Mad 7900GTX!!

Hi everyone,

My friend got a GIGABYTE 7900GTX two days ago, and installed it in his rig with the latest driver.

After some small issues in games have been solved, it comes to the video playing!:

Whenever he tried to open a video file, suddenly there were white dots and lines flashing everywhere on the screen, even after he closed the file.

even he closed all the applications and restarted the system, from the moment the power was on (before Windows was loaded), the white dots and lines were already all over the screen.

when he put his old 6200tc into the machine again, all the problem were just gone, without doing anything else.

Tried solutions:
1. latest bios
2. latest nvidia driver ( 91.31 )
3. old driver with the card (84.21)
4. reboot the machine

But problem still appears. Now I remember I read some other post before says something in the bios setting I should do, but can't remember what setting. It's like put something direct to something.

Any idea?

His rig: Athlon64 3500+
1G DDR400 RAM (2x512MB)
2X160G HDD
7900GTX
580W PSU (HYPER X)

Have you touched the card to see if its hot or not? Could be showing artifacting. That means the card hasnt been adequatly cooled.

Yea, those seem like some artifacting issues.

What are temps of the card?


If your showing 70 degrees celsius or more on your video card, then you have a problem. Artificating is known to start as those temps. 75 is when it could crash. 1 of my GTXs as gone as high as 68, but that was on a humid day.

Tell me, can you cook flapjacks on that card?

Even the X1900XT will beat the 7900GTX in Oblivion, plus, you can easily overclock it to X1900XTX speed. Additionnaly, you'll be able to turn on the SM3.0 HDR + AA together. Compared to the 7900GTX, the X1900XT is a steal.

Well, temps could be a problem, but I would think playing games would make them rise more then just trying to watch a movie... If playing games is fine, but watching an .mpg or .avi causes problems, its something other then temps. What movies cause problems? If you try using another player, do you still have issues? I'm guessing there is some problem with either the video player you are using, or somehow the codecs on this machine have gone bad. Either way, reinstalling the player or codec should fix this.

I think he would be pleased with a X1900 XTX. I know I like mine better than the Nvidia GTX that I had before.

No, I don't think it's any player or codec problem, because even he closed all the applications and restarted the system, from the moment the power was on (before Windows was loaded), the white dots and lines were already all over the screen.

when he put his old 6200tc into the machine again, all the problem were just gone, without doing anything else.

112 c? my recommendation for u is to sell that card to some college student who needs to cook in his dorm. If he decides to remove the heatsink, He can boil water with your card and if he keeps a pot of cooking oil on it long enough, he could even have fries. It would be perfect, most dorms dont allow anything more than a microwave but a computer (with a over heating graphics card) is perfectly fine. And if its not hot enough.. well, he could always overclock it a bit more...

My apologies
