Cache Hierarchy error.

I have a 8700K (default bios settings) for a month now. I have only just noticed after scrolling through event manger that i have been getting these warnings only from 21.01 january:
A corrected hardware error has occurred.

Reported by component: Processor Core
Error Source: Corrected Machine Check
Error Type: Cache Hierarchy Error
Processor APIC ID: 0 (also sometimes happens for 6 or 8 aswell)

I havent seen any affects that might be caused from this like BSODS or freezing. All stable. Intel diagnostic tool passing. Memtest86 no errors. IHC memtest no errors. Either way should i be concerned of that errors from 21.01?

my pc: 8700K ( 4700MHZ is on auto by motherboard )
2x8GB DDR4 GSKILL 3000MHZ XMP ON
Corsair 750i
SSD Crucial 525GB MX300
HDD TOSHIBA 500GB
Asus Z370 Pro Gaming bios 215
Windows 10 Fall Creators Update 1709

I tried to reproduce issue by formatting disk and installing again Windows 10 but they dont appear again. From microsoft they said that this is hardware issue. So why i cant reproduce this?

As you have reformatted the disk and done a fresh installation it is not possible to review the old errors. If they are not happening again I would not worry about it. It was most likely due to some drivers carried over from previous versions and the fresh installation has sorted it.

If you spot them again we can do some more investigation at that time.

Look that that next whea was appearing exactly on the same second and next minute.
