Product overview for the HPE 879527-091

In the realm of server hardware, memory plays a critical role in ensuring optimal performance and reliability. One such memory module that has gained attention is the HPE 879527-091 16GB DDR4 Memory Kit. In this comprehensive guide, we will delve into the key aspects of this memory kit, breaking down its specifications, features, and applications.

Overview of HPE 879527-091 16GB DDR4 Memory Kit

The HPE 879527-091 is a 16GB DDR4 memory module designed for servers. Let's break down the key components of its nomenclature to better understand its specifications:

  • Capacity: The memory module has a capacity of 16 gigabytes (GB), indicating the amount of data it can store and process.
  • Type: It belongs to the DDR4 (Double Data Rate 4) category, which is the fourth generation of DDR Synchronous Dynamic Random-Access Memory (SDRAM).
  • Configuration: The module operates in a 2rx8 configuration, signifying the arrangement of its memory chips. In this case, it is a dual-rank module with eight memory chips.
  • Speed: The DDR4-2666 specification denotes the memory's operating speed, with a frequency of 2666 megahertz (MHz). This parameter is crucial for determining the data transfer rate.
Form Factor

The HPE 879527-091 memory module adheres to the standard 288-pin design. This form factor is commonly used in server environments and ensures compatibility with a wide range of server systems.

Unbuffered Design

This memory kit features an unbuffered design, which means it does not incorporate any additional buffers for data transmission. Unbuffered memory is known for its simplicity and lower latency, making it suitable for applications where speed is of the essence.

Performance Specifications CAS Latency (CL)

The CAS latency is denoted by CL19 in the HPE 879527-091 memory kit. CAS latency is a measure of the delay between the memory controller requesting data and the actual delivery of the data. A lower CAS latency is generally associated with better performance.

Data Transfer Rate

With a DDR4-2666 specification, this memory module achieves a data transfer rate of 2666 MT/s (mega-transfers per second). This higher transfer rate contributes to improved overall system performance, especially in memory-intensive tasks.

Server Compatibility

The HPE 879527-091 memory kit is explicitly designed for server environments. It is essential to ensure compatibility with specific server models and configurations before installation. Hewlett Packard Enterprise (HPE) provides compatibility lists and guidelines to assist users in selecting memory modules suitable for their servers.

Use Cases and BenefitsServer Performance Enhancement

Upgrading server memory is a common practice to enhance overall system performance. The addition of the HPE 879527-091 16GB DDR4 memory kit provides servers with increased capacity and improved data transfer rates, resulting in faster response times for applications and reduced latency.

Multitasking and Virtualization

Servers often handle multiple tasks simultaneously, including virtualization. Virtualized environments benefit significantly from ample and fast memory, and the 16GB capacity coupled with DDR4-2666 speed makes this memory kit suitable for such demanding scenarios.

Reliability and Stability

HPE is a renowned name in the server hardware industry, and its memory modules undergo rigorous testing to ensure reliability and stability. The 879527-091 memory kit is no exception, assuring businesses of robust performance in critical server operations.


Installing the HPE 879527-091 memory kit follows standard procedures for memory modules. Users should refer to the server's documentation for specific instructions on locating and accessing memory slots. The module is inserted into an available DIMM (Dual Inline Memory Module) slot on the server's motherboard.


While the memory module itself does not require extensive configuration, server administrators should verify that the server's firmware and BIOS are up-to-date. Some servers may require specific configurations in the BIOS to recognize and utilize the new memory capacity fully.

Warranty and Support

HPE typically provides a warranty for its hardware products, including memory modules. Users should check the warranty terms and conditions to understand the coverage provided. Additionally, HPE's customer support services are available to assist users with any queries or issues related to their memory modules.
