DYNAMIC_ADD_PROCESSOR_MISMATCH

The DYNAMIC_ADD_PROCESSOR_MISMATCH bug check has a value of 0x00000130. This bugcheck indicates that a new processor added to the system is incompatible with the current configuration.

DYNAMIC_ADD_PROCESSOR_MISMATCH Parameters

None

Diagnostic focus

Compare the newly added processor family, model, stepping, feature bits, NUMA or APIC topology, and microcode with CPUs already online. This failure is about hot-add compatibility, not processor load. Firmware or hypervisor topology changes can expose a mismatch even when the physical processors appear nominally identical.
