    I have a mid-2012 Mac Pro running a Cubix GPU expander. My main purpose is for Da Vinci Resolve Color Correction.

    I have upgraded to OSX 10.9.4 Mavericks and installed the following drivers:

    CUDA Driver : 6.0.51
    GPU Driver Version" 8.27.26 (334.01.02f02)

    I have power to the Titans via both power ports on each card as they require a decent amount and they are lit up and fans spinning.

    When I install Da Vinci 11, I get the CUDA not detected Error. I have the Web driver selected in the upper right hand screen.

    Any thoughts on how to make Da Vinci utilize the Titan Blacks?

    Thanks ahead of time.

    I don't have Titan Blacks (TBs) and I don't have a Cubix. That said if no one else can help you to get your TBs working in the Cubix, try running up to two of them in your Mac Pro using a FSP Booster (to help power them) and run your other cards in the Cubix. You're not the first one having issues with the Mavericks + Cubix + Titans. Just search "Cubix" in this forum; see,e.g., .

    PS - Without any other PCI-e cards, a pre-2013 MacPro can run three Titans (excepting the Z) using the FSP Booster for additional power support, with a number of compromises to hard drive placement.
