Product Specifications to HPE 867855-B21 16GB DDR4 Memory

The HPE 867855-B21 16GB DDR4 memory module is a high-quality component designed for use in enterprise-level servers and workstations. It is manufactured by Hewlett-Packard Enterprise (HPE), a leading provider of enterprise-class hardware and software solutions. This memory module is part of the HPE SmartMemory portfolio, which ensures high reliability, compatibility, and performance in HPE servers.

In this article, we will explore the features and specifications of the HPE 867855-B21 16GB DDR4 memory module in detail.

Capacity and Type of the Memory

The HPE 867855-B21 memory module has a capacity of 16GB, which means that it can store up to 16 gigabytes of data. This is a significant amount of memory, which is useful for running large applications and databases that require high memory bandwidth. The 16GB capacity is also suitable for virtualization and other memory-intensive workloads.

The memory type used in this module is DDR4, which is the latest standard in memory technology. DDR4 memory has several advantages over its predecessor, DDR3, including faster speeds, lower power consumption, and increased memory capacity. DDR4 memory is also more reliable, with error-correcting code (ECC) and other features that improve data integrity.

Clock Speed of the Memory

The HPE 867855-B21 memory module has a clock speed of 2666MHz, which means that it can perform up to 2666 million cycles per second. This clock speed is higher than the industry standard of 2133MHz for DDR4 memory, which means that the HPE memory module can provide better performance and faster data transfer rates.

The clock speed of the memory is an important factor in determining the overall performance of a system. The faster the memory, the faster the system can perform tasks and transfer data between the processor and the memory. The 2666MHz clock speed of the HPE 867855-B21 memory module makes it an ideal choice for high-performance computing environments.

Memory Rank and Form Factor

The HPE 867855-B21 memory module has a single rank, which means that it has a single set of memory chips on the module. A single rank memory module has better performance than a dual rank memory module because it has fewer memory chips to access. This means that the system can access data more quickly, which improves overall performance.

The form factor of the HPE 867855-B21 memory module is registered dual in-line memory module (RDIMM). RDIMMs are a type of memory module that use a buffer to reduce electrical load and improve signal integrity. This makes RDIMMs more reliable and compatible with a wider range of servers and workstations.

ECC and Voltage of the Memory

The HPE 867855-B21 memory module uses ECC, which is a feature that checks for and corrects errors in memory. ECC is important in enterprise-level servers and workstations because it ensures data integrity and reduces the risk of data corruption. ECC is especially important for critical applications that require high levels of reliability and availability.

The voltage of the HPE 867855-B21 memory module is 1.2 volts, which is the standard voltage for DDR4 memory. The low voltage of DDR4 memory reduces power consumption and heat generation, which improves system performance and reliability.

Memory Compatibility and Warranty

The HPE 867855-B21 memory module is compatible with a wide range of HPE ProLiant Gen9 and Gen10 servers and workstations. HPE SmartMemory technology ensures that the memory module is fully compatible and optimized for HPE servers, providing maximum performance and reliability.
