HI, I had the same problem, and after some reading I found that Nvidia Drivers works on Sierra 10.12.6 .
So I can not make it work with the hackintosh SIerra USB , even on updating (It did not update I dont know why)
So I just downloaded with a Mac the latest Sierr 10.12.6 and then after some struggling I can use my 1050 Gtx with the Nvidia Drivers, that is shown correctly with 2gb memory in the about this Mac screen.
So use Sierra, update clover and then I use nvidiafix and lilu.kext , oh and depending on your mother you may have to inject some libraries emuvariable and other one (I have to do this) My mother is a Gigabyte Ga H110m H Ddr4 Intel 1151.
I followed the install for Sierra method in https://www.tonymacx86.com/
Hope this helps, if there is some error please forgive me , this is my first hackintosh install.
