Hi, maybe someone can help me here. Been working on this for several days now.

 

running osx 10.10.4 on a following setup:

 

mobo: gigabyte x79 up4 (rev1.0 bios version F7)

cpu: i7 3820

gpu: gigabyte nvidia 970 mini itx 4gb

ram: 32gb (8*4gb) 1600MHz Kingston HyperX Fury

hdd: 2*2tb Caviar Black + 4tb Caviar Black for storage

ssd: Crucial M4 256gb(windows) + Crucial M100 256gb(osx)

 

bootloader: clover v2 r3241

bootflags: -v kext-dev-mode=1 npci=0x3000 nvda-drv=1

nvidia web drivers: 346.02.02f02

 

everything else is working well except graphics. With my old gpu gigabyte nvidia 650 2gb it worked OOB for many months.

nvda_drv=1 flag with inject nvidia boots up and shows 0mb of vram and recognizes the gpu.

In windows everything worked well with the gpu.

 

thanks in advance

Lauri

you have a gigabyte board

 

which requires this flag

 

pcirootuid=1

 

install or add the flag to your boot loader and reboot the system

i just noticed that you use npci=0x3000

 

if after using pcirootuid=1 still don't work

 

change npci=0x3000 for npci=0x2000

Thank you, npci=0x2000 solved the problem as I already tried PCIRootUID=1 earlier which resulted in booting up without any signal sent to monitors :)

 

edit:

unfortunately it only works when I have one monitor connected via DisplayPort, as soon as I boot with 2 or more monitors I get an instant reboot after loading ethernet.

attached clover bootlog just in case

 

edit2:

nevermind, I'll make another thread pointing this multiple display issue

bootlog.log.txt

Hi, thanks you for your reply,

 

I'll try the LAN thing, but for me it seems that there is another line coming right after LAN which is displayed for a fraction of second.

extra monitors work when connected after boot.

my only boot arguments are as follows:

-v PCIRootUID=1 kext-dev-mode=1 nvda_drv=1 npci=0x2000

and they seem quite mandatory to run everything

clover automatically sets my SMBIOS as Mac Pro 4,1 - Iĺl also try other bioses

 

have been googling all day long and so far no answers for me, but will keep looking

Hi everyone, finally got it solved by using SSDT-s and Clover config.plist(with minor adjustments to fit my hardware) from Rampagedev-s X79.dmg package. Now I can finally boot with 3 Dell P2415q connected via DP and one older monitor via HDMI :)
