Gigabyte GA-Z97X-UD5H / Yosemite 10.10.4 / Clover - Constant Freeze/Crash Problem

[flewid]

so i take it your not booting from EFI partition then did you format it to Fat32?

not sure on the first part, i do have an EFI partition, that isn't mounted on boot, but i can go in and manually create /volumes/efi and mount it as msdos, make changes to config.plist, save and unmount, then reboot and the changes come with the reboot (inject nvidia worked in that way).

you need to format the EFI to Fat32 then run Clover again and edit your Clover.plist with Clover Configurator thats how i do it anyway and it works doing it that way

so id recommend following the 2nd part Post Installation 10.10 Clover Guide

Sorry I must have misunderstood you, I've already done this portion of the post installation steps.

So,

Good news - Overall, the system is working WAY WAY better now that I've disabled turboboost in the bios, removed the nvidia injection, and used the default os x drivers for the video card.

Bad news - she's still freezing, but much less, and it's always the same error now, which is attached. But it'll work for an hour, maybe two now instead of only minutes, so that's a lot better.

It seems to crash / freeze whenever I load something graphic intensive, or even too many images at once it'll crash. Could also be related to power management maybe?

I also can't re-enable my nvidia web drivers, just crashes on boot now for some reason -- then reboots itself twice more and i'm back to old drivers automatically.

Also the 'about mac' doesn't show the actual video card (just says Nvidia Chip 2048mb) but I assume that's because it's not using the Nvidia web drivers?

I'm attaching the output now of what it says when it crashes.

If your card still isn't being reported correctly there's an issue surrounding your GPU. When I had a GTX 770 which is supported natively it correctly reported the VRAM and GPU name in 'about this mac'.

Can you post screen shots of your BIOS settings?

Yeah, I'm actually a little confused about this, because previously it was reported right (I believe, right up until i changed the bios settings from 1333mhz to 1600mhz ram, and ehci = enabled (instead of disabled). I'm like 99% positive it was fine previously to that.

Now, I have gone and strictly disable / uninstalled the nvidia drivers. However, I'm still getting crashes related to video (now it's straight up crashes usually, like just working along, then computer reboots itself).

It is MUCH more stable than it was before cause I can generally just work away but then it will crash if i open too many images, or, too many tabs, etc, always with a problem 'related' to graphics it seems.

So, I think my issues lay with the graphics now that Turbo Boost is off.

Just to re-confirm, current settings are;

• nvidia web drivers - uninstalled
• bios set to defaults
• turbo boost set to off in bios
• ehci set to enabled in bios
• onboard video set to off in bios
• ram set to default 1333mhz in bios (instead of 1600 profile1)
• nvidia control panel no longer shows in preferences pane
• about this mac says "NVIDIA Chip Model 2048 MB"

I've been reading others have fixed this by installing the web driver and using that -- but, I just uninstalled that so I'm not positive that needs a reinstall, and like I said no gaming, so if going with default settings is best I'd rather do that.

I know we're close here, it's the most stable it's ever been and just seems to be graphics related at this point.

Along with these bios shots, below that I have included the latest graphics crash logs. Let me know if you need more settings photographed;





I'm still experiencing crashes, always related to video as the attached logs will show;

 

[VioletDragon]

maybe your graphics card is defective have you tried booting with integrated graphics to see if it still crashes?

i have not tried this. Should I be taking my card out entirely, and then enabling onboard in the bios and booting again?

 

[VioletDragon]

enable onboard first make sure its set to 64m then make sure your injecting intel in Clover then take out your card and plug in your monitor to onboard graphics if it boots to the desktop and no crashes then its either a kexts issue or a defective card. Make sure so boot with -v i forgot to mention also disable vt-D having that enabled causes kernel panics also
