But changing the clocks with NVIDIA inspector doesn't work on the 750ti. Only the 970, 980 ++ cards
You sure about this sp_?
I don't have any 750 TI cards anymore to test this out, and coincidentally, I was also using EVGA's PrecisionX when I did have them, so I don't have any personal account either way. A quick google search found me some hits showing posts from people that reported using Nvidia Inspector with the 750 TI to enable/disable performance mode and other stuff.
