ECC refers to Error-correcting Code, a dynamic, comprehensive algorithm-formulated method of data integrity checking that corrects single-bit errors and detects multiple-bit errors automatically during transmission. ECC DIMM is designed for high-end personal computers, servers and workstations that are relatively mission-critical and in compute-intensive environments, providing more precise and reliable data-processing capability.
R-DIMM stands for Registered Dual In-line Memory Module. R-DIMM incorporates a register - a logic component - placed directly on the memory module to set aside a quantity of command/address bus for quicker access, therefore reducing the load on the system’s memory controller and improving signal integrity. R-DIMM thus utilizes the system’s higher memory capacities and bandwidth, meeting the demands that servers and workstations require in terms of scalability and stability.
