Description
Product Specifications
HPE 726717-B21 is a type of memory module used in computer systems to enhance the system’s performance. It is a DDR4 2133MHz SDRAM that is single rank X8 CL15 ECC registered 288-pin RDIMM memory. In this article, we will explain in detail what each of these terms means and how they impact the performance of the computer system.
DDR4 Memory
DDR4 is a type of memory used in modern computer systems to store and retrieve data. DDR stands for Double Data Rate, which means that the memory can transfer data twice per clock cycle. DDR4 is the fourth generation of DDR memory, and it is faster and more power-efficient than its predecessors.
Clock Speed
The clock speed of a memory module determines how many times per second it can transfer data to and from the computer’s processor. The clock speed of the HPE 726717-B21 memory module is 2133MHz, which means it can transfer data 2,133 million times per second.
SDRAM
SDRAM stands for Synchronous Dynamic Random Access Memory. It is a type of memory that synchronizes with the system clock to transfer data. SDRAM is faster and more efficient than its predecessor, DRAM.
Single Rank
Single rank memory modules have a single set of memory chips that are accessed in parallel. This means that the memory controller can access all the chips simultaneously, which improves the memory’s performance.
X8
X8 is a term used to describe the memory module’s organization. X8 means that each memory chip has 8 data pins, and the memory controller can access 8 bits of data at a time. X8 is also known as a byte lane.
CL15
CL stands for CAS Latency. It is the time delay between the memory controller sending a request for data and the data being available to the controller. The lower the CAS latency, the better the memory’s performance. CL15 means that the memory has a CAS latency of 15 clock cycles.
ECC Registered
ECC stands for Error-Correcting Code. ECC memory is designed to detect and correct errors in the data stored in memory. This is important in critical applications where data accuracy is essential. ECC memory is slower than non-ECC memory, but it provides an extra level of reliability. ECC memory modules are also registered, which means that they have a register chip that acts as a buffer between the memory controller and the memory chips. Registered memory is slower than unbuffered memory, but it provides better stability and reliability.
288-pin RDIMM
RDIMM stands for Registered Dual Inline Memory Module. RDIMM is a type of memory module that uses a register chip to buffer the signals between the memory controller and the memory chips. This reduces the load on the memory controller and improves the memory’s stability and reliability. The HPE 726717-B21 memory module has 288 pins, which is the number of connectors on the module that connect it to the computer’s motherboard.
Compatibility
Before purchasing a memory module, it is essential to check the computer system’s compatibility. The HPE 726717-B21 memory module is compatible with servers and workstations that support DDR4 memory. It is also compatible with systems that support registered and ECC memory.
In Summary, the HPE 726717-B21 memory module is a high-performance memory module designed for critical applications that require high levels of stability and reliability. It is a DDR4 2133MHz SDRAM that is single rank X8 CL15 ECC registered 288-pin RDIMM memory. Each of these terms describes a specific feature of the memory module that impacts its performance. Before purchasing a memory module, it is essential to check the computer system’s compatibility to ensure that the module is suitable
