Product Overview
The 516423-B21 HP 8GB DDR3 PC3-8500 1066MHz 240 Pin CL7 ECC SDRAM Registered RAM is a type of RAM module that can be used to upgrade a computer's memory capacity. In this article, we will explore what each of these terms means and how they contribute to the overall performance of the computer.
DDR3 RAM
The first term to understand is DDR3, which stands for Double Data Rate type 3. DDR3 RAM is the third generation of DDR RAM, and it offers several improvements over its predecessors. For example, DDR3 RAM is faster and more power-efficient than DDR2 RAM, which was the previous generation.
PC3-8500
The next term to understand is PC3-8500, which is a type of DDR3 RAM. PC3-8500 refers to the RAM's peak bandwidth, which is the maximum amount of data that the RAM can transfer in a second. In this case, PC3-8500 has a peak bandwidth of 8.5 GB/s. The higher the peak bandwidth, the faster the RAM can transfer data, which can result in better system performance.
1066MHz
Another important specification to consider is the RAM's clock speed, which is measured in megahertz (MHz). The clock speed determines how many cycles the RAM can complete in a second, which in turn affects its data transfer rate. In this case, the 516423-B21 HP RAM has a clock speed of 1066MHz, which means it can complete 1.06 billion cycles per second.
240 Pin
The number of pins on a RAM module refers to the number of connectors on the bottom of the module that connect it to the motherboard. In this case, the 516423-B21 HP RAM has 240 pins. The number of pins is important because it determines the compatibility of the RAM with the motherboard. If the RAM module has a different number of pins than the motherboard, it will not fit and cannot be used.
CL7
The CL rating, or CAS latency, measures the delay between when the RAM receives a command and when it responds. A lower CL rating means a shorter delay and faster performance. In this case, the 516423-B21 HP RAM has a CL rating of 7, which means it has a relatively low latency and can respond quickly to commands.
ECC SDRAM
ECC stands for Error Correction Code, which is a type of memory that can detect and correct errors that occur during data transfer. SDRAM stands for Synchronous Dynamic Random Access Memory, which is a type of RAM that synchronizes with the system clock to access data quickly. ECC SDRAM is a type of RAM that combines these two features, making it ideal for servers and other high-performance systems that require high reliability.
Registered RAM
Registered RAM is a type of memory that uses a register to store data before it is sent to the memory controller. This allows the memory controller to access the data more efficiently, resulting in better performance. Registered RAM is typically used in servers and other high-performance systems.
In summary, the 516423-B21 HP 8GB DDR3 PC3-8500 1066MHz 240 Pin CL7 ECC SDRAM Registered RAM is a high-performance RAM module that can be used to upgrade a computer's memory capacity. It offers fast data transfer rates, low latency, and high reliability
