I had been noticing that my 3900x will use 1.5v at normal operation or auto overclocking. To prevent degradation I decided to under volt to 1.3v. After that I noticed that the processors would not boost past 4.0Ghz even at 1.5v, so I decided to manually tune the cores to 4.3Ghz.
However I notice that the processor will not step down the frequency when it hits the thermal limit of 95C. It will go past 100c with no thermal throttling.
I even went into PBO to manually set a thermal limit of 95C but this did not work either.
How can I fix this?
