Buffered memory is an older term for registered memory (It's actually different and registered RAM won't fit in a standard slot, buffered refers to an electronic buffer placed between the memory and the memory controller).
However, some new large systems use "fully buffered memory". In normal registered/buffered memory, only the control lines are buffered whereas in fully buffered memory, the data lines are buffered as well. This is a type of memory designed purposely to control the amount of electric current to and from the memory chips at a time. Fully Buffered Memory is not compatible with registered/buffered memory, and motherboards that require fully buffered memory usually will not accept any other kind of memory.

“Always get rid of theory private object in this way: assume that it constantly changes, but that you do not notice the change because your memory constantly deceives you.”
