my system is manually overclocked like all the other ones i had before.
i use a moderate LLC to compensate the transient dips and spikes instead of pushing 0 mOhm.
The CPU has a fixed voltage, like the ram,VCCIO/SA and Chipset.
No Vcore does not scale with it.
it is ONLY the Systemagent and ONLY since yesterday. it NEVER was a problem (since i monitor voltages and temperatures almost non stop.)
i went back to 4.20 now (4.30 is the new one released in "early 2020" so a few days ago.)
