System and method to control memory failure handling on double-data rate dual in-line memory modules

A method of controlling memory failure handling, the method comprising:

• providing, by a memory controller of an information handling system, interrupts to a processor of the information handling system each time a read transaction between the memory controller and a dual in-line memory module (DIMM) of the information handling system results in a correctable read error;
• receiving, by a failure predictor instantiated by the processor, the interrupts;
• accumulating, by the failure predictor, a count of the interrupts;
• and
• providing, by the failure predictor, a first error indication when the count exceeds a first error threshold;
• wherein the accumulating further includes:
• incrementing the count each time the predictor receives a particular interrupt;
• and
• decrementing the count in accordance with an error leak rate, wherein the error leak rate has a first value when the DIMM is newer than a first age threshold and has a second value when the DIMM is older than the first age threshold.

An information handling system, comprising:

• a processor;
• a hardware management engine;
• a dual in-line memory module (DIMM);
• and
• a memory controller coupled to the DIMM, the memory controller including a count of a number of times a read transaction from the DIMM resulted in a correctable read error;
• wherein the hardware management engine is configured to instantiate a failure predictor to retrieve a first number of correctable read errors from the memory controller, to determine a difference between the first number of correctable read errors and a second number of correctable read errors retrieved by the failure predictor, to adjust the difference in accordance with an error leak rate, and to provide an interrupt to the processor when the adjusted difference exceeds an error threshold, wherein the error leak rate has a first value when the DIMM is newer than a first age threshold and has a second value when the DIMM is older than the first age threshold.
