Hi,
Please accept my sincere apologies for any spelling errors—I’m French and my English is still developing, except for perfection.
😀
Regarding the issue, I’m attempting to undervolt my I7 7700k to achieve better cooling. However, changing the V-core in the BIOS doesn’t seem to resolve the problem. After updating the V-core, I revert back to Windows and check the CPU voltage using CPU-Z; it appears inconsistent since the values shown in CPU-Z don’t match those in HWmonitor, which is set in the BIOS.
Thank you in advance for your assistance!

It might be a bios issue, or possibly an internal overvoltage problem with newer boards—worth investigating.

Could you clarify which specific location you're thinking of?

Could you share a picture of your bios voltage settings?

The jumper is indeed on, correct? (edit: is there "internal PLL overvoltage")
You can also reduce the thermals by tweaking the power phase control, also known as VRMs.

There is a jumper on the board but it’s only to get voltage over safe limit, it’s from what i read only for extreme overclocking.
