I will test it on Thuesday. I'm on holidays until Monday night.
I'm running on external power since I got a 780 from you.
While lots of people had no issues with power, mine kept switching itself of. Got a 5.1 with X5690's.
Never tried the Titan X Maxwell on internal power though...
So I should be fine with the Titan Xp:-)
When running Xp under heaven 4K the Mac shutdown.
What are your CPU's, do you have any other PCI-Express cards installed?
Just tried the Titan Xp on my 5.1 Mac Pro. Cuda-Z shuts down the mac if I use heavy load test mode. I may need to get an external power supply or perhaps use the SATA power connections to PCI-E 6 pin cable and then use the two motherboard 6 pin connectors with an adapter to 8 pin?. Kinda sad, but I still would like to get the Mac EFI bios for the card, any idea when it will be available?
What are your CPU's?
2 x 3.46 GHz 6-Core Intel Xeon
Not looking good, with my 12 Core 5690 I:m also able to shut down using first Titan-X Pascal.
So far 1080Ti has run CUDA-Z in Heavy Load Test for 5 minutes
Kind of scary to be so close to edge.
I'll try with W5690 (Single Hex)
Good news everybody!! Problem solved on my end without an external PSU. I used the 2 SATA power leads on the Optical drive bay to a 6 pin connector. I then used both of the motherboard 6 pin leads and combined them using an dual six pin to 8 pin adapter. After that booted and ran Cuda-Z on heavy load test mode for 30 minutes. System seems stable and did not shut down. Since I don't use the DVD rom drive, this solution is quick and very cheap. I am currently running Dual Six core Xeons at 3.46 Ghz, Four 3.5 inch 6 TB hard Drives. 64 GB or ram dual SM951 drives. So the system is fully loaded. Just need that bios :)
Sounds smart, Luis! You just use standard off-the-shelf connectors? How much power can you draw from 2 SATA leads?
I have done the pixlas mod on my 5,1 12 core x5675.
The new Titan Xp is running great, and heavy load mode, doesnt cause any problems.
I have the 6pin and 8pin both tied together to a heavy cable going directly to the PSU board solder leads. I am not using the logic board 6pin leads at all. The load on the PCI slot shows in iStat as only 1.8amp(21watts) at the highest during heavy load.
Tried Heaven at 4k, with no problems. No shut off, and fans only ramped up slightly. My 5,1 is 2012 with original x5675, 64GB mem, two HD, SD, BluRay, and OWC sata3 pcie card with 850pro. I think you guys with the dual 5690 should consider the pixlas mod, it provides all the power your GPU needs with no stress on the logic board.
Has anyone run two 1080ti cards?
I have two gtx980's running in a single 6 core 3.46 5,1 with no issues 1080 uses the same power so I assume it will be ok.
I got a Nvidia Titan XP card straight from Nvidia. I put it into a 2010 Mac Pro Tower running 10.12.4. I have no other PCI cards installed in the computer. The video card has the 2 power cords running into it as well from the Mac Motherboard.
I installed the beta web drive made for the Pascal GPU's that came out this week.
When I boot the mac it does boot correctly but the computer doesn't recognize the video card, if I view the system from a remote login I can see that the video card is picked up as NVIDIA CHIP 256mb and the system is on just not using the card fully, and my monitors show nothing just black.
So with this Titan XP would it have to be flashed to first run at the full PCI Express bandwidth inside OSX and also why is it not registering in my OS as itself, rather it says NVIDIA Chip 256mb? I know for sure the web driver is enabled when I check the OS remotely by logging in.
99.999% of issues as described are operator error
see blog post about boot loop
driver or power cables
All 14 pins are required, not optional
driver must be installed AND selected
I am not sure if the NEW PASCAL DRIVER - 10.12.4 (16E195) 378.05.05.05f01 works properly for the Titan-X (Maxwell).
The driver upgraded as normal, but I noticed a significant reduction in frame rate on one of my more graphics intensive apps.
I rolled back to 10.12.4 (16E195) 3188.8.131.52f01 and the problem went away. I have a 2012 5,1 - 2x 3.06 Ghz 6-Core Xeon.
Can anyone confirm if the New Pascal Drivers are supposed to be compatible with the Titan-X (Maxwell)?10.12.4 and 64GB Ram.
Yes it also supports Maxwell. There's a new CUDA update that goes with the new web driver, did you install it?
Does the new Titan XP run for you guys at full 5GT speed? or only half link speed in OSX? I have the newest Pascal beta web driver installed in 10.12.4 but the card's only showing up as NVidia 256mb chip, so I have a feeling it would need a EFI flash before it really works correctly in OSX right? Or is that not the case and it should work out of the box from Nvidia perfectly, as long as I have the nvidia beta drive for Pascal installed?
Yes I installed the CUDA update at the same time. The frame-rate drop was quite noticeable and disappeared after the rollback. I'll wait for the next driver update and try again.
eagles99, please read my previous comment
Dave but does the Titan XP run stock without a flash at 5GT speed in OSX in a Mac Pro? I know if someone went to buy a regular PC GTX680 for example and it wasn't flash it won't run at the full PCI speed in a Mac Pro.
Or are these newer cards compatible with Macs right out of the box in terms of PCI bus speed running at full, and the only thing they lack is the boot screen?
