Product overview for the HP 647899-B21

In the ever-evolving landscape of technology, servers play a crucial role in facilitating the smooth functioning of various applications and services. One key component that directly influences a server's performance is its memory module. This article delves into the details of the HP 647899-B21 8GB (1X8GB) 1600MHz PC3-12800 CL11 ECC Registered Single Rank DDR3 SDRAM DIMM Memory Module designed for servers.

Overview of HP 647899-B21 Memory Module

The HP 647899-B21 is a memory module specifically crafted for server environments. It comes with a capacity of 8GB, providing ample space for data storage and processing. The DDR3 SDRAM technology ensures high-speed data transfer, and the ECC (Error-Correcting Code) feature enhances the reliability of the module by detecting and correcting memory errors.

Key Specifications

The 8GB capacity of this memory module is ideal for handling a wide range of server workloads, from basic tasks to more resource-intensive applications. b. Speed: With a speed of 1600MHz, the module enables swift data access and transfer, contributing to improved server performance. c. Type: The DDR3 SDRAM type signifies that this module operates based on the Double Data Rate 3 synchronous dynamic random-access memory technology, a widely used standard for server memory.d. ECC and Registered: The ECC and Registered features are crucial for servers where data accuracy is paramount. ECC detects and corrects single-bit errors, while Registered (also known as buffered) memory provides stability by minimizing the electrical load on the memory controller. e. Single Rank: Being a single-rank module means that it has one set of memory chips on each side of the module. This can impact performance positively in certain server configurations. f. CL11 Latency: The CL11 (Column Address Strobe Latency) value represents the delay between a memory controller requesting data and the data being available. A lower CL value indicates faster data access.

Applications and Use Cases

The HP 647899-B21 memory module is tailored for servers, making it suitable for a variety of applications and use cases: a. Enterprise Servers: In large-scale business environments, where servers handle multiple tasks simultaneously, the high capacity and reliability of this memory module are beneficial. b. Data Centers: Data centers, dealing with massive volumes of information, can leverage the speed and efficiency of this module for seamless operations. c. Virtualization: For virtualized environments, where multiple virtual machines run on a single physical server, the 8GB capacity aids in managing the diverse workloads.d. Critical Applications: Servers hosting critical applications, such as databases or financial systems, benefit from the ECC feature, ensuring data integrity.


Before purchasing, it is crucial to ensure compatibility with the server's existing hardware. The HP 647899-B21 is designed to work seamlessly with compatible systems, but checking the server's specifications is advisable. Installing the memory module typically involves powering down the server, locating the memory slots on the motherboard, and securely placing the module in the designated slot. Following the server's manual is essential for proper.

Performance Enhancement and Reliability

The 1600MHz speed of the HP 647899-B21 contributes to faster data access, reducing latency and enhancing overall server performance. b. ECC for Data Integrity: The Error-Correcting Code feature is crucial for preventing and rectifying memory errors, and ensuring the accuracy and reliability of stored data. c. Registered Memory Stability: The Registered memory technology adds a level of stability to the module by buffering the address and control signals, reducing the load on the memory controller.

Comparison with Other Memory Modules

To make an informed decision, it's essential to compare the HP 647899-B21 with other available memory modules in the market. Factors such as capacity, speed, and features like ECC should be considered to meet specific server requirements.

Potential Challenges and Considerations

High-capacity and ECC features may come at a higher cost compared to standard consumer-grade memory modules. Businesses should weigh the benefits against the budget constraints. b. Compatibility Checks: Server administrators need to ensure compatibility not only with the server model but also with other existing memory modules to avoid potential conflicts. c. Future Expansion: Consider the scalability of the server environment and whether the chosen memory module allows for future expansion if the need arises.
