Abstract

Disclosed is a method to isolate uncorrectable memory errors at the time of failure in systems protected by Error Correction Code (ECC). Because memory error can be hard to recreate due to the many modes of failure, are hare to isolate, the best time to identify the failing Dual Inline Memory Module (DIMM) is at the time of failure. On systems with the data bus covers more then one DIMM, With out better isolation all DIMMs in the chip select group would need to be replaced.
