Description
Corrects error-triggered interrupts.
Identifies a faulty DIMM and isolates it from others
before it is replaced.
Automatically adjusts DIMM temperatures to avoid
damage due to overheating.
Allocates some memory ranks as backup ranks to
prevent the system from crashing due to uncorrectable
errors.
Detects memory command and address errors.
Corrects errors upon detection. If these errors are not
corrected promptly, uncorrectable errors may occur.
Improves system reliability.
Provides a single-device multi-bit error correction
capability to improve memory reliability.
Degrades and rectifies DIMM device faults to improve
DIMM availability.
Optimizes data stream distribution and reduces the
error possibility to improve the reliability of data
streams in the memory and the capability to detect
address errors.
Improves server serviceability.
