Gtx470, a driver, cuda and OS
Hi there,
A few days ago I built a machine to run a resolve grading suite, it’s a macro 4,1 8core 2.26Ghz, 24gb ram, BM 3d+, 16TB eSata (4x4TB g-raid es), euphonics mc color, gt120 and gtx470.
My issue is about the performance of resolve. My OSX is 10.6.8 , my cuda driver is 4.0.50 ( resolve does not give me any error) and I’ve loaded the latest q4000 driver. All is working well but… I do not get the speed that I was hoping for, actually I get better speed with apple color on the same machine (on the gt120). In resolve I get on a prores4444 1080p with 3corrector nodes about 4-8fps….
Does anyone get to utilize the full cuda core potential of the 470? Is it the Cuda driver (tried 3.2.17 and 4 but to no avail) or maybe the OS? Is running 10.7 works better?
I was really exited to run resolve on this configuration but now I’m a bit sceptic about resolve on mac.
Thanks

I have the heard that the cuda drivers are now automatically integrated in Lion (OSX 10.7).
There is a listing on ebay somewhere for GTX 470, which explains this in the description….just found it:
“You will need to download the Quadro 4000 drivers from the Nvidia website. You will also need to remove “AppleGraphicsPowerManagement.kext” from your Extensions folder. (S/L/E) You can choose to modify and reinstall this kext or just leave it out of the folder, otherwise it will throttle the card down to low speeds.
With a SPECIAL EFI ROM by renowned Mac Guru, The Rominator with additional help from the Master of Mac Mods, Netkas….
Tested & working in Mac OS X Lion 10.7 GM (11A511) , no need for drivers, now included in OS. Just need to remove the AGPM kext !!!”
Hope that helps…

The above post should cover you. Otherwise:
Obviously make sure you’re using the 120 as the GUI card.
Make sure your system actually sees both cards. (Your galaxies benchmark scores should be 50+ and 300+) If not, how are you initializing the cards? A kext or an EFI string in boot.plist? (Or in bootloader efi?) -
I’m curious about this setup. If you wanted to use the 470 for AE or Color could you just plug your monitors into that card instead of the GT 120? Would this be necessary to take advantage of it in these programs?

It would speed em up factor 12 when using any CUDA, yes.-
Its 1100 Gflops compared to 90 on the GT120 🙂But I agree, running Lion makes it easier.
What i did is copying all the Lion kexts into Snow, that totally fixed it.Go there to get a proper CUDA test app :
https://sourceforge.net/projects/cuda-z/files/cuda-z/Beta/
It tests all cards found in the system and displays their performance.A slice of color…

Thanks guys,
Will try all of the above this morning and i’ll tell you if it worked
Many hanks

BTW, don’t know regarding the adobe software to be connected to the 470 but i’m sure it will work.

Hi again,
Thank you all, you guys are great!
Success, resolve is flying now, 14 different nodes and still plays 25fps and sound with out a problem !!!!
I did some test before removing the AppleGraphicsPowerManagement.kext file, the result from Cuda-Z (Thank you very much) were:

May I ask how are you initializing the 470 in OS X? Is it an EFI version?
-
Yes, its the one you can buy on ebay.
Not the standard one.
Still, we are talking a 350 bucks investment here compared to 800 for the Q4000 with more than double the performance.
No-brainer.A slice of color…

Has anyone tried the GTX 480? from macvidcards;
I’m guessing the extra power/noise/heat isn’t worth the tiny performance bump from the 470s….but I’d still like to know if these work! (for use in Cubix where power is less of an issue)

Ive asked this too on a diff post.
The ebay version is a 480 whilst everyone talks about the 470.
Need confirmation as to the diffs.
