Mac Pro Graphics Cards in G5

[bunnspecial]

Does anyone know if PCI-E graphics cards from a first generation Mac Pro will also work in a Late 2005(PCI-E graphics) G5?

From what I've seen, the Mac Pro cards are more available and(slightly) less expensive than the PCI-E cards specific to G5s.

The ATI Radeon X1900 may work, but it would need to be flashed first. I seem to recall that it didn't work, even after flashing it with the OpenFirmware/PowerPC ROM.

Thanks...sounds like if I want to upgrade, I'd be better off to look for the G5 cards.

I flashed a PC 1900XT card. Cost peanuts and is working in my G5. Mac equivalents still carry a premium.

Do you by chance have a guide or link to the appropriate files and procedures for that flash?

You need to get a fairly early version of atiflash and find a host PC to do the flashing. While it appears that you can flash on a Mac using Graphiccellerator, it did not work for me when I tried flashing a card on my Quicksilver.

The card I actually flashed was an X1950XT and the ROM for that is not to be found on the link above. The rom I used was found below

Make sure you get an X1950XT with a two lane cooler. Check the images on the Macelite site as there are various versions and not all lend themselves to flashing. You sacrifice a PCIe lane but the card is much quieter than the slimmer ones.

Compared with flashing bioses, flashing gpus is a very quick process with minimal feedback. Blink and you miss it.

Very informative!
