Product overview for the Kingston KVR21R15S4/8

In the fast-paced world of technology, server memory plays a crucial role in ensuring optimal performance and reliability. One notable contender in the realm of DDR4 ECC Registered memory modules is the Kingston KVR21R15S4/8. In this comprehensive review, we will delve into the key features, specifications, and benefits of this 8GB memory module designed for servers.

Overview of Kingston KVR21R15S4/8 Design and Construction

The Kingston KVR21R15S4/8 is a DDR4-2133MHz ECC Registered memory module designed for server applications. With a single-rank configuration and a capacity of 8GB, it meets the demanding requirements of servers, providing both speed and stability. The 288-pin RDIMM form factor ensures compatibility with a wide range of server systems.

Performance Specifications

The memory module operates at a frequency of 2133MHz, making it suitable for handling data-intensive tasks in server environments. The CAS Latency (CL) of 15 ensures quick response times, contributing to overall system efficiency. ECC (Error-Correcting Code) support enhances data integrity, a critical feature for servers where accuracy is paramount.

Key Features

Single Rank

The Kingston KVR21R15S4/8 features a single-rank configuration, meaning that the memory chips are all on one side of the module. This design choice can have implications for memory access times and compatibility with certain server architectures. Understanding the advantages of a single-rank configuration is essential for making informed decisions in server memory selection.

ECC (Error-Correcting Code) Support:

ECC is a crucial feature in server memory modules, providing an extra layer of data integrity by detecting and correcting errors in real-time. The KVR21R15S4/8's ECC support ensures that data transmitted and stored by the server is accurate, reducing the risk of data corruption and system crashes.

Registered DIMM (RDIMM) Form Factor

The 288-pin RDIMM form factor of the Kingston KVR21R15S4/8 is standard for server memory modules. RDIMM modules are equipped with a register, which acts as a buffer between the memory module and the memory controller. This buffering enhances signal integrity and stability, making RDIMMs ideal for high-density server configurations.

DDR4 Technology

Being a DDR4 memory module, the KVR21R15S4/8 benefits from the advancements in-memory technology. DDR4 offers higher data transfer rates, lower power consumption, and improved reliability compared to its predecessors. Server administrators will appreciate the increased bandwidth and efficiency that DDR4 brings to their infrastructure.

Performance Benchmarks

Speed and Latency

The DDR4-2133MHz speed of the KVR21R15S4/8 ensures that data can be processed quickly, catering to the demands of modern server applications. The CAS Latency of 15 strikes a balance between speed and responsiveness, providing an optimal user experience in server environments.

Stability and reliability

In server environments, stability and reliability are paramount. The ECC support and registered design of the KVR21R15S4/8 contribute to error prevention and system stability. These features are particularly crucial in mission-critical applications where system downtime is not an option.


The Kingston KVR21R15S4/8 is designed to be compatible with a wide range of server systems. However, server administrators should verify compatibility with their specific server model and motherboard before making a purchase. Ensuring compatibility is crucial to avoid issues such as system crashes or suboptimal performance.


Installing the KVR21R15S4/8 is a straightforward process that follows standard RDIMM installation procedures. Server administrators should refer to the product manual for detailed instructions. Proper installation is essential for maximizing the performance and reliability of the memory module within the server environment.
