AMD Threadripper / TR4 mainboards do not support registered memory. While some Intel X299 mainboards initially supported registered memory with Core i9, this was disabled by BIOS / microcode updates. |

'''Registered Buffered Memory (R-DIMM)''' Buffered memory is an older term for registered memory. Buffered refers to an electronic buffer placed between the memory and the memory controller. In general registered RAM
'''[[Fully Buffered DIMM]] (FB-DIMM)''' modules are used in some systems with large maximum memory capacities. In normal registered/buffered memory only the control lines are buffered, whereas in fully buffered memory the data lines are buffered as well with all transfers performed in a serial fashion; the additional logic present on each FB-DIMM module transforms serial input into parallel signals required to drive memory chips.<ref name="lrdimm">{{cite web
