Description
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.
Identifies the memory storage unit
that contains corrupted data to
minimize the impact on the running
programs and improve system
reliability.
Isolates a faulty socket during the
BIOS startup process to improve
system reliability.
