Package C3/C6 Memory Self-Refresh Error Handling
The following sub-bullet will be added to section 9.5.1.2 of the Intel® Xeon® Processor
E7-8800/4800/2800 Product Families Datasheet:
• Frequent transitions to package C3/C6 memory self-refresh during some idle
workloads may increase the number of recoverable (corrected) SMI link events
observed. While a low occurrence of recoverable events is normal for high speed
processor busses, the rate of recoverable events may increase during some idle
conditions due to the higher number of SMI link disable-enable transitions
occurring.
