Default Graphical artifacts with 8800gtx and 9742

Hello There,

Approx. a month ago, I bought myself a shiny new Geforce 8800gtx with my new system (evga nforce 680i, intel core 2 duo 6600) and everything was working just fine, with my linux and the nvidia-drivers 9742), until today.

The problem I'm experiencing is as followed:

- The system starts just normal
- after i loginto my X Session and work or play a game (WoW for example), after approx. 20 - 30 minutes I get small quadradic graphical artifacts which look like "static" in color and then the screen gets really messed up with colors and so on
- I then have to login via ssh or access the console (after hitting the SysRQ magic key) and kill the X Server

- From that point on, the X-Server won't start again (the X Server log is attached to this message)

- After rebooting the machine the X Server starts but the artifacts return much faster, approx 1 - 2 minutes after the X Server has started.

When the artifacts start to appear dmesg reports these "errors":
---------Dmesg.snippet---------

---------Dmesg.snippet---------


My guess is that it's some kind of hardware problem (maybe memory) but I just want to be sure and check if one of you guys have an idea.

Any help or suggestion is highly appreciated and I wish u all a happy christmas.

Greetings, Marc

That sounds like overheating to me. What kind of temperatures does the nvidia control panel show after the graphics have freaked out and you have rebooted?

Thank you for your reply.

That's the interesting part. After the machine has rebooted the nvidia-settings tool shows that the gpu is approx. 79 Celsius, which is like 174 Fahrenheit.

This is the same temperature which is reported during the graphic freakout. But right at this very moment I had another lockup and the gpu was "only" 70 Celsius (158 Fahrenheit).

The same phenomenon happens in windows xp. I can play for like an hour sometime and then the graphical freakout starts, but of course windows then ends up with a nice little bluescreen.

It sure looks to me, that at some point either a memory chip or the gpu itself got overheated and since then behaves that way.

I have seen alot of things in my life, but never ever that a Graphic Card gets overheated in my systems (my current system is well cooled with 4 large coolers, of which one is only attached to cool the gpu).

FYI: Dual Quadro FX 5500 run at 46C in my (Boxx) system.

Thanks for the information.


Okay, 46C would be an awesome temperature. :-) But I just don't know why this thing gets so hot, i mean my CPU is 35C and my Mainboard 29C warm.

Only the GPU starts at 58C. :-(

I've just tested another thing, which proofs that my problem is not caused by overheat.

With RivaTuner I've pitched the gpu cooler to 100% rather than auto-adjustment and the gpu temperature didn't cross 56C while gaming and then *boom* the artifacts again.

I'll go to the store tomorrow to get a replacement, I just hope that it's no something else... :-)

I'll let you know how it goes with the new card.
