Feature Description
CPU Corrected Machine
Check Interrupt
Corrects error-triggered interrupts.
DIM
M
Failed DIMM Isolation Identifies a faulty DIMM and isolates it from others
before it is replaced.
Memory Thermal
Throttling
Automatically adjusts DIMM temperatures to avoid
damage due to overheating.
Rank Sparing Allocates some 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
Corrects errors upon detection. If these errors are not
corrected promptly, uncorrectable errors may occur.
Memory Mirroring Improves system reliability.
Single Device Data
Correction
Provides a single-device multi-bit error correction
capability to improve memory reliability.
Device Tagging Degrades and rectifies 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.
