Description
Product Information
The HPE 862974-B21 is a high-performance memory module designed for servers. It is an 8GB (1x8gb) module with a clock speed of 2400MHz and a latency of CL17. The module uses unbuffered DDR4 SDRAM technology, which provides fast data transfer rates and low power consumption. This article will provide a detailed explanation of the key features of the HPE 862974-B21 memory module.
Memory Module Basics
Memory modules are essential components of modern computer systems. They are used to store and retrieve data quickly and efficiently. A memory module consists of a series of memory chips, which are organized into ranks and banks. The number of ranks and banks on a memory module determines its capacity and performance.
The HPE 862974-B21 memory module is a single-rank module, meaning that it has one set of memory chips. This configuration is ideal for servers because it provides better performance and reliability than dual-rank or quad-rank modules.
Clock Speed and Latency
The clock speed of a memory module determines how quickly it can transfer data. The HPE 862974-B21 memory module has a clock speed of 2400MHz, which means it can transfer data at a rate of 2400 million cycles per second. This high clock speed makes the module ideal for servers that require fast data transfer rates.
Latency is the amount of time it takes for a memory module to respond to a data request. The lower the latency, the faster the module can retrieve data. The HPE 862974-B21 memory module has a latency of CL17, which is relatively low. This low latency means that the module can quickly respond to data requests, making it ideal for high-performance server applications.
DDR4 SDRAM Technology
The HPE 862974-B21 memory module uses DDR4 SDRAM technology, which is the latest generation of Synchronous Dynamic Random Access Memory (SDRAM). DDR4 SDRAM provides several key benefits over previous generations, including increased data transfer rates, improved power efficiency, and higher capacities.
One of the primary advantages of DDR4 SDRAM is its higher data transfer rates. DDR4 SDRAM can transfer data at rates up to 3200MHz, which is twice as fast as DDR3 SDRAM. This high data transfer rate makes DDR4 SDRAM ideal for high-performance server applications.
DDR4 SDRAM also uses less power than previous generations, making it more energy-efficient. The HPE 862974-B21 memory module operates at a voltage of 1.2V, which is lower than the 1.5V used by DDR3 SDRAM. This lower voltage means that DDR4 SDRAM consumes less power, which can lead to significant energy savings for server applications.
ECC and Unbuffered
The HPE 862974-B21 memory module uses Error Correcting Code (ECC) technology, which provides an extra layer of data protection. ECC works by detecting and correcting errors that occur during data transfer. This extra level of protection is essential for servers because data integrity is critical in server applications.
The HPE 862974-B21 memory module is also unbuffered, which means that it does not have a register between the memory controller and the memory chips. Unbuffered modules have lower latency and are less expensive than buffered modules, making them an ideal choice for servers.
288-Pin UDIMM Standard Memory Module
The HPE 862974-B21 memory module is a 288-pin Unbuffered Dual In-Line Memory Module (UDIMM). UDIMMs are the most common type of memory module used in desktops and servers. The 288-pin configuration provides a high degree of compatibility with most modern motherboards and servers.
