Feature Description
CPU Corrected machine
check interrupt
(CMCI)
Corrects error-triggered interrupts.
DIM
M
Failed DIMM
Isolation
Identies a faulty dual in-line memory module
(DIMM), and isolates it from others before
replacing the DIMM.
Memory Thermal
Throttling
Automatically adjusts DIMM temperatures to
avoid damage due to overheating.
Rank Sparing Allocates memory ranks as backup ranks to
prevent the system from crashing due to
uncorrectable errors.
Memory Address
Parity Protection
Detects memory command and address errors.
Memory Demand and
Patrol Scrubbing
Provides the memory patrol function for
promptly correcting correctable errors upon
detection. If these errors are not corrected
promptly, uncorrectable errors may occur.
Memory Mirroring Improves system reliability.
Single device data
correction (SDDC)
Provides a single-device, multi-bit error
correction capability to improve memory
reliability.
Device Tagging Degrades and recties DIMM device faults to
improve DIMM availability.
Data Scrambling 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.
PCIe PCIe Advanced Error
Reporting
Improves server serviceability.
QPI Intel QPI Link Level
Retry
Provides a retry mechanism upon encountering
errors to improve QPI reliability.
Intel QPI Protocol
Protection via CRC
Provides cyclic redundancy check (CRC)
protection for QPI packets to improve system
reliability.
OS Core disable for fault
resilient boot (FRB)
Isolates a faulty CPU during startup to improve
system reliability and availability.
