J P Kogelman Posted January 13, 2007 Share Posted January 13, 2007 I'm trying to install an 8800 GTX into a Mac Pro, replacing an 7900 GT KO. I seem to be at a loss as to where to get the extra power for the video card. I modified a 4pin to 6pin cable and attached it to the extra feed on the DVD (I only have one optical drive thus the spare connector). But the 8800 requires two power feeds and won't boot without it. I see there are two PCIE_B1/2 connectors on the motherboard near the PCI-E slots, but haven't seen a cable that would connect to a PCI-E card. Any suggestions?? Thanks!

J P Kogelman Posted January 13, 2007 Author Share Posted January 13, 2007 I was able to find a connector that would work, should anyone else be seeking the same thing, check this site: http://www.welovemacs.com/9227128.html Link to comment Share on other sites More sharing options...
rlpc8 Posted January 14, 2007 Share Posted January 14, 2007 Are you replacing the MacPro graphic card with normal PC version 8800? Supposingly, Mac is using EFI and PC is using BIOS and therfore the firmware on the Graphic card should be different. Besides, the OSX does not come with 8800 driver. It is therefore I am still hesitate to change from a PC to a MacPro. Can you please continue to update youe result to us. Thanks in advance Link to comment Share on other sites More sharing options...
Soündless Posted January 14, 2007 Share Posted January 14, 2007 what about titan/natit? Link to comment Share on other sites More sharing options...
eggie Posted January 14, 2007 Share Posted January 14, 2007 i didn't think that supported something as new as the 8800 series..... rlpc8 is right the firmware is different in mac cards than pc cards, and its difficult to re flash pc cards to work on a mac you need a special hacked firmware and there is a whole lot of rubbish you have to go through to flash it Link to comment Share on other sites More sharing options...
macgirl Posted January 14, 2007 Share Posted January 14, 2007 There is a report post on the Natit Forum that it works but only if the original graphic card is installed on the first slot. Link to comment Share on other sites More sharing options...
J P Kogelman Posted January 14, 2007 Author Share Posted January 14, 2007 I should state I am only running my Mac Pro as a Windows system, I don't have a Mac OS installed. From searching for the power issue I ran across a number of posts that say you have to remove the other PCI-E cards and just have the 8800 installed. Now if you plan to switch back and forth, this is not only a pain, but could lead to damaging your Mac Pro motherboard. There are a few alpha/beta drivers out there, but I'm afraid I have little interest personally to test them. When I need to work on the Mac OS, I have my trusty MacBook Pro available. The best information I have found is located here, and there is chatter about Mac drivers, hope it helps: http://forums.macrumors.com/showthread.php?t=250851 Link to comment Share on other sites More sharing options...

I don't even think the MacPro has 16x pciX slots they are all 4x. That is a waste of a system to screwing with windows, and I don't even own a mac.

That is a waste of a system to screwing with windows, and I don't even own a mac. Ohh well Actually the mobo on the MacPro's does in fact have 16x PciX. Here's a quote from the graphics section on Apple's MacPro Buy & Config page: "A 16-lane, double-wide PCI Express graphics interface supports the latest graphics controllers for up to 4 GBps of data throughput. And by supplying up to 300 watts of total power to all PCI Express slots, the Mac Pro provides the headroom for high-performance, next-generation graphics cards." Note that in order to have seen that you have to hit the learn more tab. P.S. That is a waste of money to be running Windows exclusively. Do you not like OSX, JP? Or are you just afraid to make the switch? I have a feeling that you are using it as an game machine. If that's the case why not just use Bootcamp and get the best of both worlds? P.S.S. Are you planning on playing Crysis? If so, you should let us know how it runs on that rig. Link to comment Share on other sites More sharing options...

J P Kogelman Posted January 30, 2007 Author Share Posted January 30, 2007 Sorry, been busy at work...and haven't had time to read nor post. I have no issue with the Mac OS, but I do enjoy games when I'm not working. Most of what I play is not available on the Mac OS; WoW is, but NWN2 is not. Last time I checked CoD 2 or 3 were console or Windows only. Also I do work from my home machine and need to remote into my AD servers, etc... and I need Windows for that. At the time I purchased the Mac Pro, the Core 2 prices for the processor I wanted was higher than buying the Mac Pro. Add in the fact I enjoy the design of the Apple computers, and finally now they can run Windows ... I am a happy user. To complete my Mac Pro, I just added a nice 30" ACD ... this is one very powerful work station/game rig =) Link to comment Share on other sites More sharing options...
u1m2 Posted January 31, 2007 Share Posted January 31, 2007 Mac Pro is excellent bang for buck and I don't blame him for buying one even if he just uses Windows on it. It's an awesome workstation for a very good price. Link to comment Share on other sites More sharing options...

Shen Long Posted January 26, 2008 Share Posted January 26, 2008 I purchased a GigaByte 8800GTS & i have had succes. I only use my Mac Pro 2.66GHz to run Windows Vista. You have to make sure that the System is configured to boot straight into Windows, otherwise the GFX card/Display will NOT work. thx SL Link to comment Share on other sites More sharing options...
mtotho Posted January 26, 2008 Share Posted January 26, 2008 LOL Do no buy AlienWare. Alien ware is owned by dell.. and is definately worse than dell. Alien ware is most overpriced. I recommend building ur own or Buy a Dell. Or check out ibuypower.com Link to comment Share on other sites More sharing options...
Listed1st.com Posted March 20, 2008 Share Posted March 20, 2008 Just wanted to chime in my 2 cents... I too went 8800 in my Mac Pro when it came out, I simply used a molex to 6-pin VGA adapter and ran the wires down.... Mine was an 8800GT. One thing I recently learned when I dove into building a Mac Pro from prototype parts is the molex power that the CD roms use is fed off the logic Board, not directly into the power supply! So the very early post about buying the power adapter to get power from the logic board is well worth while, I wouldn't suggest running a GTX off the molex! In case anyone was wondering :-) And I must say, I kinda think the Mac Pro Prototype Logic Board is a cool colour! Link to comment Share on other sites More sharing options...
