I have this Visiontek Geforce2 GTS-V video card. It's a value card with only 7ns memory so the default clock is onhly 175 mhz core and 286 mhz memory. It overclocks to about 205/340 before visible errors start occurring. I'm even able to overclock to 218/410 but I just get more errors.
I added RAM heatsinks but no improvement. I played with AGP voltage (up to 2.0 volts) and I/O voltage (up to 3.75 volts) but nothing changed.
I've been curious why the card is stable even though 20% of the screen is filled with "white snow" (at 200/400). I wonder why it doesn't crash.
Later I was playing around with different settings in MaxPayne. Suddenly the image clears up. So I return back to the previous setting (all details) on. The snow comes back. I change back again and this time the snow doesn't clear up. I fool around with all the settings but nothing so I decide it was just a fluke. Later, testing in lower resolution (800x600), 16-bit textures, no anisotropy, no FSAA, all other LOD high, the image snaps clear again. I quit out of MaxPayne and switch back to 1024x768, 32 bit-texture (I think overclock is at 200/380) the image is still clear, no snow. The next time I use MaxPayne the snow is back, no settings have been changed.
I play around some more but it becomes harder and harder to clear up the snow. Every once in a while, 1/2 or 1/4 or 3/4 of the screen clears up. Completely puzzled by this I just stop and study the snow. I realized it is in geometric patterns and is not random. The spots are all the same size but they are arranged like spots on dice only each part of the screen has a different die. Further, I discovered some textures have "snow" and some do not, a carpet, or painting on the wall, or a doorway will be clear of snow. The snow is always white, no other colors to break up the textures. The snow is not quite static. The patterns will change even when the image is still. ArtifactTester 5 does not find any errors until I reach my maximum overclock of 218/410.
Can anyone explain what I am seeing or what is happening?
