ATI Radeon 7000 Sapphire Edition anyone?

So about a year ago I bought a Radeon 7000 Sapphire that worked fine in my DP Quicksilver. I ordered another one recently from a different vendor but with the identical numbers on the back and it didn't work. Did a little research and found out that 1: Mac Editions usually had 32MB VRAM and the PC versions 64MB and 2: The PC version had a 512k ROM and the Mac version had a 1024k ROM. So I got out the magnifying glass and checked the ROMs and they were both 512s. My working Mac board was a PC card flashed with a reduced size Mac instruction set. So I ordered a five pack of 25F1024AN chips, replaced the ROMs, flashed the boards with the 2.08 firmware and made some full Mac Radeon Editions with 64MB VRAM. The PC versions are going for $19.95 on eBay if anyone is interested in doing something similar.

This is the kind of technical post I do like to read about. Very informative. Thanks for sharing it.

I flashed a Sapphire, it toke a long time of research and trial and error done, I fund a reduced size rom somewhere and one day it worked. I did it for using on a G3 MT but now have it working in a MDD 2003 perfectly well. It is 64MB and didn't have to change chips at all. I wanted to post a snapshot of the ATI control panel but don't know how. It has 2 video out and tv out. Here is what reads the Apple System Profiler: SLOT-3
Display card (Display)
Card type: ATY,DDParent
Card name: ATY,RV100Parent
Card model: ATY,RV100
Card ROM #: 113-85501-226
Card revision: 0
Card vendor ID: 1002
VRAM size: 64 MB

Ebay is selling this card at $19.95 for the pc. This card has 64MB VM works on PCI slot. You need Quartz Extreme in the Card but this card not quartz extreme compatible because this card is PCI card. If card was AGP then will have Quartz Extreme compatible. ON MDD all PCI cards must have 33 megahertz Maximum frequency or operation. Support for cards with 64 bit or 32 bit bus width. Radeon 7000 PCI 32MB don't have Quartz extreme compatible. You need software Quartz extreme in your computer for this work. I just upload PCI Extreme and Quartz Extreme check 1.1 to macintosh garden. You will these software to run on PCI cards on mac os x 10.2 with Quartz Extreme.

But what applications actually use Quartz Extreme? I am using this card in a DP 1GHZ Quicksilver. HD is a 160GB SSD Intel laptop drive in 4 partitions. Leopard, Tiger, Panther and 9.2.2/Jaguar. I have just found both the AGP slots and AGP cards to be unreliable on my Quicksilvers at this time. The 7000 can also be used in all older PCI machines (7300, 7500, 7600, Beige G3).

I've done a few of these on PCI for my beige Macs. You can put a PCI Sapphire 7000 card with the 1MB ROM chip soldered in with no BIOS into any compatible PowerMac and any suitable updater will detect the card and flash it. No PC needed, which otherwise is usually the case.

For soldering newbies, the Sapphire 7000 is a good card to practise your skills on as the ROM chip is small and doesn't require much effort to remove. Also it is isolated on the board well away from other parts. Fun fact, the PCI 32MB Mac Edition is the exact same card that Sun sold as the XR100 for its Sparc Ultra computers. It just wants a reflash between the two platforms. You will need 64MB of VRAM to get full HD resolution, however, so look for the Sapphire.

You can check your system for Quartz Extreme on mac os x. click on apple on left then click on about this mac then click on more info it will open the System Profiler then click on graphics/ Displays. It will show if your card has Quartz Extreme. Quartz Extreme will give better performance your system and playing games with 3D. There no application use Quartz Extreme in your system. Install the PCI Extreme on unsupported cards running mac os x 10.2. Quartz Extreme check 1.1 is application will check your card has Quartz Extreme compatible running mac os x 10.2. Run PCI Extreme with caution. Quartz Extreme tested on mac os x 10.2, 10.3 and 10.4 on these website.

That's good to know. I didn't think that video cards would be upgradable, or that you can flash them with different firmware.

The advantage of upgrading the ROM chip to 1024k is that the 2.08 firmware program runs on an PCI PPC in 9.2.2 (in my case a DP Quicksilver with a 16MB Video card already installed). Whereas the reduced firmware sets require a Windows machine to install. When you run the software it see the empty ROM and writes the new firmware to it. I also created something that apparently was never sold. A Radeon 7000 Mac Edition with 64MB VRAM. Flashing cards PC cards for Mac is something that is widely done. Especially since there were so few PCI-e video cards made specifically for the Mac Pro.
