HPE 840755-091 PC4-21300 8GB RAM 2666 MHz Cl19 ECC Reg DDR4 New

In the realm of server hardware, memory plays a crucial role in ensuring optimal performance and reliability. One such memory module that has garnered attention is the HPE 840755-091, a PC4-21300 DDR4 module designed for server applications. In this detailed exploration, we will delve into the intricacies of this memory module, breaking down its specifications and shedding light on its significance in server environments.

This indicates the storage capacity of the memory module, which is 8 gigabytes. In server configurations, memory capacity is crucial for handling large datasets and concurrent processes. The 8 Gigabytes capacity of this module indicates the amount of data it can store and process. In server environments, where multitasking and data-intensive applications are commonplace, having an adequate amount of memory is essential for smooth operations.

This module belongs to the DDR4 (Double Data Rate 4) category, which is the fourth generation of DDR Synchronous Dynamic Random Access Memory (SDRAM). DDR4 offers improvements in data transfer rates and power efficiency compared to its predecessors, making it well-suited for modern server architectures.

The speed of a memory module is measured in Megahertz (MHz), and the HPE 840755-091 operates at a frequency of 2666MHz. This speed determines how quickly data can be read from or written to the memory, influencing the overall performance of the server.

The CL19 specification denotes the Column Address Strobe Latency, which is the time delay between the memory controller sending a read command and the data being available. A CL19 latency indicates moderate speed, balancing performance, and stability.

Additionally, this module features Error-Correcting Code (ECC), a crucial capability in server memory. ECC ensures data integrity by detecting and correcting errors that may occur during data transmission. In mission-critical server environments, where data accuracy is paramount, ECC is indispensable.

The term "Registered" signifies that this memory module utilizes a register to temporarily store data before it is transferred to the memory modules. This provides stability and reliability, making it suitable for servers that demand continuous and error-free operation.

The module is also labeled as "Single Rank," indicating that the memory chips are all on one side of the module. Single-rank modules typically provide better performance in certain workloads compared to dual-rank modules.

Operating at 1.2 volts, the HPE 840755-091 is designed with energy efficiency in mind. Lower voltage levels contribute to reduced power consumption, an essential consideration in data centers striving for sustainability and cost-effectiveness.

With a 288-pin RDIMM (Registered Dual Inline Memory Module) form factor, this memory module is designed to be used in servers and workstations that support this specific configuration. The form factor ensures compatibility with a wide range of server architectures.

Now that we've explored the technical specifications of the HPE 840755-091, let's delve into why these features are significant in a server environment.

The 2666MHz speed of this module contributes to improved data transfer rates, enabling servers to handle demanding applications and workloads more efficiently. For tasks such as virtualization, database management, and high-performance computing, a higher memory speed is crucial for optimal performance.

The inclusion of ECC is a critical aspect, especially in servers handling sensitive and mission-critical data. ECC ensures that errors, which can occur due to various factors such as cosmic rays or electrical interference, are detected and corrected in real time. This feature is essential for maintaining data integrity and preventing potential system crashes.

The registered design of this memory module enhances stability during prolonged usage. In server environments where uptime is a priority, having registered memory helps prevent issues like signal degradation that can occur with unbuffered memory modules.

The 288-pin RDIMM form factor ensures compatibility with a wide range of server configurations. This modularity allows for easy integration into existing server setups and facilitates scalability. Server administrators can upgrade the memory capacity by adding more modules without requiring a significant overhaul of the entire system.

Operating at 1.2 volts, the HPE 840755-091 contributes to the overall energy efficiency of a server infrastructure. Lower power consumption not only reduces operational costs but also aligns with sustainability goals in data center management.

Understanding the specific use cases for the HPE 840755-091 helps highlight its versatility and applicability in various server environments.
