WHEA Logger entries 8700K


Hello. I was checking event logs on 25.10.2018 and had spam of WHEA-LOGGER 19 entries.
They happened when system was idling from 23.10 - 25.10 , so nothing happening in system only spam. Is this reason to worry? My actually Windows 10 is 1803.

Ah and i remember i had them too on 21.01 january but they dissapeared after 21.01 january.
Windows 10 1709 build 16299.15 it was.

Like i said.
But now they appeared again after few months ,from 23.10 october -25.10 october and dissapeared again.
Windows 10 1803 actually.

A spam of:
WHEA Event ID 19 CPU-corrected hw error

A corrected hardware error has occurred.

Reported by component: Processor Core
Error Source: Corrected Machine Check
Error Type: Cache Hierarchy Error

Screens are from january 21.01 but this is the same of course warning whea entry:

My pc:
8700K ( MCE is on , always was on 4700mhz )
Corsair 750rmi
Asus Z370 Pro Gaming ( bios old from august 2017 )
Gtx 2080 Ti Gigabyte Windforce
1xssd , 1xHdd

Dont have any crashing,no freezing,no bsods,scores are fine etc.

So question. ANyway is this reason to worry or skip it if they stop it again?
Maybe something with voltage or something ( reading reddit ) but they appeared when system was idling ( not gaming ) and i was away from pc. All drivers installed.


WHEA errors are almost always from not quite enough CPU voltage - are you either overclocking or forcing all core turbo all the time?
