Ti4200 Issues...

[Cobra]

My Ti4200, started turning Yellow my desktop color and if the memory runs to high, it's turns pink some colors on any 3d stress test.

I tried underclocking, the yellow gets worst but the pink stops...

Any ideias WTF happened???

I know it's the O/C on the video card, cause my 12 Mega Monster 3d, was my first O/C and started with the yellow trouble when I O/C to much...

Did I corrupted any thing on the ti4200???

My benchmarks didn't lower at all but sometimes it turns yellow for no reason... If I underclock too much, it gets worst, a little gets a bit stable but it is still a random error...

It is possible that the longterm effect of being overclocked has managed to damage some of the components on the card. Obviously I'm no expert but it is a logical explanation, unless something else has occured to affect the card (such as dropping your case LOL).

Honestly, it doesnt sound like a video card problem to me. While overclocking does make a card run hotter, it usually DOESNT reduce the life of the video card by a significant amount, since the heat production is well within tolerance. Increasing the voltage can cause damage to occur quickily to the transistors on the GPU. Most video card overclockers dont volt mod their video cards so this isnt an issue.

The second issue has to do with the coloring you see. When video cards die, you can see a variety of different issues. The most common is artifacting. Less common are problems involving color channel and image distortion. These last two problems are caused by dying parts on the video card NOT related to the GPU overclocking.

Its hard for me to tell what your seeing based on your description, but because you mention this yellowing problem occured on another of your video cards, and it would be rare for two cards to die like that, I dont look at the cards, but I look at your monitor, cables, or even a software issue. Try another monitor and set of vga cables (if necessary). Do you see the same color distortions on that?

The fact that it reacts different at different speeds is odd. I dont know if I can explain the pink showing up. Are certain colors replaced, or does the whole screen take on a yellow or pink hue? If its the whole screen, then usually your missing a color channel signal to the monitor (such as missing Blue for yellow tint, or green for pink tint). Maybe its a loose VGA connector :)

Thats not to say its not a GPU or Northbridge problem. It could be a weird driver bug, its hard to tell from here. None of that seems likely to affect color output. Artifacts yes, but color output is is left solely to the RAMDAC (http://www.webopedia.com/TERM/R/RAMDAC.html) on the video card, and this is rarely, if ever, faulty. And you cant affect it by overclocking.

The other video card that had this issue was in PI MMX 200 7 years ago.

I think my ram might be f... up cause when it comes to the horse benchmark, it won't render it completely...

And the pink comes when rendering the water in the CS:Source Stress Test.

Since I live by the beach, the salt could have corroded the VGA connector?

you can try to clean the agp contacts with a q-tip and alchohol and blow out the socket with air, i have had similar issues in the past but most were solved by re-seating the card a few times.

is the correct icm profile loaded for your monitor, most people dont bother but i float between the viewsonic g771 profile and an adobe CMYK one.

also i dont think dielectric grease will hurt the 15 pin vga connector if you want to prevent corrosion from the sea air. but get a second opinion JIC:)

its the monitor i know a guy that had similar problem but his went green and blue very weird how he didnt mind to keep playing on it.

Only time I've personally encountered a problem anything like that, it turned out to be down to the monitor cable.
