unbuffered DIMM

See RDIMM.



RDIMM

(Registered DIMM) A dual in-line memory module (DIMM) with improved reliability. The RDIMM, which became available for DDR3 memory, uses a hardware register that buffers the control signals (not the application data) to the modules. The buffering adds a clock cycle and uses more power but handles the heavier electrical loads placed on high-speed, high-density memory modules better than the traditional DIMM, or "unbuffered DIMM" (UDIMM). RDIMMs also support Chipkill/SDDC memory (see chipkill). When two or more DIMMs are used per memory channel, RDIMMs typically provide greater performance than UDIMMs, but the motherboard documentation must be consulted to determine which modules can be used. See memory module and SDRAM.
