Upgrade with nvidia GeForce 6200?

Hi-

It's very possible, as long as you flash, or puchase a card that is flashed, to Mac ROM.
This is a ready to go card.
If you have a PC, and want to do it yourself, the resources are here.

Hi, you seem to know what you are talking about when it comes to macs and video cards. May I ask you a question?

I purchased a brand new Samsung 22" second monitor for my G5, and was dismayed to find that I could not hook it up to my computer on account of the only available port left on my card is an old ADC port and my new monitor was VGA.

I could not find a working solution (converter from ADC to vga) so I decided the next course of action was to purchase a video card that would allow me to run dual monitors using DVI for one monitor and VGA port for the other. I bought an nVIDIA GeForce™ 6200 256MB DDR2 AGP that is supposed to be a modified PC card re-engineered to work on a Powermac G4 & G5.

Well, wouldn't you guess? it doesn't work. I get scrambled screens on both monitors. Nothing seems to work. There are no drivers available for the mac at the nvidia site. Not sure what to do next.

Have I just wasted the money on this effort or is there something I can do to make this work on my machine?? Any ideas or suggestions?

Thank you!

Hi-

No drivers are needed in Tiger 10.4.3 and up. None available, thus the OS requirement for the card (uses native drivers).
It is possible that the pins are taped to allow use in a 2x AGP system. Is there any tape on the gold connectors? If so remove it. It will be on pins #3 and #11 if present.
Possible the flashing wasn't done properly. If that is the case, return the card. A reputable flasher will accept returns.
I would highly suggest asking the seller for advice.

Thank you for getting back to me.

I see no tape. What does it mean to "flash" a card? Convert from PC to Mac?

I am wondering whether it might be a compatibility issue with the motherboard on my Dual 1.8 G5 and the Apple nVIDIA GeForce™ 6200. Are you aware of any such incompatibilities?

To "flash" is to re-write the on-board writeable store that holds the controller firmware. The firmware persists across power outages.

Incompatible would be a card that was pulled out of a PC without being "flashed" with the Mac version of the controller firmware.

Thank you!

so, if I understand you correctly, if it was flashed correctly with the Mac version of the controller firmware, my nvidia GeForce 6200 card should work on my 2004 Dual 1.8 GHz Powermac G5 Tower?

If it is not working, then I can accurately conclude that it was either a defective card or one that was incorrectly flashed?

At this point, it does not seem to be working for you, and you have pursued some of the potential issues. I suggest you follow japamac's advice above:
