What are the differences between unbuffered, buffered and registered memory?
Home computers should use unbuffered memory modules that do not have a register. That’s good because this type of memory is faster and less expensive. Buffered modules contain a buffer to help the chipset deal with the type of electrical load required when the system has a large amount of memory. Registered modules are unbuffered modules that contain a register that helps ensure data is handled properly. Buffered and registered modules are typically used only in mission-critical systems, such as servers.
