nvidia GTX 570 pink screen flicker

[sirNemanjapro]

I found several topics concerning my ASRock motherboard and it helped me a great deal. I flashed my motherboard and fixed almost all problems I had. However, I cant get GTX 570 to work properly under Mac OS Mountain Lion 10.8.0 and 10.8.2.

The graphics card is fully operational and working 100% (Windows/Ubuntu), but in Mountain Lion, few minutes after logon I get pink flicker (for a fraction of a second) and everything freezes except the mouse. I believe this might be a software issue, well, driver issue.

I have noticed that after logon, GPU clock goes down from 7xx Mhz to 50 Mhz. o.0

Do you have any ideas on what could work for me?

I have tested the system by running two QuickTime .mp4 videos, Photo Booth, Chess, Safari on YouTube, Firefox on YouTube and Mail active, all at the same time. And everything worked without any problems.

Once I turned everything off, and just used Skype and opened Firefox to upload something to imgur, there was a pink flicker on screen and everything froze, even the mouse.

What exactly did you do (or install) to get your graphics card running?

Post the result of your

$ bdmesg

here with CODE-Tag...

I have nVidia GTX 570, not from an OEM manufacturer so... I just applied what came with multibeast. That worked up to the point.

That is your problem. There is nothing to install for 570 in mountain lion. Try a vanilla installation...

 

[sirNemanjapro]

I am using vanilla installation, and the screen flickers, as described. Drivers didn't help either.

 

[smolderas]

With vanilla installation I mean, there is no need to install anything for Geforce 570. No drivers, nothing...

That doesent work for me. My system keeps freezing, with pink lines/pink screen flicker. So something is not right.
