[MKang3]

Hi Sir,

I got a Windows WHEA event, is that an error from the CPU?

Windows 10 decodes it as follows:

Component: Processor

Source: Machine Check Exception

Type: Internal parity error

Processor APIC ID: 6

If you need some more data, ex: SSU, DIMM test result...etc, please check: https://community.intel.com/t5/Processors/Windows-WHEA-crash-Xeon-R-W-11955M/m-p/1398775/emcs_t/S2h8ZW1haWx8dG9waWNfc3Vic2NyaXB0aW9ufEw1Qk9KWjMxWDVVOUoxfDEzOTg3NzV8U1VCU0NSSVBUSU9OU3xoSw
