I'm running 10.7.3 on Gigabyte EP45-UD3R, 4GB ram, Core 2 Quad QX9650 (no OC), MSI GTX 570.
I can set it up fine. Everything works, Dual monitors (DVI) recognized by Lion, in System Report, properly.
Benchmark numbers are okay.
BUT what i can't fix is random graphics glitches: Text Editor, Safari opens in a smaller-than-normal opaque windows, or "invisible" windows, etc, like 1 out of 3 times. It is random, but can be invoked immediately after boot. Safari scrolling has a lag after a while. Video playing is not always smooth.
I have tried Kakewalk, all kinds of Beasts, etc. I'm using as few kexts as possible. PciRoot=1, GraphicsEnabler=1, npci=2000, darkwake, etc.
Tried CLenabler, Nvidia drivers, Mac built-in drivers, CUDA, etc.
Deleted AppleGraphicsManagement, same. I'm on simulated MacPro3,1.
It is driving me crazy, wasted like 20 hours on it, or more. Mountain Lion: it installs, but at first boot, i can hear the music, but the monitor goes to sleep. Did not try many things there (ML) yet.

Any serious ideas WHY this can be? Random, not predictable artifacts. Usually a KP is coming along with them, but not always.

Please, just experienced users should answer, i have read and tried what a normal person could do, I'm not a newbie.

Have you tried runnign windows and strees testing the 570 to see if its a bad card?

boot -v and post one photo KP

Does this happen in other OS's?
I recently had a 480 die on me, it's whole life it had given me artefacts, didn't like to wake from sleep etc.
The replacement 480 is slower (only EVGA clock rather than a Superclocked one (3 points difference in Cinibench)) but has never given me artefacts always wakes etc.

Upon closer inspection, one of the caps one the old 480 had a dry joint so I cooked it...still need to test it to see if it fixed it.

Could be a dodgy GFX card..it wouldn't be that uncommon.

Playing in Win7 64 bit it never gave me any errors or artifacts. I will do some more tests, but what are the best ones for testing card stability? I used furmark in the past, it could handle it. Doesn't an IntelBurnTest/Lynx - like test exist for GPUs? That would test if the card can come up with the same result every time a certain calculation or task is given to it.

I will check this out, complicated but worth it if it handles my problem. I will also create a foto if these dont solve it.

Can be, but it does not give me errors under Win7 64 bit. Under XP sometimes yes, I have just reinstalled clean Nvidia drivers to see if it goes away. Also under XP the power management is different. I have two monitors hooked up, and this way there is no low power state for the card under XP. It is a driver restriction... Hmmm. Maybe this explains it?? I need to experiment some more!

SOLUTION:

 

"TSCsync cpus=1 issue permanent fix ML"

 

http://www.osx86.net...ent_fix_ml.html

 

This handled the problem, all CPU cores are working, no graphical glitches, no lagging, no KPs anymore. 

 

I'm using iAtkos ML2, during OSX install, tick this: "TSCsync patch" to install. Now I understand why it was a built-in option...  :)

 

The problem was NOT caused by the VGA card, but my missing Time Synchronization between cores, the clue was this: booting with "cpus=1" or "cpus=2" made the system perfect... Some Googling resulted in the solution above.

 

PROBLEM SOLVED!!!
