Abstract: An information handling system includes a dual in-line memory module (DIMM) coupled to a memory controller via a memory channel. A processor during a first in time boot process of the information handling system determines a first environmental condition of the information handling system, and initializes the memory controller and the DIMM to determine a first set of initialization parameters for the memory controller and the DIMM. During a second in time boot process of the information handling system, the processor determines if a second environmental condition is different than the first environmental condition, if the second environmental condition is not different then to continue the second in time boot process without initializing the memory controller and the DIMM, and if the second environmental condition is different then to initialize the memory controller and the DIMM to determine a second set of initialization parameters for the memory controller and the DIMM.

Abstract: An information handling system includes a dual in-line memory module (DIMM) coupled to a memory controller. The memory controller provides interrupts to a processor each time a read transaction from the DIMM results in a correctable read error. The processor instantiates a failure predictor that receives the interrupts, accumulates a count of the interrupts, and provides an error indication when the count exceeds an error threshold. In accumulating the count, the failure predictor increments the count each time the predictor receives a particular interrupt and decrements the count in accordance with an error leak rate. The error leak rate has a first value when a training coefficient for the DIMM is greater than a deviation threshold, and has a second value when the training coefficient for the DIMM is less than the deviation threshold.
