r/overclocking - for those who like to push their chips a little harder

I'm having an issue with undervolting my 5080 GPU using the Gpu Tweak 3 software.

For example, when I use the VF Tuner to set 0.975 volts at 3050 MHz and save the profile, the undervolt settings automatically change. Instead of giving 0.975 volts as it should, it starts giving 1.005 volts. When I open the VF Tuner again, everything looks correct, but the voltage being applied is different.

I've uninstalled and reinstalled the software and tried it 2–3 times, but it didn't help. I'd really appreciate it if anyone who knows a solution or has any ideas could share. Thanks a lot.
