    Hello,


    Anyone knows if a Mac Pro will be able to run the Nvidia GTX TITAN Z?.



    Thanks

    Like the 590 was recognised? Both chips?

    The 690 worked but not as a dual...

    It's a single hellaceous chip.

    Just the man i was looking for...

    Would the Z work in slot 3? or would the 2.5 height hinder its prospect of fitting?
    And does Octane recognise it as 2 separate cards?

    I assume you're referring to the air cooled 3-slot covering version and not the 2-slot hydro version. Now eyeballing one of the Z air coolers that I removed to make all of mine hydros and also using a bit of reasoning (if a dually can fit in slot 4 with HD bays 2-4 removed, then a trilly can fit in slot 3 {I know that trilly wasn't a word until just now} (and mine fit in slots 1 & 2, but I didn't want to upgrade my OS at that time) leads me to state: I suspect that it will fit in slot-3, but I'd recommend caution because there're two GPUs to keep cool. But I suspect it'd work with Yosemite and appropriate Nvidia drivers. I also believe that Octane would recognize each of the two GPUs separately as it does with my 590s, 690, and hydro Z running under Windows and as does MVC's Titan Z running under OSX [ http://forums.macrumors.com/attachment.php?attachmentid=527137&d=1422527711 ].

    P.S. But why not water-cool it as I've done, with an external water-cooling system; then, you could put one Titan Z in slot 1 and a second Titan Z in slot 4, giving you slots 2 & 3 for other types of PCIe cards? You know I'll help you do this, Phillip, don't you?

    whoops. i meant slot 4 not 3.
    I currently run another 2 780's on long renders but its become a hassle to remove and install each time I'm finding myself doing this way to often.
    the Z equals the same power as dual 780's
    Ideally id like to start using pcie flash storage so ultimately i would like to have

    Slot 1: flashed 780
    Slot 2: 1tb Mac Blade SSD (new mac pro style)
    Slot 3: Dual SSD card
    Slot 4: Titan Z.

    There is one on ebay at the moment at a good price

    MVC's was eGPU from memory.
    Also I'm actually running 10.9 not a fan of 10.10. Is the Z only compatible with Yosemite>??

    I'm not 100% sure whether it's tied to Yosemite by release date, but even if it wasn't you'd be locked into old drivers because Nvidia ties updates to system OS versions.

    Regarding this latest twist - installation in slot 4: SUPERNERD to the rescue, well sort of. What happened to single slot GPU cards while I was asleep. Over 99% of the single slot GPU cards became dual slot GPU cards because they were made to run faster and faster and thus needed more elaborate cooling systems. So what, well if you want that Z in slot 4, you'd have to water-cool it (giving you a two slot card); but you could also perform (or have performed on your behalf) a surgical removal of one of a pair of video out connectors (this is the hard part - not the cutting itself, but protecting those wires from making contact with each other); then, cut that dual space attachment bracket in half (this is the easy part), to create a one slot warranty-less Titan Z. Who'd be crazy enough to do this? I won't be naming names, but all of you know who you are. I've heard that this takes only about 20 minutes from start-to-finish. Then voila! a one slot warranty-less Titan Z.

    Why stick it in Slot 4? The thing draws 375W, I doubt you're going to be wanting to stick a whole bunch of other cards in there. (I assume it's not actually able to be powered solely via the Mac Pro in most real-world use cases.)

    I have a RM1000 on top of my MP.


    hmmm interesting. This is my only main concern now.

    :( water cooling isn't my thing.

    i Guess i could drop the dual ssd card then.

    And just when I thought we'd be heading to the operating room. Almost every dual slot video card has a single slot card hiding within it. Or you could take it out of the case with this - http://amfeltec.com/splitters-gpu-oriented/?view=list which sell for about $200 and design a support for mounting the card or this - http://amfeltec.com/risers/?view=list ; I don't know how much a 32 bit or other riser costs. These types of solutions are used by bit-coiners { http://www.newegg.com/Product/Produ...1353033&cm_re=bit-coin-_-11-353-033-_-Product }. Just remove your Mac's door; then place it on the bottom tray and mount your GPUs on the ~$35 top rack. You might be able to run 2xTitanZs or 4xTitanXs this route, along with your other cards.

    if i don't have to water cool I'm keen.

    the card is out of warranty anyway

    Yeah we have spoken about this guy on another Thread ...

    Mvc rom rips...
    Doesn't exist on the forum but sells maxwell


    After seeing the octane benches and going through them my personal opionion is 7xx series is best bang for buck for octane and 780 6gb is the king for Mac users imho

    In regards to the Z, ends on ebay in 2 days hopefully I win it!!! Believe the seller is dodge though now the bidding went over my Max then the bid was removed !!!! Hate that ****

    Yes, two months of miserable works for myself and Netkas, minutes to steal by them.

    Karma is coming.

    "Mining is the process of running SHA256 double round hash verification processes in order to validate transactions and provide the requisite security for the public ledger of the bitcoin network. The speed at which you mine is measured in hashes per second.
    The bitcoin network compensates miners for their effort by releasing bitcoin to those who contribute the needed computational power. This comes in the form of both newly issued coin and from the transaction fees included in the transactions you validate when mining. The more computing power you contribute, the greater your share of the reward." [ http://www.bitcoinmining.com ]


    Thus, they use GPUs (video cards) for their compute capabilities to increase their earning potential
    and accordingly use and cherish hacks like these:

    1) http://www.newegg.com/Product/Product.aspx?Item=N82E16811353033
    2) http://amfeltec.com/products/gpu-oriented-cluster/

    Since the means by which someone enhances the speed of or no. of GPUs a computer system can access is beneficial to those who use their GPUs' compute capability to enhance tasks involving rendering stills, animations and videos, I try to keep up with (1) what the miners are doing system-wise (they tend to be creative in harnessing the compute power of GPUs) and (2) what marketers provide for them, even tho' I don't do bitcoin mining.

