VID voltage increases and vcore voltage drops under some load, normal?

My 7700k Vcore goes from 1.152v to 1.136v and VID increases from 1.155 to 1.180 whenever there is a load like opening chrome or playing a game that uses like 40% + of my cpu.

These voltage hoppings are always the same numbers, if I set my voltage higher it still increases and drops by the same amounts. Is this supposed to happen/safe?

This is basically my "problem", any help would be appreciated.

And the same happens when I set my voltage to its defaults:

(Under prime95, the voltages remain stable and never go up or down)


Also, I have no clue why I have an iGPU voltage there, I don't use integrated graphics, any ideas?

Yeah that's normal the VID voltage for my 7700k does the same thing at stock settings. VCORE voltage will always drop when the CPU goes under load this is called VDROOP. It is perfectly fine assuming the CPU is stable, you can combat this with a setting called LLC (Load line calibration) in the bios. When you have a high level of LLC set VCORE will stay closer to the VCORE voltage set in the BIOS. However I doubt your H110 mobo has an option for LLC, an H110 mobo and a 7700k is an odd combo.

the 7700k was a gift since I needed a good single core cpu hence I didn't buy a proper motherboard for it, it works fine with 4.5 ghz which is all I need and ran stable on prime95 for 2-3 hours(Undervolted to 1.15v with intel XTU since the motherboard doesn't let me adjust voltages)

So VID going up and vcore going down under load is normal? Thanks!

Yup it's normal. That's exactly the way my 7700k acts a stock settings, with slightly different numbers.

Replying to your PM on here because I can post a picture. It doesn't look like my motherboard even shows iGPU voltage. It is probably perfectly normal assuming your dedicated GPU is being properly utilized. I will look it up and see what I can find.
