I though the chip could reach 2.8 - 3.0 but not luck here

I guess my opty doesn't like volts (Tcase by core temp is 59C)
I think your PWMIC temperature is overly high. Find a fan to blow at it or enhance your internal airflow and see if that helps (by stabilizing) your OC.

Not sure what kind of CPU cooling you are currently using on your 170. If it doesn't respond to higher volts well, it then means only better cooling options will help in your case.
