Product Overview
The 408854R-B21 is a type of computer memory known as RAM. It is manufactured by HP and is designed to work in servers, workstations, and other high-performance computing systems. This RAM module is designed to provide high-speed performance, reliability, and stability for demanding applications.
RAM
Random Access Memory (RAM) is a type of computer memory that stores data and instructions for the CPU to access quickly. It is a temporary storage location for data that is being actively used by the computer. RAM is essential for running programs and applications on a computer.
The 408854R-B21 HP RAM
The 408854R-B21 HP RAM is an 8GB DDR2 SDRAM module with a speed of 667MHz. It is designed to work in systems that support DDR2 SDRAM memory technology and has a memory clock speed of 667MHz. The RAM is also ECC registered, which means that it has error correction capabilities.
ECC Registered
ECC (Error Correcting Code) is a type of memory technology that is designed to detect and correct errors that occur during the memory transfer process. This is important in high-performance computing environments where even small errors can have significant consequences. ECC memory is more reliable than non-ECC memory, which is why it is commonly used in servers and workstations.
240-Pin RAM
The 408854R-B21 HP RAM is a 240-pin module, which means that it has 240 pins on the bottom edge of the module that connect to the motherboard. The number of pins on a RAM module is important because it determines the type of connector that is required on the motherboard.
DDR2 SDRAM
DDR2 (Double Data Rate 2) SDRAM is a type of memory technology that was first introduced in 2003. It is an improved version of DDR SDRAM and is designed to provide faster and more reliable performance. DDR2 SDRAM has a higher memory clock speed and a lower power consumption than DDR SDRAM.
667MHz Speed
The 667MHz speed of the 408854R-B21 HP RAM refers to the memory clock speed. Memory clock speed is the rate at which the RAM can transfer data to and from the CPU. The higher the clock speed, the faster the RAM can transfer data. A clock speed of 667MHz is relatively fast and is suitable for high-performance computing applications.
PC2-5300
PC2-5300 is a type of DDR2 SDRAM memory that has a memory clock speed of 667MHz. The PC2-5300 designation refers to the peak bandwidth of the memory module, which is 5.3GB/s. The peak bandwidth is the maximum amount of data that the RAM can transfer in one second.
In summary, the 408854R-B21 HP RAM is a high-performance DDR2 SDRAM module that is designed to provide fast and reliable performance in demanding computing environments. With its ECC registered memory technology, 240-pin connector, and 667MHz speed, it is an ideal choice for servers, workstations, and other high-performance computing systems.Main Information about the HP 408854R-B21
