Cyclon PCI epander with quadro 4000 problem

[Dwaine Maggart]

I’ll just comment that with the Cubix expansion chassis, and Q4000 card(s), OS X can not enumerate the Q4000 PCI data in the PCI Cards section of the Mac System Profiler. Perhaps the Cyclone expander has a similar issue. Perhaps all PCI expanders have this issue?

Thank you Dwaine,

I know at least I’m not crazy.

My concern is that the fact expander cannot enumerate PCI data with quadro 4000 is the sign that 4000+expander may be cause of more problems (like mine with red rocket and usb dongle)

Now that I have removed 4000 and put GTX 285 instead, I have no more problems…

Stange…Maybe Lion OS will solve this

I’m using a Cyclone Gen 2 expansion chassis, and have not experienced any problems that I think come from the Expander. I built my workstation per the Resolve configuration manual. So…

Slot1 Quadro 4000
Slot2 HBA
Slot3 3D connector from DeckLink
Slot4 DeckLink HD Extreme 3D

In the Cyclone I’ve been using the GT 120 and an ATI 4870.

As for System Profiler not recognizing the the expander, on my system, System Profiler under PCI Cards recognizes the expander as a pci-bridge, and shows the various cards in the expander.When you put the GTX285 in the system does System Profiler identify correctly?

The only problem I’ve had is with the 4000, not the Cyclone. With the 4000 in the system I generate kernal panics when trying to boot from a CD (such as the OSX CD). PNY is looking into this for me. When I spoke with Nvidia’s tech support they told me the 4000 & GT120 wouldn’t work together, nor would a system using an ATI product, but in his opinion multiple 4000’s was the only correct configuration. Hmmm?

Correct me if I’m wrong, but I’m assuming you’re using one of Cyclone’s Gen 2 expanders? OS 10.6.7?
And have you tried putting one of the 4000’s in slot one as suggested in the config manual?

Hi Michael,

When I put the quadro in the mac, I don’t have any problem.
It’s when I put the quadro in the expander that the issue appears…

I have 3 quadro 4000 so I hav to put the 3 in the cyclon. My system is 10.6.6.

Idon’t know if it’s recommended by davinci to upgrade ?

The Q4000 has some problems I.M.H.O., and upgrading to 10.6.7 makes downloading the latest Cuda & 4000 drivers essential from my experience. I haven’t had any problems with either DaVinci or the 4000 (except for what I mentioned previously) after upgrading to 10.6.7 and Nvidias latest drivers.

I would try putting one 4000 in slot1 of your MacPro, and the other two in the expander’s slots 1 & 2.

Which expander did you get? Is it the 2710 with eight double wides? Or the 2707?

P.S. I just spoke with Dwaine at BlackMagic and he says they’ve upgraded their system to 10.6.7, AND UPDATED the NVIDIA drivers. After that they have had no problems.
