RDIMM (ECC Registered DIMM) is a JEDEC-compliant design applicable for enterprise servers and cloud data centers. With a register between the memory module and the system’s memory controller, the RDIMM improves overall system stability and increases memory module quantity. Furthermore, it supports ECC function to detect and correct data errors to improve the memory module’s reliability.
