According to MSI QVL List for Pinnacle Processors (2xxx) there is no RAM compatible at 3600Mhz: https://www.msi.com/Motherboard/support/X470-GAMING-PLUS-MAX#support-mem-14
The fastest RAM Speed is 3466Mhz which probably explains why it has issues when Overclocked at 3600Mhz.
Of course the list could be Out-dated.
So it is possible that results could be because your RAM may not be 100% compatible with CPU and Motherboard.
But if your computer is working normally without any BSODs or crashes than I doubt you have a bad processor.
If you want you can open an Online AMD Service Request (Official AMD SUPPORT) and ask them if they believe AIDA64 test results indicates a bad CPU from here: https://www.amd.com/en/support/contact-email-form
