In the realm of server hardware, memory plays a crucial role in ensuring optimal performance and reliability. One noteworthy component in this domain is the HPE 726719-S21 16GB DDR4-2133MHz memory module. In this detailed explanation, we will explore the various aspects of this memory module, shedding light on its specifications, features, and the benefits it brings to server systems.

Overview HPE 726719-S21 Memory Module

The HPE 726719-S21 is a memory module designed for server environments, where stability and efficiency are paramount. It falls under the DDR4 category, denoting the fourth generation of Double Data Rate synchronous dynamic random-access memory. This specific module has a capacity of 16GB, making it suitable for memory-intensive applications and workloads.

Technical Specifications

Type and Capacity

The HPE 726719-S21 memory module belongs to the DDR4 category, which signifies advancements over its predecessor, DDR3. The 16GB capacity indicates a substantial amount of RAM, crucial for handling complex computing tasks and large datasets in a server environment.

Speed and Bandwidth

Operating at a speed of 2133MHz, this memory module provides a quick data transfer rate, enhancing the overall responsiveness of the server. The bandwidth of DDR4-2133 ensures efficient communication between the memory and other components, contributing to a smoother operation.

Form Factor

The module adopts a 288-pin RDIMM (Registered Dual In-Line Memory Module) form factor. This design is common in server-grade memory, offering enhanced reliability through the registration of memory addresses.

ECC (Error-Correcting Code)

Error correction is a critical feature in server memory. The HPE 726719-S21 is equipped with ECC, a mechanism that detects and corrects errors in the data stored in memory. This is crucial for maintaining data integrity, especially in mission-critical applications.


Operating at 1.2 volts, this memory module is energy-efficient. Lower voltage not only reduces power consumption but also minimizes heat generation, contributing to the overall thermal management of the server.

CAS Latency

With a CAS (Column Address Strobe) latency of 15, the HPE 726719-S21 strikes a balance between speed and timing. Lower latency values contribute to faster data access, enhancing overall system performance.

Features of HPE 726719-S21 Memory Module

Server-Grade Reliability

Designed specifically for servers, the HPE 726719-S21 undergoes stringent testing to ensure reliability in demanding environments. Server-grade memory is crucial for maintaining system stability and preventing unexpected failures.

Performance Enhancement

The DDR4-2133MHz speed of this memory module is tailored for server applications that require quick data access and processing. Whether it's handling multiple virtual machines or running data-intensive computations, the module contributes to improved overall performance.

ECC for Data Integrity

The inclusion of ECC is a standout feature. In server environments, data integrity is non-negotiable. ECC not only detects but also corrects errors, ensuring that the data stored in memory remains accurate and dependable.

Energy Efficiency

Operating at 1.2 volts, the HPE 726719-S21 is designed with energy efficiency in mind. In data centers where power consumption is a significant consideration, lower voltage memory modules contribute to a more sustainable and cost-effective operation.

Benefits of 726719-S21 Memory Module in Server Environments

Improved system stability

Server-grade components are engineered to withstand the rigorous demands of continuous operation. The HPE 726719-S21, with its ECC and registered design, enhances system stability by minimizing the risk of data errors and improving memory reliability.

Enhanced Workload Handling

The 16GB capacity and DDR4-2133MHz speed make this memory module well-suited for handling diverse workloads. Whether it's running database applications, virtualization, or high-performance computing tasks, the module contributes to smoother and more responsive server performance.

Reduced Downtime

Error correction capabilities are crucial for preventing system crashes and downtime. The ECC feature in the HPE 726719-S21 actively identifies and rectifies errors, reducing the likelihood of unexpected failures and minimizing disruptions to critical operations.

Energy Savings

The lower operating voltage of 1.2 volts not only reduces power consumption but also contributes to a cooler operating environment. In data centers, efficient thermal management is essential, and the HPE 726719-S21 aids in achieving this by generating less heat.


For organizations planning to scale their server infrastructure, the HPE 726719-S21 provides scalability in terms of both capacity and performance. Adding more modules allows for an increase in total RAM, accommodating the growing needs of expanding server deployments.
