I just got a new Dell 8400 (512 MB 533 memory, 3.4 GHz), and it came with an nVidia 6800 GTO. After going through the forums here, I found that it's a pretty good card to overclock, and since my machine's in the cold basement, I went ahead and gave it a try.
Everything was fine, temps never going above 75 degrees, until I unlocked the extra pixel and vertex shaders using RivaTuner 15.3 and O/C'd it to 400/1100. Up until I unlocked the extra pipes (even at 400/1100), 3DMark03 ran fine with no artifacting, and the temp never even hit 80 (it's VERY cold downstairs 🙂. 3DMark froze up on the first test after I had tried it at 400/1100 with a 16x1/6vp setup, so I exited, turned the shaders back off, scaled back the clock to 350/900 again, and reset my comp, thinking that all would be fine (there was no problem at this point, no artifacting in Windows or anything)
Now, however, on the right side of my screen, I'm getting green pixels in a grid formation that contour themselves to certain images on the screen. When I first turn my comp on, it's fine, there's nothing there. After time, though, these pixels start appearing in a vertical line down the center and gradually grow rightwards to encompass most of the right hand side of the screen. So if I'm playing a game, or looking at the background, they're there, annoying me to no end. Suddenly, they'll go away for awhile, only to reappear 10 minutes later (strangely, if I open an application, the app window seems to cover them up).
This almost seems like an effect gone wrong, but it's only on the right side of my screen. So, is my card toast, or is there a fix of some kind? I'll try reinstalling drivers (using 66.93 now) and see if that works, but I kind of doubt it. Everything's back to it's default settings, btw (15x1,5vp, 350/900).
