What to look for in a server RAM/Memory

There are several types of server RAM, including:

1. DDR4 (Double Data Rate 4) – The latest and fastest type of RAM for servers, operates at higher speeds and with more bandwidth compared to DDR3.
2. DDR3 (Double Data Rate 3) – A previous generation of RAM that is still used in some servers, operates at slower speeds compared to DDR4 but with similar bandwidth.

The following specifications are important for users to understand:

1. Speed (in MHz) – Determines the rate at which data can be transferred between the RAM and the CPU. A higher speed means faster data transfer.
2. Latency (in CL) – Refers to the delay between the time a command is sent to the RAM and the time it takes to execute the command. A lower latency means faster response times.
3. Capacity (in GB) – Specifies the amount of memory available on each RAM module. The more memory a server has, the more applications it can run simultaneously.
4. ECC (Error Correction Code) – Refers to the capability of the RAM to detect and correct errors in data. This is important in server applications where data integrity is critical.
5. Registered/Unbuffered – Refers to the type of electrical signalling used to control the flow of data between the RAM and the CPU. Unbuffered RAM is typically used in desktop computers, while registered RAM is used in servers.
6. Voltage – Specifies the voltage required to operate the RAM. Some RAM types require higher voltage to operate, while others are designed to run at lower voltage levels.

With your service tag or server serial, we can help you pick modules that are compatible with your existing RAM to ensure the most viable and smooth upgrade.
