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.

I need 1.30v to run at 5Ghz on all cores with -1 AVX offset.

Just yesterday I tried to run 5Ghz with same voltage without AVX offset and after 40 mins of XTU stress test Whea Logger 19 Cache Hierarchy Error started to pop up. Changing voltage to 1.330 solved problem.

Keep in mind BF 5 or AC Odyssey are using AVX instructions so that may require to add some voltage in some cases.

Increase vcore or raise loadline calibration by one level.

I am on stock actually i am on 4700mhz and i will test much more. But my question is.
Whea Logger 19 Internal Parity Error related to insufficent Vcore ? Cache hierarchy the same?

check the Windows log events for whea error. share the screenshots here.

Add the game related files like.exe , .dll into exclusion list of antivirus software and allow the game in firewall
