Description
Product overview of the HP 495604-S21
The 495604-S21 memory module is a high-performance memory module made by HP that is designed specifically for use in servers. The memory module has a capacity of 64GB and a clock speed of 667MHz. It is also designed with fully buffered, registered, and ECC features to enhance its performance and reliability.
In this article, we will explain in detail what each of these features means and how they contribute to the performance and stability of a server system.
Capacity and Clock Speed
The 495604-S21 memory module has a capacity of 64GB, which is a significant amount of memory. This is particularly important for servers, which often need to handle large amounts of data from multiple users or applications simultaneously.
In addition to its high capacity, the memory module also has a clock speed of 667MHz. Clock speed is the rate at which a computer’s central processing unit (CPU) accesses data from memory. A higher clock speed generally means that data can be accessed more quickly, which can help to improve the overall performance of a server.
Fully Buffered and Registered Features
The 495604-S21 memory module is designed with fully buffered and registered features. Fully buffered memory, also known as fully buffered dual in-line memory module (FB-DIMM), is a type of memory that uses a buffering chip to improve signal quality and reduce the chance of errors.
Registered memory, also known as registered dual in-line memory module (RDIMM), is a type of memory that includes an additional register between the memory controller and the memory chips. This can help to reduce electrical load and improve signal quality.
Both of these features are important for servers, which may be processing large amounts of data at once. By improving signal quality and reducing errors, fully buffered and registered memory can help to improve overall system performance and reduce the risk of crashes or other issues.
ECC (Error-Correcting Code)
The 495604-S21 memory module is designed with error-correcting code (ECC) features. ECC is a type of memory that can detect and correct errors that occur during data transmission. This is particularly important for servers, which may be processing critical data that must be accurate and reliable.
ECC memory works by adding an extra bit to each memory cell. This extra bit is used to store a parity check code that can be used to detect errors. If an error is detected, the ECC memory can correct it automatically, without the need for user intervention.
DDR2 SDRAM DIMM
The 495604-S21 memory module has a DDR2 SDRAM DIMM form factor. DIMM is a type of memory module that is commonly used in desktop and server computers. DDR2 SDRAM is a type of synchronous dynamic random-access memory (SDRAM) that is used in many older computers.
Although DDR2 SDRAM is not the latest or fastest type of memory, it is still a reliable and efficient option for many server applications. It offers faster clock speeds and higher data transfer rates than previous generations of SDRAM, and it is also more power-efficient than older memory types.
Overall, the 495604-S21 memory module is a high-quality memory module made by HP that is designed specifically for use in servers. With its large capacity, high clock speed, and advanced features like fully buffered, registered, and ECC memory, it is an excellent choice for servers that require high performance and reliability. Whether you are building a new server system or upgrading an existing one, the 495604-S21 memory module is an excellent option to consider.
