Product overview for the HPE 868843-001

In the ever-evolving landscape of information technology, server performance is crucial for the smooth functioning of various applications and services. One integral component that significantly influences server performance is the memory module. In this detailed exploration, we will delve into the HPE 868843-001 32GB 2666MHz PC4-21300 CL19 ECC Registered Dual Rank x4 1.2V DDR4 SDRAM 288-pin RDIMM memory module. We'll break down the technical specifications, understand the significance of each parameter, and explore how this memory module contributes to the efficiency of server systems.

Overview of HPE 868843-001 Memory Module DDR4 SDRAM

Dynamic Random Access Memory (DRAM) plays a pivotal role in the storage and retrieval of data in electronic devices. DDR4 Synchronous Dynamic Random Access Memory (SDRAM) is the fourth generation of the DDR SDRAM family and is widely used in modern computing systems. The HPE 868843-001 is a specific variant of DDR4 SDRAM designed for server applications.

Capacity: 32GB (1X32GB)

The memory module boasts a substantial capacity of 32 gigabytes (GB), making it suitable for memory-intensive tasks. The "1X32GB" notation indicates that the module consists of a single 32GB unit.

Speed: 2666MHz

Memory speed, measured in megahertz (MHz), determines how quickly data can be read from or written to the memory module. The HPE 868843-001 operates at a speed of 2666MHz, indicating a high data transfer rate.

CAS Latency (CL): 19

CAS Latency is a critical parameter that influences the memory module's speed. A CL19 rating means that the module takes 19 clock cycles to deliver requested data after receiving the command. Lower CAS Latency values are generally associated with better performance.

ECC (Error-Correcting Code) Registered

Error correction is crucial in server environments where data integrity is paramount. ECC is a mechanism that detects and corrects memory errors, preventing potential data corruption. The "Registered" attribute indicates that the module has a register, which enhances stability and reliability.

Dual Rank x4

The dual-rank configuration signifies how memory banks are organized on the module. Dual rank indicates that there are two sets of memory chips on each side of the module, enhancing memory density. The "x4" notation implies a 4-bit data width per rank.

Voltage: 1.2V

Efficient power usage is essential in server environments to minimize energy consumption and heat generation. The HPE 868843-001 operates at a low voltage of 1.2V, contributing to energy efficiency and thermal management.

Form Factor: 288-pin RDIMM

The form factor and pin configuration are crucial for compatibility with specific server architectures. The 288-pin Registered Dual Inline Memory Module (RDIMM) form factor is designed for servers, ensuring a secure and standardized connection.

Significance of HPE 868843-001 in Server EnvironmentsEnhanced Server Performance

The high capacity (32GB) and fast speed (2666MHz) of the HPE 868843-001 contribute to enhanced server performance, allowing for quick and efficient data processing. This is particularly beneficial for applications that require large datasets to be stored and accessed rapidly.

Reliability Through ECC

In server environments, data integrity is non-negotiable. The ECC feature of the HPE 868843-001 ensures that errors, if any, are detected and corrected in real-time. This is crucial for preventing data corruption and maintaining the reliability of stored information.

Stability with Registered Design

The "Registered" attribute in the memory module adds a register between the memory module and the memory controller. This register helps in reducing the electrical load on the memory controller, contributing to system stability, especially in configurations with multiple memory modules.

Optimal Power Usage

Efficient power usage is a key consideration in data centers and server rooms. The low operating voltage of 1.2V in the HPE 868843-001 minimizes power consumption, which is essential for achieving energy efficiency and reducing overall operational costs.

Memory Density with Dual Rank Configuration

The dual-rank configuration enhances memory density, allowing for the storage of more data in a given physical space. This is advantageous in servers with limited memory slots, as it enables the accommodation of larger memory capacities without sacrificing reliability or performance.


Proper installation is critical for the optimal functioning of any memory module. The 288-pin RDIMM form factor of the HPE 868843-001 follows industry standards, and installation should align with the server's memory slot configuration. Referencing the server's documentation is essential for correct installation.

System Configuration Considerations

System administrators and IT professionals should consider the overall system configuration when incorporating the HPE 868843-001 memory module. This includes factors such as the existing memory modules, processor capabilities, and operating system requirements.
