I'm warnings about Hardware Check Events from Fix Common Problems plugin - mcelog is installed, details of the reported errors are below. What is going wrong?

Diagnostics file is attached.

If I would guess (sans diagnostics), disable all overclocking, including XMP 

Thanks, I'll do that and see if it goes away. Also, I now read up more (sorry!) and I can attach diagnostics next time.
