Cache Hierarchy error.

[sewerino26]

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?

Simple answer, if you reformatted, installed same drivers and the same windows updates and now its NOT doing it then it cant be a hardware issue.

I formatted disk again to reproduce issue but no luck, issue not repeated. Using the same Windows 10 not updated,the same drivers and this time no WHEA-LOGGER 19. Any clues why it happened on 21 january only?


UEFI BIOS the same settings

4700 is not normal for 8700k. are you sure you don't have MCE on?

 

[sewerino26]

yes MCE is on. But all working fine with this clock . This warnings was only in 21 january. After 21.01 till today no warnings.

But i wonder why they happened on this day.
