Checked it on hwinfo64... you were right. it says 1.131v. So, how do i lower that on bios? There should be something i did completely wrong...
The undervolt you actually made is just the floor voltage for core.
Actual core voltage hovers between voltage values indicated on p7 core and p2/p3 mem. Use overdriventool disable all states except p7 and p2/p3 mem (highest) and set the voltage 925mV in p7 and 900mV in p2/p3 mem. Check actual voltages while mining you should be hovering in between these two values.
If you undervolt too much you might just crash or drivers won't honor it
