==Compatibility==
Usually, the [[motherboard]] must match the memory type; as a result, registered memory will not work in a motherboard not designed for it, and vice versa. Some PC motherboards accept or require registered memory, but registered and unregistered memory modules cannot be mixed.<ref>{{cite web|url=http://www.dell.com/downloads/global/products/pedge/en/server-pedge-installing-upgrading-memory-11g.pdf|title=Dell servers example|last=|first=|date=|website=Dell|publisher=|archive-url=|archive-date=|dead-url=|access-date=}}</ref> There is much confusion between ''registered'' and ''ECC'' memory; it is widely thought that ECC memory (which may or may not be registered) will not work at all in a motherboard without ECC support, not even without providing the ECC functionality, although the compatibility issues actually arise when trying to use ''registered'' memory (which also supports ECC and is described as ECC RAM) in a PC motherboard that does not support it. AMD Threadripper (LGA4094), and Intel Core i9X (LGA 2066) motherboards meant for the HEDT (High End DeskTop) market, are unique in a way that they both support regular normal DDR4 DIMMs operating at a max speed at 4666MHz+ up to 16GB/module), and FB, UB, R, and LR DIMMs (up to 128GB/module). {{Citation needed}}
