Hi there . For a while ill have to be gaming on a gigabyte gtx 750Ti 2gb video card , and of course i want to overclock it since i got windforce edition which is very cool . arround 50-55C at full load. My problem is that when i use some program (precisionX , MSI Ab , oc guru ) and when i set clocks and voltage , it applies clocks but not voltage . It sticks at its factory one. Program applies setting , but gpu wont work on it. Am i stuck with locked gpu or there is some way i can unlock that voltage ? Since its very cool gpu and its like throwing its power in the wind with 50C and stock voltage...Thanks all for taking time to read this :)

If you can't set the voltage in the GIGABYTE software this is a voltage locked model.

This gpu has a really bad bios then , because its minimum fans speed is 40 % , and that voltage lock , i can set the offset min and get it up , but offset max voltage wont work. Is there any way i can disable its overclock, and set it to be a stock gtx 750ti ? I feel so bad leaving it like this :(

you can not change voltage on locked gpu's.

The absolute best you can hope for is using a different bios, but thats risky in itself.

You should still be able to adjust fan profiles in msi afterburner though, should be no issue with that.
