Quick question for you: how did you manage to fit the 5770 in the top slot 4? My understanding is that the 5770 is a double width gpu. Did you modify the physical bracket connection on the GPU? Or perhaps there is a single width model out there?
There is actually room for the double sized card in slot 4 as long as hard drive 2-4 are also empty. The bracket that hold the PCI cards on place is under the bracket for the slot 4 5770. Therefore it is not tightened in there but as you can see by my results, it does work.
BruceX on FCPX 10.1 and 10.9.1 (ProRes) -- 1 min 31 seconds (or 91 seconds)[/quote]
Just got a brand new 2013 iMac. 32GB Ram, 4GB Video card and the results are:
BruceX on FCPX 10.1 and 10.9.1 (ProRes) ---1 minute 31 seconds (or 91 seconds).
Yes that is right a 2006 MacPro exports at the same speed as a 2013 iMac. I must attribute this to the fact that the MacPro has an ATI GPU, while the iMac has Nvidia. Plus, it appears that BruceX at some point simply becomes a test of GPU power. Because as I showed also when the 2006 MacPro has 2 7550's, it completes BruceX is just 53 seconds.
I can tell you however in real world use the iMac completely outshines the 2006 MacPro.
how can I figure out how many lanes are being used by my 5770? At home I have a 2010 Mac Pro (5,1) and I also use a CalDigit RAID Controller card, so I'm wondering if that means I'm running out of lanes regardless of if I can physically squeeze another ATI Radeon 5770 card into my Mac Pro - what do you guys think?
"Mac Pro (Early 2009), Mac Pro (Mid 2010), and Mac Pro (Mid 2012)
The Mac Pro (Early 2009), Mac Pro (Mid 2010), and Mac Pro (Mid 2012) computers implement PCI Express revision 2.0 for all four slots. Slots 1 and 2 are x16 slots, and slots 3 and 4 are x4 slots. As with the Mac Pro (Early 2008), placing a revision 1 card in a revision 2.0 slot works and results in a revision 1 link."
Also take a look at the DaVinci Resolve configuration guide for multiple GPUs:
thanks t! Very helpful link you sent! It basically shows that 2009 - 2012 Mac Pro has four PCIe slots, and slot1 and 2 are hard set to x16 while slot 3 and 4 are x4. In my 2010 Mac Pro 2.8Ghz quad core, I have my ATI 5770 in slot 1 and my CalDigit RAID Controller card in slot 3. I guess the next step is to see if I can physically place another ATI 5770 in slot 2.
If I am understanding the white paper you kindly shared, I think it is saying that my 5,1 Mac Pro can give 16 lanes to both slot 1 and slot 2? I have a single Aux connection left, (my 5770 is using Aux power #2 and Aux power #1 us still available.
I really appreciate your help - I edit day in and day out but I am not hardware savvy.

All that receive are "Test Failed" results. I think I've stretched the video processing life of this machine just a bit too long. I'm a retired 'still' photographer, Photoshop CS6 runs fine - obviously much different requirements to manage large file size video transcoding.
