Product overview for the HP 647899-B21

In the fast-paced world of technology, server memory plays a crucial role in ensuring optimal performance and reliability. One such component is the HP 647899-B21 8GB DDR3 SDRAM Dimm Memory Module. In this detailed guide, we will delve into the intricacies of this memory module, exploring its specifications, features, and benefits.

Understanding the Basics

The HP 647899-B21 is an 8GB DDR3 SDRAM Dimm memory module designed specifically for server applications. Let's break down the key components of its nomenclature to gain a better understanding:

Capacity and Configuration

  • The "8GB" denotes the module's storage capacity, indicating that it can store and retrieve 8 gigabytes of data.
  • The "1X8GB" signifies that this is a single-module configuration, with a total capacity of 8GB.

Memory Speed

  • "1600MHz" refers to the memory module's speed, indicating that it operates at a frequency of 1600 megahertz. This high speed is crucial for quick data access and transfer within the server.

Memory Type and Class

  • "PC3-12800" specifies the memory type and class. In this case, it is a DDR3 (Double Data Rate 3) module, and "PC3-12800" denotes the peak bandwidth of the memory, indicating it can transfer 12,800 megabytes per second.

Error-Correcting Code (ECC) and Registered Design

  • "CL11 ECC Registered" highlights two critical features. ECC (Error-Correcting Code) is a mechanism that detects and corrects errors in data, ensuring data integrity. The term "Registered" refers to the use of a register to control the flow of data within the memory module, enhancing stability in server environments.


  • "Single Rank" specifies the organization of memory chips on the module. Single-rank modules have memory chips on one side, making them suitable for systems with limited DIMM slots.

Features and Benefits

Reliable Performance in Server Environments

  • The ECC feature ensures that the memory module can detect and correct single-bit errors, crucial for maintaining data accuracy in server applications where reliability is paramount.
  • The Registered design enhances stability by reducing electrical load and signal integrity issues, making it ideal for enterprise-level server deployments.

High-Speed Data Transfer

  • With a speed of 1600MHz, the HP 647899-B21 facilitates rapid data access and transfer, contributing to overall system responsiveness and performance.

Optimized for DDR3 Architecture

  • As a DDR3 module, the 647899-B21 is designed to work seamlessly with DDR3-based server architectures, ensuring compatibility and efficient operation within such systems.

Space-Efficient Single-Rank Design

  • The single-rank configuration makes this memory module suitable for servers with limited DIMM slots, allowing for efficient use of available space on the server motherboard.
  • The HP 647899-B21 memory module follows industry-standard DIMM form factors, making it compatible with a wide range of server systems that support DDR3 memory.
Compatibility Assurance
  • Before installation, it is essential to verify the compatibility of the module with the specific server model. HP provides detailed compatibility lists and documentation to guide users in selecting the right memory for their servers.
Configuration Considerations
  • System administrators should consider the existing memory configuration and requirements of the server when adding or upgrading memory modules to maintain a balanced and optimized system.
