An information handling system includes interleaved dual in-line memory modules (DIMMs) that are partitioned into logical partitions, wherein each logical partition is associated with a namespace. A DIMM controller sets a custom DIMM-level namespace-based threshold to detect a DIMM error and to identify one of the logical partitions of the DIMM error using the namespace associated with the logical partition. The detected DIMM error is repaired if it exceeds an error correcting code (ECC) threshold.
