An apparatus and method for error logging on a memory module, such as a DIMM, are provided. If an error occurs in a memory module, the operating system of the computing device stores a log of the error in a storage device mounted to the memory module. The log may identify the type and quantity of errors caused by the faulty memory module and may also include defective bit identification information. The defective bit identification information may be used to identify individual memory elements on the memory module that are defective. If the errors exceed a given quality or quantity level, the operating system may store an indicator in the storage device on the memory module that the memory module is defective and take that memory module off-line to prevent problems from occurring with the programs that are running on the computing system.
