[Solved] Nvidia Web drivers (GTX 1080) not being used with Z370 and 8700k

[famous_dallara]

Hi there. My system was running fine. My specs were:

- GA-Z170X-UD5
- 6700k
- Gygabyte GTX 1080 G1 8GB
- Samsung 960 EVO 500GB (NVMe)

Everything was running smoothly, but I decided to upgrade to Coffee Lake (i7 8700k) with the Gigabyte Z370 HD3P. I swapped out my motherboard, installed the new CPU and my Samsung 960 with my current High Sierra (10.13.4) installation.

Everything runs OK, but somehow my computer is not using the NVIDIA Web Drivers when booting up. I do have the nvda_drv=1 flag during boot (and it used to work with my 6700k and UD5), but it doesn't work with my new motherboard and Coffee Lake. Also, I updated the web driver to "387.10.10.10.30.106" (before swapping my MB and CPU), the latest compatible High Sierra 10.13.4 version.

Do you happen to know a possible fix so I can get my system to boot using the NVIDIA Web Drivers?

Thank you for your help!

Sounds like an NVRAM problem. Try using AptioMemoryFix.efi instead of OsxAptioFix2Drv-64.efi.
