MULTIPROCESSOR_CONFIGURATION_NOT_SUPPORTED

The MULTIPROCESSOR_CONFIGURATION_NOT_SUPPORTED bug check has a value of 0x0000003E. This indicates that the system has multiple processors, but they are asymmetric in relation to one another.

MULTIPROCESSOR_CONFIGURATION_NOT_SUPPORTED Parameters

None

Cause

In order to be symmetric, all processors must be of the same type and level. This system contains processors of different types (for example, a Pentium processor and an 80486 processor).

Confirm processor family, model, stepping, feature set, and firmware configuration across all CPUs; asymmetrical processor capabilities are the relevant mismatch.
