Memory modules play an important role in the performance of a computer system. They are responsible for storing and retrieving data quickly and efficiently. When it comes to server memory, there are various factors that need to be considered. The HMA42GR7AFR4N-UH 16GB 1x16gb PC4-19200 CAS-17 ECC 2400MHz Dual Rank X4 DDR4 SDRAM Registered 288-Pin RDIMM Memory Module for Server, made by Hynix, is a popular choice among server users. In this article, we will explain the technical specifications of this memory module in simple English.
Capacity of DDR4 SDRAM 288-Pin Reg RAMThe HMA42GR7AFR4N-UH memory module has a capacity of 16GB. This means that it can store up to 16 gigabytes of data. This is a decent amount of memory for a server, and it is suitable for most applications.
Memory Type & SpeedThis memory module uses DDR4 SDRAM technology. DDR4 is the fourth generation of DDR RAM, and it offers improved performance compared to DDR3. It has a higher bandwidth and lower power consumption, which makes it ideal for server applications.
The HMA42GR7AFR4N-UH memory module has a memory speed of 2400MHz. This means that it can transfer data at a rate of 2400 million cycles per second. A higher memory speed translates to faster data transfer rates, which can improve server performance.
CAS Latency & Error-Correcting CodeCAS latency is a measure of the delay between the time a memory controller requests data from memory and the time it receives that data. The HMA42GR7AFR4N-UH memory module has a CAS latency of 17. This means that there is a delay of 17 clock cycles between the time the memory controller requests data and the time it receives that data. A lower CAS latency means faster data transfer, but it is not the only factor that determines the overall performance of a memory module.
ECC stands for Error-Correcting Code. ECC memory is designed to detect and correct errors that occur during data storage or transmission. The HMA42GR7AFR4N-UH memory module is equipped with ECC technology, which makes it more reliable than non-ECC memory modules.
Rank & RegisteredA rank is a group of memory chips that are accessed together by the memory controller. The HMA42GR7AFR4N-UH memory module has a dual rank configuration, which means that it has two groups of memory chips that are accessed together. This can improve memory performance in certain situations.
Registered memory, also known as buffered memory, is a type of memory module that uses a register to control the flow of data between the memory controller and the memory chips. This can improve stability and reliability, especially when using multiple memory modules. The HMA42GR7AFR4N-UH memory module is registered, which makes it more suitable for server applications.
Form FactorThe HMA42GR7AFR4N-UH memory module has a form factor of 288-pin RDIMM. RDIMM stands for Registered Dual Inline Memory Module, and it is a type of memory module that is commonly used in server applications. The 288-pin form factor is also standard for DDR4 memory modules.
