i7 4770k 1.2V stock voltage

hi guys, got my pc now but i ran into some problems. when i'm at idle i got 0.7V and under load it should be 1.059V. but i;m now downloading my steam games and i'm on 1.2V and aida64 runs between 1.15V and 1.3V. is that oke?

update: aida64 20min blue screen on 1.06V. i changed the Vcore to 1.059 instead of auto, but it's now 1.06 all the time.

why i'm still unstable?
