Any tips getting my High Sierra build to recognize my Nvidia N750 Ti TF graphics card?

Been working at this for hours now, thought I'd drop it here in case I get lucky. Just reworked my Z620 workstation to boot into High Sierra, but now it's not recognizing my graphics card. I have tried both: * Following this guide on hackintosher. * Installing drivers using Benjamin-Dobell's script

Current Results:

On 'About This Mac', graphics shows: "Display 8 MB". (At some points in the process, it has said "Nvidia Chip Set 8 MB"). On 'System Report' >> Extensions: No NVDA or GeForce extensions are loaded (including NVDAStartup),

My rig is:

Motherboard: Z620

CPU:Intel Xeon E5-2600

Graphics Card: N750 Ti TF 2GD5/OC

Boot helper: Clover

OS: Version 10.13.3 (17D47)

My relevant settings are:

No 'nv_disable=1' boot flag.

Clover Graphics >> No checkboxes checked (e.g., 'Inject Intel' is unchecked).

Clover System Parameters >> 'NvidiaWeb' checked.

Clover Rt Variable >> CsrActiveConfig -> 0x67 (I set it to 1 when installing drivers).

Lilu.kext and NvidiaGraphicsFixup.kext ("special" one for 10.13.3) in 'kexts/Other' folder.

Any suggestions?
