X64 Exception Type 0x12 Machinecheck Exception Link -

No. While the CPU raises the exception, the root cause could be memory, PCIe, power supply, or even a bad driver causing illegal bus transactions.

On x64 (and x86) architectures, exception vector 0x12 is the Machine Check Exception (MCE).
It is a hardware-initiated exception that indicates the CPU has detected an internal hardware error (e.g., cache errors, bus errors, memory errors, or uncorrectable ECC errors). x64 exception type 0x12 machinecheck exception link

Unlike typical exceptions (page faults, divide errors), MCEs are asynchronous — they don’t necessarily relate to the currently executing instruction but reflect a hardware problem detected by the processor’s Machine Check Architecture (MCA). Ask: Does the crash happen only when:
