Thank you for talking the time to test and post this, very helpful.

- Do not worry about ECC.
- Luxmark 3 fails on some tests, it is a known bug.
- Barefeats test with the driver might be a fluke, there should not be such a huge gap between PNY and EVGA, GPU processor are the same.
- GTX 980Ti is good at managing power, the fans will kick in when needed, I noticed the same thing with my GTX 980Ti. Nothing wrong here.

So we can conclude from your tests that GPU speed does matter with FCPX. I understand that you have poor playback performance in FCPX with the Nvidia card. Could you please elaborate?
 
Hello to all,
in recent weeks I'm looking in the forums to have a clear and precise answer.
If I install on my mac pro a GeForce GTX 980 without firmware apple, what happens?
After starting the card you are recognized?

First of all: get a version of the card that need 2 x 6 pin power.
Second: Install the NVIDIA Web Drivers for Mac OS FIRST

The card works in Mac OS, but since there's no Mac EFI you will not get a boot screen.
It will only show a screen when the OS / Drivers are loaded. So no image until you get to the Log In screen.
Everything else will work 100%, if you correctly install the NVIDIA Web Drivers.

Hi Kennyman,

Sorry for the late response. It has been a while ago since I did that test. I can't remember what I ment with poor playback, I think the timeline was stuttering.

Since I am here anyway, I would like to speculate about the cause of the poor render time / playback: I recently installed the Caldigit USB3/eSata Pro card, and it caused problems in combination with my blackmagic Decklink 2 duo card (SDI ports), the latter stopped working and caused FCPX to freeze.

This made me think: FCPX uses three internal drives that are in Raid. On this Raid FCP writes the backup, the Media and the cache/renderfiles. Apart from these drives I have two other drives installed in my Mac. What might have caused the problem is that the PCI's in combination with the drives consumed too much energy. Because since I unmounted some of the drives, the Blackmagic Decklink card works fine again in combination with the Caldigit USB3 card.

So maybe I got poor results with the graphic cards with FCPX but not with Davinci Resolve because of too much power consumption of the PCI's / drives combined. Meaning: maybe Davinci doesn't make use of the Raid drives as much as FCP does?

I cannot test it anymore, since I have returned all three GTX 980 cards....
 
$835 just to get a boot screen and a 2.0 that has no real practical improvement is too much. You can get a super clocked version for $550. I know these ROM hacks take a lot of work and deserve respect but if you support hacks like this and TRIM enabler and other kinds of software patches, you are just telling companies like Apple/Nvidia/etc that you don't care about official solutions. Then they won't devote any manpower to the drivers or Mac editions. You will only have yourselves to blame if you do things like that.

Official Solutions... Come on...
Like apple's certified only thunderbolt cables for ios devices and usb super drives that won't work native on a Mac Pro. They create limitations without resolve.
It's up to the people with drive to find alternatives.

Apple isn't likely to devote much attention to producing upgrades for a system that they stopped making over two years ago. I also don't see them as likely to bother to make gamer video cards for the new Mac Pro; that's not their target market.

Dear electronic,

But I read of another problem, namely the purchase of a PCI-E connection to an auxiliary power connector slot.
Ie the mac does not support 2 video cards?

Sorry for my poor English, I am not 100% sure what you talking about. But the cMP do support 2 (or more) video cards. Even Apple provide multiple video card option when they selling the cMP.
 
Although inside the mac I can put up to four video cards,
if I want to install a second video card, I have to purchase the following components?
- PCI-E connector
- Auxiliary power connector
 
in practice if the sum of the two cards into the mac consumption exceeds that of course will jump around.
How do I know the internal power supply?

Knowing the internal power supply capacity is actually rather irrelevant however the Mac Pro internal power supply is 980w.

The more important thing to know is that the Mac Pro provides 75w per PCIe slot via the slot itself, and in addition has two 6-pin PCIe power connections each of which also provides 75w. Therefore a single video card can draw a maximum of 75w + 75w + 75w = 225w in total, and two video cards could draw either 150w each (75w from the slot plus one 6-pin cable each providing another 75w), or you could have one video card getting up to 225w and a second card getting only up to 75w.

If you need more power than this then you need to add a second power supply which could either be an external power supply or one fitted inside the Mac Pro in the optical drive bays area.

Is anyone able to dump the EFI rom of the GTX980 ? The 1080's are coming out on June 29, which will cause the 980's price to drop. It has been too long for everyone to protect MVC's Maxwell EFI rom

Really??? You honestly believe that stealing someone else's work is OK. I assume you pirate movies, songs? What about books? Maybe you want to make and sell your own medical drugs?

And lots of reverse engineering to be done, apple doesn't like to follow standards

I thought there was a hardware modification involved as well - the standard chip isn't big enough to hold the Mac ROM. If that isn't the case then it really is impressive that the ROM hasn't leaked somewhere or been developed by another party.
 
Well, the number of sellers advertising flashed Maxwell cards on eBay clearly shows that the ROM has been leaked many times (it's safe to assume that all of them are based on MVCs/netkas work).

They don't give it away for free either, since they want to make money with it, so it isn't publicly available.
 
You believe that is why Apple does not offer official solutions?

OMG!

Let me say it again, OMG!

Apple hasn't offered any Geforce since the GTX680 mac edition.
They want to force people to buy the new funeral urn version.

Trim enabler isn't needed with Yosemite and El Capitan because you can do trimforce enable

hey just build a hackingtosh, i have done that since the pound has lost a lot of value, so mvc option would be overpriced for anyone in england. i am just patiently waiting for nvidia to update drivers for pascal so i can use the gtx 1070 with osx. fcpx performs well though with the amd 7950 in a cmp.
