Overclocking i5 2500k at high voltage?

I started a thread a while ago about attempting to overclock my i5 2500k, and now I’ve decided to proceed.
My CPU runs at 4.2 Ghz, but the voltages are changing between 0.9v and 1.25v, sometimes reaching up to 1.33v or 1.37v as the maximum, which seems quite high for a 4.2Ghz boost.
I adjusted the voltage settings in the BIOS under the 'Dynamic Vcore' option, but HWmonitor still shows the same readings (around 1.37v at max).
I checked guides for Gigabyte motherboards and found an option called 'CPU Vcore' on screenshots, but my BIOS only lists 'Dynamic Vcore'.
This is my first overclocking attempt, so any advice would be greatly appreciated.
My specifications are as follows:
CPU: i5 2500k 3.3ghz
RAM: G.Skill 8GB DDR3 1600Mhz RipjawsX CL9 (9-9-9-24) 1.5V
GFX: MSI NVIDIA GTX970
MOBO: Gigabyte GA-P67A-D3-B3 P67 Rev 1.0 (Version F7)
Thanks
EDIT : I added some photos of the voltage options in the BIOS menu here and there.

Adjust the vcore offset to negative values and configure it to the lowest setting you prefer. This ensures the vcore never exceeds your manually defined voltage limit and stays within the specified bounds.

Try adjusting the vcore offset to "-", then lower it as much as needed. This should keep your vcore within the voltage range you specify, preventing it from exceeding or dropping below your manual settings. Thanks for the response.
I suspect the Dynamic Core setting is related to the offset values, since those include positive and negative voltages. I changed the offset to -1.01v but the readings remain consistent in voltage. My BIOS doesn’t have a direct CPU vcore option, so manually adjusting the voltage isn’t possible here. I’ll keep testing lower offset values.
UPDATE: I switched the voltage to -0.020v and still see the same readings. Also, I observed that the Dynamic Vcore options increase in small steps (±0.010) without letting me set exact voltages.
I’ve added two links to my thread explaining the voltage settings available in BIOS.
