7970 no Display with Clover bootloader

9 posts in this topic

Recommended Posts

I used Clover bootloader to install Mavericks to my build using the integrated graphics of my system (HD 4000) as installer wasn't giving any display. After setting up Mavericks completely and connecting my graphics card, clover boots up into a black screen (display goes on standby, if I type my password and press enter, the system works for a bit to open the mac desktop but the display stays blank). My system config is as follows:

 

Core i7 3770

GA H77-DS3H

16GB RAM

Gigabyte 7970 3GB (GV-7970OC-3GD)

 

After searching around, my card is supported by Clover and Mavericks by default, so why can't I get any display on my main card?

 

Any help would be greatly appreciated as I really need my graphics card to work with my hackintosh for editing and animation purposes.

 

EDIT: I also tried connecting a GTX 660 to my machine and booting up with the display connected to 660. The hackintosh worked flawlessly. So what do I need to do to make it work with 7970?

 

Thank you!

It seems that DVI doesn't work anymore under OS X 10.9 with a 7970. Had the same problem on last weekend and spent several hours to track it down.

 

Connect your monitor(s) exclusive with MiniDP to DP cables without any adapters. MiniDP to DVI Adapter doesn't work reliable too (i have the white Apple adapters). As recently as I connected my both monitors with pure DP cables everything worked as expected.

 

Sidenote: Didn't test 6xxx generation until now under 10.9 with DVI/DP to DVI Adapter. Would be interesting whether DVI is working on this cards…

Thanks a lot! I'll try this and let you know. Can you please tell me if HDMI works with 7970?

Not on my card (HIS 7970 GHz) with Aji Framebuffer. Only the two DP connectors are working. But I didn't dig deeper in this HDMI thing, I don't need this. Only attached a cable and give it a short try, sorry.

To anyone else who encounters this problem and is reading this:

 

Strangely enough, using a different monitor with DVI worked. So try a second monitor, or a third. Also try using different ports.

    • For F6 Bios, which DSDT is the one i should use? I´m a little confused in the Mass of DSDT here ;-).   Great Thread by the Way.   Another Question: I have 2 960Pro inside my Rig (one with OS X, one with Windows 10). When i try to mount my EFI on OS X NVMe the system freezes... :-(   DWhen i unplug the Windows NVMe everything is fine an it mounts the EFI.   Anybody an idea?   Tried the upper Port on the Board (OS X) & the middle / lower Port, in the Middle it mounts the EFI in the lower it freezes.   But i need the middle Port for an SATA M.2 SSD :-D... Even when i plug the Windows NVMe into an PCIe Adapter Card it freezes at the point i mount the EFI.   I´m mounting with Clover Configurator.     Thank You guys.
    •   Just add "ngfxsubmit=0" to config.plist to disable the fix within nvidiafixup
    • @MegaCookie   ok, I have no solution for that Trial 7 good for the release?
      Is this codec good enough for you?
    • @onejay09  - thanks again for your help and advice.  I tried various combinations of Info.plist mods (Adding a new Machine entry with my Board ID and GFX0, adding GFX0 to the MacBookPro6,1 Machine entry and adding a Vendor/Device entry to the Board ID and MacBookPro6,1 Machine entries. I thought these might make a difference, but after comparing GPU temps and frequencies to those reported in Windows 7, I'm not seeing any difference.  It appears as though AGPM is natively detecting and handling power management of the NVidia Quadro NVS 140m without any Info.plist mods.   Thanks again.
    • My rig is not booting without the "XCPM bootstrap patch" and "xcpm_program_msrs (c) Pike R. Alpha" patch. Already tested that.  Booting without the TSCAdjustReset.kex is working great and booth sleep and wake is working. The new bios 0603 has an updated microcode. That might be the reason  for the fact that everything is working as it should without the kext.
