Multi-bit errors are detected at the bank level rather than the DIMM level, so if a multi-bit error occurs, both DIMMs in the bank must be replaced. As long as no errors have occurred on the memory board, the system periodically switches which set of banks it reads from to be sure that both sets are monitored for memory errors.