    Hello,


    I am planning to invest on a Mac Pro 5,1 geared towards video production, 3D animation and post production on CUDA based applications, so, so far which is the most powerful Nvidia graphics card that I can run on the Mac Pro 5,1 model, it doesn't matter if I have to used modded drivers or if is natively supported I have an open budget for it. Nvidia GeForce GTX Titan Z or Nvidia Quadro K6000.



    Thanks.

    Probably a Quadro M6000 based on the new Titan X. I'm sure MVC will have no problem making a rom for it.

    My gear is devoted to video production, 3D animation and post production on CUDA based applications. See my signature, below.

    Short Answer: I'd recommend a Quadro M6000 only if you've got fat pockets and want the least amount of installation issues; otherwise, I'd recommend the GTX Titan X - it's a lot less expensive than the M6000 [~1/5 the cost], it's faster and the install isn't that difficult. If you want the fastest single card performance and don't mind doing moderate to difficult mods, then go for Titan Z but given it's space requirements (its a triple slot card) I'd opt for 2xGTX Titan Xs and add external power souces for them because external power sources will be required for the Titan Z also. To air cool those two GPU processors on the Z required Nvidia to use a much thicker cooler attached to the card; thus, consuming 3 slot spaces. Two GTX Titan Xs (each a single GPU processor) would be faster than one GTX Titan Z (a dual GPU processor card).

    Here's the support for my recommendation:

    You can use OctaneBench Scores [ https://render.otoy.com/octanebench/results.php ] to test or research CUDA performance in Octane Render. For example,

    Quadro K6000 score = 82 on OctaneBench;
    Quadro M6000 score avg. (so far more tests done with it) = 124 ;
    124 / 82 = 1.51219512195122 or ~1.5x faster at rendering
    Therefore, Quadro M6000 renders 1.5 times faster than Quadro K6000; but

    GTX Titan X scores avg. = 135 on OctaneBench - ;

    Quadro M6000 scores avg. = 124 on OctaneBench;

    135 / 124 = 1.08870967741935 times faster at rendering

    Therefore, GTX Titan X renders about 1.08 times faster than Quadro M6000 and
    135 / 82 = 1.64634146341463
    GTX Titan X renders about 1.64 times faster than Quadro K6000.

    Quadro M6000's specs are a close match for the GTX Titan X's specs, but generally GTX line is faster.

    Therefore, GTX Titan X is currently the fastest (single GPU processor) CUDA rendering card on market.

    But GTX Titan Z (dual GPU processors on one card) has avg. score of 184 (on air its a 3-slot card; on water its a 2-slot card; in the hands of a crazy like me - it {or any other dual slot water cooled card} might be a one slot card after my Dremel tool does it's thing). But back to what you asked -

    184 / 135 = 1.36; so 1xGTX Titan Z renders 1.36 times faster than a GTX Titan X and
    184 / 82 = 2.24390243902439 or a Titan Z renders ~2.25x faster than a Quadro K6000.

    So, a Titan Z (dual GPU processors) is the fastest single card on the market, if you can find one. I've got 6xGTX Titan Z's on water, split across 2 systems, but right now my Tyan Server w/8xGTX 780 TI ACX SC OC has the highest OctaneBench score - See my signature below or just go to the OctaneBench results site - https://render.otoy.com/octanebench/results.php . You can download OctaneBench here: https://render.otoy.com/octanebench/ .

    However, you used these critical conditions "most powerful Nvidia graphics card that I can run on the Mac Pro 5,1," The easiest one to get going is the Quadro M6000, but it's the most expensive one, requires Yosemite OS, takes 2 slots (I recommend that you ask Nvidia re drivers) and has just one 8-pin GPU power connector; so it doesn't require using an additional power source You can feed it from a "Y" PCIe cable feed from the 2-6-pin power connectors on the MP5,1 motherboard --- that takes only a few minutes to install. Next would be the GTX Titan X (it too requires Yosemite OS) because it's only differences from the M6000 is that the faster GTX Titan X has an additional 6-pin GPU power connector - you can feed that additional power connector by tapping the SATA power cable twice with a "Y" Cable ( 2xSATA male to 1xPCIe 6-pin male) to get the additional power --- that takes only a few minutes to install. The Titan Z requires another power supply - its TDP is 375 watts. FYI - the PCIe motherboard slot supplies 75 watts; a 6-pin PCIe power connector supplies 75 watts; an 8-pin PCIe power connector supplies 150 watts). The Titan Z has two 8-pin PCIe power ports, so 75 watts comes from motherboard's PCIe slot and 150 watts each per 8-pin PCIe power port = 75 watts +150 watts +150 watts = 375 watts.

    BTW - I'm only running only GTX 590s and 480s on my Macs. I haven't tried to run my Zs on them - that could require Yosemite also for the latest driver support because Nvidia ties driver updates to OS versions.

    Hello there,


    I greatly appreciate your time and the detailed information about the cards, now that I have all the specs, I will make a decision during the following week.


    Thanks.

    Just wanted to bump this quickly and ask if there had been any progress made on this, or if anyone else has some experience/input on a Titan Z in a cMP. I might be picking up a fixer-upper 2010 8c this weekend, and I've been toying with the idea of dropping a Titan Z inside one at some point for various purposes.
