Product Overview

In the world of computer hardware, memory is an essential component that helps the computer perform various operations. Memory modules come in different types, sizes, and speeds. In this article, we will take a closer look at the A2257233 8GB 2x4gb Pc2-5300 Cl5 Fully Buffered Ecc 667mhz DDR2 SDRAM Registered Memory Module made by Dell. We will discuss what each of these terms means and how they affect the performance of a server.

A2257233 is the product code for this specific memory module. It is a unique identifier that helps you differentiate this module from other modules that Dell produces. This code is essential when purchasing or upgrading memory modules to ensure that you get the correct type and size for your server.

8GB 2x4gb

The 8GB refers to the total capacity of the memory module. In this case, the module contains two 4GB memory chips, which are mounted on the module's circuit board. The memory chips are organized in a way that allows them to work together to provide a total capacity of 8GB. The 2x4gb notation indicates that the module contains two memory chips, each with a capacity of 4GB.


The PC2-5300 is a term used to describe the speed of the memory module. It refers to the module's maximum transfer rate, which is measured in megabytes per second (MB/s). In this case, the module has a maximum transfer rate of 5300 MB/s. This speed is relatively slow compared to modern memory modules, but it is suitable for older servers that require DDR2 memory.


The CL5 stands for CAS Latency 5. It refers to the delay between the time the memory controller requests data from the memory module and the time the data is delivered. The CAS latency is measured in clock cycles, and a lower latency indicates better performance. In this case, the latency is five clock cycles, which is relatively high compared to modern memory modules. However, it is suitable for servers that require DDR2 memory.

Fully Buffered

The term "Fully Buffered" refers to a memory module architecture that was introduced by Intel in 2004. Fully Buffered memory modules use an additional buffer chip that sits between the memory controller and the memory chips. This buffer chip reduces the electrical load on the memory controller and allows for larger memory configurations. Fully Buffered memory modules also support error correction, which helps to detect and correct data errors.


ECC stands for Error-Correcting Code. It is a type of memory that includes additional data bits that allow the memory to detect and correct single-bit errors. ECC memory is more reliable than non-ECC memory and is often used in servers and workstations that require high levels of uptime and data integrity.


The 667MHz refers to the memory module's clock speed. It indicates the number of clock cycles per second that the memory module can perform. In this case, the module can perform 667 million clock cycles per second. DDR2 SDRAM stands for Double Data Rate 2 Synchronous Dynamic Random-Access Memory. It is a type of memory that uses both the rising and falling edges of the clock signal to transfer data. This allows for a higher data transfer rate than single data rate memory.


The term "Registered" refers to a type of memory module that includes a register between the memory controller and the memory chips. This register helps to reduce the electrical load on the memory controller and allows for larger memory configurations. Registered memory modules are typically used in servers and workstations that require large amounts of memory.
