All Problems with GTX 970 and Yoseite

I am having problems with my Gigabyte Gtx 970 getting detected by Yosemite install. I have tried too many methods here and there to make it work and because I am a beginner and learning new things with each combination, I am repetitively failing to make that happen.

 

So here are few things I did which are not working as expected:

1) I installed the appropriate drivers and tried to boot up with loading nvidia drivers from preferences center but that didn't worked.

 

2) I tried injectEDID, InjectNvidia and LoadVideoBios from clover bootloader option and also with the flag kext-dev-mode=1 but it failed to work. In 'about mac' it is showing gtx 970 "0"mb vram. Monitor works so slow that I can distinctly see each buffer and screen refresh every time.

 

3) I used additional boot flag nvda_drv=1 to make it detect the VRAM of the GPU but after the apple logo, monitor went black showing "NO SIGNAL" error where I have turn off the power supply to restart the system.

 

Please would anyone guide me to make my 970 work with Yosemite.

ram 0 mb most like you have a gigabyte board like me

 

you have to use or add this flag to your flags

 

pcirootuid=1

 

i don't use clover

 

i use chameleon

 

you have to know where to put the flag in clover

 

or look for that flag in clover options

 

anyway these are my flags in chameleon

 

<key>Kernel Flags</key>

<string>npci=0x2000 kext-dev-mode=1 dart=0 nvda_drv=1</string>

<key>PciRoot</key>

<string>1</string>

 

if you don't have nvidia web drivers installed

 

you have to boot with nv_disable=1 

 

after you install nvidia web drivers then you don't need to boot with nv_disable=1

 

but make sure nvidia web driver is selected in nvidia driver manager

 

with nvidia web drivers installed nvda_drv=1

 

without nvidia web drivers installed nv_disable=1

 

hope you understand

All those sleepless nights have came to an end. That boot flag worked.

Thank you so much man.
