Description

Unable to find if there is any document that explains the reason for CATERR detected in my system.

Resolution

CATERR stands for Catastrophic Error, it is part of thermal protection signales. The CATERR# indicates that the system has experienced a catastrophic error and cannot continue to operate. The processor will set this signal for non-recoverable machine check errors or other unrecoverable internal errors. CATERR# is used for signaling the following types of errors:

  • Legacy MCERRs (Machine check errors) , CATERR# is asserted for 16 base blocks (BCLKs).
  • Legacy IERRs (internal errors) , CATERR# remains asserted until warm or cold reset.

For more information, check this documentation 13th Generation Intel® Core™ and Intel® Core™ 14th Generation Processors Datasheet, Volume 1 of 2 and check section Error and Thermal Protection Signals.
