    After checking the Titan Rom, find that there are EFI part in it.
    Does anyone try put the card in mac pro 2008 or later (Mac Pro 2009 or 2010)?
    See what will happen ?
    Thanks for reply.

    ^gop?

    Also, can't wait to see someone do this, or see apple do this when they refresh the mac pro.

    Google "GOP" vs "UGA"

    I'm going to do a post here soon.

    I posted a few weeks ago about this at Netkas. Nvidia and AMD are selling UEFI cards now.

    But they don't work in Macs.

    It would be interesting if it could somehow be tested on GOP Macs. Apple has been moving to GOP, but the Mac Pro still hasn't.

    Here's to hoping that it makes the move next version. Seems like a no brainer.

    At this point would require booting from GPU card from Thunderbolt enclosure. Makes for an expensive experiment at the moment. (and doesn't really solve the problem of hot-plug requirements from the Graphics drivers needed by TB. )

    Moving since around 2008 which is likely the last time the EFI firmware was likely significantly tweaked for the Mac Pro.

    Transitioning to Xeon E5's in 2012 was also a no brainer (with proper planning).

    But yes this should have been the first significant R&D work on a motherboard since that time period. That's more than ample motivation to upgrade the firmware.

    What about the power requirements? Second PSU required or would an 8 to 6 pin adapter be safe with this GPU at 100% load?

    Edit: Answered my question after checking some reviews. Looks like the card pulls 250 to 270 watts under load, and in every case required significantly more than the 680 and 580. And no, those are not system loads, but are apparently pretty good efforts to sift out other variables and get an accurate bead on the GPU power consumption. Titans pull every watt of the rated 250 when pushed to the max. With all the talk of burning up mobo components it doesn't look like it would be safe at all without additional power.

    titan pulls 250 watts, from early 2009 mac pro, max load on a single pci is 300 watts, so no problem.

    Don't think that is right. 300 is total load from all four slots at 75 per with the other 150 coming from the two six pins. At least that is what numerous people have posted on other threads when trying to use 580's and 680's or other cards with one or more 8 pin connectors.

    See sections 5 and 22 in the first post here:

    Specs from manufacturers are almost always suspect. A couple of reasonably knowledgeable reviewers are calculating peak loads in excess of 250W. Twenty-five over the 225 limit is bad enough, but double that and hit 270 to 275 at 100%? Forget about it. The risk is too great. I think it was MVC and one or two other GPU gurus who wrote somewhere that the only safe way was to power such a card solely from an external PSU. That's good enough for me to refrain from any experimentation.
