Description
Corrects error-triggered interruption.
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.
Provides a retry mechanism upon
errors to improve UPI reliability.
Provides cyclic redundancy check
(CRC) protection for UPI packets to
improve system reliability.
Isolates a faulty CPU core during
startup to improve system reliability
and availability.
