Decklink and Kona in same Mac Pro — YES IT WORKS — If you’ve been wondering read on…
I replied to a thread below that posed this question with some initial testing I’d done with a Mac Pro, Decklink Extreme 3D, a Kona 3 and a Cubix expander. You can read that to see one possible configuration. Today, I’ve discovered some more options that those of you interested in a dual boot scenario (boot one partition with BMD drivers for the Decklink card, and boot another partition with Kona drivers for Kona 3) may find useful.
CAVEAT – these are initial findings and have not gone through the “torture test” of long hours with clients in the room. Basic functionality with Avid, FCP7, After Effects and Resolve has been done and everything plays and renders as it should. That said, proceed at your own risk. Also note that I’m not using the additional HDMI out backplane on the Decklink.
First, the simplest configuration requires no Cubix. Put the Decklink in slot 3 of the Mac Pro and the Kona in slot 4. As long as you boot to the partition with the appropriate drivers there seems to be no problem. Slot 1 is of course occupied by GPU and slot 2 COULD theoretically be used for storage (fibre, eSATA, whatever) but I didn’t specifically test that.
Second, if you want a more beefy Resolve system with multiple GPUs etc, you’ll need a Cubix Xpander. I’m using the Desktop Xpander 4. The following configuration allows me to boot into a partition with AJA drivers to work with everything BUT Resolve and to restart into a BMD partition to work specifically WITH Resolve:
Mac Pro:
Slot1-Quadro 4000
Slot2-Cubix interconnect card
Slot3-Decklink Extreme 3D
Slot4-emptyCubix Xpander 4:
Slot1-Kona 3
Slot2-Atto Celerity FC42-ES
Slot3-NVidia GTX690
Slot4-EmptyOne configuration that specifically did NOT work for some reason was putting the Quadro 4000 in the Cubix and using an ATI 6770 as the display GPU. This arrangement would cause the Kona card to disappear but didn’t seem to affect anything else. Due to other arrangements that I tried, I believe that particular conflict was between the Quadro and the AJA as positioned in the Cubix and had nothing to do with the ATI. This arrangement does remove the Quadro from the cuda cores that Resolve can use for rendering, but DOES make it available for After Effects and Smoke. With the GTX690 handling the processing for Resolve, this is probably a decent trade off.
So, there it is. This CAN be done. Your mileage may vary and I’d love to know if any of you get other configurations working well. If this whole thing goes up in smoke in the next few days I’ll let you know, but so far so good.
