Yosemite DP 8 - nVidia resolution/performance problems

Hey All,

I'm currently running Yosemite on a GA-Z87-UD5H with a nVidia GTX 690.  The install was a breeze (I followed http://www.insanelymac.com/forum/topic/298458-installation-guide-for-1010-dp1-usb/), and the only kext I needed to add was FakeSMC.  

 

The system boots fine and appears stable, but graphics performance is abysmal (As in the desktop renders at maybe 1-2fps) and the screen resolution is incorrect.  I've tried disabling nVidia injection (I read that the 6xx series cards did not need it) in config.plist and also installing the nVidia Web Driver for DP8 - nothing's worked.

 

Are there any steps I'm missing?  I've googled pretty extensively and am drawing a blank at this point.

 

As a side note, my Yosemite install will reboot during boot (No KP as far as I can tell) exactly every other boot - completely predictable.  I'm guessing maybe some kind of dirty mount or something, but has anyone else ever seen this?

are you sure your chip (the 690) is supported?  I have a 660 gtx and am having no issues. the reboot every other boot is the kernel cache system trying to add things to your cache, your system not responding and then it restarting with the old cache.  my thought is that you are running a non supported gpu that it tries to load the kexts, fails then restarts without them (you get the very basic vid driver) until you reboot and do it al again.

 

to confirm this check your system info. if the Graphics is not listed as 

NVIDIA GeForce GTX 690 XXXX MB

 where XXXX is the gfx ram then you do not have the kexts loaded for it.

 

hope this helps troubleshoot it.

Ah, gotcha - I've done some research, and the GTX 690 does appear to be supported on 10.9 (Multiple Reddit threads seem have confirmed it was working on various 10.9.x builds).

 

It's definitely possible it got dropped from Yosemite for the beta though.  I figure I'll try and install Mavericks tonight and see if I have any luck, as you said it'll help debug if it's a driver problem :)

 

As for the system info, it's very odd.  The card shows up twice (Which kind of makes sense given that it's SLI), with card #1 having 0mb for the gfx RAM and card #2 having the correct value.  Looking at system report/extensions I see the built in nVidia kext loaded, but as you said, my guess is that it isn't compatible with my card

if the 690 is one of the SLI built in cards then it could be that it needs the (special nvidia driver) to work properly they have a download that handles the other cards beta doesn't have the (Web Driver) so it will have bad performance.

So a quick update here.  I installed 10.9.0 (Using [url="http://www.insanelymac.com/forum/topic/279450-why-insanelymac-does-not-support-tonymacx86/"]#####[/url]/[url="http://www.insanelymac.com/forum/topic/279450-why-insanelymac-does-not-support-tonymacx86/"]#####[/url]), and everything worked perfectly out of the box.  I then updated (using the combo updater) to 10.9.5 and my system started exhibiting the same symptoms as  10.10 (E.g. incorrect GX memory listed, wrong resolution etc).  Installing the 10.9.5 Web Driver didn't help there :(

 

I've reinstalled 10.9.0, and tonight I'm going to go through the updates one by one (e.g. 10.9.1, 10.9.2) and see exactly *which* breaks things.  Hopefully that'll help me debug - I'll report back and keep updating this thread in case it helps anyone else having similar problems!

Closing the loop on this, in case it's helpful to anyone else.  

 

I started by installing 10.9.0, which worked perfectly.  I updated to 10.9.1 and everything was still good.  Next, I updated to 10.9.2 and everything broke.  Confirmed it remained broken with 10.9.3, 10.9.4 and 10.9.5.

 

I finally discovered a workflow that fixed it for me/my board.  YMMV, but adding here for posterity.  I was originally using the F7 BIOS version for my motherboard, with a bunch of changed settings.  As a last ditch effort, I updated my BIOS to the latest (F10c at the time of writing), which reset my settings as well.  The only settings I then changed from default were, "Enable integrated graphics" (Set to disabled), and "Enable Intel virtualization Support" (Set to disabled).

 

Whether it was the update or the settings reset this solved my issue - card works perfectly at full resolution without having to use any kernel flags at all!

Sorry for thread resurrection, but in which OS did you get it to work then (after the BIOS update/reset), 10.9.1 or later??

Thanks.
