EVGA Geforce GTX 980 Ti -> Black Screen on Boot

[flat0ut]

Weird how it wasn't in the config.plist, but it showed up in boot arguments when inside the Clover menu's on boot. I ticked it off in the config configurator, but it still goes monitor off midway through boot.

I followed this guide ( http://www.tonymacx86.com/yosemite-desktop-guides/144426-how-install-os-x-yosemite-using-clover.html ) when I put together the OS install, following the second post to fill in the SMBIOS with values from the imessage_debug app.

Should I be using something else to build out my SMBIOS values?

Use Clover configurator.

Right now you have the board id of an iMac the system Id of a MacPro3,1. You are using a valid and registered with Apple Care serial number for a MacPro3,1. Unless that is your serial number from a machine you own, you should change it. Here is an example of a complete MacPro3,1 SMBIOS for Clover.

Personally I use an SMBIOS for an iMac14,2. It better fits a Haswell system and works perfectly.

Appreciate the help. I'll give it a run through with a MacPro3,1 SMBIOS, and try the iMac14,2 too and report back.

If you are using mac pro 3,1 it is ok, but for imac, it is not. I prefer using clover and newest imac smbios settings due to full compatibility imessage etc. So for newer system specs, nor vga nor hdmi are not 100% supported. It depends also that your custom pcb vendor uses which connection layout. Sometimes you have no issues with hdmi, sometimes it will cause complete system freezes. Sometimes it's ok with 1 monitor, but with 2, it will kill the system.

Also try to turn off igp, it sometimes messes up the build if the smbios is not setted up correctly.

I had the same problem (dell U2515H) is solved using only the UEFI mode in the bios , but it works if you use clover http://www.tonymacx86.com/graphics/167774-nvidia-780-boots-into-black-screen-monitor-going-into-power-save-mode.html
