A note of caution on the 470 cards in a single gfx card system –

Most of the time, it works fine. However it is running the UI and cuda from the same memory, which in some instances gets filled up. Then you get crashes or a crashed render.

Best case is to still run a dedicated UI card.

re-read through the manual, no details to help.

Good post, thanks Mikhail.

Nicely done! Thanks for the tip, and for explaining it so well.

My suspicion is that you’re only using the 1 card.
The memory gets filled up running the UI and splitting the instuctions against the cuda based processing. I get that error message on some projects with my 470 when I load large tiffs into the timeline.

First make sure youve installed the packages in the 10.6.8 package above, then try running with a 2nd card.
You will probably need to build an efi string instead of graphicsenabler to do that though.

really? 3 channel mattes!? Very cool! Can you explain the mechanics of that? In other words if I load a material ID pass from another software that has RED, GREEN, BLUE, YELLOW, MAGENTA, CYAN, can I simply key those to generate alphas?

Or does it have a mechanism which separates out the RGB into locked channels?

Are you using the ApplegraphicsPowerManagement.kext? It was probably re-installed with the update. try removing it.

I assume you’re booting with the non-480 card as the primary display?

Also are you running to the DVI port closest to the motherboard?

Also are you definitely getting OpenCl accelleration? (Is your top menu bar translucent?)

How are you initializing the cards? EFI? enabler kext? (If so which one?) I’d switch to an EFI string in your boot.plist.

Also I believe your P6 deluxe will behave different than the p6t7 when using EFI strings, as the extra n100 chip for the extra x16 slots complicates your pci bus paths. Make sure you’re not trying to run the same thing for both systems.

All in all, these are the reasons I don’t run hackintoshes anymore. Even with the 470 on a 2011 mac pro, I still have that nagging doubt in the back of my head when something goes wrong. Not worth the stress anymore.

Here’s my list of caveats:

– don’t upgrade if using Phantom .cine files in your project. (Different debayer, your grade will change)
– export your current project before updating (file, export)
– backup your database

Pretty simple..

Import an XML of media
– greenscreen on v2, background plate on v1.

On the GS layer, add a few parallel nodes.
– Top will be grade for GS,
– middle will be spill suppress layer
– bottom will be base for alpha key

Right click in node graph to add an alpha output
– little rectangle appears on right of node graph

Create a matte from the greenscreen
– pull greenscreen on your bottom node,
– combine alphas of multiple nodes if necessary
– map matte output of those nodes to alpha output

Remove green spill as necessary
– on the middle node, pull a very liberal key on the greenscreen
– use the curves – saturation tool to correct for spill

You now have your plates comp’d color grade them to match accordingly.
The key doesn’t do as well with hair, but for my shots it was fine. Of course you could simply use this technique as a temporary way to grade the plates and foreground, and still do your final comp as an effect.

here’s the result of my shots..
