[Fabreeze]

Hi every one.
I decided building a customac and followed many guides with same results.
Installed Sierra with multibeast method.
After install i boot from usb to freshly installed to do post install stuff with Multibeast.
While i do this everithing seems to work fine, even eth access.
As soon as i reboot, eth stops working and no way to install alternate nvidia drivers.
Here's my pc hardware.

MB: Asus x99a 3.1
Ram: corsair vengeance ddr4 2*16gb
Cpu: intel 5820k overclocked at 4.6ghz
hd: samsung 500gb magnetic drive(i mean no ssd) for sierra.
Psu: enermax Modu80+ gold
Gpu: Gigabyte nvidia 980ti gaming g1.
Any help appreciated to make things work.
thanks in advance

Edit: just noticed the cpu is identified as a xeon 6 cores

After a few more struggling it seems to work fine except for audio.
Tried both Voodoo and ALC1150 (it should be my MB audio chip)
Anyone who got it to work?
Still having cpu misread as a xeon instead of a 5820k and not at full speed of 4,6 ghz

I hope those files can help you. This is my X99 Asrock extreme 4 files maybe little different u have to change by your own. Use Kext Utility install Realtekalc.kext and put realtekalc.kext in EFI, then restart run Audio120_v1.0 command than restart all set. I hope those 2 files will help you install audio.

Thanks for the reply, tried your method but didn't work.
Btw solved installing Realtek alc1150, simply selected the wrong audio output
Up to now everything seems to work seamlessly, only 1 issue left, my i75820k is still seen as a xeon 6 cores.
Gpu working
eth working
audio working
usb3 working
