Unbuffered Memory

Unbuffered memory is memory where the memory controller module drives the memory directly, instead of using a store-and-forward system like registered memory.

Some systems do not support unbuffered memory, others require unbuffered memory, and many more give you the option to use unbuffered or registered memory.

The use of unbuffered memory is reasonable for gaming systems. It is not recommended for server-class systems.

Unbuffered memory is also known as unregistered memory. Buffered memory is also known as registered memory.
