Undervolting a GTX 1050 on an Acer Nitro 5

[Confused2018]

Trying to help a friend with this system.  I have undervolted the cpu, it is stable, but, I am confused with the GPU. I know that the GPU in the video is a TI, so I have not followed the curve set in the video.

 

Results in Heaven are:
Graphics 1911 Mhz
Memory 3504 Mhz

Hwinfo no load
GPU core v .675 v
GPU core w .376 w
GPU clock 670.5 Mhz
GPU mem clock 405.0Mhz
GPU vid clock 620.0 Mhz

Load with a game playing:
GPU core v 1.100 v
GPU core w 26.157 w
GPU clock 1759.0 Mhz
GPU mem clock 1752.0 Mhz
GPU vid clock 1582.00 Mhz

So not sure if I should set a flat line or what is a good curve/frequency/undervolt to use.

Thanks
