You would need to check the voltage point's on the card. And that will show you that the voltage is going up or down.
 
Edit:
Test one shows voltage at 1.3, but in reality it's 1.23V
 
Test two shows voltage at 1.3, but in reality it's 1.29V

I tried to modify my stock bios with Maxwell II Bios tweaker by making max voltage 1.28 and raising the TDP of the card, and it did nothing, didnt change a thing when I flashed the modify back on. Is there any way I could get help from one of you guys in modifying my bios as you guys seem to know what you are doing? Ty in advance.
 
This is my stock bios http://www.filedropper.com/gm200

Try this one.... https://www.mediafire.com/?vvfutd8t2asvilw

I tried the bios you sent but the card is still reporting 1.2120v at max load on Heaven.

I'm assuming your build is right in your sig?  If so.....the card will never read over 1.212v.  You have a Classy.....in order to change voltage, you'll need to use the Classy voltage tool.  Search "980ti Classified Voltage Tool Kingpin Forums".  You'll find it.

You'll also find, that running between 1.17 and 1.187 will serve you a lot better with the Classy, than trying to run anything more than that.  

Just using the Classified tool alone I couldnt get above 1.212v, or did you mean to use the classified tool with the modded bios?

If you're using GPUz, it's not going to read the correct voltage...it's going to show 1.212v.  Regardless....you're not going to get anywhere with extra voltage, unless you have some pretty extreme cooling.  Like, at a minimum, below 30c under load.  Your best bet to get higher clocks, is to keep the temps down.  1.187v to 1.193v for air / water cooling.  Going above 55c on the core, will give you almost 0 chance of reaching above 1500.

Mine reads 1.3V

I've never seen anything but 1.2 or 1.212.  No matter what I set the voltage tool to.  Regardless...setting that much voltage with the Classy tool isn't going to do anything without pretty amazing cooling.

That's because in our case.... The vbios and the voltage/power have to actually jive together. So using the classy tool without moving the voltage in the bios will cause many issues. Unless you hardmod the voltage and power. 
If you looked at the pictures i posted you will see that the voltage is in fact @ 1.3 on gpuz, but in reality it's 1.23V in picture 1. And 1.29V in picture 2, but if you just use the classy tool without moving the voltage "numbers" higher in the vbios something weird start's happening.
 
Still testing that stuff, but haven't had a lot of time.
 

But changing the voltage above 1.212 in the bios doesn't do anything....it may be reading it from the bios, but....it's not going to run at that voltage.

You could very well be right.... And it's not actually just the voltage you change but the slider voltage as well. Although evga precision won't work once you do this though....

I can tell you with a pretty great amount of certainty, that actually running that much voltage through a Classy without sub-ambient cooling wouldn't yield anything but higher temps, which in turn would result in lower overclocks.

That was a given? I thought that was pretty much well known? If you don't have the cooling then one should not be trying to go higher. With power or voltage beyond ones means.

And that's what I was trying to relay to the other poster, until you stepped in talking about 1.275v and 1.3v......just sayin.
