What sort of stability testing did you do to prove that your undervolt settings are stable? Does the TS Bench 960M test report any errors? That is a bare minimum stability test. I would also run some 3D Mark tests. Check the ThrottleStop Log File box when testing so you have a record of your CPU performance and temperatures.
Of the three screenshots you posted, the first two are from Oct 25th when VBS was enabled. The third screenshot from Oct 31 looks OK.
If games are crashing, your computer is not stable. Reduce the undervolt. See if you have any problems with the undervolt at -50 mV for the core and the cache. If you are still not stable then set the offset undervolt back to 0 mV.
Edit - I would set IccMax to the max, 255.75, for both the core and the cache. Post a TPL screenshot.
