You need to have the Quadro drivers for 10.6.8 as a supplementary install. This is not the same as CUDA drivers, they are a separate thing.

Nvidia has some specifically for 10.6.8.

If they won’t install, you can right click the installer and find the 3 components and install them individually.

Only 1 display working on Q4000 is standard sign that not running right drivers.

Lion has the Quadro drivers already built in, but SL they are always separate.

If you have a Cubix expander and have at least one 8 pin PCIE power plug, you should go for a GTX480 instead of 470.

There have been tests done by a known independent 3rd party with 7.1.2 that showed the GTX480 to be embarrassingly faster than a Q4000. These results were shared with some people at BMD but will likely never see the light of day beyond there. The realities of sustainable product support and advertising dollar flow will see to it. Just how it is.

If there is someone in Hollywood who would like to set up the tests that Sascha Haber posted I will be happy to loan out a GTX285, GTX470, and GTX480 for comparison. (I recently sold my Q4000, but we will need to include it…best if whoever does testing already has one) Same machine, same files, same tests, same GT120 for GUI. Only the GPU will change. This would need to be a Mac Pro, preferably with a Cubix expander but if not I can bring a PSU for the GTX480.

I think this is the only way to get REAL numbers out there that have not been influenced by advertising revenue and “give us a good review or no more test units” type threats. This will need to be a person or persons with some technical skills. I would like to just loan out the cards and perhaps some AGPM kexts but have no other input.

Good news.

I am from MacVidCards

We have just put together a GT120 & GTX285 combo for 1,1 and 2,1 Mac Pros.

Initial tests indicate Resolve runs on these machines with these cards.

Obviously not as fast as the later Mac Pros, but if you don’t have the $$$ for a new Mac Pro, why not get started on the one you have?

In the name of accuracy, the trouble with these cards on 1,1 and 2,1 machines never had anything to do with PCIE 1.0 vs 2.0, the issue was that the original Mac iterations of these cards were EFI64 and the early Mac Pros were EFI32. I wrote an EFI32 ROM for the GT120 (Dual DVI version) that allows use of GTX285 via a small piece of software from my friend Netkas.

I will be happy to loan a set of these cards to a responsible & recognized party in Hollywood area to verify that this works. Just sold a set to a guy who will be posting at Reduser shortly.

I am also the guy behind the Mac Pro GTX470 and GTX480. (These have been benchmarked by a known benchmarking site, the GTX480 left Quadro 4000 for dead using Resolve)

So, Resolve running on ALL Mac Pros…can’t be a bad thing, right?
