Abstract
Methods, apparatus, and products are disclosed for utilizing a potentially unreliable memory module for memory mirroring in a computing system, the computing system including at least two memory modules, that includes: retrieving error information from an error log stored in non-volatile memory, the error information describing an occurrence of a correctable memory error on one of the memory modules; determining whether a memory mirroring mode is enabled for the computing system, the memory mirroring mode specifying that memory contents are mirrored on the two memory modules; and utilizing, in dependence upon the error information, the memory module on which the correctable memory error occurred to mirror the memory contents if the memory mirroring mode is enabled.
