GTX 980 Ti + 10.9.5 pci4 [Fatal] Unknown Chipset Error shows in verbose

[ImmortalJman]

I haven't updated yet to Yosemite or El Capitan successfully and needed to upgrade to a pair of GTX 980 Ti's from Gigabyte Gaming Edition. When it boots, the verbose mode shows pci4 Fatal [unknown chipset]. The only way I can boot in is by using nv_disbale =1 flag. I have the most current drivers for 10.9.5. My bootloader is Clover, is there any way to use the web drivers to enable full acceleration, or will I need to upgrade to Yosemite or El Capitan for this to work? Thoughts.

Sadly this post answers my question.

You need to be running at least Yosemite for it to work.

So, I'll be trying to upgrade again and hope that I can get past PCI Configuration begin when I install the card back in.

Well, I finally had a successful upgrade to El Capitan and got the 980 Ti to work. For a description of the exact details, go here. http://www.tonymacx86.com/user-buil...s-12tb-geekbench-28-000-a-80.html#post1124194
