afterburner: can't flatten curve under 900mv

[kenmastaz159a02e0]

Hi,
Im trying to undervolt my pny 5090 with afterburner but I have a strange problem.
When setting a point at 850mv-2850mhz and trying to flatten the rest of the points after pressing apply
the curve changes and creates a fade in from 850mv to 900mv and then flattens.

No matter what I choose it always creates a fade in to 900mv and then flattens.
Im on the newest Nvidia driver 576.15 and afterburner 4.6.6 beta. the final version doesn't work.

How can I fix that ?

Thanks!

It could be a hardware limitation 850-mv is very low for higher clock speeds.

hi,

this is the guide I tried to copy/paste and they are able to oc with less than 900mv but not me. When reseting the curve or starting new my curve looks different than every other guide.....
