Can a DIMM support both registers and buffers?

No, a DIMM (Dual In-line Memory Module) cannot support both registers and buffers simultaneously. Registered DIMMs (RDIMMs) use a register to help manage data signals, while buffered DIMMs (BDIMMs) include a buffer that can further enhance signal integrity and allow for more memory modules on a motherboard. Each type is designed for specific use cases, and their architectures are incompatible with each other.
