Can’t get GTX 580 to display on my Mac Pro 2,1
OK…here’s the scoop, I’ve read many posts circling around my needs so I thought I’d get some feedback about my issues:
I have a 2,1 mac pro and I’ve read guys making the gtx 580 work with it. I’ve installed the latest quadro4000 nvidia driver 270.00.00f06 as well as the latest CUDA driver. (note: I get a window that comes up when installing that says something not being support some kext file, I think it was PACEsupport.kext, cant be sure.
I have both the 6 and 8 pin cables plugged into my motherboard, but I seem to be reading that I need an additional power supply, possibly the Booster X5 or other.In conclusion, I’ve tried various DVI, VGA, HDMI cables to my monitors and no displays ever.
Can anyone help me problem solve this. I know it’ll work!
Some say just go with the 570 or 640 and I dont have to worry about additional power, but it’d be nice to just get this going.thanks y’all

I have this unit running on a 5,1 Mac Pro. I wonder if your problem is that it won’t run with a 2,1 Mac Pro but I don’t know. However, assuming it will, I use a Coolermaster 850w external PC power supply. The card needs three power connectors and draws 650w at full tilt This is twice what the current Mac Pros can supply. In addition, all external power supplies designed for PCs need their power supplies ‘turned on’ by the PC even after you are supplying mains power. This involves shorting out two pins on the Motherboard socket hanging out of the PS (which of course you would not plug into anything). There is a floating plug you can purchase which will do this – it’s used for testing P. Supplies out of the PC and sold as such. So having connected this plug you power up the supply and then power up the Mac – works a treat. PPro & AE run like magic as long as you have lots of Ram – I use 48Gbs.
I hope this helps.I used to be Jon Hiseman but I’m feeling better now.

I’m not sure what your 3rd power connection consists of. my GTX 580 only needs 2 connections, a 6pin and an 8pin. thats it. not sure if we’re talking about the same card.
thanks for your thoughts though

My GTX580 has 2 x 8 pin power sockets and 1 x 6 pin. I bought it from Macvidcards in LA. It has been reprogrammed with a special EFI ROM to work with the mac pro.
Just an afterthought – This card is not recognised by Pro/AE unless you add it to the supported cards list.
To Add a Card for Premier Pro and AE right click the App and select show package contents.
Modify Contents/cuda_supported_cards.txt for Premier Pro and raytracer_supported_cards.txt for AEI used to be Jon Hiseman but I’m feeling better now.
