TitanZ has PLX onboard for splitting/multiplying lanes - that might be a point of problems why this card doesn't work..but it's just a though & anything I could base on facts.
I found this:

I will give it a try
Thanks Man!
That's my setup in the link!
I could be wrong about what fixed it but I did run into the same thing at first.
The stock Apple drivers actually do run most Nvidia cards, and I think that includes 780s and regular Titans. But, the Titan Z does require that the Nvidia Webdrivers are running and if they aren't and the kext files have been edited to allow tunneling through thunderbolt, the system crashes when the card fires up. If the system boots without the webdrivers running, my comp would crash when I opened Octane. I ended up updating to Yosemite so I could run the latest Nvidia drivers. They might run on Mavericks but I wanted to update anyhow to get it over with. Ever since, everything loads fine.
It could possibly be a power issue? But I think I saw that you are using a powered riser, correct? If so, I think that eliminates the power issue possibility.
This is how my Titan Z loads into System report. Does yours look like this?
!!!Up And Running!!!
