Issue resolved. Processor issue.
I guess my processor has burned in over the months of 24/7 usage. And i got it 2nd hand, not sure how the previous user might abuse it.
I been trying all sorts of methods and settings in BIOS. until i limited the multiplier to x30. which means my 5900x will only hit 3.0Ghz max.
And so far its been stable.

its been 20 hours. so far seem stable. *fingers cross*
lets hope its really the C states.
 
but regarding the mcelog. how do i verify? cuz it says this processor is not supported.
 
Update: Ah forget it. i realized i can't pipe the logs to the shares as the array is offline during bootup and shutdown process.
and mcelog probably gets reset during a reboot. so i will just pray that my system is stable now.
