Cubix trouble
Hi,
we are experiencing a rather cumbersome issue with our Cubix Desktop Xpander Elite. Our setup is as following:
inside the GPU-xpander we have 3 GTX Titans in slot 1, 2 and 3. Slot 4 is empty. The GPU-xpander is connected to a MacPro 5,1 6-Core Intel Xeon. Inside the Mac we have a GTX570 on slot1, the GPU-xpander-PCI-card on slot2, a Blackmagic decklink card on slot3 and a 10gbE-card in slot4.Until today everything worked fine – all relevant applications showed all 3 GTX Titans well. Today editing on the machine in FCP7 was very strange – we experienced several hiccups in audio and several crashes. We did a system update to 10.9.2 and updated the decklink driver which didn’t help. So I made a quick look inside system profiler and found that only two GTX Titans showed up. I suspected that maybe one of the Titans was damaged so I unplugged all of them and tried them one by one. Each time shutting down the mac, changing cards, booting up, checking in system profiler.
I found out that it couldn’t be one of the cards because every card worked in some combination. I just couldn’t get three cards to work, though.

System Profiler shows one cardTitan 1 and Titan 2 / Slot 2 and Slot 3
System Profiler shows one cardTitan 1 and Titan 2 / Slot 1 and Slot 3
System Profiler shows one cardTitan 1 and Titan 2 / Slot 1 and Slot 2
System Profiler shows one cardIt’s also quite strange that as soon as any GTX Titan is plugged into the Cubix, System Profiler show „There was an error while gathering PCI card information“ in the PCI cards tab. When all GTX Titans are removed, or if I disconnect the Cubix from the mac, System Profiler shows all connected PCI cards fine.
I assume the Cubix or the corresponding PCI-card has some issue.
Please help, as we are in the middle of a grading job and we rely on our gpu performance.Best,
