How to make friends GeForce GTX 650 and Hacintosh?

Question

NVIDIA

CPU: Core 2 Duo E8400 3.0GHz
Mother: ASUS P5Q
RAM: 5Gb
and actually GeForce GTX 650
Bootloader Clover
Installed Nvidia Web Driver and assigned it, after booting nv_disable=1 , otherwise the monitor just went out.
I restarted the PC and started loading with the parameters GraphicsEnabler=Yes/No -x -f -s nvda_drv=1 , tried everything, but to no avail, the monitor on the graphics output (after the OS startup logs) just goes out.
By the way, the system sometimes (depending on the launch parameters) for some reason determines the video card correctly, but it has 0 MB of memory.
I dug in the direction of NVCAP, made a ROM from GPUZ, but NVCAP Maker does not give out a number, there is some heresy about donation in the window (I tried versions 1.4 and 1.4.2).
I sinned on the problem with AGPM (power management), but after resolving it, the problem with the monitor going out remained. Loads only with nv_disable=1 , they say the 650th is friendly and everything should be ok, I don’t know what to do already
