sadly the 8800GT is last one from Nvidia that works natively
the quadro 4000 isn’t going to work well at all
we have kits for 1st Gen machines but ultimately you would be happier with 2008 or later Mac Pro. (2009+ even better)
-
drivers in the OS no good
Nvidia has newer ones for 10.6.8 on their site
also, you need CUDA drivers from them but they are separate things
-
Try them both individually and test with CUDA-Z.
If GT120 has issue by itself, it’s bad.
If it works fine, problem lies elsewhere
-
which OS & machine?
what slots?
-
From those CUDA-Z numbers it also app[ears that you have the 470 in a 4x slot.
Host to Device will be around 5000 when in a 16x slot
The Single Precision Float number is the one that seems to predict Resolve performance.
When the kext is properly deleted or edited, that number should be 1080 or so with a 470.
A GTX285 1 Gig card will achieve around 700.
A GTX480 at full speed will hit 1300-1400.
And a Quadro 4000 usually gets around 450 or so.
BTW, we now have a GTX285 that only requires a single power cable. It is NOT as fast as a regular GTX285 as it is down clocked, but it IS faster than a Quadro 4000. It is a double width card, but only having a single power connection means it can work with either a Quadro 4000 or a AMD 5770 with no splitters, adapters or other buggery trickery.
It scores around 500 in the single precision float, so a hair faster than a Quadro 4000.
But everyone with a GTX470 or GTX480 will need to realize that each OS update will probably include a new AGPM kext. FWIW, I believe that the GTX470 still uses it’s own planned power management when this kext is deleted. You can verify this with the OpenGL View test. When you first run the test the numbers will be in the hundreds, after a second or two the drivers register the additional load and kick the card into high gear, you will see the number LEAP into the thousands. If you re-run the test right away they will start in thousands again. But if you leave the machine idle for a few minutes, the score will start in hundreds again. So I am 99% certain that the 470 is just fine without that kext.
The odd thing about the AGPM kext is that it only has 2 @ Nvidia cards defined, the GT120 and a GTX260. (device ids of 0640 and 05e2) This is odd because Apple never shipped or offered a GTX260 and yet the GTX285 which uses device id of 05e3 runs fine.
The reason I include instructions for changing the “05e2′ entry into whatever the 2nd card is is so that the 0640 entry stays and the GT120 remains. I am not certain that it is important but since adding it properly does make it run the card, it doesn’t seem to hurt.

He would have had same files as you.
I suspect that you were sent the wrong GT120.
Please email or pm me an address to send you a replacemet.
For now, try just the GTX285. There will be no boot screen but card should show up once desktop reached.
-
Try running CUDA-Z to see what the throughput of the cards is.
You can also connect a display to them and run OpenGl View test.
It will show if they are being throttled.

Since I have been unable to make the GF100 EFI work on these GF110 cards, they can currently only be run using Netkas’ ATY_Init. This means no boot screens and that the cards will require adding the device id to the GF100 kext and they will most likely run at 2.5GT/s .
They won’t ever work in 10.6.8.
They will likely require the device id added in with every OS update, unless Apple/Nvidia decides to start including them.
IN my experience, they require adding their device id also to the AGPM kext. (with GF100 cards you can just throw it out).
I will try again and may eventually figure them out but for 10% more speed, they are currently quite a bit more bother.
-
That is the audio part of Quadro 4000 for which nobody has provided a driver.
Completely normal.

Jonathon Lee,
Could you elaborate on what cards you were powering and what happened?
Also how many drives and other cards you were using?
I think it would be very helpful to many people to know how much is “too much”
