First off all, you are doing everything on your own risk.
You can brick mainboard if you push GPU beyond limits.

There are three files:

1. This readme file which you MUST READ CAREFULLY and UNDERSTAND!

2. ORIGINAL.reg - This file will return default values if something goes wrong

3. P7 1077 autoV.reg - This file will modify Soft Powerplay Table in windows registry which is "shadow" of GPU BIOS table.
It will mod P3 to 1073MHz / auto voltage
It will add P4 as 1074MHz / auto voltage
It will add P5 as 1075MHz / auto voltage
It will add P6 as 1076MHz / auto voltage
It will add P7 as 1077MHz / auto voltage

Auto voltage means driver(?)/GPU(?)/OS(?) will determine core voltage automatically based on ASIC quality and "who cares" what else ;).
Unfortunatelly GL702ZC GPU do not have offset value set in vBIOS. And it's a little bit wierd how it uses core volatge states.

In my case 1077MHz will be at 900mV which is 100mV lower then stock GL702ZC gpu core voltage that you can read with MSI AB or other program. 
But it's the same 900mV which is determine automatically on original settings.
So why GPU isn't using default BIOS value 900mV?
It is beacuse VRAM uses 1000mV on default. If you lower VRAM voltage to 900mV it will use 900mV on core like in default settings.
So basically VRAM voltage is limiting bottom core voltage. This is important detail.

All above about core voltage is true only if core voltage in MSI AB is set to 0mV.
This slider works fine even on stock settings. It will work on modded soft powerplay table as well.
But...
GPU can be very unstable when you will use it to undervolt after core OC on more than one P state.
After first try with slider set to -31mV and crash while using AMD Chill set to 41FPS, i did not test with slider set to other value than 0mV any more.
It looks like slider will affect all P states. When they are changing a lot (like with AMD Chill) it can cause a lot of problems.

If you want to OC: for your own wallet set FAN BOOST in ROG Gaming Center to >+20%

So if you read this file and still want to try fry your GL702ZC then go ahead, click "P7 1077 autoV.reg" twice and have fun!
