NEVER MIND – HOLD IT – DON’T ANSWER. The power supply for the display got unplugged in the shuffle. Let me give this another try …

The power from the Superdrive works fine for the Q4000; however, only the Displayport side of the Q4000 seems to be working – the DVI side of the output isn’t live. Is this a setting in Sys Prefs someplace? Not Displays, because that’s showing me two Displays in the correct configuration. Its just that one is black: no power indicator, no USB/Firewire passthrough.

Just as a reminder, I’m trying to run the displays off the Q4000, reserving the GTX470 for CUDA processing.

Any ideas?

Thanks!

Wow – very generous reply. Thanks!

I’ll try to find the components tomorrow and see what I can come up with. Thanks again –

OK, that works. BlackMagic says they like Slot 1 for best performance, but that any slot will work. I just figured maybe the performance issues I was having with PP had to do with BMD in that forth slot, but probably it was a slow (GeForce 8800) card for display, which I’m now replacing.

You can pick up a Molex to Y splitter pretty much anyplace? Is that a four-pin on the disk drive side, to two-four-pins on the Y-side?

So that solves my power issue, certainly. Thanks! However, I think I am still missing a fast slot: if the GTX470 is in Slot 1, the BM Decklink in 2, my SAS array card in 3, that just leaves Slot 4 for the Quadro. That doesn’t work, does it?

Can anybody tell me the precise modification I’m looking for in a “modded GTX470” card?

Thanks!

How do you specify the particular modification? There are a ton of GTX470’s listed, but it’s not clear to me exactly which mod is appropriate.

Thanks again!

Yeah, I was wondering about that! It IS an old card, and seemed counter-intuitive.

But Windows?? Dude, don’t do anything scary or rash. There’s so much to live for! It’s always a new day! Call us before you do ….

I’ll check out the modded GTX 470 – no issues with this modded card from anybody?

Cheers!

Davinci Resolve requires BOTH a graphics card and a dedicated CUDA card, as far asI can tell:

“When using an NVIDIA Quadro 4000 for Mac, as the GPU, install the GPU card in slot 2 and the GUI card in slot 1. The GUI card can be: an ATI Radeon HD 5770, an NVIDIA GeForce GT 120 for Mac or an NVIDIA Quadro 4000 for Mac.”

While I’m not using an HD5770, T120, or a 4000 for GUI, a number of users have reported getting good results with the 8800. I think.

I do note that Davinci also states that the latest driver for CUDA may not be appropriate, and that at present, only 10.6.7 and CUDA 3.2.17 are approved. So that may be something to look into. And I will.

Thanks for the input!

Yep, I’m CS5.5, so that’s not it. I think you’re probably right, that it’s a function of either my particular Blackmagic settings (PsF versus p?) or the BM driver itself needing some improvement. Ah ….
