Abstract: An information handling system includes a processor that runs a maximum memory stress test of a memory module with a refresh rate of memory devices set to a first refresh rate. Then, the processor may receive a power consumption of the memory module. Also, the processor may receive the temperature of the memory devices, and may set the refresh rate to a second refresh rate. The processor may continuously receive both the power consumption of the memory module and the temperature of the memory devices. Based on the continuously received temperature, the processor may determine whether the temperature of the memory devices exceeds a second threshold temperature. If so, the processor may store a first setting as a refresh setting for the memory module. Otherwise, the processor may store a second setting as the refresh setting for the memory module.

Abstract: An information handling system includes first and second memory modules, and a central processing unit. The first memory module includes one or more memory ranks of memory devices, and a first plurality of thermal sensors. The second memory module includes one or more memory ranks of memory devices, and a second plurality of thermal sensors. The central processing unit receives first thermal telemetry data for the first memory module from the first thermal sensors, and second thermal telemetry data for the second memory module from the second thermal sensors. In response to the reception of the first thermal telemetry data, the central processing unit determines a first localized temperature of a first memory rank. In response to the first localized temperature exceeding a threshold temperature, the central processing unit re-maps access of data from the first memory rank to a second memory rank.

Abstract: A memory device failure recovery system includes a memory device management engine that is coupled to a first memory device via a first memory device slot, and a memory device management database. The memory device management engine identifies that the first memory device has experienced a failure in a configuration region of the first memory device during a current boot operation and, in response, retrieves memory device component information and memory device configuration information that is stored in the memory device management database and that was retrieved as part of a prior boot operation from a memory device that was connected to the first memory device slot. During the current boot operation, the memory device management engine determines whether first memory device components on the first memory device correspond to the memory device component information and, if so, uses the memory device configuration information to configure the first memory device.
