Abstract
An information handling system includes a processor and memory devices that each include a voltage regulator configured to be enabled by a command from the processor. The processor boots the information handling system, including providing the command to the memory devices, and detects that one of the memory devices failed to boot. The processor determines that it is unknown whether the failing memory device is the first memory device or the second memory device. In response, the processor determines which one of the memory devices failed to boot, by rebooting the information handling system, providing a command to a selected one of the memory devices, and determining whether or not the selected one of the memory devices failed to boot.
