for businesses upgrading their infrastructure or individuals who want their server to operate at maximum efficiency.
Error-Correcting Code (ECC) Reliability
One of the standout features of the Kingston 16GB DDR4-2133MHz Kit is its ECC (Error-Correcting Code) capability. ECC memory automatically detects and corrects common types of data corruption, ensuring data accuracy and reducing the risk of system crashes. This feature is crucial for servers, workstations, and high-performance computing systems that handle sensitive or mission-critical data.
With ECC support, you can confidently run applications like financial systems, medical databases, enterprise-grade servers, or virtualization software without worrying about unexpected downtime caused by memory errors.
Registered DIMM for Enhanced Stability
The Kingston KVR21R15S8K4/16 is a Registered ECC module, meaning it uses a register between the DRAM modules and the system’s memory controller. This design reduces the electrical load on the memory controller and increases stability in systems with multiple memory modules. Registered DIMMs are the preferred choice for enterprise-class servers and workstations where reliability and scalability are paramount.
Energy Efficiency and Lower Power Consumption
Efficiency is as important as performance. The Kingston 16GB DDR4 memory operates at 1.2V, which is lower than DDR3’s standard 1.5V. This results in reduced power consumption, lower heat generation, and overall cost savings—especially beneficial for data centers and servers that run continuously.
The energy efficiency of DDR4 not only reduces operating costs but also contributes to eco-friendly, sustainable computing by minimizing power demands in high-performance environments.
Compatibility and Easy Integration
The Kingston 16GB DDR4-2133MHz Kit is designed for broad compatibility with various server motherboards and enterprise systems. Kingston rigorously tests its memory modules for quality assurance, ensuring hassle-free installation and seamless integration with your existing hardware.
Whether you are upgrading your current setup or building a new server, this kit offers plug-and-play functionality, reducing downtime and ensuring that your system is ready to perform without complications.
