Several odd Graphics card problems

Ok, my graphics card is having oodles of problems, its an X1900 XT 256 MB
ATiTool does not seem able to detect its clock rates
AtiTool says the memory bus width is 64 bits
When i play COD2, or Far Cry, i get strange effects along the bottom and left side
UT2004 has some very strange artifacting, a square of some sort appears around me on the ground
i am really quite afraid of what else might be wrong

I am going to try re-installing the drivers, though i just installed 6.9 yesterday

EDIT AtiTool also reports only 8 pipelines

I agree, try reinstalling drivers and if that doesnt work just send the card back as faulty. Definitely shouldn't be having that many problems. Where did you buy it from btw ?

I agree. To the OP, go to add/remove programs, click on ATI uninstall utility, and remove. You should alos download and use Driver Cleaner Pro once you've removed your ATI drivers, just to make sure you've completely removed all old driver components. Some of your problems seem a bit fishy, so I would definitely double check to make sure you got what you paid for.
