How do i stop my gpu voltage from fluctuating so much?

[Some_Tech_Noob]

I used my power limit to undervolt my gpu since msi afterburner won't let me go into the negatives with the power slider. So i decided to use the power limit instead, surely enough it gets undervolted but the voltage keeps fluctuating. My clock speeds follow the same pattern as my voltage. I need some way stop my clocks and voltage from fluctuating, thank you.

Please don´t bump!

Which graphics card is it? Maybe the low voltage leads to problems and the card tries to power itself to not shutting down.
