View Full Version : g5, 30 hd cimnema, radeon 9800 xt

Aug 25, 2008, 09:13 PM
bought a 30" mac hd display for my 1.8 dual core g5 power mac running osx 10.4.11. The card in my computer only allowed me to get 1280x800 resolution. I upgraded to the ATI Radeon 9800 xt mac to power the display to get the optimal resolution of 2560x1600.

I bought the following on ebay:

Product description is: Mac ATI Radeon 9800 XT 256MB Video Card G4/G5 Edition

I put the card into my computer and still only got 1280x800.

So I installed the following software updates:

I am still only getting 1280x800.

Furthermore both my system profiler and Ati control panel info profile seem to think the 9800 Pro with 128 ram is installed -- rather than the 9800 XT with 256 ram.

System profiler says:
ATI Radeon 9800 Pro:

Chipset Model: ATY,R350
Type: Display
Bus: AGP
Slot: SLOT-1
VRAM (Total): 128 MB
Vendor: ATI (0x1002)

Revision ID: 0x0000
ROM Revision: 113-A07525-130
Cinema HD:
Display Type: LCD
Resolution: 1280 x 800
Depth: 32-bit Color
Core Image: Supported
Main Display: Yes
Mirror: Off

Quartz Extreme: Supported

Did I install the wrong ROM update? So now the computer thinks its a different card?
How do I reverse that?

The card looks like the XT not the PRO -- when I compared it to pictures on the web.
It looks like this:

Is the 9800xt the same as the x800xt?

Why does my machine say I have the PRO installed?

Is there newer software that I need?

How can I get the 2560x1600 resolution?

Help please.
