Quadro 4000 Mac Not Working

Jan 2, 2012 8:29 PM

Hi all,


I have just purchased a Quadro 4000 Mac for the following system:



Model Name:     Mac Pro

Model Identifier:     MacPro3,1

Processor Name:     Quad-Core Intel Xeon

Processor Speed:     2.8 GHz

Number of Processors:     2

Total Number of Cores:     8

L2 Cache (per Processor):     12 MB

Memory:     16 GB

Bus Speed:     1.6 GHz


System Version:     Mac OS X 10.7.2 (11C74)


Have just done a clean install of Lion and the latest CUDA driver (see screen shot) but the card is not being recognised properly. System profiler returns the following information on the Video Card and nothing else:


Screen Shot 2012-01-03 at 10.13.18 AM.png


Type:     GPU

Bus:     PCIe

Slot:     Slot-2

PCIe Lane Width:     x1

Vendor:     NVIDIA (0x10de)

Device ID:     0x06dd

Revision ID:     0x00a3


The card itself has a green light powering up okay and judging by the above information is being recognised in PCI slot yet there is no signal coming out of the card whatsoever.


Is this a fault with the card or a driver issue?


Any help will be much appreciated.
