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.
With the enhanced machine check
architecture (eMCA) feature, the BIOS
collects error information from hardware
registers in compliance with UEFI
specifications, sends the error information
to the OS over the APEI of the Advanced
Configuration and Power Interface (ACPI),
and locates the error unit, improving system
availability.
