Abstract: The invention relates to a method for recording a memory parameter and a method for optimizing a memory. In the invention, adjusted enhancement parameter data can be stored in a non-volatile memory of a memory module. Then, the setting value of a parameter of a memory module is portable, and users can write the needed setting value of the memory parameter into the non-volatile memory of the memory module. In other words, in the invention, no matter whether the memory module is applied to the same computer or not, the enhancement parameter data can be applied to prevent the users from repeatedly setting the memory parameter of the memory module in different computers.

Abstract: A method and apparatus is disclosed herein for diagnosing configuration faults. In one embodiment, the method comprises: detecting a violation to one or more dynamically constructed invariants for configuration; and diagnosing a misconfiguration based on use of a task-based ranking of misconfiguration suspect causes in which suspect causes of the misconfiguration are ranked based on information indicative of which entity made a change related to the one or more invariants for which a violation was detected.
