media composer 6 will no longer mount my AMA volumes even though 5.5.3 would


using a geforce as a quadro


Mind you, this is not for the feint of heart, has no guarantees, is not tested fully and I take no responsibility if it fails…. But while trying to find how much avid depends on the quadro card for its speed and use of GPU assisted renders I ran into an interesting post which allows you to force the avid to acknowledge the Geforce card as fit to use for GPU enhanced computing. And it goes like this:

First you download GPU-Z, a program that tells you what videocard you have, what driver it uses and how hard it is working. You can find it here:

Install, open and get the following information:

under the name header, the name of your GPU, in my case NVIDIA GeForce GTX 580

under the driver version header, the version of your driver, in my case 275.33

Then you go to the file avid uses to determine which cards are approved and which aren't, most probably located in c:\Program Files (x86)\Avid\Avid Media Composer\SupportingFiles\Config. It is a text document called QualifiedGpuBoards. Open it in notepad and save as QualifiedGpuBoardsOriginal. Just in case it doesn't work, you can go back to the original. Close notepad and open QualifiedGpuBoards again.

You now will see something like this:

;This file contains the list of qualified GPU cards for both MAC & PC.




; – April 29 2008: UDevC00098019: Remove 4600 & 5600 from the list and leave only the 3700 for now.

; – Sept. 10 2008: UDevC00111492: Add driver version qualification (169.47).



;NOTE: Qualified board must be described as: "Full_name : Vendor_name : Model_number : Driver_version".

;For Quadro FX, the preferred driver is 190.38.

;For Quadro, the driver is 259.77.

;A few people have been hit by a 190.38 driver crash on Win7/Vista with FX3800/FX4800. If this happens, use 259.57

I said like this, because this is the already modded file I now use. In the last line I deleted the Quadro 2000 information and replaced it with the info retrieved from GPU-z following the format used in the other lines, which is also described in the notes of the text. Do the same for your card and save. If all goes well avid will start and mention your card briefly during startup as acknowledged for use. And when rendering certain effects GPU-z shows that the video card is used for calculations with an increase in GPU load.

Now as said all of this is at your own risk, and I will test further. But if anyone wants to try please post your experiences. 

Good luck, happy editing and many thanks to Gonzakpo for finding the way and Wokis for daring to try it (don't know the real names)
