Description
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.
Identifies the memory storage unit that contains
corrupted data to minimize the impact on running
programs and improve system reliability.
Isolates a faulty socket during startup to improve
system reliability.
With the eMCA feature, the basic input/output system
(BIOS) collects error information recorded in 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.
Injects errors to verify various RAS features.
