What are the differences among registered, buffered, and unbuffered memory?
Registered memory is designed for motherboards that accept a large number of module slots and larger capacity modules. This type of memory is mainly used in servers that require a large amount of memory. Buffered memory is basically the same as registered memory, but the term is used for the older EDO and FPM memory types. Unbuffered memory does not contain the chip that allows for the extra features in registered and buffered memory. Unbuffered memory is cheaper and the popular choice in home computers.
