Problem was, I already have the 5.1, with the same specs as you. My GPU, the GTX 780, is not made for the Mac Pro because it takes more power than the internal supply can adequately provide. Like Sascha said early in this thread, my capacitors were getting overloaded and if I kept it up the circuits would have fried. The crashing was my computer begging me to stop the torture. It was definitely time to freak out, since I have two clients who are breathing down my neck. I don’t have time to do anything but lock in on the solution, which Clark was kind enough to figure out & provide.

I can only imagine how much more fun you’re having with the 5.1 Mac Pro. I jumped from a 2004 MacBook Pro running Apple Color to my tower and Resolve–what a wonderful experience it was the first time I did a project on my new system.

[Jesse Glucksman]

Bingo. You’re my hero.

One staple and some electrical tape later, and everything appears to be running just fine (at least as well as 4k footage with only one shared GUI/GPU can run).

Again, thank you.

Hi, Clark. A question about the Corsair you used for your chassis. I got a Corsair today–the 650, since I only need it for the GPU. Yes, 650 is a bit overkill, but worth it for the peace of mind. Except…it appears to not work. Plugged in & turned on, there are no LEDs or hums or anything to indicate it’s functioning. Further, while the 780 turns on with my computer, I am not getting a video signal to my monitor. Also, the 780 stays on when I unplug the Corsair, leading me to believe it’s getting just enough power from the PCI connection to be on but not enough to actually be used for anything (including further destroying my computer, for which I’m grateful).

What’s your experience with your Corsair? Does it have any lights or hums or anything to indicate it’s alive, even if the chassis itself is off or unconnected? I’ll call Corsair’s tech support first thing in the morning, but if you happen to still be up and in a charitable mood, I’d love to know your thoughts on this…

[Jesse Glucksman]

First of all–THANK YOU both for the advice & guidance, Sascha for helping narrow me down to what the problem is and Clark for the detailed information on how to find a workaround. I put my 5770 back in and my computer is running just fine, so it looks like I managed to avoid fully killing my computer. It was still in a “Take a freaking hint, dude, before you ruin me for good” mode.

The problem I have now (albeit one that’s temporary, but thoroughly inconvenient): Resolve won’t open with the 5770. “No CUDA Acceleration Hardware Detected.”
I know v10 stepped up in power so some older GPUs are no longer supported, but it’s hard to imagine that the stock GPU that comes with the old-style MacPros would be among them. Do you guys know a way around this, or am I stuck until I can get a supplementary power supply & plug the 780 back in?

[Jesse Glucksman]

Thanks for all that information. I’m going to plug back in my old Radeon 5770 tonight. If my computer isn’t irretrievably gone, I’ll absolutely get the extra power supply. If it is…well. I’ll cross that bridge when I come to it.

[Jesse Glucksman]

Is there’s solution other than a new computer? You’re freaking me out. If I put in a different card?

[Jesse Glucksman]

I did the uninstall/reinstall but no change.

By prefpane do you mean the Blackmagic Design page in my System Preferences? I don’t see anything that specifically says the card is detected, but there are no warnings, and I’m getting video when I open a project in Final Cut.

[Jesse Glucksman]

Ok, so I reinstalled 10 and the project translated over so I appear to be up & running, and the 23.976fps footage/24fps FCP XML is now the only issue. Fun times ahead.

[Jesse Glucksman]

Hi, Peter. Sorry for the delay and thank you for your offer to help.

Here is a link to the XML: 6782_cbforcolor.xml.zip

I just got the project up & running in v9.1.6, and the only thing I did differently was to import all the footage into the media pool before importing the XML. The footage is Sony RAW F55, MFX files, plus a bit of h.264 from a Canon DSLR. Is it that simple, or is there something off with 10?

No multicam clips. Some shots with speed ramps, but those will have VFX and will be delivered back to me later. Nothing fancy as far as I know.

Possibly complicating matters is that the raw footage is 23.976 but the transcodes and FCP sequence were 24.

Again, thank you.

[Jesse Glucksman]

FCP 7, a feature-length project. I unchecked all the “automatically import to media pool” and whatnot options.
