Overview of the HPE Memory Module
The HPE 726718-B21 is an 8GB DDR4 SDRAM memory module for servers. It's a registered 288-pin RDIMM (Registered Dual Inline Memory Module) with ECC (Error-Correcting Code) and operates at a speed of 2133MHz. This memory module is designed for use in HPE (Hewlett Packard Enterprise) servers, and it has a CL (CAS Latency) of 15 and a voltage rating of 1.2V.
In this article, we will provide a detailed explanation of the features and specifications of the HPE 726718-B21 memory module.
DDR4 SDRAM (Double Data Rate 4 Synchronous Dynamic Random-Access Memory) is the fourth generation of SDRAM technology. DDR4 memory provides higher performance and efficiency compared to its predecessor, DDR3. It has a lower power consumption, which reduces the heat generated by the server and improves its reliability.
DDR4 memory is designed for use in modern servers, which require high-speed memory to handle large amounts of data. The HPE 726718-B21 is a DDR4 memory module that is compatible with HPE servers.
Registered Dual Inline Memory Module (RDIMM)
The HPE 726718-B21 is a registered dual inline memory module (RDIMM). RDIMMs are a type of memory module that provides a buffer between the memory controller and the memory chips. This buffer helps to reduce the electrical load on the memory controller and improves the reliability of the memory system.
RDIMMs are designed for use in servers and workstations, where large amounts of memory are required. They provide higher capacity and better reliability than unbuffered memory modules.
Error-Correcting Code (ECC)
The HPE 726718-B21 memory module has ECC (Error-Correcting Code) capabilities. ECC is a type of memory technology that can detect and correct errors in the memory system. This is important in servers and workstations, where data integrity is critical.
ECC memory modules have an additional memory chip that stores parity bits. These bits are used to detect and correct errors in the memory system. ECC memory modules provide higher reliability than non-ECC memory modules.
Single Rank Memory Module
The HPE 726718-B21 is a single rank memory module. Memory ranks refer to the number of independent sets of DRAM memory chips on a memory module. A single rank memory module has only one set of memory chips.
Single rank memory modules are preferred for servers and workstations, where memory capacity is important. They provide better performance and capacity than dual rank memory modules.
2133MHz Speed & CAS Latency (CL) 15
The HPE 726718-B21 memory module operates at a speed of 2133MHz. Memory speed refers to the maximum speed at which data can be transferred to and from the memory module. Higher memory speeds provide better performance, but also require higher power consumption and generate more heat.
The 2133MHz speed of the HPE 726718-B21 memory module provides a balance between performance and power consumption. It's a suitable choice for servers and workstations that require high-speed memory.
The HPE 726718-B21 memory module has a CAS latency (CL) of 15. CAS latency is the time delay between the memory controller sending a request for data and the memory module providing the data. Lower CAS latencies provide better performance, but also require higher power consumption and generate more heat.
A CL of 15 is a standard latency for DDR4 memory modules. It provides a balance between performance and power consumption, making it a suitable choice for servers and workstations.
