9900K WHEA LOGGER Internal parity error or cache hierarch error.

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


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.


1.320v - Whea 19 Internal Parity Error (1 in 3-4 months ) in Metro Exodus
1.320v - Whea 19 Cache Hierarchy Error in Realbench

1.330v - Whea 19 Internal Parity Error ( 1 in 3 months ) in Battlefield 5
1.330v - no Wheas in Realbench



I am actually 9900K on stock 4700ghz,all auto in UEFI.

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