GA-Z170X-Gaming 7 Partial Success

[isisyodin]

It is been a while since I hackintoshed a PC. Anyway, the installation went OK following the latest guide. I do have a few things that are not working and partially working.
Specs:
GA-Z170X-Gaming 7
RAM: GSKILL Ripjaws 16GB (2x8GB) DDR4
HD: 2TB Seagate 7200RPM drive
Graphics: Integrated Graphics Processor-Intel® HD Graphics
Graphics External: Sapphire Nitro Radeon R9 390
Audio: Creative® Sound Core 3D chip
LAN: Intel® GbE LAN chip (10/100/1000 Mbit)(LAN1)

Working:
It boots, displays proper resolution and overall basic functionality is OK. LAN, bonjour, and video.

Partially working:
RAM: Only 8GB recognized not sure why
Graphics: Only internal which is OK for now.

Not working:
Audio: I guess it will never work since Apple doesn't use such hardware. I wonder if HDMI pass through audio would work with some tinkering.
Thunderbolt: not recognized
External Graphics: Did not boot
Overclock: Reporting 4.01GHz but system is OC'd to 4.6GHz


Any suggestions?

I made some progress without much effort. My radeon card is up and it works but system information is only picking up 14MB of VRAM. I am getting the full resolution out my monitor 2660x1440 on the Display port.
RAM is still stuck to 8GB. Will have a look at the ssdt now.
