Flash a PC X1950XTX Card?

Thank you for your reply. The site doesn't have the rom for X1950XTX or even X1950XT. Actually I have the rom for X1950XT, but I don't known if that one could be used to flash X1950XTX that has different VRAM size(512M) and type(DDR4).
I agree. That both X1859XT and X1950XTX have similar core chips(580,580+) still makes me think I could give a try when I have time.

Could you also take a look at https://forums.macrumors.com/threads/1706020/ , and kindly give me some help?
No problem, you need to find ATI FireGL X3 256MB with Samsung chips.
There is ROM on macelite website, but you have to change device ID.
You can find out your device ID easily on windows machine with drivers installed and using GPU-Z application.
To change device ID in Mac ROM from macelite, you need hex editor.
I'm afraid it won't work due to X1950XTX's DDR4 memory. Stick to X1950XT - guaranteed to work with no issues.
Thank you for your quick answer. My card is ATI FireGL X3 256M with Samsung memory chips I just looked. I tried both FireGL rom(without modification) and X800XT reduced one(changed DID in line 3 and 8 to 4A4D) from macelite website by a PC, but no success. I failed with " card rom size (00010000) < new rom size (0001E200)" error when I did it in my PowerMac G5(2CPUs) running Tiger. I wonder if the OS matters. Must I do flashing on Leopard, or in safe mode, or by no confirm flasher?
Thank you, you could be right about X1950XTX flashing.
I flashed X1950XT with a rom from you found in this forum, but I have two minor issues:
1). The GPU temperature can not sensed and monitored,
2). When I leave machine in sleeping , it can not be waked again - I have to shutdown with pressing switch button for several seconds.
Do you also have these issues with X1950XT card?
Thank you again.

Try with this BIOS. Compare Device IDs, edit if necessary and flash.
This is BIOS dumped form my flashed ATI FireGL X3 256MB, at the moment in G5 from signature as ATI X800XT.
Make sure after successful flash you install:
macosx-ati-displays-4-5-7.dmg

Thank you very much for four help. I just tried but couldn't make it. I use my G5 running Tiger 10.4.11 and follow the procedures:
1). Plugin the FireGL X3 256 card in APG slot, connect power supply and monitor. Switch on the G5.
2). Use VNC viewer from a PC to connect the OSX remote desktop. The card recognized as VGA compatible card.(see attach.)
3). Open Graphiccelerator, select ATI multi flasher and your rom downloaded above, and save. It said "OK".
4). Go to ATI tools folder, run "run me first", then launch ATI multi flasher. A confirmation window appeared, and I pressed "Yes".(see attach.)
5). A window prompted and disappeared so quickly that I couldn't catch what message on it, then another window appeared showing "Error Programming Devices".(see attch.)
I tried also in safe boot, using SSH to start Tiger's VNC server for VNC viewer. The same results as before.
What's wrong with my doings?
I'll try to flash in a PC, and report back what happens.

Success!
Finally I succeeded in the flashing! My processes are somewhat weird: flashing in a PC or in A Mac didn't work for me. I tried in a PC running PCDOS 7.10 many time using various versions of ATI flashers and roms, but all my effort was in vein and went nowhere. Some flashers(more recent ones) did report flashing success but the card simply won't work on Mac. I also found the 64K rom file couldn't be written into the card fully because the dumped file was only 32K after successful flashing! So I tried the followings using both PC and Mac, that did the trick:
1). Flash the card in a PC with bax2003's rom above in the thread.
2). Plug in the Mac G5(it won't work of course)
3). Power on the Mac and use VNC to access it.
4). Use Graphiccelerator to load the flasher and rom. When the card holds PC rom it can not be flashed as my previous posts. It holds broken Mac rom this time.
5). Run the ATI multi flasher, a confirmation window prompts up showing some differences in SSID and PINS between card and intended rom.
6). Press "Yes", a progress bar appears and finishes successfully.
7). Restart the G5. The Apple logo screen shows up and it boots to black-white screen image with some artifacts.
8). Install necessary ATI drivers and tools. It works like a charm.(oh, wait, temp is not sensed)
The procedures above work for me at least, may be they are also viable for others.
Thank you, bax2003, your help is much appreciated.

Well, not directly related to the X1950XTX, but to X1950XT: I have a ASUS X1950XT (PCI-e, 256MB, bought 2 of them on ebay about one year ago) in my G5, I was then able to flash a ROM I've found somewhere here or in another forum. Still have the ROM if needed.
But another question to Bax2003: is the ATI Displays software really needed? Can't remember to have it installed.

Similar to this one...

This looks like it's probably the answer, but it's a little way over my head.

If you want one of these cards that desperately, get a Quad and find a retail card. They're not super expensive, and are the best performing non-flashed card you can get for the Quad(and the better flashed cards fall into "angels dancing on the head of a pin" category).
