Hi,
I got a BSOD due to a Machine Check Exception. The CPU is an i7 4790S.

This 2nd section is most likely the culprit. I have looked for IA32_MCi_STATUS[31:16] = 0080 to figure out what kind of Internal Timer Error occurs, but for this 06_3Ch Family/Model I could not find a Model Specific Error Code.
Can you tell me if there are other models that are compatible with this Haswell Microarchitecture?
The MCA_SECTION contains the following values:
