Nvidia Rocks ! Titan-X Drivers already in web drivers ! Mac Edition GTX Titan-X !

Don't bother with this card.

Its the card that will be in next Mac Pro. Or at least some variation of it .

Question for MVC...
Can the flashed Titan X do basic display functions without the web driver (for installing web driver, OS updates/reinstalls, etc)? Or is it important to have an OS X driver-friendly card on hand as a spare?

Glad to see it works on internal power, btw.

Yes, that is what EFI does, load a basic driver for display.

So SOME updates will easily be done while the non-EFI cards will be staring at a black screen. Most notably the recent "Security Update" debacles were no real problem for EFI Maxwell cards.

Not to mention, now that 4K SST displays are becoming mainstream, these will be the ONLY cards to still display a boot screen. Even the "legendary" nMP just gives you a black screen until desktop loads on SST 4K. The ONLY Mac Pros showing a 4K boot screen are ones running our EFI Maxwell cards.

Would the titan x still be safe on internal power with 4 HDs 2 SDDs 96GB ram all pci slots full and and upgraded 3.33 dual procs? I'm worried about pushing the limit.

Istat menu show me ~50 Ampere on full load (GPU Furmark + CPU C4D), 80 Ampere are the PSU specifications.

System
Dual 3,33
680 GTX
M.2 SSD PCIe
FASTA-6GU3 Pro
3x HD

A 2 x 6-Pin (like the 680) can pull up 12,5 Ampere
A 6+8-Pin Card (like the Titan) can pull up to 18,75 Ampere.

Hello,

I have a little question for Macvidcards.
Can you measure the consumption of the GTX Titan X during rendering octane render?

 

[Demigod Mac]

Yes, that is what EFI does, load a basic driver for display.

Very nice! Just wanted to make sure there wouldn't be any potential pitfalls if I sold my 780 and got the Titan X. (incidentally, would you be able to do a trade-in deal with one of your older cards?)

 

[benjaprud]

I can confirm the Titan X works without issue (except loud PCIe fan under load - 2000RPM) on 4.1 MP with overclocking and 110% (275W) TDP limit using a 6 to 8 pin adapter, even under Furmark or whatever I throw at it. Those who have additional PCIe cards might hit the PCIe power limit though. I will still make the PSU to PCIe mod for safety (and to lower the PCI and PSU fan speeds). Tested on this setup :

4.1 > 5.1 MP with W3690 / 12 GB RAM
4 HDD + 1 SSD in 2nd optical bay
Titan X GPU (OC 1370/1960 and 110% TDP) with no other PCIe card
1 x 6 pin + 1 x 6 to 8 pin adapter

 

[Demigod Mac]

OK I just bit... ordered one direct from Nvidia. Will send it to MVC for flashing service after it arrives.

Just curious - how does an EFI flashed Titan X behave on a system without the web driver (i.e. before installing it)? Want to make sure if I sell my 780 I won't ever run into a problem if Titan X is the only card I have (like during a clean OS install or repair boot).

Any moment you can boot single user mode (even durring os install), type

nvram boot-args="nv_disable=1"

Then reboot and do installation (or web driver install).

Once web driver installed you can remove that boot flag.

Cool, thanks. So that lets you at least see what's going on and get the necessary installs done. So if say, my OS got corrupted beyond repair and I had to wipe and do a clean install, if Titan X was my only card I could use this method to get things back up and running without needing to swap out a spare OS X driver compatible card?

Now if only an upcoming Mac would use an Nvidia 9xx series... perhaps then we'd see a new OS X native driver...

Got my card flashed by MVC. Some benchmarks:

OS X 780: 49.4
OS X Titan X: 53.6

Windows 8.1 780: 56.4
Windows 8.1 Titan X: 82.4

Large performance disparity between OS X and Windows but that's to be expected. Huge performance improvement on the Windows side.

Metro 2033 Redux 780: 46.58
Metro 2033 Redux Titan X: 82.67

Metro Last Light Redux 780: 54.16
Metro Last Light Redux Titan X: 97.49

Card laughs at everything I throw at it. Only 3DMark 2013 FireStrike Extreme brought it to its knees.

Also it fixed my Apple LED Display boot screen issue in this thread, so that was a nice side bonus:

Let me know if there's a benchmark you'd like me to run on it.

@Demigod Mac

Could you please post Luxmark scores under OSX please? many thanks

 

[Demigod Mac]

Got a lot of variation on the hotel lobby scene so I'll post a few. Luxball was fairly consistent.

Luxmark 3.0

Thank you, nice results! Hard to believe this is from NVIDIA and that is without native drivers from OSX, best of both worlds (CUDA and OpenCL). You should be able to have stable scores once the folks at Cupertino start adding Maxwell drivers to Yosemite, I have a feeling they will definitely go with Maxwell GTX 950M/960M for the upcoming MacbookPro Series along with Intel Broadwell/Skylake

Hope so. Doubt they will go Quadro for the nMP 7,1 (though I'd love to be wrong about that), as part of their war on CUDA.

MBP makes more sense: precedent, plus power+heat efficient Maxwell would be better for a laptop than AMD's offerings.

MVC's flashed card works without the Nvidia driver though. You get a bootscreen and can view the desktop to get the web driver installed, it just moves super choppy until then.

 

[kennyman]

Yes, I really hope they go with Maxwell on MBP, that will motivate Apple to include the Maxwell Drivers on Yosemite. Meaning we will still have some decent support on the OS without having to install web drivers. Thanks for sharing..+1

 

[h9826790]

Is it something wrong? I OC my 7950 to 1076MHz and have the following result. Even though the TitanX is still 19% faster, but should it be more? I think the TitanX is much much stronger than the 7950. Driver issue?

 

[Demigod Mac]

There's a noted performance disparity between OS X and Windows.
Some Windows benchmarks:

 

[Demigod Mac]

I've heard a lot of debate back and forth on slot arrangements, so I'll leave my config here... If anyone thinks rearranging PCIe would get better performance, let me know:

4. OWC Accelsior E2
3. Creative SB-Z sound card
2. USB 3.0 card
1. Titan X

No kext loaded with Titan-X in Netstor

I just got two Titan-X and put them into my Netstor 255A which is connected to a mid 2012 MacPro 5.1 One of the Titans shows up in the system profiler and works correctly while the other one is not recognized and no kernel extension is loaded.
I'm on the latest drivers: 346.01.02f03 for the web driver, and Cuda is 7.0.36 for the K5000forMac which is serving inside the MacPro for GUI purposes.
I am not familiar with scripting kexts - nevertheless I'd try since I need to get that second Titan running. Can anyone give some advice??
Thanks in advance guys!

Hmm, sadly it seems the problem keeps going on, I had the same issue with GTX Titan and Mavericks (and above) with my Cubix, with no proper solution.
Therefore, last year I chose to stay in OS X 10.8.5.
Soon, I will put the titans in a PC, so I will able to jump to Yosemite with a single GTX Titan X or .

Perhaps, if your cards were flashed by Macvidcards, it would work perfectly...
Please let us know the result if you do so.
