9900K oc question and WHEA LOGGER Internal parity error or cache hierarch error.

[lpiotrowski211]

Hi my pc:
9900K OC sync all cores was 50 now i have 47
2x16GB DDR4 GSKILL 3000MHZ
Corsair 850RmX
Asus Prime Z390-A

Few questions.
On 5ghz with voltage 1.320v i had very rarely Whea Logger 19 Internal Parity error during game in Metro Exodus.
So rarely like 1 pop up Whea in 1 month.
Also on Realbench on 1.320v i had Whea Logger 19 Cache Hierarchy Error.
So i bumped to 1.330v and 2 months was fine. But yesterday in Battlefield 5 Whea Logger 19 Internal Parity error pop up in Battlefield 5 on 1.330V.

And my question. Is Whea Logger 19 Internal Parity Error related to insufficent Vcore ? Cache hierarchy the same?

Last question.
Now i have cpu in 4700mhz. But this is underclock right? Because all cores running on 4700mhz. On stock cores running on 4700mhz but 2 cores on 5000mhz.

Please share opinions.

Increase vcore or raise loadline calibration by one level.

Whea Logger 19 Internal Parity Error related to insufficent Vcore ? Cache hierarchy the same?
