Description
Corrects error-triggered interrupts.
Identifies a faulty dual in-line memory module
(DIMM), and isolates it from others before
replacing the DIMM.
Automatically adjusts DIMM temperatures to
avoid damage due to overheating.
Allocates memory ranks as backup ranks to
prevent the system from crashing due to
uncorrectable errors.
Detects memory command and address errors.
Provides the memory patrol function for
promptly correcting correctable 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.
Provides a retry mechanism upon encountering
errors to improve QPI reliability.
Provides cyclic redundancy check (CRC)
protection for QPI packets to improve system
reliability.
Isolates a faulty CPU during startup to improve
system reliability and availability.
