9900K 5GB OC - overclock question

[sewerino26]

Hello. I am getting WHEA logger 19 , when running RealBench and sometimes on idle.
Cpu is 9900K oced to 5ghz in uefi . I used 5G Oc profile.
2x16 GB DDR4 3000MHZ GSKILL.


Cpu Core/ Cache Voltage in Uefi is 0.932v ( auto )
CPU VCCIO Voltage is 1.312 ( auto )

What voltage should i change?
