RDIMM

RDIMM – Registered Dual Inline Memory Module. Unlike a standard (unbuffered) DIMM the RDIMM features a a hardware register that buffers the DIMM control signals but not the application data, between the memory controller and the memory chips to help stabilize and manage the electrical load of the memory modules. This increases the DIMM’s reliability by putting less of an electrical load on a memory controller. It enables RDIMMs to support larger memory capacities than is possible with UDIMMs. RDIMMs are mostly found in workstations and servers as they provide better reliability and stability.
