I recently purchased an ATI 9800 Pro Mac Edition 128MB card. I downloaded the ATI Displays software then followed the instructions of installing the card into my G5. But, when installed, nothing comes up on the screen. I've plugged into the VGA and DVI ports (using a DVI to VGA adapter) and nothing shows up.

I read that resetting the PRAM may help but couldn't get that to work at all. I can reinstall my old card and get the display to work.

Any suggestions?

Can you boot from another volume? (Install DVD etc.)?

I assume that card should work out of the box with Mac OS X Leopard, i.e. no extra drivers / software needed.

I tried the safe boot option but that didnt work.

Currently i am using the CD drive power cable for the card (until i get a splitter) so i can't use the CD drive. I am running 10.5.8 which should have all the ATI drivers preinstalled.

OP, few questions for the start:
– which G5 it is?
– do you get chime?
– PRAM reset doesn't work (i.e. you can't get second chime)?

Some troubleshooting tips:
– triple check power cable which feeds power to the card – maybe plug had loosed
– reset PRAM using old card then put back 9800 and test
– connect to G5 via screen sharing if you have another Mac and see how System Profiler recognizes 9800

Post pic of the card, esp. sticker on the back with product number.

Its a G5 DP 1.8 Ghz. 2.5 GB ram (4GB max) running 10.5.8 (early 2004?)

With the ATI card i do get the startup chime. I cannot get it to reset the PRAM with the old card either (no restart or second chime). Is there a firmware password that is restricting that? How do i fix that?

the card is the ATI 9800 Pro 128 MB

I did just get the PRAM to reset i believe. I removed some of the RAM. Prompt came up with the old card installed to restart the computer or power down. But after that i installed the new card with no success still.

Card is not a Mac Edition. It's a PC DELL or Compaq OEM part. If it looks exactly like on picture (16 RAM chips or 8 on one side), it isn't even flashable.

Return it if you can, because it's not what you wanted to buy.

Dumb. Is 109-a07500-00 a Mac Compatible PN? This is what the seller listed. Is there a website that states the PC and Mac card PN's to show extra proof?

http://apps.ati.com/102lookup/ ATI products decoding site but it will not decode 109 number because it isn't ATI number AFAIK.

Again: is this card exactly that same as on pic you've posted? It's important.

Provide as much info as you can, otherwise I wouldn't be able to help. Post a link where did you buy it.

One general rule: if 9800 is genuine Mac one or proper PC version flashed with proper ROM it will work in any AGP G5 plug'n'play. If it does not, possibilities are:
bad card
improper ROM on the card (flashed one)
improper card to be flashed (non flashable one)
No other possibilities.

I was able to contact the seller. He apologized that he screwed up (meaning that he knew the card was not the correct one). I am returning the card and he is reimbursing me.

Thank you so much for helping me out. I'll use the information you have stated to make sure if I buy another card that it is the correct model.

My card looks more like this. Either way, i was having tons of trouble trying to get this thing to work I just decided to return it and deal with getting a good card another time.
