Hello All,
I was lucky enough to be given a new video card this Christmas (ATI
9800 Pro Mac Special Edition). Unfortunatly I am having some serious
issues.
When I frst installed the card in my G5 all seemed well, both my
displays appeared to be working properly and I did not notice any
problems. The next day I decided to update the ROM on the card to the
latest offered by ATI; after doing this I began to notice some horrible
screen artifacts and tearing.

As you can tell from the screenshots above this is not normal.
Here are some details of my Powermac:
Dual 2.0G5 w/ 3.5 GB of RAM
Running 10.4.3
Displays:
23" Apple (plastic) Cinema Display connected via ADC
17" Sony connected via DVI
And the ATI card:
Chipset Model: ATY,R350
Type: Display
Bus: AGP
Slot: SLOT-1
VRAM (Total): 256 MB
Vendor: ATI (0x1002)
Device ID: 0x4e48
Revision ID: 0x0000
ROM Revision: 113-A14402-126
I have attempted to downgrade the firmware on the card to the previous
ROM offered by ATI; no luck.
I have taken the normal troubleshooting procedures:
- Repair permissions
- Clean caches
- Repair Disk
- Reseat video card
- Install a fresh copy of Tiger on a seperate drive
- Install different versions of ATI's software (currently using the
most up to date)
- Remove ATI's software
- Boot into safemode
- Run one display at a time (first ADC then DVI)
It seems ATI support is out till 12/30; does anyone have any advice?
Thanks for all your help....
-Chris
