8GB PC2-5300 DDR2-667 ECC Network Server Memory RAM

Frequently Asked Questions about the 8GB PC2-5300 DDR2-667 ECC Network Server Memory

The PC2-5300 DDR2-667 EEC network server memory is a type of memory module that connects directly to the circuit board in your server. It uses a type of technology known as \"DDR2,\" which has a total of four data transfers per internal clock cycle. These specific modules have 8GB of memory, and are available on eBay.

Large server farms or data centers typically require a large amount of memory to properly process all the client data. As the capabilities of the server scale up, you may need to add more memory. These modules are designed for servers in the sense that they come with specific features that may enhance the efficiency and performance of the memory in your server.

The DDR2 technology within these modules also offers distinct advantages. A PC2-5300 module has a base clock speed of 166.67 MHz, but because of DDR2 technology, the actual data transfer rate is four times that amount or 666.67 million transfers per second. Because the module transfers data on a bus thats 8-bytes wide, the peak bandwidth is actually eight times the transfer rate, which is 5,333.33 megabytes per second. Depending on conditions, real-world performance may be somewhat lower.

The exact specifications may vary slightly, but most of these affordable modules on eBay should come with the following features:

• Error-Correcting Code: Error-correcting code, or ECC for short, can detect and correct most types of errors in the memory. The error-correcting process takes up more resources, but it is also important for scientific or technical tasks that cannot tolerate even small errors.
• Buffered Memory: As memory density increases, the quality of the signal starts to degrade at the bus interface. Buffered or fully buffered memory improves the reliability of the signal at the cost of slightly increased latency. This is beneficial for systems or servers that have a lot of memory.

Most modules will likely use a standard DIMM or a buffered DIMM connection. The buffered memory mentioned previously is only compatible with certain motherboards due to the differences in notches on the module itself, so make sure you are choosing the right memory.

Another important factor is the compatibility between different types of memory modules. DDR2 memory is only compatible with other DDR2 modules. It is not compatible with DDR1, DDR3, or DDR4, so do not mix them together. You can mix different models of DDR2 memory together, but the server may also only operate at the speed of the slowest module. Since a typical server will contain several modules stacked together, this is an important factor. You should also make sure that the motherboard is compatible with DDR2 memory as well.
